About Ashly

Ashly Audio was founded in 1974 by a group of recording engineers, concert sound professionals, and electronics designers. The first products were elaborate custom consoles for friends and associates, but business quickly spread to new clients and the business grew. The philosophy we established from the very beginning holds true today: to offer only the highest quality audio tools at an affordable cost to the professional user – ensuring reliability and long life. Many years later, Ashly remains committed to these principles.

Unpacking

As a part of our system of quality control, every Ashly product is carefully inspected before leaving the factory to ensure flawless appearance. After unpacking, please inspect for any physical damage. Save the shipping carton and all packing materials, as they were carefully designed to reduce to a minimum the possibility of transportation damage should the unit again require packing and shipping. In the event that damage has occurred, immediately notify your dealer so that a written claim to cover the damages can be initiated.

The right to any claim against a public carrier can be forfeited if the carrier is not notified promptly and if the shipping carton and packing materials are not available for inspection by the carrier. Save all packing materials until the claim has been settled.

2. PEMA AMPLIFIER MODELS

2.1 Product Overview

The Pema series of amplifiers are available in the following 120 VAC or 230 VAC mains configurations. Each model can have an optional factory installed CobraNet or Dante network audio module. Constant voltage amplifiers can include 25V, 70V, and 100V output models.

Pema 4125 - Eight input, four 125W amp channels, low Z (speaker), or constant voltage (High Z) output models.

Pema 8125 - Eight input, eight 125W amp channels, low Z (speaker), or constant voltage (High Z) output models.

Pema 4250 - Eight input, four 250W amp channels, low Z (speaker), or constant voltage (High Z) output models.

Pema 8250 - Eight input, eight 250W amp channels, low Z (speaker), or constant voltage (High Z) output models.

2.2 Installation Requirements

Each Pema model is 2RU, and weighs <22 pounds (10kg). The model number, mains voltage, and power consumption are indicated on the back panel beneath the AC inlet.

Caution: Before mounting or wiring the unit, always disconnect it from the mains. Use four screws when mounting the amplifier to the front rack rails. Rear support is also recommended, especially for mobile or touring use. Air flow vents for cooling the amplifier require the front panel to have access to ambient room temperature air. Cool air is drawn in from the front and blown out the sides. It is not necessary to leave a space above or below the amplifier in the rack. To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. Before connecting to mains power, make sure that the controls, software, and wiring are all set to the configuration needed for your particular application. Failure to do so could result in damage to the unit or other components in the system.

Wiring: Always use high quality shielded cable for input signals, and use balanced input signal when possible. To avoid possible system noise or oscillation, avoid running low level signal wires parallel to speaker outputs or AC wiring, especially over long distance. Before testing the system, double check all connections and settings. Refer to the specifications section of this manual for input, output, Ethernet, and other amplifier properties to consider during installation.

2.3 Ethernet Communications Requirements

Ethernet communications with this amplifier is made by connecting it directly to a PC running Protea ^® control software, or connecting it to a networked PC through an Ethernet router, switch, hub, or patch panel. Networks using the Cat-5, Cat-5e, and Cat-6 standard will all work with Pema amplifiers. Maximum cable distance is 100 meters (328 ft) from the nearest router, hub, or switch. Ashly network amplifiers and remotes will auto detect their Ethernet connection, and adapt to either a straight through pin to pin or crossover Ethernet cable.

2.3a IP Address - There is no need to assign IP addresses to Pema products used with a PC or a network router. The router or Link Local Addressing will assign IP addresses to each product automatically.

When a router is not available, most current Pema and NE products have the capability to assign their own IP address based on Link Local Addressing. This allows the device to operate without the need to set up static IP address. If the only option is to use an Ethernet switch instead of a router, and communications problems remain which cannot be solved with the use of the link local standard, each Pema device must have a static IP address assigned from within Protea ^™ software. This is done by selecting “Manual Configuration” in the Network Properties tab of each device, where the system/network administrator must assign each product its’ own unique static IP address, each with the appropriate sub net if applicable.

2.3b Firewalls - If Proteca ^ae software does not detect the amplifier or show real time changes, the firewall in the host PC may need to have Proteca ^ae software added to its firewall exceptions, since firewalls may block the amplifier response to the PC. The current PC firewall status is found by clicking on the Windows Start button, then Control Panel, then double clicking on the security shield where firewall exceptions are configured.
2.3c Wi-Fi and LAN – For the initial device auto-configuration process, any secondary Wi-Fi connection should be disabled on the PC, and the LAN (Local Area Network) connection must be enabled on the PC. Secondary network connections may confuse the auto device discovery process. Go to the Windows Control Panel, then Network Connections, to disable any secondary network connections. Once communications with the device is established, secondary network connections can be enabled again.
2.3d Connecting Device(s) - Connect the Ethernet cable from the PC or network to the amplifier. If a successful Ethernet connection has been made, a solid green LED (Link) lights up on the amplifier's RJ-45 Ethernet port. If there is no green LED showing, there is either a problem with the cable or the network source which must be addressed before proceeding further. All RJ-45 Ethernet ports flash green when active, so backtrack through any other cables, routers, or switches to find the problem. The flashing yellow LED (Data) indicates that data is flowing to or from the amplifier.

2. Power Switch - Switches the unit on or off. Note: The power switch can be disabled from Protea ^ne Software.
3. Status LEDs – Indicate status of: Power, Standby, Protect, Power Switch Disable, and Com activity.
4. Air Inflow Vents - Cool air enters here and is vented out through the sides.
5. Channel Controls - Channel control area.
6. Signal LEDs - The lowest LED will begin to light when the output voltage reaches -18dBu below rated output. The Clip LEDs will begin to flash when output voltage is 1/2 volt below the output power supply voltage, or the front end is clipped.
7. Bridge - This LED indicates that the channel pair is selected to BRIDGE mode from within Protea ^ne software, and that only the odd input channel level control is active.
8. Temp and Current LEDs - The Temp LED indicates that the amplifier channel has reached an excessively high operating temperature and will gradually attenuate the signal to compensate. If unable to sufficiently cool the channel, the amplifier will eventually go into protect mode. The Current LED confirms that the amplifier output is delivered to a speaker load.
9. Channel Attenuators - These control the input signal level to the amp, and can be disabled from software.
10. Factory Reset – To reset all internal configurations (including presets and passwords) back to the original factory settings, press and hold this recessed front panel momentary switch during power up until all channel LEDs sequence from bottom to top. Upon reset completion, the LEDs will turn off and the amp will be in normal operating mode.

2.5 Rear Panel Features

1. Ethernet Port - This RJ-45 connector allows Ethernet control and monitoring of the amplifier using Protea ^ne software.
2. Phantom Power Switch - This switch applies +15V phantom power to channel 1-4 balanced inputs. A separate switch is used for channels 5-8.
3. TEL-PBX Switch - This switches between Mic/Line and PBX analog input for channel one only. When switched to TEL-PBX, a 600 Ohm isolation transformer is inserted into the channel one input signal path. This transformer is designed for limited bandwidth audio from a telephone paging system.
4. Balanced Mic/Line Input - This is used for a three wire (G, +, -) balanced analog input, and uses Euroblock connectors. If an unbalanced input signal is to be connected here, wire the signal to (+), the input ground to (G), and connect (-) to (G).
5. Unbalanced Summed Mono Input - This pair of RCA jacks is used for analog line level (-10dBv) input, and sums a stereo signal together for that input. Note: Unbalanced line level sources may reference their outputs to a different ground than the Pema amplifier, creating the potential for ground loop hum. Always use short cable lengths for unbalanced signals, routed away from AC, video, or data cables, and make every effort to use a common grounding point for all devices. In the event there is still ground loop hum, isolate the unbalanced input signal by using an in-line isolation transformer.
6. Digital I/O Slot – Installation of this option allows this amplifier to be part of a CobraNet or Dante digital audio network.
7. Preamp Outputs - These Euroblock connectors provide access to post-DSP preamp signals for each channel, and are used to drive other amplifiers or processors with the same signal that is driving the power amplifier. The preamp outputs are pseudo-balanced, meaning they use single ended signal with balanced impedance, and can be wire balanced or unbalanced.
8. AUX Outputs - On four channel amplifiers only, the four AUX outputs offer additional and independent post-DSP signals for driving other amplifiers or processors. AUX outputs are pseudo-balanced.
9. Euroblock Speaker Connectors - Used to connect the speakers or distributed line transformers, depending on model.
10. Remote Standby - These two contact closure pins are wired to a switch to remotely place the amp in standby.
11. Preset Recall - These four pins (using remote standby GND) can be wired to remote contact closure switches to recall one of the first four amplifier stored presets. Preset recall function is defined within Protea ^ne software.
12. Data - These four pins offer serial data control and can be wired to Ashly remote control devices such as the WR-5 or RD-8C. Ashly also offers an in-line converter called the INA-1 that allows the Data port to be used with RS-232 controllers.
13. Remote Level Control - These pins can be wired to remote 10k Ohm potentiometers such as the Ashly WR-1 for DC level control of individual channels.
14. AC Inlet - Used for the detachable AC cord. Use only the Ashly Audio factory supplied AC cord.
15. Model Information - This sticker tells the model name, mains voltage, and mains power/current consumption.
    WARNING: Do not remove or lift the mains connector ground.

2.6 Amplifier Protection

Ashly Pema amplifiers have the following protection circuits:

Over Current Protection - When the output current exceeds the amplifier's safe operating limits. This occurs in the amplifier output stage.

Thermal Protection - When the internal temperature is below 40^ C the fan runs at its slowest speed. Above 40^ C the speed is increased until it reaches its maximum value. If the temperature exceeds 100^ C, the input on that channel is reduced. If the temperature exceeds 110^ C, the power supply is switched off.

Mains Protection – Protection within the power supply includes: In-rush Current Limitation during power up, Mains Over Voltage Detection, and internal Mains Fuse Protection. To protect the Mains fuse against AC overcurrent due to excessive audio output current, there is a protection scheme indicated on the amplifier front panel and in Protea® software which reduces audio output level until the overcurrent condition is no longer present.

3. PROTEA ^ne CONTROL SOFTWARE

3.1 Installing Software

Ashly Protea ^ne software is included on a CD with each unit. Software updates may become available on the Ashly web site. Autorun will launch the application to install the software.

Proted ^™ Software Main Menu, Menu Tree, and Project Canvas

Once the software has been installed on the computer and Ethernet connections with the amplifier have been made, launch the software. All available Ashly network enabled devices will be automatically detected and displayed in the Ashly Network device tree on the left side of the main software startup window.

Device icons can be dragged onto the project canvas from the device tree, or placed as virtual devices in "Design Mode". In other words, a device icon on the canvas is not necessarily a live product. It may be a virtual device, or a device that is currently off-line. In the device tree, all currently connected and active devices are highlighted in green. Ashly devices which have

been previously installed but are currently off-line or unavailable are highlighted in red. Individual devices can be dragged onto the project canvas to simulate physical rack installation groups. Editing a device can be done from the device tree or an icon on the canvas. All changes made in software are executed in real time on the device.

The software scans for active devices on start-up. The user can manually scan at any time as well with at the bottom of the network device tree. All devices broadcast their availability to the software when they start up.

In addition to detecting which models are currently online, any factory installed options within each amplifier are detected. Dante or CobraNet are the only options available for Pema. The software control surface for each device automatically displays available controls for installed options. Note: The user can find and verify a single physical device on the network by right clicking over the unit's name in the drop down menu or picture on the canvas, and then click , which will flash the Com LED on that unit's face panel for two seconds.

The project canvas is used to visually represent a sound system installation, and can display any of the networked Ashly processors, amplifiers, and remotes used in that system. The user can also place an assortment of isolated control objects such as level faders, single LEDs, meter bars, etc, and map them to specific device functions within that project. Once a control object is placed using , right click on the control object to bring up its properties. Lines, rectangles, text, even image files can be added to create a custom virtual control screen along with individual devices and control objects and be saved in the project. To see all available canvas tools, right click anywhere over open canvas. Checking allows placed objects to be moved around, while unchecking locks all objects in place.

Once Protea ^nc software is installed and devices identified on the network, a new project can be created and saved. A project file represents the physical hardware installation via canvas items plus all device settings. Individual properties are edited in the control surface window (shown below) by double clicking on the specific Pema amplifier.

3.2 Device Options

1) Flash Reprogram Mode - The amplifier firmware can be updated by downloading a new firmware file to the amplifier over the network. Lates firmware updates, if available, can be found on the Ashly website. When the amplifier is put into flash reprogram mode, the power and standby LEDs both turn on and all audio function is suspended until flash reprogram is completed. Note that Flash Reprogram only appears in the device options menu when a live Pema device is connected.

2) Link Group Configuration - Link groups allow the controls for multiple DSP functions to track each other across channels or even across devices. For example - if two different channels or even different device graphic equalizer blocks are linked, any change made to a control within either of the equalizers will result in an identical change to the other. In other words, DSP blocks may be linked within a single device, or across multiple devices (assuming all devices share the network).

Device Options Preset Options Flash Reprogram Link Configuration Power On Delay Sample Rate and Master Clock Selection DVCA Control DSP Enable/Disable Control

3.2 - Pema Device Options

Each device will support up to 16 Link Groups. DSP function blocks may be assigned to these groups in software. Once assigned to a group, all LIKE functions within DSP blocks assigned to a group will track DSP parameter changes. Note that more than one type of DSP function block can be assigned to the same link group. Each link group may be assigned a name by the user, and also be assigned a color for easy identification. For further details about linking, see the online help in Protea ^tes software.

3) Power On Delay - Use this feature to delay the amplifier turning on after power is provided, as well as after the amplifier is turned back on from software standby mode*. Delay is measured in mS, with the limit at 655,350 mS, or about 11 minutes. The power amplifier should always be the last device to power up, after other system components have turned on and stabilized. Note that the amplifier must first be on for this change to take effect. *Power On Delay does not work when standby mode is activated by contact closure.
4) Sample Rate and Master Clock Source Selection - Changes to both of these settings can be made by clicking the box in this menu item. Sample rate can be set to either 48kHz or 96kHz. Note that at 96kHz, the DSP usage doubles, resulting in half the available processing power for filters, delay, limiting, etc. Also note that the Feedback Suppressor cannot be used at 96kHz sample rate. Factory default settings are Auto Selection for clock source and 48kHz sample rate.
5) DVCA Control - This feature is used in conjunction with the DSP tab gain tool called . Use this feature to create up to four gain subgroups as you would on a mixing console. Any input or output channel can be added to one or more VCA subgroups for group gain control. While no external hardware control is allowed for this subgroup, a level fader control object can be added to the project canvas and linked to this named VCA level control.
6) DSP Enable/Disable - This removes from operation the input output, or matrix mixer DSP functions on any channel. When removed audio is passed directly through the stage that has been disabled.

3.3 Preset Options

1) Preset Options - The Preset Options menu in the main device window allows setups to be named, saved to, and recalled from the amplifier device as well as a computer on the network. Presets are a snapshot of all current settings on a given device.

This device will store up to 31 named internal presets, each preset storing control data for all channels and audio functions. Preset names must be 20 characters or less. While working in Protea ^nc software, changes to an individual preset can be saved to the device using , or saved to the PC using . Individual preset files use the extension (*.pne).

3.3 - Pema Preset Options

2) Sub Presets: Instead of saving or recalling an entire preset affecting all device functions, a sub-preset affecting only a user defined sub-set of DSP functions can be created. To create a sub-preset, first check the box labeled in any and all DSP control blocks to be associated with this sub preset, then under the preset options menu click or .

A preset or sub preset can be loaded to the Pema amplifier by one of the following methods:

1) Use Proteca ^® software on a PC connected to the network to recall files saved on either the PC or on the device.

2) Use contact closures to load presets 1-4 from memory by wiring switches to the rear panel contact closure connector.

3) Use an Ashly WR-5 or ncWR-5 remote control.

4) Use the event scheduler

Note: A full preset recall event will overwrite any unsaved changes, so be sure the current configuration is saved before continuing or it will be lost. The device always loads the last working settings on power-up, so as to preserve any changes if the power is accidentally turned off prior to saving a preset. Caution: A new preset may have dramatically different settings capable of damaging sound system components, so be careful not to recall the wrong preset while the system is on.

3.4 Device Control Tabs

The following device control tabs are available for each Pema device. The tabs include Control Surface, Security, Network Properties, DSP, Input Source, Meters, Meter Dynamics, Meters AutoLeveler, Metering, Event Scheduler, and Fault Log.

Front Panel Attenuator Enable/Disable - Disables amplifier front panel attenuator controls. Note: The software attenuators will still reflect the physical position of the amplifier's front panel attenuators, even when they are disabled and not attenuating the signal.

Channel Thermal - This software LED indicator becomes lit when the channel is operating at an excessive and unsustainable temperature.

Channel Protect - This becomes lit when any amplifier channel is switched into protect mode, meaning one or more fault conditions are occurring. Fault conditions include overvoltage, overcurrent, and overtemperature.

Fuse Protect - This means that the amplifier has automatically attenuated the signal in order to prevent an internal non-user-serviceable fuse from blowing.

Rail Fault - This means that the output power supply has encountered a rail overvoltage fault.

Supply Fault - This means there is a general power supply fault. Fault conditions include fuse protect, overtemperature, and overcurrent.

Stereo/Bridged selection - The drop-down selection box above each pair of adjacent channels assigns stereo or bridge mode for that pair. In bridge mode, input signal is automatically taken from the odd channel input and inverted, then sent to the even channel. The even channel controls become disabled. Note that in bridge mode, the even channel software attenuators will still reflect the physical position of the amplifier's front panel attenuators, even though they are removed from control of bridged signal.

Channel Name - This user defined text box names the amplifier output channel. Up to 20 characters can be used.

Clip/Mute LED - This LED shows when the amplifier output is either muted or clipping. Clipping is indicated when the output level is 1/2 Volt below the output power supply rails, and accurately tracks AC line voltage sags. All outputs become muted when the unit is put in standby mode. This LED always shows the same status as the amplifier front panel clip/mute LED.

Mute Button - This button mutes the output channel. Output mute can be controlled by the event scheduler.

Polarity Button - This button inverts the polarity of the output channel signal.

Main Output Channel Fader - This controls the output attenuation. Output attenuation below -40dB mutes the output.

3.4a - Pema Control Surface Channel Functions

Offset Link Group and Offset Faders - A group of output channels can be linked together to attenuate the group as a whole without changing the relative levels of each channel. If a channel is assigned to one of the 16 offset link groups, a colored triangular marker appears on the left side of the main fader graticule for secondary level control of all channels in that group. Left click and drag this marker up or down to adjust the link group level. The main level control faders can not be linked to a group. Note that more than 40dB of cumulative channel attenuation causes the channel to mute.

In addition to the control surface offset link group attenuator control (not the main fader), most DSP functions have a link group check box in their work window to assign a specific DSP parameter to one of 16 link groups if desired. Link groups can be renamed by clicking on any group name and entering the new name then pressing on the keyboard.

Attenuators - These two dials indicate the physical position of hardware level controls on either the amp front panel or the remote DC level control (if present). Note that these will display the position of attenuators even when disabled in software.

Total Attenuation - This indicates the total amount of attenuation being applied to the channel in dB. This is the sum of the following attenuators: main fader, offset link group attenuation, front panel and remote attenuators (if enabled).

Note: The maximum dynamic range of the amplifier is only achieved when the amplifier's attenuators are set to the optimal value. The amplifier's cumulative attenuators (as listed in the above paragraph) are located in the signal path after all DSP processing but before the power amplifier section. The optimal setting is determined by the maximum input signal of +20 dBu (with the attenuators set far down), minus the input sensitivity of +6.2 dBu (with the attenuators set at 0 dB). This equates to approximately 14 dB of attenuation. The amplifier's specified dynamic range is measured with the attenuators set to this optimal setting of 14 dB

3.4b Security Tab

Password protected user access is set up in the security tab. User names and password are stored within the Pema amplifier. User access is defined by the primary user (admin or default). Available security levels are: View only, DSP Output Channels Access, DSP Input Channels Access, Preset Recall Access, Audio Parameter Access, Audio Only Access, IP only Access, and Full Access.

3.4c Network Properties Tab

In this tab, device information includes device type, MAC address, and network connect status. Device network configuration can be set to automatic DHCP (recommended) or Manual Static IP. Advanced Network Configuration allows the user to bypass corporate firewalls and assign a specific port to PEMA for remote setup and monitoring.

The user can visually identify the amplifier on a network by clicking the "Identify Device" button, which lights the COM LED on the amplifier's front panel for two seconds. The amplifier's firmware revision is shown in the hardware configuration section as well. From time to time Ashly may post updated firmware on our website which can be downloaded and then flash reprogrammed to the amplifier. Flash reprogram is found in the device options menu when connected to a live Pema device.

This is also where individual channels can be selected as part of an automix group. The automixer function is a “gain-sharing” type automixer which automatically makes smooth gain transitions on all selected automixer input channels to achieve a constant total system gain. It is designed primarily to automate the mixing of multiple speech microphones to follow the dynamic nature of the speech dialog and attenuate idle microphones. The automixer may also be used in conjunction with the Autoleveler, Compressor or Gate on the input signal paths for more advanced control of varying input signal levels produced by different voices. A Feedback Suppressor function may also be used on the inputs to further help control feedback problems. For a full description of automixer features and setup, read the online help by pressing F1 when in the output mixer window.

4.1d - WR-5 Wiring
WR-5 buttons are programmed from Protea ^ne software after the WR-5 is wired to a Pema amplifier and assigned a
unique ID number in its WR-5 device window. Each button has a status LED. Controlled functions include preset recall/scroll, mute, zone source selection, individual channel and matrix point level control. A windowed mylar pocket is available to insert custom function button labels.
The Ashly RPS-18 remote power supply is required when more than four WR-5 remotes are connected to one Pema amplifier.
4.1e RD-8C or RW-8C Programmable Fader Controller - The RD-8C (RW-8C) are fader controllers which are connected to the Pema amplifier's Data port and phantom powered from the amplifier. Maximum cable length is 1000 ft using #24 gauge twisted pair. The RD-8C is a desktop controller, while the RW-8C is electronically the same but mounts as a wall plate using a standard North American 4-gang electrical box and connects using a Euroblock.. There are eight channels and a master, each with a fader control and an on/off button. Note: Only one RD-8C can be used per amplifier, and use of an RD-8C will exclude the use of the data port for a WR-5. One or the other remote control device may be connected, but not both.
4.1f INA-1 Inline RS-232 Adapter (not shown) - The Pema amplifier Data Port uses a proprietary serial communications protocol which can be converted to RS-232 using the Ashly INA-1 RS-232 adapter. This allows the use of custom designed third party RS-232 controllers.

4.2a Power Switch Disable

When the power switch is turned off the amplifier is completely off, UNLESS the power switch has been disabled from within Protea ^ne software (Control Surface Tab), in which case the power switch on the amplifier has no effect at all. If the power switch has been disabled from software, the Pema amplifier front panel DISABLE LED will be lit. Even if the AC power is removed, the amplifier's internal memory will maintain the  status until changed again from Protea ^ne software. Performing a factory reset will clear and restore all internal amplifier memory to factory settings.
4.2b On/Off/Remote Standby

Pema amplifiers have three possible power states, OFF, ON, and STANDBY, each with a status LED on the front panel. Control for these states is managed by the following:
1) Remote Standby Contact Closure - When the two Euroblock pins labeled "Remote Standby" on the back of the amplifier are wired to a switch and connected, the amplifier goes into Standby mode, meaning the amplifier is active but not fully powered up. For remote standby to work, the power switch must be turned on OR be disabled through Protea ^nc software. Open the switch to remove the amp from remote standby mode.
2) Protea ^nc Software On/Standby - On/Standby in the Pcma amplifier software functions the same as the hardware based remote standby contact closure on the back panel. The software standby control does not override the Remote Standby contact closure control, they both remain active at all times. See Control Surface Tab descriptions on page 11.

3) Event Scheduler - Protea ^ne software offers an event scheduler for key Pema functions including standby mode. With the event scheduler, the installer can assign one or more times of day or days of the week for the amplifier to automatically go into and come out of standby mode, disabling overall function and conserving power during those times when the amplifier is not being used. See the Event Scheduler Tab description on page 16.
4) iPad - A Standby On/Off control button can be part of an iPad design, behaving the same as software standby.
4.2c Remote Preset Recall

A preset file is created when the user has made all required software settings, DSP processing settings, source selection, signal routing, mixing, etc, for a given application using this device. A preset is essentially a snapshot of all current settings on a given amplifier. This Pema amplifier can internally store up to 31 named presets, each preset storing control data for all channels and audio functions. Individual preset files stored on a PC use the extension (*.pmc). While working in Protea ^ne software,
changes to an individual preset can be saved to the amplifier using , or saved to the PC using . Sub Presets (collections of DSP parameters individually selected from software) are saved in a similar fashion.
Presets can be recalled to the Pema amplifier using the following methods:
1) Protea ^nc Software - Use a direct or network Ethernet connection from the amplifier to a PC using Protea ^nc software. Click (Preset Options >Recall From Disk/Recall From Protea) to load a stored preset into the amplifier. 

2) Contact Closure - The four contact closure connections on the amplifier back panel allow for amplifier presets #1-4 (presets already saved and stored in the amplifier memory) to be loaded into the Pema amplifier at the instant a remote switch connected to one of pins 1-4 is connected to its ground pin. 

3) WR-5 - A WR-5 will appear in software as a captive device to its host amplifier. The six buttons on the WR-5 can be programmed to recall a specific amplifier preset, or scroll through a defined list of presets. 

4) neWR-5 - A neWR-5 will appear in the software menu tree as a device on the network, and must be assigned to the Pema amplifier under control. Like the WR-5, the six buttons on the neWR-5 can be programmed to recall a specific amplifier preset, or scroll through a defined list of presets. 

5) Event Scheduler - Protea ^ne software offers an event scheduler for several key Pema amplifier functions including preset recall. With the event scheduler, the installer can assign one or more times of day or days of the week for the Pema amplifier to automatically recall and load a new preset. 

6) iPad - A Preset Recall function can be part of an iPad design.
Caution: A new preset may have dramatically different settings capable of damaging sound system components, so be careful not to recall the wrong preset while the system is on.
4.2d Remote Gain Control

1) WR-1 DC Level Control - The WR-1 remote potentiometer functions as if it were a front panel attenuator but in a remote location. Attenuation from a remote DC level control attenuator is cumulative with all other attenuation for a given channel, including the front panel level control. 

2) WR-5 - WR-5 buttons can be individually programmed to select single or multiple input or output channels for remote gain control. A gain range with a top and bottom limit can also be set for each gain button. Note: To use this feature, a (ne)WR-5 Remote Gain tool must be placed in one of the DSP processing blocks of the channels(s) to be controlled. Refer to section 3.4d, item #2. 

3) neWR-5 - The neWR-5 uses an Ethernet network connection instead of the amplifier's data port. Buttons are assigned gain control function in the same manner as the WR-5. 

4) RD-8C - RD-8C faders are programmed from Protea ^ne software once the RD-8C is wired to a Pema amplifier Data port. The RD-8C will appear in the software Ashly Network device tree as a captive device to the host Pema. Place a Remote Gain function in the Pema DSP tab's input or output to assign fader control for that channel or group of channels. The RD-8C also has a mute button for each fader which will mute all associated channels. 

5) FR-8/FR-16 - FR-8/16 faders are programmed from Protea ^ne software after the remote is connected to the network shared with Pema. The FR-8/16 is found in the software Ashly Network>Ashly Remotes device tree. Assign individual fader control after selecting the targeted Pema amplifier, then select Mixer, I/O Level, or A/B Source Select mode for each fader. Fader Scaling is available to set upper and lower limits. 

6) Event Scheduler - Protea ^ne software offers an event scheduler for several Pema amplifier functions including changes to WR-5 and neWR-5 remote control gain. With the event scheduler, the installer can assign one or more times of day or days of the week for the Pema amplifier to automatically change WR-5 and neWR-5 channel gain parameters.
7) Protea ^nc Software - Real time gain control from software is available using a variety of tools. These include the main amplifier's software control surface using the channel main fader, a single fader gain control placed on an input or output channel, a digital VCA group gain control placed on an input or output, a WR-5 (or neWR-5) gain control, and the output channel matrix mixer function.
8) iPad - Gain controls can be part of an iPad design, including numeric readback labels that indicate current gain status.

1) WR-5/RD-8C - WR-5 buttons can be programmed to mute and unmute single or multiple inputs or outputs. 

The RD-8C has a mute button associated with each fader which mutes those channels associated with that fader. 

2) neWR-5 - The neWR-5 buttons can be programmed to mute and unmute single or multiple inputs or outputs. 

3) FR-8/FR-16 - FR-8/16 buttons by default will mute their corresponding fader channel(s). When a fader is set to A/B Source Select mode however, the button toggles between two different sources and the mute function is disabled. 

4) Event Scheduler - The event scheduler can be set to automatically mute single or multiple inputs or outputs at a predetermined day and time, and likewise can unmute at a different time. 

5) Proteane Software - The user can mute inputs or outputs in real time from within the software control surface, the DSP section inputs and outputs, and the input source section. 

6) iPad - A Mute button can be part of an iPad design.
4.2f Remote Zone Source Selection

1) WR-5 - WR-5 buttons can be programmed to select different input sources for one zone. A zone is typically one or more amplifier output channels driving speakers in a single listening area. In the WR-5 software control surface, select the output channel(s) for the WR-5 zone by clicking . This defines the WR-5 as controller for that zone, and its up/down parameter buttons with LED display will adjust the overall zone level. Next, program individual buttons for selection of input source(s) by setting button function to  and assigning desired inputs.
If Exclusive Source Selection is checked, only the currently pressed button and associated inputs will be active, otherwise multiple buttons will be active together and add or subtract input sources as defined.
To allow input source selection but not zone level changes, click the . The output level can still be adjusted from software, but the WR-5 is locked out from making zone output level changes.
2) neWR-5 - The neWR-5 offers the same zone source selection capabilities as the WR-5, with the addition of programmable limits on output gain level. 

3) Event Scheduler - Use the event scheduler 
 feature to enable or disable a single input source on a specific Pema amplifier output or AUX output.
5. TROUBLESHOOTING

No AC Power

1) Is the detachable AC power cord properly installed? Is it plugged into a known live outlet? 

2) Has the Power switch been disabled in software? (sec 4.2a) 

3) Is the amplifier in Standby Mode? (sec 4.2b) 

4) Is the Power On Delay time set excessively high? (sec 3.2)
Amplifier Not Recognized in Protea ^ne Control Software

1) Is the PC successfully communicating with the network? (sec 2.3) 

2) Is the amplifier successfully communicating with the network? (sec 2.3d) 

3) Does the device name appear as green text or red text in the left side menu tree? If red, the amplifier is unpowered or offline. (sec 3.1a) 

4) Is the amplifier device icon placed on the software project canvas a virtual device instead of a live amp? Any virtual device MAC address will always read FF-FF-FF-FF-FF-FF. (sec 3.4c) 

5) Was the amplifier IP address autodetected (recommended) or manually assigned? (sec 2.3a) 

6) Is firewall software blocking communication from the device? (sec 2.3b)
No Amplifier Output

1) Is the Amplifier in Protect Mode? (sec 2.6) 

2) Is the input signal properly wired to either a mic/line input or summed mono RCA input? 

3) Are front panel, remote control, or software control surface attenuators turned down? 

4) Is the signal muted from within the control surface, DSP section, input source select, remote control, output mixer, or event scheduler? 

5) Are dynamics and any gain tool settings in the DSP section allowing signal to pass properly? 

6) Is the signal properly routed to the desired output in the DSP cross point matrix? (sec 3.4d) 

7) Is the level fader set properly in the DSP output channel mixer? 

8) Did the event scheduler change a preset or the output channel source? (sec 3.4g)
Attenuators Don't Work

1) In the device software control surface, are the front panel or remote attenuators disabled?
Unable to Access All Software Features

1) Is desired level of access granted to the current user in the security tab?
Unable to Load Enough DSP Tools

1) Is the sample rate set to 96kHz? (sec 3.2) 

2) Graphic Equalizers have a much greater DSP "cost" than Parametric Filters. Feedback Suppressor and FIR filters use even more DSP than the Graphic EQ. Use only as much EQ as is needed. Note that FIR filter and Feedback Suppressor are mutually exclusive for a given DSP channel I/O, meaning only one or the other can be plugged into that channel number.
Can't Use Any DSP Tools On Input or Output Channels

1) Has Input, Mixer, or Output channel DSP been disabled under Device Options? (sec 3.2)
WR-5 Doesn't Work Properly

1) Is the WR-5 wired correctly to the amplifier Data connector? (sec 4.1c) 

2) If the WR-5 is the last one in series, even if it is the only one used, is the two pin jumper properly placed on the circuit board header as shown? (sec 4.1c) 

3) Is the WR-5 assigned its own unique device ID from within its device window? 

4) If using WR-5 for gain control, be sure to install a (ne)WR-5 Remote Gain function in a DSP gain block on the channel to be controlled
neWR-5 Doesn't Work Properly

1) Is the neWR-5 successfully communicating with the network? (sec 2.3d) 

2) Is the neWR-5 connected to a switch, hub, router, or power injector providing sufficient Power Over Ethernet (PoE), or using an external power supply? (sec 4.1e) 

3) Is the neWR-5 assigned within its device window to control the desired amplifier? 

4) Is the neWR-5 hardware lockout switch being used, disabling all buttons? (sec 4.1e) 

5) If using neWR-5 for gain control, be sure to install a (ne)WR-5 Remote Gain function in a DSP gain block on the channel to be controlled
