☐ 2) nX INSTALLATION REQUIREMENTS

Before connecting to AC mains power, make sure that the mechanical installation, cooling requirements, wiring, controls, and software are all set to the configuration needed for your particular application. Failure to do so could result in damage to the unit or to other components in the system.

2.1 AC Mains Voltage, Power, and Current Requirements

This amplifier will auto-detect mains voltage at either 120VAC or 240VAC. At nominal 120VAC mains, the allowed operating range is 70VAC to 135VAC to allow for brownouts or power surges, and for 240VAC the operating range is 140VAC to 270VAC. Use only the provided AC cord or equivalent to connect to AC mains. Programmable Power-On Delay is available on nXe and nXp series amplifiers. All nX models have a fixed, non-defeatable warm-up delay of about three seconds to protect against excessive in-rush current when first powered up or when waking from sleep. The model number and power consumption are indicated on the back panel label placed above the AC inlet. To reduce the risk of ground loop hum, all sound system ground references should originate at the same AC power distribution point. Do not lift or remove the amplifier power cord ground pin.

AC Mains Connector Types - The following table shows the AC mains plug type supplied with each nX amplifier model, as well as the required receptacle. A detachable 20A Neutrik PowerCON ^ mains chassis connector is installed on all models except for nX 3.04, which uses a 30A PowerCON ^ .

2.2 Input Signal Wire

Use shielded wiring for balanced or unbalanced audio signals. Shielding which is properly grounded will protect the signal from outside electrical interference such as RF, fluorescent lighting, and computer/display emissions. Unbalanced or single-ended (tip-sleeve) lines of less than 10 feet are generally ok, but for greater distance or noisy field environments, always use balanced signal.

Each channel's Euroblock, 1/4" phone jack, and XLR inputs are wired in parallel, with XLR pin 2 (+) and pin 3 (-). When using an unbalanced input, wire the hot signal to the input (+) euroblock pin, phone jack tip, or XLR pin 2, and also be sure to wire the input (-) pin, phone jack ring, or XLR pin 3 to ground. Do not leave the (-) input unconnected. Avoid running low level signal wires in close proximity or parallel to long speaker cables, AC power cables, or power transformers, as they can induce hum or oscillation.

2.3 Output Speaker Wire

Note: The sound system installer is responsible for using loudspeaker wiring that is in compliance with local electrical code. The following recommendations for speaker wiring are based on UL 60065 section 5.2-d and the US National Electrical Code Article 725. These are only guidelines, consult your local code for specific up to date requirements.

Class 2 wiring is typically used when the maximum measured open-circuit speaker output voltage is less than 120V r.m.s. Class 3 wiring is typically used if the measured open circuit output voltage exceeds 120V r.m.s, such as when 70V, 100V, or low-Z amplifiers are used in bridged mode.

Output Speaker Connectors: nX amplifier speaker outputs use Neutrik SpeakON connectors because they are safe, secure, reliable, and fully enclose any hazardous voltage.

Wire guage: nX amplifiers are capable of delivering high levels of output current, so the wire gauge used for speaker outputs is important. Inadequate wire gauge, especially over long distance, adds significant resistance to the speaker's own impedance, reducing the power which is actually delivered to the speaker. It could also result in a decreased damping factor and potential fire hazard. Since power at the speaker load is of primary concern in system design, refer to the table below to best determine appropriate wire gauge for your application. The following table lists the resistance per 100 feet of common copper wire gauges, and also lists the percentage of the speaker load power which would be lost as heat in an arbitrary 100 ft run of different gauges of 2-conductor copper speaker wire.

Wire gauge resistance/power loss for 100ft speaker cable

Wire Gauge Ohms/100ft 8 Ohm load 4 Ohm load 2 Ohm load

8 0.0605 Ohms 0.8% 1.5% 3%

10 0.1018 Ohms 1.3% 2.5% 5%

12 0.1619 Ohms 2.0% 4.0% 8%

14 0.2575 Ohms 3.2% 6.4% 12.8%

16 0.4094 Ohms 5.1% 10.2% 20.4%

18 0.6510 Ohms 8.1% 16.3% 32.6%

This table expresses the power loss as a percentage of the load's power rather than the total amplifier output power in order to accurately determine power loss at other cable lengths. For example, if you plan to deliver 150 watts to an 8 Ohm load through 50 ft of 14 ga. cable, the power loss in the cable would be half that of a 100 ft run of #14 wire as shown in the table, or 1.6% of 150W, which is an insignificant 2.4 watts. However, if you were to run 200 ft of 18 ga. cable to a 2 Ohm load, the loss would be twice that of the 100 ft run shown in the table, or 65.2% of 250W, which is 163 watts lost as heat. Always be sure to use adequate gauge speaker wire.

2.4 Remote Control Wire

Remote DC level control (all models) - Unshielded bell or telephone wire is sufficient for DC level control, as is CAT5 cable. The V+ and GND pins from one amplifier channel can be shared with other remote DC level controls wired to the same amplifier, however do not connect this ground to any external grounds.

Remote Standby (nXe and nXp only) - This is a logic level signal, use unshielded low gauge wire.

Fault (nXe and nXp only) - This is also a logic level signal, unshielded low gauge wire is adequate.

Preset (nXe and nXp only) - This is also a logic level signal, unshielded low gauge wire is adequate.

Data (nXe and nXp only) - Four conductor telephone wire is suitable, as well as CAT5, but if shielded wiring is used be sure to ground the source end of the shield. Under no circumstances should shielding be left unconnected to ground, as the added line capacitance will degrade the data signal. Maximum data cable distance is 1,000 ft (305m).

2.5 Aux Output Wire (nXe and nXp only)

The aux outputs are pseudo-balanced, meaning they use single ended signal (+) but with balanced impedance, and can be wired balanced or unbalanced. Always use shielded cable for audio signals.

2.6 Mechanical

Each amplifier model is 2RU, and is designed to fit in a standard 19-inch equipment rack. Use four screws when mounting the amplifier to the front rack rails. Rear support is recommended for mobile or touring use (see mechanical drawing below). In some installations where the sound system is exposed to a high level of RF noise or system-induced oscillation, it may be necessary to ground the amplifier's chassis to the rack enclosure. This is accomplished using star type lockwashers on the four rack mounting screws, placed between the amplifier chassis and the rack rails. These star washers will penetrate through the amplifier and rack rail finish to adequately ground the chassis to the rack.

2.7 Cooling

Air vents on the amplifier front and side panels must have access to free flowing room temperature air. Cool air is drawn in through the sides and blown out the front. It is not necessary to leave empty rack spaces above or below the amplifier. See the BTU/hr chart below for amplifier thermal output characteristics.

☐ 3) nX AMPLIFIER PROTECTION

Power-On Delay - All models have a fixed and undefeatable warm-up delay of three seconds when first powered on or awakened from sleep. This is necessary to prevent excessive in-rush current during start-up. Additionally, nXc and nXp amplifiers have programmable Power-On Delay ranging from zero to 25 seconds in 100ms increments.

Thermal Protection -Cooling fans are continuously variable, increasing in speed as the amp heats up. The fans are at their maximum speed when an amplifier channel reaches 80% of its safe operating temperature, and the Temp LED also turns on. At 90%, the Protect LED turns on to indicate that countermeasures are being applied to attenuate the input signal to the overheating channel. A Temp LED turns on dim at first, then increases in brightness as the amp channel approaches maximum safe temperature. 100% critical temperature will shut down the amplifier.

Overpower Protection - To protect internal components against overpower conditions, a protection scheme in each output stage reduces audio output power until the fault condition is no longer present.

Output DC and Rail Fault Protection – Output DC on any channel will trigger the Protect LED and mute that channel. Voltage rail irregularities such as power supply pumping are also detected and compensated for in real time as the amp runs.

4.1 Mounting Holes – For mounting to a 19" equipment rack.

4.2 Air Vents - Cool air enters in through the amplifier sides and is vented out the front.

4.3 Factory Reset/Sleep Mode/Disable Switch – This recessed switch is used to perform a factory reset. It is also used to set sleep mode and front panel disable status (see below). To perform a factory reset and return all amplifier settings to their original factory defaults (without erasing presets) use a pencil point or equivalent to press and hold the switch during power up until all channel LEDs sequence from bottom to top. Releasing the switch before the LED sequence is complete will cancel the process. Upon completion, all LEDs turn off and the amplifier resumes normal operation.

Setting Sleep and Front Panel Disable Mode - The factory reset switch is also used to select one of four sleep and front-panel-control-disable modes as illustrated to the right. The default status is Sleep and Disable OFF (Mode 1). To advance to the next mode, press and hold this switch when the amplifier is fully on, and the four mode combinations will cycle and repeat. To select a mode, simply release the switch when the desired mode is displayed.

The Disable LED is lit any time the front panel controls are disabled, either by selecting disable mode from this switch or using software control.

The sleep LED turns on during the mode-select cycle whenever sleep mode is enabled, but turns back off as soon as the switch is released, remaining off unless the amp actually goes to sleep. The current sleep mode status can be displayed when the amp is fully on by quickly pressing and releasing the reset switch. If the sleep LED lights, sleep mode is active.

4.4 Channel Attenuators - These control the input signal level to the amplifier, and work in conjunction with the remote DC fader level controls and the software control surface fader controls (if the amp is networked). When an input attenuator is turned fully off, it's red Clip/Mute LED turns on and stays on to indicate mute status for that channel. The front panel attenuators can be disabled, along with the power switch, using the factory reset switch or using software.

4.5 Channel LED Indicators

BRIDGE - This green LED indicates when the channel pair is configured to BRIDGE mode from the back panel switch. Only the odd numbered input and level control for that channel pair is used.

TEMP - This yellow LED turns on when an amplifier channel has reached an operating temperature that is 80% of it's maximum safe range, and the cooling fan(s) are at their maximum speed. The LED lights dimly at first and will glow brighter if the temperature increases.

CURRENT - This green LED lights proportionately with the output current delivered to the speaker load.

SIGNAL - This green LED lights when the output voltage reaches -18dB from full output.

CLIP/MUTE - CLIPPING: The red LED indicates clipping when speaker output is 1dB below rated output, or when the input preamp signal is clipped. MUTE: The LED indicates mute when the channel is muted or when it's level control is fully attenuated. Additionally, the Clip/Mute LED is used along with the Protect LED to indicate an output DC fault.

4.6 Amplifier Status LEDs

PROTECT - The red Protect LED initially turns on to indicate that real-time countermeasures are being applied to overpower, overtemperature, or rail voltage fault conditions while the amp is still running. If those countermeasures are unsuccessful, the Protect LED indicates an amplifier shut-down, and the power must be cycled before resuming normal operation.

SLEEP - This blue LED indicates that the amplifier is asleep. Sleep mode can be enabled as a power saving feature that shuts down most amplifier circuits after a period of audio inactivity, reducing the amplifier's power consumption to less than 1 Watt. An amplifier is awakened when there is audio signal present again, or when the power switch is pressed. Because the real-time-clock is also shut down during sleep mode, the amplifier cannot be awakened by any software function, including the event scheduler.

Sleep mode is normally disabled, therefore must be enabled by the user. On nX series, the sleep clock timer is fixed at 30 minutes, and is enabled by toggling through the four mode conditions of the factory reset switch. On networked nXe and nXp series, the sleep clock timer also defaults to 30 minutes, but is programmable under [Device Options] with a range of 1-120 minutes. In all models, the presence of input signal above -24dBu (0.05Vrms) or pressing the power switch will return the amplifier to normal operation. On all models, a fixed amplifier turn-on delay of three seconds is necessary to manage in-rush current during power-up or waking from sleep. Sleep mode has priority over standby mode.

DISABLE - This yellow LED lights when the front panel power switch and level controls have been disabled. All front panel controls are disabled together using the factory reset switch, or in software using the amplifier's main control surface.

COM - For nXe and nXp models only, this green LED lights whenever network communication occurs. Secondly, the COM LED flashes for two seconds when the software button for that device is clicked. Lastly, the COM LED becomes lit (along with the flashing power switch LED) during flash reprogram mode.

4.7 Power Switch/LED - This switch is used for powering the amplifier on or off or waking the amplifier from sleep. The white switch LED lights solid when the amplifier is on, and flashes when in standby mode (nXe and nXp only). The power switch can be disabled using the factory reset switch, or disabled from software (nXe and nXp only). The three possible power switch LED conditions are:

1) Fully lit: The amplifier is powered up, even if the power switch has been disabled, in which case the disable LED will be on.
2) Flashing: The amplifier is in standby mode, or is in flash reprogram mode when the COM LED is also lit.
3) Fully off: The amplifier is either completely off, or it is in sleep mode, in which case the blue sleep LED will be on.

5.1 Channel Configuration DIP Switch - The DIP switches configure each channel's 80Hz 2nd Order Hipass Filter, Clip Limiter, Amplifier Gain, and Output Mode. In the example to the right, the DIP switch is set as follows: 6: 80Hz High Pass Filter is Off; 5: Clip Limiter is On; 4&3: Gain is 1.4V; 2&1: Output Mode is Low Z.

6 HPF 5 LIMIT 4-3 GAIN 2-1 MODE ON ON 26dB LOW Z OFF OFF 32dB NOT USED DIP SWITCH SETTINGS 38dB 70V 1.4V 100V

Note: The Gain setting of 1.4V means that a 1.4V input will drive the amp to full output in any output mode. The other three Gain settings will apply their respective amplifier gain regardless of output mode, so the actual input voltage required to fully drive the amp will vary based on the selected output mode.

5.1 Channel Configuration DIP Switch

5.2 Euroblock Input Jack - Used for wiring a balanced input. If using an unbalanced signal, wire the input signal to the (+) pin, the shield to (G), and wire the (-) input pin to ground. Euroblock pins are wired in parallel to the 1/4" TRS and XLR combo jack.

5.3 Remote DC Level Control - Each channel has a potentiometer circuit available for remote DC Level Control. The example to the right illustrates a typical DC level control application. There is no limit to wire length, but do not use any other ground source. If multiple remote DC level controls are used for different channels, the same ground and V+ sources can be shared.

5.4 Combo Input Jack - The combination 1/4" TRS and XLR jack (pin 2 hot) is wired in parallel to the euroblock input. Do not float the TRS ring or XLR pin 3, connect it to (-) signal or to ground (if unbalanced).

5.5 Bridge Mode Switch - This switch places an adjacent channel pair into bridge mode, combining two amplifier outputs for more power to a single speaker load. Bridge mode uses only the odd numbered input channel and level control, disabling the even numbered input. Speaker outputs for bridge mode must be wired according to the chart shown to the right. The bridge mode switch button can be removed for added security by pulling it straight off.

5.6 SpeakON® Output Jacks - SpeakON output jacks provide safe, secure, and reliable loudspeaker connections,

while preventing outside contact with potential hazardous voltage. See the speaker wiring diagrams to the right (also on the back panel) for nX amplifier SpeakON pin and channel assignment.

5.7 PowerCON® AC Mains Connector -Always use the AC cord provided by Ashly for connecting to mains power. The amplifier auto-detects mains voltage from 120VAC to 240VAC. WARNING: Do not remove or lift the mains connector ground.

The following nXe features are in addition to standard features found in nX series amplifiers:

6.1 Ethernet Port - This RJ-45 connector offers Ethernet control and monitoring of the amplifier using Protea ^ne software.
6.2 Network Audio - This is for an optional factory installed CobraNet or Dante network audio module on nXe and nXp models.

Close Switch For Standby STBY G +5V EG F1 F2 F3 F4 FAULT (LOW)

6.3 Standby Switch

6.3 Standby - The STBY pin, when connected to the ground pin (G) as shown, will remotely place the amp into standby mode. When the connection is opened, the amplifier returns to normal operation. The front panel power switch will flash when the amplifier is in standby.
6.4 Fault - Four Fault pins are used with adjacent ground (EG) and +5V pins for 5V logic outputs, and are assigned in software to indicate an amplifier fault state. The assignable fault

conditions are overtemperature, rail voltage, and average power, the same conditions that could place the amplifier into protect mode. Logic low (0V) indicates fault condi-

tion. In the first example to the right, a remote red LED is wired to F1 and +5V and turns on when a user-assigned fault condition exists. F1 is normally high (+5V) but goes low (0V) on fault. The second example uses a green LED wired to F2 and EG to indicate no-fault, so the LED remains on unless there is a fault.

In the third example, a relay circuit is driven by the F1 pin in order to switch on a room or rack exhaust fan if the amplifier becomes severely overheated. Maximum fault pin source current is 20mA per pin. Maximum fault pin sink current is 200mA. Use an external +5V supply as shown if sink current exceeds 200mA.

6.5 Preset - Each pin (P1 through P4) can be connected to the adjacent ground pin (G) via Ashly's WR-2 remote or other contact closure to recall a stored preset or

sub preset from the amplifier. Preset pins 1-4 correspond directly to amplifier presets 01 - 04.

6.6 Serial Data Connector - These four pins (G, +18, OUT, IN) are for connecting a serial data remote control such as an Ashly WR-5 or RD-8C. Ashly also offers an in-line converter called the INA-1 which allows the data port to be used with third party RS-232 controllers. A technical RS-232 protocol document is available on the Ashly website for third party developers.
6.7 AUX Outputs - These Euroblock connectors provide preamp signals for driving other amplifiers. AUX outputs are pseudo-balanced, meaning they use single ended signal with balanced impedance, and can be wire balanced or unbalanced.
6.8 AES3 Digital Audio I/O Option - This is used for Ashly's two or four channel AES3 input and pass-through module, available as a factory installed option on nXc and nXp models.

*The following nXp features are in addition to all the features found in nX and nXe series amplifiers:

7.1 Installed DSP - Factory installed DSP allows for comprehensive signal processing and matrix routing of amplifier signals, plus loudspeaker swept load impedance analysis.

7.2 Network Audio - CobraNet or Dante network audio modules can be factory installed in nXe or nXp models.

7.3 AES3 Digital Audio I/O - AES3 digital audio module can be factory installed in nXe or nXp models.

☐ 8) ETHERNET COMMUNICATIONS (nXe and nXp models only)

Ethernet communication is made by connecting the amplifier directly to a PC running Protéasoftware or connecting through a network router, switch, hub, or patch panel using Cat-5, Cat-5e, or Cat-6 wiring. Maximum Ethernet cable distance is 100 meters (328 ft). Ashly nXe and nXp amplifiers will adapt to either a straight through pin to pin or crossover Ethernet cable. For wireless iPad control using a custom "Ashly Remote" user interface, the iPad must be connected to a wireless access point that is connected to the same network (subnet) as the amplifier.

8.1 IP Address - There is no need to assign an IP address to nXe amplifiers. The router or Link Local Addressing will assign IP addresses to each device automatically.

When a router is not available, each amplifier will acquire it's 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 device can 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.

8.2 Firewalls - If Protea ^ac software does not detect the amplifier or show real time changes, the firewall in the host PC may need to have Protea ^ac 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.

8.3 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.

8.4 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.

☐ 9) TROUBLESHOOTING TIPS

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?
3) Is the Power-On Delay time set high?
4) Is the amp asleep?

No Amplifier Output

1) Is the amplifier in Standby Mode?
2) Is there signal getting to the amplifier?
3) Is the input signal properly wired?
4) Are output connectors properly wired
5) Are front panel, remote control, or software attenuators turned down?
6) Is the amp channel muted from within the control surface, DSP section, remote control, output mixer, or event scheduler?
7) Are dynamics or gain tool settings in the DSP section allowing signal to pass properly?
8) Is the signal properly routed to the desired output in the DSP Matrix Router?
9) Is the fader level set properly in the DSP Matrix Mixer?
10) If using a DSP crossover on the outputs, are the filter frequency settings correct?
11) Did the event scheduler mute an output, change a preset or output channel source?
12) Is the Amplifier in Protect Mode?

Protect LED is On

1) Does the amp still function, (fans still running)? If so, this means that one or more channels of the amplifier are applying live countermeasures to compensate for an overheated, overpowered, or rail fault condition, and the amp will continue to operate in a reduced capacity until the fault condition is no longer present. Countermeasures include automatic attenuation of overheated or overpowered channels, and power supply treatments for rail fault irregularities.
2) Has the amp shut down (fans stopped) with Protect, Sleep, and Power Switch LEDs all on? If so, this indicates a critical situation where a failsafe fault condition has been tripped, latching the amplifier into its shut-down state until power is cycled. These conditions may be due to internal component failure, so before cycling the amplifier power, first disconnect all speaker loads. The three failsafe fault conditions are indicated as follows:

A) High Rail Fault - If Protect, Sleep, and Power LED are on and one or more channel's Clip/Mute LED is on, there is a power supply overvoltage condition on the indicated channel(s).
B) DC Output Fault - If Protect, Sleep, and Power LED are on and one or more channel's Clip/Mute LED and Signal LED is on, there is a DC Output Fault on the indicated channel(s).
C) High Temperature Fault - If Protect, Sleep, and Power LED are on and one or more channel's Clip/Mute LED and Temp LED is on, there is a high temperature fault on the indicated channels that could not be compensated for using countermeasures.

In all cases, if the Protect, Sleep, and Power Switch LED remain on after cycling power, the amp requires servicing.

Clip/Mute LED Stays On

1) Is the front panel level control, Remote DC Level, or software control surface fader fully off?
2) Is the amplifier muted from software, a remote control devices, or an event scheduler action?

Attenuators Don't Work

1) Are the front panel or remote attenuators disabled?

Amplifier Not Recognized in Protea ^ne Software

1) Is the PC successfully communicating with the network?
2) Is the amplifier successfully communicating with the network?
3) Does the amplifier name appear as green text in the Ashly Network device tree?

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.
5) Was the amplifier IP address auto-detected (recommended) or manually assigned?
6) Is firewall software blocking initial communication from the device?

Unable to Access Software Functions

1) Is the 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?
2) Graphic Equalizers have a much greater DSP "cost" than Parametric Filters. The Feedback Suppressor uses even more DSP than the Graphic EQ. Use only as much EQ as is needed.
3) Speaker Delay uses less resources than Delay

Can't Use Any DSP Tools On Input or Output Channels

1) Has Input, Mixer, or Output channel DSP been disabled under Device Options?

Event Scheduler Action Does Not Work

1) Does the amplifier's date/time match that of the PC running software?
2) Did you click the [Update Event] button after editing events?

Remote Control Troubleshooting

WR-5 or RD-8C Doesn't Work Properly

1) Is the remote wired correctly to the amplifier Data connector?
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?
3) Is the remote assigned its own unique device ID from within its device window?
4) If using WR-5 for gain control, is there a (ne)WR-5 Remote Gain function in a DSP gain block on the channel to be controlled?
5) The remote and it's data signal can be negatively affected by static discharge when touched. Refer to the remote owner's manual for proper earth grounding.

neWR-5 or FR-8/16 Doesn't Work Properly

1) Is the remote successfully communicating with the network?
2) Is the remote connected to a switch, hub, router, or power injector providing sufficient Power Over Ethernet (PoE), or using an external power supply?
3) Is the remote assigned within its device window to control the desired amplifier?
4) Is the hardware lockout switch being used, disabling all buttons?
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.
6) The remote and it's data signal can be negatively affected by static discharge when touched. Refer to the remote owner's manual for proper earth grounding.
