Frequently Asked Questions - DMP1616 PHONIC

How do I connect the DMP1616 to my computer for remote control?

Connect a standard CAT5 Ethernet cable from the DMP1616's rear panel Ethernet port to your computer or network switch. Install the Asystems control software (download from their website). You can either set a fixed IP using the rear panel DIP switches and UNIT ID rotary, or use DHCP by setting DIP switch PIN 2 to OFF for software-assigned IP. Launch the software, click 'Scan' to find the unit, and log in with default credentials (User: USER_1, Password: ASYSTEMS).

How do I restore factory default settings?

Unplug the power cable. Set DIP switch PIN 7 to ON. Reconnect power and wait for startup to complete. Then set PIN 7 back to OFF. This restores all settings including user accounts to factory defaults.

What is the difference between DMP1616 and DMP1616D?

The DMP1616D includes a pre-installed Dante expansion card for multi-channel network audio transmission. The standard DMP1616 does not have this card but has an expansion slot for optional Dante or other I/O cards.

How do I set the IP address using hardware?

Set DIP switch PIN 2 to ON (hardware mode). Then use DIP switch PINS 3 and 4 to set the first hexadecimal digit (0-3) and the UNIT ID rotary switch (0-F) for the second digit. The combination forms the last octet of the IP address. For example, to set 192.168.0.21, set PINS 3=ON, 4=OFF (value 1) and rotary to 5 (value 5) for hex 15 = decimal 21.

How do I update the firmware?

Set DIP switch PIN 1 to ON (firmware upgrade mode). Connect the unit to your computer via Ethernet. Open the Asystems Audio Device Workshop software, go to 'Flash Programmer' menu and select 'Launch Flash Programmer'. Choose the firmware file from the Asystems website and start the update. Do not power off until the process completes. After update, set PIN 1 back to OFF.

What should I do if there is no output signal?

First, check that output channels are turned on and not muted. Verify routing: inputs must be assigned to outputs in the DSP page. Ensure input and output levels are adequate and no excessive compression or limiting is applied. Also confirm that the power switch is enabled (front panel or software). If using Dante, check Dante Controller routing.

How do I use the RM-4 remote preset controller?

Wire the RM-4 to the GPIO IN port on the rear panel (pins 1-8 for presets, ground pins). In the control software, go to Global Settings > GPIO > Preset. Assign a scene number (saved in Utility menu) to each port corresponding to a RM-4 button. Up to two RM-4 units can be connected for a total of 8 presets. Pressing a button on the RM-4 will recall the assigned scene.

How do I enable the automatic mixer?

On the DSP page, activate the 'Auto Mixer' button for the desired input channels. This links the ALC (Automatic Level Control) and Ducker functions. Then you can adjust ALC parameters in the system settings. The auto mixer manages gain sharing and ducking automatically.

Can I use condenser microphones with the DMP1616?

Yes, the DMP1616 provides +48V phantom power. In the Global Settings > Analog In menu, enable 'Phantom Power' for the input channels that need it. Only activate phantom power when using condenser mics; avoid with dynamic mics to prevent damage.

How do I configure the 31-band graphic equalizer?

Apply the 31-band GEQ to an output channel via the DSP page. Then open the processor settings for that channel. Adjust the faders for each frequency band from 20Hz to 20kHz, each with a range of -12dB to +12dB. The Q is fixed but adjustable between 1.6 and 10 in the parameters section.

Pin 3: Hot (+)

GLOSSARY

The following are a few words that may serve you well while reading this manual. These aren't in depth explanations, but should hopefully give you the basics and a place to start.

Balanced Connections - balanced connections offer three conductors, carrying a ground, an in-phase signal, and an out-of-phase signal. Once the two signals are sent from one device to another, the out-of-phase signal has its phase inverted and the two signals are combined. Any interference picked up along the way is removed through to phase cancellation. This allows cables to be run over long distances without collecting excessive noise on the way.

Compressor - a Compressor reduces signals over a user-defined threshold by a user-defined amount/ratio.

Dynamic Processor – is any kind of processor that dynamically – or in real time – adjusts signal properties.

EQ – Equalizer – is a device or process that allows users to boost or attenuate audio signals at specific frequencies.

Euroblock – These types of inputs allow for self-wiring of connections for permanent installations. Check the "Getting Started" section for more information on wiring.

GEQ – Graphic Equalizer – is in essence the same as an equalizer, but this title is reserved for equalizers with more 'bands' than the typical EQ. While a typical channel EQ may only allow for 3 or 4 frequencies to be adjusted, a graphic equalizer may allow for 31 different frequencies.

GUI – Graphical User Interface – this is the remote PC software used for the DMP1616.

HPF – High Pass Filter – a high pass filter will cut or significantly reduce all audio signals below a particular user-defined frequency, allowing – as the name suggests – high frequency sounds to pass through.

High Shelf Filter – the high shelf filter will reduce or increase all audio signals below a particular frequency. The level at which the signal is boosted/attenuated is determined by the user.

Limiter - work just as compressors do; however with an input to output signal ratio permanently set to infinity-to-1.

LPF – Low Pass Filter – a low pass filter will cut all audio signals above a particular user-defined frequency, allowing low frequency sounds to pass through. This is significantly useful when using subwoofer speakers on particular outputs.

Low Shelf Filter – the low shelf reduces or increases the level of audio signals below a particular frequency selected by the user. The level at which the signal is altered is also set by the user.

Network – a network is a series or group of computers that are interconnected so as to share information. In the case of the DMP1616, the network allows for remote operation of the device using our Windows-based computer.

Noise Gate - a noise gate is a dynamic process that turns off or significantly attenuates the audio signal passing through it when the signal level falls below a user adjustable threshold.

Unbalanced Connections – unlike balanced connections, unbalanced connections only have 2 conductors: one for the signal and one for the grounding. This, unfortunately, makes them more susceptible to noise and interference.

DANTE CONNECTIVITY (DMP1616D ONLY)

The Dante expansion card should come pre-installed with the DMP1616D (and is not included with the DMP1616). This is an optional component that is not included on all versions of the DMP1616.

The "Primary" port on the Dante card can be connected to your network router. The Secondary port can be connected to the Primary port of additional units. Alternatively, all units can be connected to the router using their "Primary" ports.

The Audinate Dante Controller can be downloaded through their website (www.audinate.com). This is used to route the network signals from numerous Dante-enabled devices. Each device will show up as its own independent signal with input and output channels listed. All units will be automatically discovered by the software.

Signals can be routed internally using the instructions found in section 5. The actual network input signals received by your DMP1616s are determined by the aforementioned Dante Controller software. It should be noted that each Network input mix can only have a single source assigned to it.

Connecting additional units to your network will automatically be recognized by the software, allowing any of these systems to have their signals routed throughout the network.

In addition to the regular network routing of signals, the Dante expansion cards are compatible with Audinate's

Virtual Soundcard software which allows for recording of audio to the computer and playback of audio from the computer. At the time of publication, this a permanent license for this software is available for \$29.99 through Audinate's website.

The controller software is completely free on Windows 7 (SP1), Windows 8.1, Windows 10, OSX 10.10.5 (Yosemite), OSX 10.11.6 (El Capitan), macOS 10.12 (Sierra) and macOS 10.13 (High Sierra).

GENERAL SETTINGS

RESTORE FACTORY SETTINGS

1. Unplug the DMP1616's power cable.
2. Switch POLE 7 on the rear panel DIP Switches to the ON position.
3. Replace the power cable and power on the DMP1616. Wait for the start up procedure to complete.
4. Switch POLE 7 to OFF.
5. Now your DMP1616 is restored to the factory default settings.

NOTE: A factory restore is particularly helpful in the event that user names and passwords are forgotten. Restoring to factory default settings will restore user names back to default values.

FIRMWARE UPDATE

When performing a firmware update, a few steps need to be followed. First of all, set the first pole of the DIP switch to the upper-most position.

A connection needs to be established between the DMP1616 system and the Windows remote software. After this is done, open the "Flash Programmer" pull-down menu at the top of the Audio Device Workshop software. Select "Launch Flash Programmer" from the menu. Here you can select the DMP1616 firmware (found on the Asystems webpage) and begin the firmware update. Do not turn the computer or DMP1616 off until the firmware update process has completed.

HOW TO SET THE SYSTEM IP ADDRESS

Connecting the DMP1616 to a computer for remote operation requires the user to enter an IP address for the unit. There are two controls that help determined the IP address of the DMP1616 matrix processor. The first is the UNIT ID rotary control, that lets you select 0 – 9 and A – F. The second is the DIP switch located directly beside the rotary switch. The 3rd and 4th poles of the DIP switch can be used to set a numerical value between 0 and 3. These combine with the UNIT ID rotary switch to form a hexadecimal value for the last value of the IP address (as indicated below).

Value The 3rd PIN The 4th PIN

The configurable range for the last digit is 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E and F.

The unit ID configuration mechanism of DMP1616 is developed based on "hexadecimal numeral system". Therefore, a scientific calculator may be required when setting the unit ID of the IP address for DMP1616. Below is the procedure for setting the unit ID:

1. Define the IP address for your DMP1616.
2. Convert the decimal value of the host bits of the IP address to a Hexadecimal value (consult the provided table).
3. Set PINS 3 and 4 on the 8-PIN DIP switch according to the first digit of the converted Hexadecimal value.
4. Set the rotary switch according to the second digit of the converted Hexadecimal value.

Example: To set an IP address of "192.168.0.21" on your DMP1616, the rotary control should be set to 5 and the DIP switches 3 and 4 should be set to ON and OFF, respectively. This sets a hexadecimal value of 15, which - converted to decimal - is 21. Consult the included chart for hexadecimal to decimal conversion.

Device Name: The name of the current device is found here, and it can be adjusted by the user, if necessary.

IP Address: The actual IP address of DMP1616 will automatically be detected and shown here. User can manually adjust the IP address through the rear panel.

Meters

The DMP1616 has three full pages of Meters, including "Meters", "Meters/Dynamics" and "Meters/AutoLeveler." These give real-time details on the input and output signals being sent to and from the DMP1616, as well as offering gain reduction details on compressor and limiters.

Logic I/O

The general purpose interface output is used to remotely control the DMP1616. When properly setup, you can recall presets and/or remotely adjust other properties of the device.

GPIO In

The GPIO In field is for use with the Asystems RM-4 remote preset control. Up to two can be used at any one time (ports 1 to 8). In essence, users can save any number of "scenes" to the device, and use the RM-4 to instantly recall the scene. This is done by saving the scene through the "Preset Options" pull-down menu at the top of the screen.

Presets will correspond to a particular number, and this GPIO In menu can be used to assign the preset number to a "port" for use with the RM-4. For information on wiring the RM-4 control to a particular port, check the appropriate page within this menu.

A name or "Subject" can be assigned to each scene.

GPIO Out

The GPIO output is used for third party controllers.

Analog In

The Analog In submenu in the Global Settings menu offers two simple functions. These are:

Phantom Power: When using any input with condenser microphones, +48V DC of phantom power can be activated right here. Do not activate phantom power unless necessary.

HPF: Users are able to activate a high pass filter through this option, essentially removing low-frequency noise. This is great for use in conjunction with microphones, where low-frequency noise and stage rumble can be removed.

Compressor/Limiter

This menu allows compressors and limiters to be applied to the channel output

Limiter Threshold: This control determines the threshold for the limiter function. This means that no signal will surpass the selected threshold, being 'compressed' at a ratio of infinity:1.

Compressor Threshold: Use this control to set the threshold of the compressor function. Any signals that surpass the selected threshold will be compressed at the selected ratio.

Compressor Ratio: This control can be used to set the ratio for the compressor. The ratio is expressed as :

.

Compressor Attack: This control adjusts the attack time of the compressor, essentially determining the time taken for the compressor to kick in after it passes the selected threshold.

Compressor Release: The release control determines the time the DMP1616 will wait before disengaging the compressor when the signal bypasses the selected threshold.

Side Chain HPF: This allows users to set a high pass filter on these channels to essentially help rid these channels of low-frequency noise.

System

System Clock: This menu allows you to select the internal sampling rate of the DMP1616. Users are able to select between either 44.1 or 48 kHz. You can also choose to take clock settings from the audio networking feature. The ENTER button must be pushed to confirm.

DSP Usage: view DSP usage here (or on the DSP page).

Power Settings: There are three power settings on the DMP1616. The software power can be turned on and off, essentially enabling the DMP1616 to be turned on and off via the software – including event scheduling. The hardware power can be selected on and off, essentially allow the unit to be activated and deactivated using the hardwired switch on the front of the DMP1616.

RM-4 Preset Recall Remote

With a single RM-4 you will be able to recall up to 4 independent presets. The DMP1616 can use up to two RM-4 remotes.

The RM-4 can be wired to the "Preset" section on the rear of the DMP1616.

As shown, there are 8 pins for each of the 4 preset buttons on the RM-4, as well as grounding pins to the left. Each of the 8 pins corresponds with a user-selected "Scene" within the control software. The DMP1616 allows for up to 2 RM-4 preset recall controllers to be connected.

Suggested wiring:

Setup And Operation

To utilize the RM-4, you simply need to assign a preset to each of the buttons. This is done within the Control Software of the DMP 1616. First, enter the "Global Settings" menu and find the GPIO submenu. Here you will find the "Preset" panel (shown below). Each of the pins on the rear of the device will correspond to the Ports listed here. You can then select which "Scene" (or preset) you wish to assign to that port.

Port	Scene		Port	Scene
	No	Subject		No	Subject
1	1		5	5
2	2		6	8
3	3		7	7
4	4		8	8

The pre-saved scenes are all listed within the Utility menu. Scenes can be saved (and recalled) in this menu. The "No" in the Preset window on the GPIO page will correspond with the 'Scene' numbers found here. The Subject in the Preset window will be updated automatically.

A single preset can be recalled at any one time. The button selected on the RM-4 will lock down, releasing any other preset button that may have previously been selected.

SIGNAL PROCESSORS

Below you will find the onboard signal processors of the DMP1616 and information on their use and respective parameter. These can be applied to any of the 8 input or 8 output channels of the DMP1616.

Compressor-Limiter

Compressor Threshold: Use this control to set the threshold of the compressor function. Any signals that surpass the selected threshold will be compressed at the selected ratio.

Compressor Attack: This control adjusts the attack time of the compressor, essentially determining the time taken for the compressor to kick in after it passes the selected threshold.

Ratio: This control can be used to set the ratio for the compressor. The ratio is expressed as :

.

Compressor Release: The release control determines the time the DMP1616 will wait before disengaging the compressor when the signal bypasses the selected threshold.

Limiter Threshold: This control determines the threshold for the limiter function. This means that no signal will surpass the selected threshold, being 'compressed' at a ratio of infinity:1.

Output Gain: This control determines the amount of gain applied to the signal after already passing through the compressor-limiter.

On & Reset Buttons: The on button is, of course, used to turn the Compressor-Limiter on and off, while the reset button will reset all values to default.

Gate

On: This button turns the gate on and off.

Reset: Push the reset button to restore all parameters back to default.

Dynamic Graph: This graph shows the currently set gate properties and how it will affect your audio.

Level Meters: These meters give the input and output level of the gate for the current channel.

Gain Reduction: The gain reduction meter will provide a real-time indication of any reduction in signal caused by the gate.

Threshold: This control will set the threshold of the gate function. Any signals that fall below the set threshold will activate the gate function.

Range: This control sets the amount of attenuation when the gate is closed.

Attack: This control adjusts the attack time of the gate. This is the time the DMP1616 will wait after the signal drops below the threshold before engaging the gate.

Hold: The hold will allow you to select the length of time the gate will remain open after the signal drops below the set threshold.

Release: The release control determines how long the gate will wait before disengaging when the signal rises back above the selected threshold.

Expander

On: This button turns the expander on and off.

Reset: Push the reset button to restore all parameters back to default.

Dynamic Graph: This graph shows the currently set expander properties and how it will affect your audio.

Level Meters: These meters give the input and output level of the expander for the current channel.

Gain Reduction: The gain reduction meter will provide a real-time indication of any reduction in signal caused by the expander.

Threshold: This control will set the threshold of the expander function. Any signals that fall below the set threshold will activate the expander at the user-set ratio.

Ratio: This signal sets the ratio of the expander function. When a signal drops below the threshold, the signal will be decreased by the selected ratio.

Attack: This control adjusts the attack time of the gate. This is the time the DMP1616 will wait after the signal drops below the threshold before engaging the gate.

Release: The release control determines how long the gate will wait before disengaging when the signal rises back above the selected threshold.

Delay

Adding a delay on output can be particularly helpful to help time align drivers within a single cabinet or help avoid delay in larger multi speaker setups. For example, when there are a number of drivers in a single cabinet, typically they're different distances from the front of the cabinet.

The tweeter, typically longer than the woofer, could have its driver 8 inches deeper than the woofer. The problem this creates is the sound from the woofer will be pushed out a fraction of a second before the tweeter, arriving at the wavefront at different times. Adding a 0.6 millisecond delay to the woofer can combat this, essentially making the signal wait for the tweeter to catch up.

Delay: Use this control to adjust the delay time. To the right of the control, the selected delay will be indicated in milliseconds, meters and feet.

Temperature Control: This allows you to set the current temperature for the delay circuit. This allows the DMP1616 to better refine the delay's 'meter' and 'feet' results. The temperature is indicated in both degrees Celsius and degrees Fahrenheit.

On & Reset Buttons: The on button is used to turn the delay circuit on and off. The reset button resets all values to default.

Signal Generator

Type: Select from Pink Noise, White Noise, Sine or sweep waves.

Frequency: Adjust the frequency of the sine wave between 20Hz and 20KHz, as required.

Parametric Equalizers

EQ On/Off Button: This button can turn the Equalizer for the currently selected channel on and off.

Reset: Push the reset button to restore all parameters back to default.

EQ Band On/Off: Use these buttons to turn the corresponding EQ bands on and off. While not named specifically, these bands can be thought of as the low, low-mid, high-mid and high frequency bands on your average 4-band EQ.

EQ Type: For the first and fourth bands on the EQ, users can select the type of curve used for the EQ. Band 1 can be swapped between a normal EQ band (PEAK), low shelf filter (SHELF), and high pass filter (CUT). Band 4 can be selected between an EQ band (PEAK), high shelf filter (SHELF), and low pass filter (CUT). The Low/High Pass Filters will cut frequencies above and below the selected frequencies at 18 dB per octave. High and Low Shelf filters act similarly, but cut frequencies below the selected frequency by the preset level determined by the user.

EQ Parameters: The EQ offers users the ability to view or edit various parameters/properties of their EQ bands, including the Gain (dB), the frequency (Hz/kHz) and the 'Q' of the EQ band.

Meters: Both input and output meters are available for this process, essentially showing the difference in the overall signal level after equalization.

Feedback Silencer

Feedback occurs when the sound from your speakers makes its way back into the mixer through microphones. The audio look causes a high pitch squeal or screech that can easily ruin your performance. Feedback can be removed, however, by reducing or removing the problem frequencies. With a razor-thin filter, feedback can be completely removed without affecting your audio what-so-ever.

The DMP1616 features a 12 filter feedback silencer. This can operate in 2 different modes: Automatic and Manual. When set to automatic, the activated filters will automatically search for and remove feedback. When set to manual, the user is able to adjust the frequency, gain and Q of the individual filters.

Parameters: When the Feedback Silencer is set to "Manual" it offers users the ability to view or edit various parameters/properties of their EQ bands, including the Gain (dB), the frequency (Hz/kHz) and the 'Q' of the 12 filters.

Threshold: Adjusting the threshold will determine the level of signal required for the automatic feedback silencer to kick in.

31-band GEQ

Graphic equalizers are fantastic in live setups where you may need to compensate for room acoustics or other factors. Include a 31-band graphic equalizer on your speaker output signals to better refine your live audio.

Frequency bands: The GEQ's frequency bands can be boost or cut by the user. Frequencies are set at fixed frequencies between 20Hz and 20kHz.

VCA

VCA – or voltage controlled amplifier – allows for multiple mixes to be controlled together while still maintaining their respective offset. The VCA offers four groups for channels to be assigned where each of these individual groups can have their levels controlled together using the VCA faders. This is typically helpful in ensuring things such as vocals or instruments can be controlled without affecting the mix of audio.

Assign: When the VCA is selected for a channel on the DSP page, the channel's signal can be routed or assigned to one of four groups shown here. To assign the group, push the respective button and increase the respective rotary control. This will determine the level of the signal that will be sent to this VCA group.

Meter: These meters will show the input level of the channel as well as the appropriate output level when after the VCA has been applied.

On: Activating the on button will apply the VCA to the appropriate channel.

Fader: Pushing the fader button will bring up a new window that features a fader for each of the four VCA groups. Adjusting these faders will adjust channels in their respective VCA groups accordingly. As previously noted, adjusting a VCA group will still allow the channels to keep the offset between each channel. Each fader also features an on/off button that will activate and deactivate the VCA group.

Divider: I/O with HPF and LPF, 2 or 3-way divider (for output only).

Crossover

Two and three-way crossovers can be assigned to output mixes, using two or three output channels in the process. This menu essentially will allow you to select the corresponding output mixes in addition to one or two crossover points, as applicable.

TROUBLESHOOTING

I don't have any output

Have you activated the output channels? Do you see a signal in the output meters? Have you correctly routed your inputs to channels, turned levels up, and unmuted mixes? Have you applied an excessive compressor-limiter to any input or output signals?

I have a signal, but it's really distorted!

Are any of the Clip LEDs lighting up for input or output mixes? Do any of the signals on your entire audio chain seem excessive? This could include input connectors, channel inputs, matrix outputs.

My devices are not communicating via Ethernet

Are the red and green LEDs on the Ethernet connectors lighting up? Are you using a decent quality Ethernet cable?

My DMP1616 won't communicate with my computer

Are you using a decent quality Ethernet cable? Are your computer and DMP1616 both connected to the same network? Do you have a firewall turned on?

How can I use the RS-232 port?

An RS-232 connection is available on the DMP1616 to allow control information to be sent to the unit without the need of Ethernet connection. Asystems has provided an implementation reference on the website.

Initializing the DMP1616

The DMP1616 can be initialized using the DIP switch on the rear of the device. The left-most pin will allow users to begin initializing the unit. It can be returned to the RESUME position to continue operation.

Why are the front panel VRs not working?

The rear panel has a DIP switch that controls these VRs. If set to the lower position these will be locked and you will be unable to use them.
