Frequently Asked Questions - DMM 8008 FBT
How do I connect the DMM 8008 to a computer?
You can connect via USB (type B), RS485 (RJ45), or Ethernet (RJ45 TCP/IP). Use the included software to control the device. For USB, install the driver from the CD; it simulates a serial COM port.
What is the maximum number of units that can be daisy-chained via RS485?
Up to 64 units can be connected in a chain using the RS485 In/Out ports. Set a unique ID (1-64) for each unit via the system setup menu.
How do I recall a preset in stand-alone mode?
Press one of the 6 front panel preset buttons (1-6). The corresponding preset must have been previously saved via the PC software. The LCD will display the preset name.
Can I use the DMM 8008 with a wall panel controller?
Yes, the optional FBT WP8008 wall panel can be connected via RS485. It can operate as a Zone Controller (single zone) or Global Controller (all inputs/outputs). Requires a 12V DC power supply.
How do I set the IP address for Ethernet control?
Go to System Setup > Tcp/Ip Setup on the front panel. Use the buttons to enter the IP address (e.g., 192.168.0.1). The unit automatically calculates the subnet mask based on the IP class.
What processing is available on each input channel?
Each input offers gain (-127 to +12 dB), phase invert, 3-band parametric EQ (peaking or shelving), a 1st order high/low pass filter, noise gate, and a feedback eliminator using pitch shifting (for Mic inputs only).
What processing is available on each output channel?
Each output includes gain, phase, mute, 5-band parametric EQ, crossover filters (HPF/LPF with selectable slopes), RMS compressor, peak limiter, and delay up to 380.998 ms.
How do I enable phantom power on the microphone inputs?
Phantom power (+48V) is enabled via the PC software. It is a global setting for all Mic inputs. When activated, the front panel Phantom LED lights up. Only use with balanced microphones.
Can I use the digital I/O ports for external control?
Yes, the S1-S4 input ports (TTL 0-5V) can recall up to 4 additional presets. The output ports can be used to trigger external devices. Configure the logic and priority via the PC software.
What is the feedback eliminator and how does it work?
The feedback eliminator uses a pitch shifting algorithm to reduce acoustic feedback. It is available on Mic input channels and can be enabled/disabled per channel via the software. It shifts the frequency slightly to prevent howling.

The DMM 8008 is a high performance 8 input x 8 output digital matrix mixer; specially designed for commercial and professional applications such as conference rooms, auditoriums, sport utility buildings, house of worship, pubs and disco. It includes 8 independently switchable Line/Mic inputs with Phantom power supply, 8 line outputs, managed by a powerful 48kHz / 24 bit DSP engine, in addition to high performance 24 bit AD/DA converters. The DMM 8008 supports a full matrix mixing mode where inputs may be routed/mixed in any ratio to any output. Each Mic/Line input channel provides Lo/Hi pass 1st order filters, 3-band parametric EQ, Noise Gate function and Gain control. In addition Mic inputs include a Feedback Eliminator function, based on a powerful «pitch shifting» algorithm, particularly suitable for voice applications. Automixing function automatically adjusts input level to make operating easier using either NOM (Number of Open Mics) attenuation function or Gain sharing algorithm. In addition Ducking process enforces a «priority order» of open microphones in order that high priority inputs attenuate lower priority inputs. Each output offers up to 5-band of parametric equalization, crossover filters, RMS compressor, Peak limiter, Phase and Delay controls; 8 digital In/Out ports are provided for general purpose (preset recall, trigger third parts or device); 8 front knobs provides a quickly way to control input Gain; Up to 32 units can be managed by software applications.

<h1 id="141-inputs">1.4.1 INPUTS</h1>
Connect line-level signal sources, e.g. the output of a preamplifier or of a mixer, to the screw terminals INPUTS CH1-CH8 (16). The connections are provided for balanced signals. To connect unbalanced signal sources, connect the contacts «-» and «gnd». Alternatively, connect microphones to these terminal screws. Use the computer to configure the respective input as a microphone or line input. This procedure can also be used to provide all microphone inputs with a phantom power supply of 48V. In this case, only microphones with balanced signal outputs can be connected. Microphones with unbalanced outputs may be damaged by the phantom power supply.
<h1 id="142-outputs">1.4.2 OUTPUTS</h1>
Connect the amplifiers, monitoring systems or other units for further signal processing to the screw terminals LINE OUTPUTS Ch1 - Ch8 (15).
<h1 id="143-general-purpose-io">1.4.3 GENERAL PURPOSE I/O</h1>
Use the four switching inputs to retrieve special configurations (extra programs). Connect the units that are to be used as switching units to the screw terminals INPUT PORT "S1" to "S4" (14) and the corresponding ground terminals. A switching voltage of +5V is required. The logic type and the priority between the four inputs can be configured via the computer. Four switching outputs with a switching voltage of +5V are available for controlling other units. Connect the switching inputs of these units to the screw terminals OUTPUT PORT "S1" to "S4" (13) and the corresponding ground terminals "gnd".
<h1 id="144-wall-panel-wp-8008">1.4.4 WALL PANEL WP 8008</h1>
The wall mount control panel WP 8008 (separately available as an option) allows users to operate the DMM 8008 by two configurable modes: Zone controller (only a single zone can be managed) and Global controller (can be managed all inputs and outputs).
Connect the terminals "485+" and "485-" located on the rear side of the operating panel to the appropriate contacts of the jack RS485 IN (11); to supply power to the control panel, connect the terminals "+12V" and "GND" to a regulated, unearthed DC voltage source of 12V (observe the correct polarity!).
Note: in order to enable the control panel to establish a data connection to the DMM 8008, only switch on the power supply for the control panel when the DMM 8008 has already been switched on. For mounting the control panel use a standard 503 recessed box.
<h1 id="145-computer-2">1.4.5 COMPUTER</h1>
To operate the DMM 8008 by remote control via a computer, connect the computer to the jack (6) using a USB cable. Alternatively, the unit may also be controlled via the RS485 interface (provided the interface is not to be used for connecting the control panel WP 8008) or Ethernet. To control the DMM 8008 via the RS485 interface connect the RS485 output of the computer to the jack RS485 IN (11); the pin configuration is:
The output jack RS485 OUT (12) may be connected to the jack RS485 IN of an additional DMM 8008. Thus, up to 64 units to be controlled may be connected in a chain. If multiple units are connected and if longer control lines are used, the control output of the last unit in the chain should be equipped with a terminal resistor (120 Ohm resistor between pin 1 and pin 2 of the connection) to prevent interference while signals are transmitted.
To operate the DMM 8008 by remote control via Ethernet, the jack TCP/IP (10) may be used to connect the DMM 8008 to an individual computer, a local computer network or, e.g. via a router, to larger computer networks (internet). Network technology expertise is indispensable for the correct installation of the connection.
<h1 id="20-operation">2.0 OPERATION</h1>
<h1 id="21-overview">2.1 OVERVIEW</h1>
The DMM 8008 can work as a stand alone unit [Stand Alone Mode], where up to 6 preset can be recalled by directly selecting them through the 6 "preset" buttons available on the front panel, or an work as completely remotely controlled unit [Remote Control Mode].
As soon as is turned ON the device will indicate the current Firmware version
DMM 8008

As the picture shows, in the System Setup mode the buttons 1/2/3/4/6 are used as Enter/Down/Up/Esc/Page commands, used for scrolling, accessing and editing the following 5 Menus:
1. Tcp/Ip Setup
2. Output Switch Linked
3. Out Switch Setup
4. ID RS485 Setup
5. USB/RS485 Setup
From the first "Tcp/Ip Setup" Menu, just using the Up/Down buttons, the all other Menus can be accessed.
<h1 id="221-tcp-ip-setup">2.2.1 TCP / IP SETUP</h1>
Within this Menu, the User can set the DMM 8008 IP Address
From the Tcp/Ip Setup, pressing the Button 1 / Enter, the following sub-menu is entered:
<h1 id="tcplp-setup-ip192168000001-2">Tcp/lp Setup IP=192.168.000.001</h1>
Here, the first digit of the IP will be blinking, which means the User can modify the digit's value using the Up/Down buttons.
Once assigned the desired value to the digit, confirm it pressing the Enter button.
After a while, the system will automatically go to the second digit of the IP address, which will start blinking. With the Button Page, a digit can be skipped without being modified, so using Page is possible to scroll into the all 4 digits of the IP Address, without the necessity to modify them.
The first digit of the IP Address can range from 1 to 223, the second and third digits can range from 0 to 255 and the fourth digit from 1 to 255.
The system will automatically compute the right "Sub Net Mask" value to assign to the Unit, once defined the IP address.
The Sub Net Mask values are the following:
1. IP Address from IP=001.0.0.2 up to IP=126.255.255.254, SubNetMask = FF000000h (Class A)
2. IP Address from IP=127.0.0.2 up to IP=191.255.255.254, SubNetMask = FFFF0000h (Class B)
3. IP Address from IP=192.0.0.2 up to IP=223.255.255.254, SubNetMask = FFFFFFF00h (Class C)
Once set properly the IP Address, the Tcp/Ip setup Menu can be left using the Esc button.
<h1 id="222-usb-rs485-setup">2.2.2 USB / RS485 SETUP</h1>
Within this Menu, the User can chose between the USB or RS485 connection type to be used for a remote control.
From the USB/RS485 Setup page
<h1 id="system-setup-usbrs485-setup-2">System Setup ---- USB/RS485 Setup ----</h1>
pressing the Button 1 / Enter, the following sub-menu is entered:
<h1 id="usbrs485-setup-mode-usb-2">USB/RS485 Setup Mode = USB</h1>
Here, the communication interface to be used can be selected: USB/RS485/Automatic.
The Tcp/Ip connection is EVER available.
In the USB mode, the DMM 8008 can be controlled via USB interface or via Tcp/Ip connection.
If selected, the USB interface will be active as default when the DMM 8008 is turned ON.
In the RS485 mode, the DMM 8008 can be controlled via USB interface or via Tcp/Ip connection.
If selected, the RS485 interface will be active as default when the DMM 8008 is turned ON.
If selected the Automatic Mode, the unit will continuously "switch" between USB and RS485 (each about 100ms), looking for an available Remote Control on one of the 2 interfaces.
Once found an available one, the DMM 8008 will communicate vi the interface corresponding to the one found.
If selected, the Automatic interface will be active as default when the DMM 8008 is turned ON.
The currently active connection type, will be displayed on the extreme right of the LCD's top row, with the U/R/A symbols (USB/RS495/Automatic)
<h1 id="223-id-rs485-setup">2.2.3 ID RS485 SETUP</h1>
Within this Menu, the User can define the ID of the DMM 8008 when working with a remote control via RS485 interface.
From the ID RS485 Setup page
System Setup
ID RS485 Setup
pressing the Button 1 / Enter, the following sub-menu is entered:
ID RS485 Setup
ID = 1
Here, the ID number of the DMM 8008 can be assigned.
The possible ID values range from 1 to 64.
The ID number can be selected using the Up/Down buttons.
The Enter button has to be used to SAVE the assigned ID number and exit the Menu.
The Esc button has to be used to exit the Menu WITHOUT SAVING the ID number.
<h1 id="224-output-switch-linked-setup">2.2.4 OUTPUT SWITCH LINKED SETUP</h1>
The DMM 8008 has internally the possibility to store up to 10 Presets "Switch" (Only by Pc Sw) and on each one of these presets is contained the Status of the Output Switch lines (Output Ports S1/S2/S3/S4) available on the DMM 8008 back panel.
These 10 presets can be recalled in LINK with the corresponding "Audio" Preset, by pressing one of the 6 Presets Buttons of the front panel (or just loading the presets by Pc), once the Output Switch Link function is set as ON.
In this case, any time an Audio Preset is recalled by pressing one of the front panel's buttons, the equivalent Switch preset Is also loaded: it the Audio Preset N. 1 is recalled, the Switch preset N. 1 is recalled too. In a such case, each recalled preset is a combination of an Audio and a Switch preset.
To get the above result, need therefore to enter the System Setup's Output Switch Linked page
System Setup
---- Output Switch Linked ----
And to set as On the Link
OUTPUT SWITCH LINKED
Link = ON
If the Output Switch Linked is not active and the Switch presets aren't linked to the Audio ones, they'll not be recalled once pressed any one of the Preset Buttons.
Therefore, the Switch Outputs status can be "manually" defined by the User who will be allowed to recall "manually" one of the 10 Switch preset and leave it active until a new "Manual" setting or a change of the Output Switch Linked Status.
If the Output Switch Linked mode is set with Link = OFF, the User can "Manually" Load one of the 10 switch Presets available and previously created using the Pc Sw.
This can be done from the Out Switch Setup Menu
<h1 id="system-setup-out-switch-setup-2">System Setup ---- Out Switch Setup ----</h1>
Within this Menu, the User can select and Load one of the 10 available Switch Presets.
Pressing the Button 1 / Enter, the following sub-menu is entered:
<h1 id="output-switch-setup-sp01-2">OUTPUT SWITCH SETUP SP01</h1>
Here, the user can recall one of the 10 available Switch Presets SP01-SP10, just selecting the desired one by the Up/Down buttons.
As said, in this way any action on the Preset Buttons, forcing the Load of the corresponding Audio Preset, will not affect the status of the Output Switches, which will depend from the Preset loaded "Manually" by the User within the Output Switch Setup, being the Output Switch Linked Status set as OFF.
In order to finally leave and exit the System Setup mode, so to get back to normal working mode, is is enough to get back to any one of the 5 System Setup Menus and there from press the ESC button.
NOTE: The All Settings done within the System Setup Function will be effective ONLY WHEN LEFT the System Setup Mode itself.
Within the System Setup Mode, the all communications with the remote control units are DISABLED, so as the some "Real Time" processes available in the DMM 8008.
In Stand Alone Mode, the "Activity" of the DMM 8008 in terms of running processes and signal status, per each channel, can be checked thanks to the Vu-Metering features:
1 led for Microphone Phantom Power Supply Active
5 led for Outputs Activities:
<h1 id="23-remote-control-mode">2.3 REMOTE CONTROL MODE</h1>
The DMM 8008 is mainly thought to operate with Remote Control Sw running on Pc.
Nevertheless, once created the desired presets for the defined applications, the unit can operate as a Stand Alone one, as seen before or as Wall Panel Remote Control working device.
The Remote control, when operated by the Wall Panel Remote control, is working on the base of the RS485 connector of the DMM 8008
The Pc Sw remote control, can instead operate with USB, RS485 or Tcp/Ip connection.
When used the USB connection, the Pc Sw Remote Control can control/edit ONLY one unit per time.
When used the RS485 or Tcp/Ip connection, the Pc Sw Remote Control can control/edit MORE units at the same time, connected each others in net.
A particular way of "double" Remote Control is allowed, being possible to connect to the Rs485 the Wall Panel Control and at the same time the Pc Sw Remote Control can be used if connecting the Pc on the USB connection.

When selected microphone as input, the user can chose to select on the input itself a 3bands Eq process on the Input signal, or a Feedback Eliminator.
When the 3 bands Eq is selected, the Equalizer can be edited in the same way shown for the Line Input case.
When the Feedback Eliminator is selected, it can be activated or not, and when active, its deviation can be set. The Feedback Eliminator is working on the base of a frequency shift process avoiding the feedback to raise up. The speed of the feedback elimination process it is just defining the amount of frequency shift is added to the input signal.
Independently from the Input selected (microphone or line), on the Inputs are ever available a first order Low Pass filter and a Noise Gate.
First Order Low Pass Filter: this filter is a first order Low Pas, with a 3dB/Oct Slope.
The filter's cut of frequency is ranging from 20kHz up to 1kHz by steps of 1/3 of Octave.
The filter can be made active or not (bypassed), checking or unchecking the "Enable" check box:
Once active, the smooth first order LP filter is intended to be mainly used with the microphone's input selected, in order to reduce the amount of high frequencies without affecting significantly the voice quality, nevertheless increasing the immunity to the Feedback.
Noise Gate: the particular DMM 8008 Noise Gate can be selected or bypassed checking or unchecking the "Enable" check box:
This Noise Gate has been thought as Noise Gate for the Line inputs, but also as Auto Switch On/Off when operating with the microphone inputs.
From this point of view, the range of a standard Noise gate have been extended, and particularly the one of the Gating Threshold, so to better fit the characteristics of the voice signal

Noise Gate - Inp1

</details>
Gating Threshold: the gating threshold is ranging from -80dB up to 0dBu.
This threshold is allowing to set a gating level for the microphones, pretty high, allowing in this way to open or close at level far from the common noise floor, so to open or close when a hi level signal, as the voice, is detected at the microphone's input or not.
Attack Time: it is ranging from 1ms up to 1 second and represent the speed of the Noise Gate in "closing" the input level once a signal in input is detected to be below the Gating Threshold.
Release Time: t is ranging from 10ms up to 1 second and represent the speed of the Noise Gate in "opening" the input level once a signal in input is detected to be above the Gating Threshold.
A Phantom power supply can be activated if microphones using a such power supply are chosen.
Note: at the bottom of the Meter Bar aside the level slider, both when Line or Microphone Input are selected, there is an indicator indicating in real time and precisely what's the current Input signal level in dBu
Note1: a "Balance" check box is also available.
When a Balanced Input is used, it has to be checked, so to get the proper input level adjustment.
If a Not Balanced Input is used, the box has to be left unchecked and the input level is automatically adjusted at +6dBu.
Note2: In order to help tuning properly the Noise Gate when used as Microphone Input On/Off Switch, 8 Leds indicating the Inputs status is available in the Led meters interface:

The line of "Input Off" leds is indicating when an Input is Off or Muted by the Noise Gate. In that case the related Led is turned RED.
Once set the microphone inputs configurations, if used the Noise Gate as microphone On/Off Switch, the Noise Gate parameters and mainly the Gating Threshold can be tuned checking when the corresponding Input will be muted without any direct source in input but the noise floor.

Step dB - this simple function is allowing to set the resolution in dB of the Grid Lines of the Graphic displaying the Magnitude response of the equalization.
The resolution can be set in a range from 5dB up to 50dB, by steps of 5dB.
Offset dB - here can be set an "offset" in dB in visualizing the Magnitude response of the equalization.
Once added a positive offset, more space is given in the graphic to the visualization above the 0dB, when a negative offset is added, more space is given to the visualization below the 0dB.
The offset can be set in a range from 10dB up to -120dB, by steps of 10dB.
Level [dB] – from this sub-frame it is possible to set the Output Channels Level from -127dB up to +18dB.
Pressing the "Bypass" button at the bottom of the Level slider, the currently set level will be skipped and the output level will be set to 0dB.
Phase - when this check box is "unchecked" the processed signal is left with its original phase.
When the check box is "checked", then the original phase of the signal is inverted of 180Deg.
Delay - from this sub-frame it is possible to set the Output Channels Delay Time from 000.0000mS (0 meters) up to 380.998mS (129.53932 Meters), by steps of 1mS (Adj arrows) or 20.8uS (Fine arrows).
On each Output channel is available a powerful RMS compressor for improving the sound quality, followed by a Peak limiter useful for limiting the output signal before to enter the amplification system.

Within the Overview Page, can be checked the all channels inputs selection (between Microphone and Line), so as any of the available processes can be accessed double clicking on its name in the processes' block diagram. Particularly, in this page is also resumed the current selections operated for the Inputs in terms of available Eq or Feedback Eliminator processes, when Microphone Input is selected.
Here also can be selected the "Unit" for defining the amount of delay available on each output. The Delay can be actually set in "meters" or "milliseconds".
In the Overview Page are also accessible the Editing Pages of the Automixer and Priority Ducker. The DMM 8008 is running 2 Classic Automixer processes, the NOM (Number of Opened Microphones) and the Gain Sharing. These 2 processes are used with microphones in Conference Systems for Voice quality improvement and Feedback effect reduction.
Has to be noticed here that the DMM 8008 can run together with the Classic NOM and Gain Sharing processes, also the First order Low Pass filter and mainly the Frequency shift Feedback Eliminator. This is providing a very strong Anti Feedback characteristic to the unit, which can let the NOM and Gain Sharing processes act mainly in terms of Voice quality and intelligibility improvement.
The Priority Ducker is a process able to assign to up to 4 microphone/line inputs, priority on the others, which will be attenuated in their input level as soon as a signal is detected on one of the input having the Priority. The Priority Ducker is mainly used in Conference System applications, there where is necessary to assign a priority to a microphone used by one Chairman or more equal priorities speakers. Nevertheless, the Priority Ducker can be very useful also in installation systems, there where a microphone or line input is used as Priority channel for priority or urgent announcements.
3.5 AUTOMIXER FUNCTIONS
The DMM 8008 can perform 2 Classic processes of the Automixers, the NOM Attenuation and the Gain Sharing one.
NOM Attenuation : this is a process able to detect the number of microphones active (Opened) at the same time and, on the base of the Number of Opened Microphones, it is applying a predefined amount of attenuation to each microphone's input.
A simple formula determines the NOM Attenuation: "Attenuate by 3dB for every doubling of the Number of Open Microphones", which translates to the following:
NOM Attenuation = 10log(NOM)
Here are some examples to better illustrate the NOM attenuation:
- 1 active microphone means no attenuation: 10(1) = 0dB
- 2 active microphones translates to doubling the NOM: 10 (2) = 3dB of attenuation
Once the limit of 8 active microphones is reached (9dB attenuation), the NOM count and attenuation maximum is reached and will not increase further (hopefully the eight people trying to talk at once will have figured that out by then...).
Here following a table resuming the NOM Attenuation applied on the base of the number of Opened Microphones:
| NOM | Output Gain Adjustment (dB)10log (NOM) |
| 1 | 0 |
| 2 | -3.0 |
| 3 | -4.8 |
| 4 | -6.0 |
| 5 | -7.0 |
| 10 | -10.0 |
| 20 | -13.0 |
| 100 | -20.0 |
Note: The NOM attenuation could be free confidurable.
Gain Sharing: This process is based on a dynamic control of the gain of each microphone channel; the gain of each channel is adjusted by comparing its level to the level of the sum of the level of the all microphones.
The gain is computed so that the combined system gain of all microphones remains constant.
In this way, the microphones with the strongest signal are given the highest gain and those with low level signals have their gain reduced.
Specifically, each microphone channel is attenuated (turned down) by the amount, in dB, equal to the difference between that microphone channel's level and the sum of all microphone channel levels.
In example, if two talkers are each speaking on their own microphone channel at the same level, then the level of the sum of all channels would be 3 dB higher than the level from each of these mics (power addition).
Each microphone would then be turned down 3 dB.
If a person is being picked up equally by two microphones, the sum of these two signals would increase 6 dB. (The 6 dB increase results from the addition of two coherent signals.)
The level in each mic channel would be 6 dB lower than the sum and the gain of each mic is reduced 6 dB.
The resulting output would be the same as if only one mic were on. In a final example, a talker is speaking into his mic, but his voice also enters an adjacent microphone at a level 4 dB lower.
In a gated system, this second mic could very easily be gated "on" creating comb filtering effects.
In the gain sharing system, the gain of the second mic will be attenuated 4 dB.
This makes the level from the second mic 8 dB lower than the first, which will greatly reduce the interference. As said, the DMM 8008 can perform both processes.
The user can select which one to make active, entering the Automixer editing page and selecting the desired process, checking the related check box.
![Automixer AutoMixer Active Mode NOM Gain Sharing Gain Sharing Level [dBu] 0](/content/2026/05/956652/images/a507e92b552da6b62f554553a7e60591d7bd88aebce7ac19ae168514f9e34487.jpg)
If selected the Gain Sharing option, the Max Gain available to the SUM of the all microphones can even be set using the Gain Sharing level Slider.
When the Slider is set on 0dB, the MAX output available (virtually 0dB) is available to the SUM of the all microphones level.
If the slider is set at a different value, as in example -6dB, the Max gain allowed to the SUM of the all microphones level is -6dB.
This means that respect the case of the slider set to 0dB, the Gain of the microphones will start to be adjusted 6dB earlier when the slider is set to -6dB.
3.6 PRIORITY DUCKER
The Priority Ducker is a Side-Chain dynamic process, used to attenuate the level of a certain number of input channels on the base of a signal detected on an independent input.
In our case, the Priority Ducker Process is allowing to select from 1 to 4 Inputs as inputs having priority on the other ones.
When signal above a defined threshold is detected on one of the Priority Inputs, the all others are attenuated of a defined amount of dB.
The Priority Ducker implemented on the DMM 8008 is allowing to assign to up to 4 of the all available Microphone/Line Inputs, Priority on the others.
Particularly, when a signal above the Gating threshold is detected on one of the Priority Inputs, the other inputs are attenuated of the Attenuation Level.
The Attenuation action is taken with the Attack Time speed and is maintained for the Hold time, after the signal on the Priority channels dropped below the Gating Threshold, before to go back to the original level in a time defined by the release time.
The all parameters of the DMM 8008 Ducker, can be set within the Ducker Edit Parameters window
![Ducker edit parameters Priority Input Channel ✓ 1 ✓ 2 ✓ 3 ✓ 4 ✓ 5 ✓ 6 ✓ 7 ✓ 8 Contim Parameters 30 11 3 -40 -74 Hold Time [ms] Release Time [ms] Attack Time [ms] Gating Thr [dB] Attenuation Level [dB]](/content/2026/05/956652/images/ae132efd3f690a1d4ce03bbf52d79ca8e3d4821e905f5f6750cfab61c87bfe2a.jpg)
Here can be defined the following
Priority Input Channel: up to 4 check boxes can be checked for choosing up to 4 channels which will have priority on the unchecked ones.
Once selected the Priority Channels, in order to make the Priority effective, need to confirm the selection pressing the "Confirm" button.
Gating Threshold: it is the threshold defining the limit has to be passed by the input signal level on the Priority channels to activate the ducking process and it is ranging from -44dB up to 0dB.
Attenuation Level: it is amount of attenuation applied to the channels not having priority when the Ducking process is active and is ranging from 0dB up to -80dB.
Attack Time: it is the speed needed by the Ducking process to reach the set Attenuation Level once the Ducking process is activated and is ranging from 1ms up to 2 seconds.
Hold Time: it is the time in between the de-activation of the Ducking process and the Release action and is ranging from 10ms up to 1 second
Release Time: it is the speed needed by the Ducking process to get back to the original gain level of the channels not having Priority, once the Ducking process is de-activated and is ranging from 1ms up to 2 seconds.
3.7 BACKGROUND UTILITIES
In this background screen, ever present together with the other editing pages, is displayed the channels' status.
Here are mainly reported the all activities of the DMM 8008 front panel's leds.
Each Input/Output channel can be muted so as input channels and output channels can be "linked" together so to report on the all linked channels the same parameters adjustments.
To link 2 or more channels, it is enough to press the related buttons within the "Input Linked" and "Output Linked" frames.
The Main output Level can also be adjusted from this Utilities window.
![Master Output Volume [ dB ] ---------------- 0 Setup USB/RS485](/content/2026/05/956652/images/a5b456595315b3f15c238c4087b4b09812f2ea3d870c7e26d5e3bb102335f1bd.jpg)
This is the same Level control used by the Wall Panel Remote Control.
Through the "Setup" button a selection window can be accessed allowing to set the DMM 8008 in Manual Mode, choosing the USB or RS485 interface, or in Automatic mode.
From the Utilities Window, can be accessed also the all processes for Saving/Recalling presets to/from Pc and to/From the DMM 8008 and for configuring Special Processes activated by the External Switch Input Ports.
Particularly:
Load: allows to load on the Pc Remote Control a configuration previously saved on Pc
Save: allows to save on Pc the current editing session
Store: allows to store on the DMM 8008, in one of the 6 available location, the current editing session
Read: allows to read from the DMM 8008, one of the 6 stored presets and to display it on the current editing session
Input Copy: allows to copy the setting of one Input channel on an other one
Output Copy: allows to copy the setting of one Output channel on an other one
Switch: this particular button is allowing to enter e window where from up 4 lines (switches) can be set as 0 (boxes unchecked) or 5V (boxes checked).
The switches controlled by this window actually set as 0V or 5V the physical 4 output "switch" lines available on the DMM 8008 back panel and useful for controlling remote devices.
From this editing window, up to 10 different presets can be created, where a specific Switches configuration is assigned.
In order to create the presets, need first to press one of the 10 "Switch Preset" buttons
Once the specific button is presses, to that button will be assigned the current status of the 4 S1/S2/S3/S4 switches.
To any button, a different S(x) configuration can be assigned.
The different configuration will be maintained until the Pc Sw is open.
On the Pc can be saved ONLY a Configuration a time, the Pc will not store the configurations of the 10 buttons.
Therefore, on Pc will be saved any time the current configuration of the Switches S1/S2/S3/S4.
The several configurations can be then recalled and they'll be assigned to the currently pressed "Switch Preset" button.
In example, creating the following configuration
S1 = checked
S2 = unchecked
S3 = unchecked
S4 = unchecked
The configuration can be saved on Pc as "S1_On".
If recalled, when the Switch Preset button ONE is pressed, then to the Switch Preset Button 1 will be associated with the above configuration of the switches.
Different S(x) configurations can be saved with different names and be associated to different Switch Preset buttons.
Once assigned different S(x) configurations to different Switch Preset buttons, the user can recall the several configurations from Pc Sw just pressing the several Switch Preset buttons.
In order to store the 10 Preset configurations within the DMM 8008, so to be able to recall them by DMM 8008 front panel or together with the "Audio Presets" if active the "link" function (see later), it is enough to press any Switch Preset button in order to make it active and press the "Store to Device" button.
The preset related to the currently active Switch Preset button, will be stored in the equivalent preset location within the DMM 8008.
In order to store the all 10 presets, need to make active one by one the all Switch Preset buttons and for anyone of them press the "Store to Device" button.
Once stored within the DMM 8008, the 10 presets controlling the S(x) switches status can be recalled manually and independently from the "Audio" Presets, from the unit's front panel.
If the User want to recall the Switch Presets together with the Audio Presets, which would mean that together with the Audio preset number 1, the user want to be recalled also the Switch Preset number 1 (the Audio preset and Switch Preset numbers have to match...), then is necessary to LINK the Audio Presets and the Switch Presets.
This can be done checking the "Link Switch preset to Audio preset" check box within the Link Switch frame of the Switch Editing window.
To the Switches can also be assigned a NAME, just pressing the "Edit Switch Name" button and entering the Edit Switch Name window
Extra Program: the External Program section is allowing the user to set as active or not active anyone of the 4 available Input Switches.
When set as active one or more of them, it is also possible to define with the "Configure Mode" option, if the Input Switch signal has to be considered active on its High or Low level detected.
Furthermore, it is also possible, in case more Events related to the Input Switches are occurring at the same time, so activating at the same time more than one Switch, to assign a Priority in "serving" the events related to the active Switches (see below).
The desired Priority can be set selecting one of the 8 options available, corresponding to the following Priority Table (accessible pressing the "?" button aside the "Configure Priority" selection box):
| Priority | With mode - Signal Active High | With mode - Signal Active Low |
| 0 | recall program E4 if S4 = 1 orrecall program E3 if S3 = 1 orrecall program E2 if S2 = 1 orrecall program E1 if S1 = 1 | recall program E4 if S4 = 0 orrecall program E3 if S3 = 0 orrecall program E2 if S2 = 0 orrecall program E1 if S1 = 0 |

| S1-S4 refer to the respective contacts of the Input Port terminal | ||
Once operated the all desired selections, need to "Confirm" them before to exit the "Configure External Signal" Page.
To anyone of the 4 External Switches (Events) can be related a specific process.
This process is corresponding to a Input/Output specific Configuration (Preset), that has to be recalled ONLY if the related Event (Switch Active) is occurring.
So, 4 Extra Presets other than the 6 available for the normal operations, can be created and stored, so to be recalled ONLY when the related event is occurring.
Once create the 4 Extra Presets, they can be stored within the DMM 8008 Through the Button "Store":
![Store Program Extra Memory Programs Extra 11 02 03 04 Edit Name [max size 16 characters] Program Empty Select position 1 Cancel Store](/content/2026/05/956652/images/9a533af3d7834da276901a027a002d3bc5e3a9f978f05e6feb753640be5ffc7c.jpg)
The Extra Presets can be saved in 4 available locations where the location number is corresponding to the related Switch Input Event.
To anyone of the 4 Extra Preset can be assigned a specific name.
Once saved the Extra Presets, they can be anytime recalled for check using the "Read" button.
For Leaving the Remote control Sw, it is enough to click "Exit" on the "file" option on the top left corner of the Main Editing Environment.
Once left the Pc Sw Remote Control, the DMM 8008 will go back to the Stand Alone Mode and the LCD will display the currently running preset:
