Mapping

A maximum of 16 channels can be selected from any input or zone. That is, an already mixed zone can be part of another mix too. A zone can be mapped into all output channels.
Note: Test, Talk Over and Priority sources do not need to be mapped to the corresponding zone’s mixer. Those sources are picked up once they are assigned within that DSP feature.


Note: If a mapped input or zone is removed from the list in a zone, a blank box is left there. You may remove the blank box by clicking on the bin icon again. This removal will shift the mixer levels to the channels that come after. In other words, mixer settings stay constant but mapped channels shift upwards.

Pre-Gain, Gain & Automatic Gain Control (AGC)

Pre-Gain

Manually adjustable pre-gain for microphone/line level adjustment is available for input signals up to 22dBV/24dBu. It is a digitally controlled analogue gain stage. Pre-Gain can be used with both Gain and AGC.

Parameter Name

Parameter Range

Parameter Definition

Pre-Gain

-6/0/34/40 dB

The Pre-Gain parameter offers a selection of four gain levels for the microphone level, line level, and hot signal source (e.g., DJ setup).

Gain

Gain is available for all input channels with a range of -35 and 35 dB. It is also possible to adjust the input gain automatically.

Parameter Name

Parameter Range

Parameter Definition

Gain

+/-35 dB

Input signal up to 22dBV/24dBu

Automatic Gain Control (AGC)

All inputs contain the possibility to enable Automatic Gain Control (AGC). This continuously adjusts the input gain, ensuring a constant output level while the input level varies. The gain adjustments are made in extremely small step adjustable sizes ensuring high-quality audio, even during gain changes.

Parameter Name

Parameter Range

Parameter Definition

Target (A)

-20 - 6 dB

The Target parameter specifies a signal's target level before entering the Matrix. Continuously, the signal matching the level specified by the target parameter will be attempted to adjust.

Max Gain (B)

0 - 30 dB

The Max Gain parameter specifies the maximum gain adjustment which can be achieved between the input level and the target level. This can be used to prevent excessive noise or microphone feedback when, for example, a microphone is not being used. Note that this setting may prevent the AGC from reaching the target level, but this behavior is desirable to achieve the best overall sound.

Hold (C)

0.1 - 60 second

The Hold parameter specifies the AGC hold time during which no action will be taken when the output level falls below the target output level. This is used to prevent the gain from modulating on low frequencies which may cause distortion. For line signals, it is recommended to specify a long hold time to prevent the AGC from adjusting the volume during quiet music passages.

Decay (D)

5 - 200 dB/sec

 

The Decay parameter specifies the time the AGC will take to increase the gain, raising the signal from the current level (below the target level) to the target level. A slow Decay setting can be used if a fixed output level should be maintained, while a fast Decay setting can be used to compress the dynamic range of speech.

Attack (E)

5 - 200 dB/sec

The Attack parameter specifies the reaction time in which the AGC starts attenuating after a sudden increase in input level above the target level. The attack time should be fast to avoid any distortion caused by clipping, but when the attack time is too fast, the AGC will overreact to short peaks, causing audible distortion.

Threshold (B)

-90 - 30 dB

The Threshold parameter specifies the level at which the noise gate will be enabled. When the level of the applied input signal is below the set threshold level, the noise gate will be enabled. This will cut off the signal, resulting in no noise on the outputs. To avoid unwanted noises (noise gate opening and closing rapidly) when the signal level is close to the threshold level, the noise gate function uses a time-out period in combination with hysteresis.

Gain Freeze

Selection

The Gain Freeze will freeze the reached gain level and keeps it fixed.

Gain Recovery

Selection

The Gain Recovery will recover the reached gain level back to 0dB.

LP/HP filter (Input Filter & Output Filter)

2 bands of semi-parametric 2nd order high pass and low pass filters are available on each input channel and can be individually enabled and disabled. Frequency and Q-factor can be adjusted, and channels can be enabled individually. With cascading or combining the available filters, bandpass or 4th order high pass or low pass filters can be created.

  2. Create an event in the Event Handler that uses an alarm system as a GPIO trigger.
  3. The created event should trigger the previously created voice file event.
  4. In the Priority section of the zone, select OS1, OS2 or Mono OS 1+2 as your trigger and input. If you select Mono OS1+2, that channel should be enabled.
  5. The voice file event will be played in that zone as a priority whether it is assigned or not to the zone's Voice File section.

Compressor

A compressor/limiter is an automated volume control tool with the setting of maximum volume to avoid any clipping caused by the signal dynamics or peaks. Threshold and ratio indicate how much the signal is going to be attenuated.

Parameter Name

Parameter Range

Parameter Definition

Enabled

Enable/Disable

Enables or disables the DSP feature.

Threshold

-60 – 6 dB

The threshold control sets the level at which the compression effect is engaged. It will be compressed only when a level passes above the threshold. If the threshold level is set at say -10 dB, only signal peaks that extend above that level will be compressed.
The rest of the time, no compression will be taking place.

Knee

0 -20 dB

The knee is assigned as a numerical value yet can be described as qualitatively: soft, hard, or somewhere in between. The hard knee curve shows a sudden change in slope (ratio) that begins at the threshold. The soft knee curve, in contrast, shows a more gradual change.

Ratio

1-100 (n:1)

Specifies the amount of attenuation applied to the signal. A ratio of 1:1 (one to one) is the lowest and it represents unity gain, or in other words, no attenuation.
These compression ratios are expressed in decibels so that a ratio of 2:1 indicates that a signal exceeding the threshold by 2 dB will be attenuated down to 1 dB above the threshold. A ratio of around 3:1 is considered moderate compression, 5:1 would be medium compression, 8:1 starts getting into strong compression and 20:1 thru infinity to one would be considered limiting by most and can be used to ensure that a signal does not exceed the amplitude of the threshold.

Release Time

0 – 1000 second

It is the time it takes for the signal to go from the compressed "or attenuated" state back to the original non-compressed signal. Release times will be longer than attack times, ranging anywhere from 40-60 ms to 2-5 seconds, depending on which unit you are working with. Typically, release time should be set as short as possible without producing a "pumping" effect, which is caused by cyclic activation and deactivation of compression.
