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).

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.

Peaking

Selection

Peaking Filter provides a boost or a cut to a band of frequencies around a center frequency.

Low Pass

Selection

Applies Second Order Low Pass filter. With a Low-Pass filter, the frequencies above the crossover frequency will be suppressed.

High Pass

Selection

Applies Second Order High Pass filter. With a High-Pass filter, the frequencies below the crossover frequency will be suppressed.

Linkwitz

Selection

Linkwitz Transform changes effective frequency and Q-factor to desired values. Typically, this is used to lower F to get more low bass output or to lower the Q to make the box behave like a larger box.

All Pass

Selection

All-pass filter passes all frequencies equally in gain but changes the phase relationship among various frequencies.

Low Shelf

Selection

Low Shelf filter boosts or reduces the audio level below the desired frequency rather than removing them.

High Shelf

Selection

High Shelf filter boosts or reduces the audio level above the desired frequency rather than removing them.

First Order Low Pass

Selection

Applies First Order Low Pass filter. With a Low-Pass filter, the frequencies above the crossover frequency will be suppressed.

First Order High Pass

Selection

Applies First Order High Pass filter. With a High-Pass filter, the frequencies below the crossover frequency will be suppressed.

Frequency

20Hz -20kHz

The Frequency parameter indicates the center frequency of the filter. This is the central frequency between the upper and lower cutoff frequencies of the filter. The frequency can be set between 20Hz and 20kHz.

Q-factor

0.01 - 15

The Q-factor parameter is the quality factor related to the bandwidth of the filter. A higher Q-factor indicates a more selective filter with a smaller bandwidth. The standard Q-factor value for the 7-band EQ is set to 0.9, whereby the 7 bands have good coverage over the entire audio spectrum. A higher Q-factor makes it possible to influence specific frequency ranges of the audio spectrum.

Boost

-15 – 15 dB

The Boost boosts or cuts the desired filter by 15 dB.

Enabled

Enable/Disable

Enables or disables the desired filter.

Channel Volume Slider

-90 – 0 dB

The channel volume slider sets the mix level of the mapped source.

Route

Enable/Disable

The attenuation value of the source selected with the route becomes 0dB, and the attenuation value of the other mapped sources decreases to -90dB or in other words muted.

Scene

Apply/Save

Up to 8 mixing scenes can be saved and recalled.

Master Volume Slider

-90 – 0 dB

The master volume slider sets the mixer or zone output level. In the zone block, the master volume slider and volume settings are identical.

Master Mute

Enable/Disable

The master mute mutes the mixer or the zone output.
