Controls

Byp

(bypass)

When activated, routes the input signal directly to the output channel without passing through the Compressor Limiter. The Side Chain input is not bypassed, so the threshold indicators and gain reduction meters continue to update.

Thresh

(threshold level)

Sets the input level above which the compressor will attenuate the input signal. If the level of the signal at the Side Chain input is lower than the Threshold Setting, the compressor routes the signal through the device unaffected (unless a Soft Knee value has been specified).

Ratio

(compression ratio)

Adjusts the severity of gain reduction produced by the compressor once the input signal has exceeded the Threshold Level. Dynamic variations in the input signal will be reduced by a factor equal to the compression ratio.

Max Atten

(maximum attenuation)

Sets the maximum amount of attenuation to be applied to the output signal.

Signal

Above

Lit when the input signal level exceeds the Threshold level.

Knee

Lit when the input signal level exceeds the Soft Knee level.

Below

Lit when the input signal is below the Soft Knee level.

Note: These indicators sample the actual input signal, before the expander's response.

Attack time

Sets how quickly the compressor reacts to an increasing input signal.

Release Time

Sets how long the compressor waits before releasing its attenuation value.

Gain Reduction Meter

Indicates the amount of attenuation currently being produced by the compressor.

Note: The compressor is capable of unlimited attenuation. However, the meter is limited to -35dB.

Soft Knee

Sets a second threshold level, which attenuates the incoming signal at a reduced compression ratio before it reaches the Threshold level.

Make Up Gain

Increases or decreases the signal level.
