Controls

Threshold Level

Sets the input level that determines whether the expander attenuates or amplifies the signal.

An input signal below the threshold will be attenuated

An Input signal above the threshold will be amplified.

Ratio

Sets the attenuation ratio to be applied to input signals below the threshold, up to the maximum attenuation. For example, if the input signal is at -20B, a ratio of two will result in the signal being attenuated to -40.

Maximum Attenuation

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

Attack Time

Sets how quickly the expander reacts to an increasing input signal level.

Release Time

Sets how the long expander reacts to an increasing input signal level

Soft Knee

Sets a second threshold level, which attenuates incoming signals below the threshold value at a reduced compression ratio before it reach the Threshold level.

Note: The soft knee features is most useful with a high Ratio setting, as the amplification effect is less noticeable when the expansion ratio is higher.

Signal

These LEDs indicate:

Above: When the input signal level exceeds the Threshold level.

Knee: When the input signal level exceeds the Soft Knee level.

Below: When the input signal is below the Soft Knee level.

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

Gain Reduction Meter

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

Note: the compressor is capable of unlimited attenuation, however the meters limit is -35dB.

Bypass

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

Response

Expander output level.
