xpressor 500

Controls

Threshold (Thresh): The operating point of the compressor. If the input level exceeds the value set with this controller, the compression process will start.

Attack: The transient response of the compressor. It determines the time the xpressor 500 needs to reach 10 dB of gain reduction.

Release: The return phase of the compressor. It controls the period of time between the input signal falling below the threshold and the xpressor 500’s return to unity gain.

Ratio: The relation between the input level and the output level. As a specialty of the xpressor 500, even negative ratios can be set here. (p. 10)

Sidechain Filter (SCF): A tunable low cut filter in the sidechain of the xpressor 500 avoids overcompression and pumping when there is a lot of low end energy in the mix.

Gain Reduction Limiter (GRL): Restricts the control voltage. This innovative limiter is not placed in the audio path as usual, but in the control circuit of the compressor. (p. 11)

Gain: The make-up gain of the xpressor 500. This controller compensates for the loss in gain caused by the compression process.

Mix: The direct and the compressed signal can be blended in any desired relation by simply turning the mix controller.

Onboard parallel compression!

Gain Reduction Meter: The display for the gain reduction process. Shows the amount of compression measured in dB as an visual support for the acoustic events.

GRL LED: indicates Gain Reduction Limiter activity. If this

LED is on, incoming signals will be held at the GR limit instead of being compressed any further. (p. 11)

Auto Fast: A semi-automation. This function shortens the attack time automatically on fast and loud signal impulses and then returns to the value set with the controller. (p. 7)

Log Release (Log Rel): This alternative release curve follows a logarithmic course instead of the standard linear progress which results in a very gentle kind of compression. (p. 8)

Warm Mode: The xpressor 500 offers a second switchable sound flavor by altering its frequency spectrum, harmonics and transient response. (p. 9)

Hit It! Activates the xpressor 500 (LED on) or deactivates it with a hardwire bypass (GR meter remains active).
