Precautions WARNING: High Voltage • • • • • • • • • • Risk of electric shock. Do not open chassis. Refer service to qualified service staff only. Before connecting the device to the main power supply, check if the right voltage is selected. Replace fuse with the same type and value only. This device must be connected to ground. Do not use a damaged power cord. Never place containers with liquid, e.g. beverages or a vase, on the unit. Do not expose this device to rain or moisture.
Welcome to Compressor Wonderland! First of all, we would like to thank you for picking the xpressor as your new dynamics tool – a very good choice indeed. This extremely versatile stereo compressor will make your day in terms of dynamics time and again. With its many unique features taken from our flagship products, you not only get great compression, but an amount of control on processing which has yet to be experienced elsewhere.

Auto Fast The attack parameter is a crucial factor for the operation of a compressor. Choosing the right time setting is very important, but depending on the dynamic progress of the source material this is a difficult task – no matter if single tracks or complete mixes are processed. If a very short attack time is chosen, the compressor is able to catch the short peaks, but on the other hand the sustaining signal will also be processed, which might result in audible distortion.
Log Release It is the time constants and especially the release parameter that decide if the processing of a compressor is obvious or unobtrusive to the ear. As it is difficult to achieve perfect results for all kinds of different material with only one type of release curve, the xpressor offers two different options to choose from: logarithmic and linear. It is characteristic of a logarithmic release that the time constant shortens when the amount of gain reduction increases.
Warm Mode This function is basically a slew rate limiter that reduces the speed of the output amplifier stages. This affects the frequency spectrum, the harmonics and the transient response at the same time. Fast transients are slowed down a bit and the overall sound appears more round and merged. As this function influences the behavior of the output stages, the effect it creates has an impact on the complete processing results of the compressor.
Negative Ratios Negative ratios – what exactly does this mean? To get a better understanding of this function, it makes sense to realize what the ratio control of a ‘normal’ compressor does: • 1:1 The signal remains linear, there is no compression process going on. • 1:2 After crossing the threshold, an increase of 2 dB at the input will be compressed to an increase of 1 dB at the output.
Gain Reduction Limiter A specialty of the xpressor is the Gain Reduction Limiter for the control voltage. This limiter is not placed in the audio path where you would usually find it, but in the control path of the compressor instead. When activated, it limits the control voltage according to the setting of the GR Limit controller. This means: No matter how high the input level might become – the amount of gain reduction will never exceed the value you have set.
External Sidechain The external sidechain enables the compressor to control its processing totally independent from the audio material running through it. If an additional audio source is connected to the external sidechain input of the xpressor, compression will not be triggered by the signals from the regular audio inputs anymore, but by a different signal which is fed into the sidechain input.
