- Page 4 Dear friend of audio culture, First of all, we would like to thank you sincerely for choosing the mpressor as your new compres- sion tool. We believe this is a true step forward. Instead of a further copy of concepts that were invented several decades ago, you now have an absolutely contemporary tool for processing dynamics at your disposal.

Page 6: Basics
BASICS Controls Both channels of the mpressor are absolutely identical regarding their electronic design. Therefore both sides of the front panel have exactly the same controls and switches. Continuative informa- tion on the specific functions can be found on the pages in brackets. Threshold Attack Release... -

EQ Freq: the center frequency of the Niveau Filter. Around this reference point, bass is boosted and treble is cut or vice versa. (pp. 11, 21) x10: shifts the frequency range of the Niveau Filter. The printed values from 26 Hz to 2.2 kHz are multiplied by 10 to 260 Hz and 22 kHz. -
Page 8: Connectors
BASICS Connectors Please pay attention to operate the mpressor with the correct voltage setting for your country and the proper pin assignments on the XLR connectors. Mains module This module combines the line cord connector, the on/off switch, the fuse holder with in- tegrated 230/115 VAC voltage selector and a line filter for providing the transformer with clean current. -

Page 10: Auto Fast
BASICS Auto Fast The attack time parameter is a very crucial factor for the control behavior of a compressor. There- fore choosing the right setting is very important, but depending on the dynamic progress of the source material this can be a difficult task – no matter if you are processing single channels or complete mixes. -
Page 11: Gain Reduction Limiter
Gain Reduction Limiter A specialty of the mpressor is the Gain Reduction Limiter for the control voltage of the compressor. This limiter is not placed in the audio path where you would usually find it, but in the control path of the compressor. -

Page 18: Reference
REFERENCE THD Analysis This diagram shows the FFT spectrum with a sine wave of 1 kHz at 0 dBu. The additionally gener- ated second and third harmonics at 2 kHz and 3 kHz which make the processed signals sound richer and more interesting become very obvious here. These harmonics are generated in the transconductance amplifier stages of the mpressor. -
Page 19: Attack
Attack Here we see how a burst signal (a sine wave which is boosted by 20 dB for a period of 400 ms in this case) is used to demonstrate the effectiveness of the attack controller. The different curves show how fast the jump in level is reduced by 10 dB. -
Page 20: Release
REFERENCE Release This figure is based on a very fast attack time which produces -6 dB of gain reduction. The burst lasts for 50 ms and then follows the release phase with its time parameter set to different lengths. The linear characteristic of the release curve is easy to see here. Arising from the circuit used for this process, the attack time has to be added to the release time. -
Page 21: Ratio
Ratio The mpressor is a typical hard knee compressor, which can be seen in this diagram very obviously. Compression directly starts with the full adjusted ratio in the very moment the input signal passes the threshold point. Compared to a soft knee characteristic, this kind of compression is more on the noticeable and audible side. -
Page 22: Eq Gain Low
REFERENCE EQ Gain Low This measurement shows different settings of the EQ gain controller between middle and fully counter-clockwise position at a center frequency of 1.5 kHz. The diagram shows the effectiveness of the filter: The lower frequencies are boosted up to 6 dB, then the curve crosses zero at the center frequency. -
Page 23: Gr Limit Envelope
GR Limit Envelope Here, a burst signal is used to demonstrate the effect of the Gain Reduction Limiter. While the lowest curve represents the maximum amount of gain reduction in this example, the other curves show the reduction that is influenced by different settings of the now activated limiter. The effect of this function can also be observed with a look at the gain reduction LED meter: The displayed value never exceeds the limit which is set with the GR Limit controller –... -
