[. . . ] You can, for example, intensify the control function in a specific frequency range by inserting an equalizer via the SC SEND AND SC RETURN jacks. Detailed information on this special application can be found in chapter 3 EXAMPLES OF SIDECHAIN APPLICATIONS. This function, too, is only available on the AUTOCOM PRO-XL and COMPOSER PRO-XL. The SC MON switch links the sidechain input signal to the audio output, thereby muting the audio input signal. For example, this allows you to pre-monitor the sidechain signal in combination with an equalizer or other device inserted into the sidechain channel. The SC MONITOR function makes it easier to for example adapt the equalizer filters to the control signal. With the SC MONITOR switch activated, only the sidechain signal will be present at the output, which is shown by the flashing LED switch!The OUTPUT control allows you to raise or lower the output signal by max. 20 dB, so as to make up for a gain loss caused by the compressor or limiter action. Raise the gain by roughly the same amount that it has been reduced by the compressor. When you adjust the LIMITER control in the peak limiter section, please note that the output gain of the compressor is set before the peak limiter. If the level is too high here, the peak limiter may respond permanently (see LIMITER control in the peak limiter section). The 12-digit INPUT/OUTPUT LEVEL display (MDX4600: 8-digit) reads both the level of the incoming audio signal and the level at the dynamics processor output. The IN/OUT METER switch selects whether the gain LEDs read the input signal (switch pressed) or the output signal (switch not pressed). This display is referenced to the operating level selected with the OPERATING LEVEL switch on the rear of the unit (-10 dBV or +4 dBu). if it is OUT or the unit is not connected to the mains, the input jack will be linked directly to the output jack (COMPOSER PRO-XL MDX2600 only). Usually, this switch is used for direct A/B comparison between unprocessed and compressed/limited signals. + + + 6 2. CONTROL ELEMENTS AND CONNECTORS AUTOCOM PRO-XL MDX1600/COMPOSER PRO-XL MDX2600/MULTICOM PRO-XL MDX4600 Application hints Setting the compressor will be much easier if you first set both limiter and expander to a neutral setting by turning both threshold controls (TRIGGER and LIMITER) to OFF. Setting the compression ratio requires your sense of hearing: Anything goes. In general, however, the ratio setting should not be too high for mix signals; instead, use 2:1 as a starting point to preserve the natural sound of the music; a ratio setting of about 4:1 has proved successful for vocal recordings. The IKA (Interactive Knee Adaptation) characteristic allows you to achieve a gradual and inaudible compression and hence to use higher ratios. If you want to use the compressor as an effect in its own right, dont hesitate to experiment with higher values.
