A. The Mic Amp Module A.1 Connection The rear panel of the module carries the Mic (‘IN’) and Line input (‘LINE’) XLRs along with a single output (‘OUT’) XLR. The Line input and output operate at a nominal level of +4dBu although the gain of the Line input can be varied by a front panel control.

X-Rack Owner’s Manual A.2.3 HF/LF Section This section contains simple high and low pass filters as follows: HF (Low Pass): LF (High Pass): The two filters can be switched into circuit independently. A.2.4 OUTPUT Section This small section contains a tri-colour signal present indicator and two routing switches (‘REC L’...
The following pages contain audio performance specification figures for the X-Rack Mic Amp module. No other Solid State Logic products are covered by this document and the performance of other Solid State Logic products can not be inferred from the data contained herein.

X-Rack Owner’s Manual A.3.4 Instrument Input Performance Un-balanced signal applied to Instrument Input and measured at Output. Pad switched out and Input Gain control set to +12dB (minimum). Gain Input Impedance Output Headroom THD + Noise (-18dBu applied, +28dB gain) Frequency Response Equivalent Input Noise (Input terminated with 150Ω)
A.4 Calibration Information The X-Rack Mic Amp module is factory calibrated and should only need calibration if a potentiometer or other component has been replaced or if it is suspected that there is a problem with calibration. In each of the following instructions it is assumed that the lid of the X-Rack has been removed and that power has been applied.

The EQ Module B.1 Connection The module input and output gains can be set to operate at a nominal level of either +4dBu or –10dBV, using a switch on the connector panel. To select the appropriate level for the equipment you are connecting to, please check the operating manual for your mixer or DAW.

D. The Dynamics Module D.1 Connection The module input and output gains can be set to operate at a nominal level of either +4dBu or –10dBV, using a switch on the connector panel. Select the appropriate level for the equipment you are connecting to. If in doubt experiment! To check the input and output gains, set the compressor Ratio and Threshold controls -10dBV fully clockwise and send a signal close to the nominal operating level of your mixer or...

X-Rack Owner’s Manual FST ATK – Normally, a controlled linear attack time of 1.5ms per 40dB is provided. Press this button to select a fast attack time (100µs per 40dB). The attack time is the time taken for the Gate/Expander to ‘recover’ once the signal level is above the threshold.
