XLogic Multichannel Compressor Owner’s Manual
3.0Installation
3.1Voltage Selection
Before connecting the mains supply ensure that the voltage range selector next to the IEC socket on the rear of the unit is correctly set. The input setting must be confirmed before applying power. The input module can
be configured to be one of 4 voltage settings. The setting is indicated by a plastic pin protruding through the
appropriate hole in the fuse panel - the example shown here is set for 240V operation.
100V
120V
2 3 0V
2 4 0V
The setting is altered by a small vertical PCB which can be fitted in 4 positions. To change the setting:
•Switch off and remove the IEC lead.
•Using a small
•At the right hand side is a vertical PCB with a plastic key which indicates the setting. Using pliers, pull out the PCB.
•The PCB has to be rotated until the desired voltage is shown along the edge which plugs into the module. The plastic key (and this bit is quite fiddly) must also be rotated so that it points out of the module so that the round pin aligns with the appropriate hole in the cover panel; (refer to the adjacent illustrations).

Note. Where the mains voltage is a nominal 230V, the ‘240V Setting’ should be used – not the ‘230V Setting’!

3.2Mounting
The XLogic unit is designed to be rack mounted. It is 2 RU (89mm/3.5 inches) high. Its depth is:
325 mm/12.8 inches not including heatsink
365 mm/14.3 inches including heatsink
400 mm/15.75 inches including connectors
The unit must be mounted on suitable rack shelves: do not rely on the rack mounting ears alone.
A 1RU space should be left above each unit to ensure adequate ventilation.
3.3Connection
The unit has six input XLRs (female) and six output XLRs (male). Connect the inputs to the main output insert sends of your console or to your workstation outputs. Connect the outputs to the corresponding insert returns or to your workstation inputs.
When the unit is switched off the input XLRs are linked to the output XLRs by relays, so the unit will pass signal even when switched off. There is a 3 second delay after switching on before the bypass relays are energised to allow the power rails to settle, thus avoiding unpleasant thumps and pops on your monitoring.
Note that when switched off the DC coupled input stage of the XLogic Multichannel Compressor can load the output stages of some devices, causing low level distortion. For this reason it is not advisable to leave the unit connected and switched off.
Once the unit is connected switch it on, then route signal to each channel in turn and check that the correct signal LED lights yellow in the MAX display and that the signal is returned to the correct input on your console or workstation.
