Unpacking:

 

 
Please inspect the unit carefully to ensure that damage had not occurred during

 

 

 

 

 

 

 

 

 

 

 

 

 

shipping. 
Report any damage immediately to the factory, note if there is any obvious damage to

 

 

 

   

 

 

   

   

 

 

   

the packaging. 
 
The unit is supplied with a full complement of Phoenix

3pin pluggable connectors

 

   

 

   

 

   

 

 

 

 

 

installed in their mating sockets. DB multi­pin type connectors and BNC connectors are

   

 

 

 

 

 

 

 

 

 

 

 

not supplied. 
 
A standard 3­pin disconnect IEC power cable is included. 
 
 

Installation:

 

 
The MLC8B mounts in a standard 19 inch rack and occupies one rack unit of space. 
 
Connections to the unit are made on the rear panel. Please note that the 25­pin DB

   

 

 

 

 

 

 

 

 

 

 

 

 

 

 

female connector labelled

AUX 1

is used to connect the analog inputs while the 25­pin

 

 

 

   

 

   

 

 

 

 

 

 

 

DB male connector labelled

AUX 2

is used to connect the analog outputs. The 9­pin

 

 

 

 

 

   

   

 

 

 

 

 

 

DB female connector labelled

SERIAL COMM

is an RS422 control port for external

 

 

 

 

 

   

 

 

 

 

 

 

control of the device and is typically connected to and MLC8BR REMOTE control panel.

   

 

 

   

 

   

 

 

 

 

 

Please refer to the rear panel layout diagram and the detailed connector diagram for

 

   

 

 

 

 

 

 

 

 

 

 

 

connectors 

AUX1, AUX2 and SERIAL COMM

 
The MLC8B is factory calibrated to operate at the nominal level of ­20dBFS = 0. The

 

   

 

   

   

 

 

   

     

 

unit may be field calibrated for nominal levels of ­18dBFS, ­14dBFS or ­12dBFS, please

 

 

 

 

 

 

 

   

 

   

 

 

refer to the calibration table in this manual.
