6. Zone Remote Jacks
These inputs are for the optional remote controls: CSR-V, CSR-2SV, and CSR-3SV.
7. Isolated Auxiliary Output*
This sends a transformer isolated mono signal for a music-on-hold system, or for a separate mono
auxiliary zone. The +/- outputs are 600 Ohm transformer isolated so that they can interface to another
system (telephone or remote amplifier) without having undesirable ground interaction. The level control
adjusts the output level to match a variety of applications.
NOTE
: THE P11 JUMBER IS LOCATED ON THE PCB OF THE MIXER. AS SHIPPED, THE
SOURCE FEEDING THE AUXILIARY OUTPUT IS SELECTED BY THE ZONE 1 SOURCE
SELECTOR. WHATEVER SOURCE IS SELECTED BY ZONE 1 IS WHAT COMES OUT OF THE
AUXILIARY OUTPUT. THIS CAN BE CHANGED TO ALWAYS BE SOURCE 3 BY REMOVING
AN INTERNAL JUMPER CAP.
8. Page Assign
This allows you to assign pages between output zones. This can be accomplished with a simple re-
mote selector switch or can be hard wired if pages are to the same zone every time. Shorting a zone
pin (Z1 or Z2 or both) to the “G” pin assigns the page to that zone.
9. Source Inputs
Connect your RCA equipped source signals here.
10. Link Jacks
These inputs allow you to network multiple CSM mixers together. The units are connected by standard
category 5 UTP cables. The length of the linking cable must be kept to under 2.4 meters.
11. Music Mute
This can be wired to a switch that mutes the background music when pin 2 is shorted to ground pin 1.
NOTE 1 : MUSIC MUTE DOES NOT MUTE THE PAGING MIC AND DIRECT INPUT. IN AN EMERGEN-
CY SITUATION, THE SYSTEM USER MAY NEED TO USE THE PAGING MIC FOR EMERGENCY AN-
NOUNCEMENTS.
NOTE 2 : WHEN THE CSM-21 AND CSM-32 MIXERS ARE LINKED TO PROVIDE AN ADDITIONAL OUT-
PUT ZONE, MUSIC MUTE WILL BE APPLIED TO OTHER CSM-21 AND CSM-32 MIXERS THROUGH
THE LINK CONNECTION.
12. Direct Input
The Direct Input signal is buffered and sent directly to the outputs. This is useful for alarms, emergency
pages, or for another priority level of paging. The gain control adjusts the volume of Direct Input to the
Zones.
NOTE : THE DIRECT INPUT REQUIRES A LINE-LEVEL SIGNAL, A MICROPHONE PRE-AMP IS NEED-
ED TO BOOST A MIC LEVEL SIGNAL BEFORE IT CAN BE RUN INTO THE DIRECT INPUT.
Items with * are the controls only found on the CSM-32 mixer.
