The CX462 is 152.5mm deep but a depth of 200mm should be allowed to clear connectors. Stereo/Music Inputs The music section of the CX462 has six stereo inputs. These line inputs are suitable for most music sources such as compact disc players, tape players and receivers etc.. All inputs are unbalanced and use RCA type phono connectors. -
Page 9: Music Control - Local Or Remote
The music source and music level control functions can be controlled from either the front panel or a remote control plate located up to 100m from the CX462. There are two remote control plates available for the CX462, the RSL-6 and the RL-1. The RSL-6 should be used... -

Master microphone level can be controlled locally via the front panel rotary control, or through a remote wall plate up to 100m away from the unit. To configure the CX462 for STANDARD WIRING CONVENTION remote level operation, the front panel switch USE TWO CORE SCREENED CABLE must be in the 'REMOTE' position. -

6.7 Microphone over Music priority The CX462 provides a facility whereby microphone signals can be given priority over music signals. When a signal is detected on any of the mic inputs, all music signals are attenuated to a level determined by the front panel attenuation control. Once there is no microphone signal present, the music will restore to the previous settings. -

(inner core) to pin 3 and make no connection to pin 2. The music output of the CX462 can operate in either stereo or mono mode. The default setting is for the CX462 to operate in stereo mode. In mono mode, all stereo signal sources are mixed internally and output the same signal to both left and right channel music outputs. -

Page 18: Remote Music Mute - Fire Alarm Interface
The CX462 provides a facility to mute the music signals only, by using a fully isolated pair of contacts. This is usually a relay mounted close to the CX462, which is powered by the fire alarm control panel. The relay can either be closed or opened in an alarm condition, but the internal jumper J13 MUST be set to the corresponding position: M N/C: Alarm condition when the relay opens. -

12.4 Microphone access switches not working correctly The CX462 leaves the factory configured to bypass the microphone access contacts for all four microphone inputs, so that when the product arrives, all inputs will be enabled. Internal jumpers J1 to J4 bypass access contacts for microphones 1 to 4 respectively. To enable access switching on one of the microphone channels, disconnect the corresponding jumper. -
