6 MPA-626: Installation and Operation Manual

Wiring a CPM-4 to MPA-626 Amplifiers

Wiring Multiple CPM-4 Microphones to an MPA-626

The access inputs can also trigger the following functions:

1. Chime Location of Jumpers J3,4,5,6,7&8

Optional depending upon the setting of

jumpers J8 and J7 for Mic 1 and 2

respectively

2. Muting of music signals

Optional depending upon the setting of

jumpers J4 and J3 for Mic 1 and 2 respectively.

Repositioning Jumper J6 sets the amount of

attenuation for Mic 1&2. The 30dB setting is

intended to provide a 'voice over' function. The

60dB setting has two intended uses:

(i) To provide a more dramatic 'voice over'

during announcements.

(ii) When restoration relays are used they

could increase the volume of the music signal,

the 60dB attenuation will prevent this from

happening.
