General Information
Speaker Master Module
The Model 69679-001 Speaker Master Module (see Figure 2) works with speaker remote modules in an
Elemec3 system to monitor speaker coil integrity and to control volume levels at speakers driven from
central amplifiers (see Figure 1). The Elemec3 speaker master module changes individual loudspeaker
power levels on command from a central location on a system-wide or individual speaker basis. The
range of adjustment is in steps from off/mute to full power. The speaker master module transmits power
level tap commands to the remote speaker modules and receives speaker coil health check status from the
remote speaker modules. Each speaker master module controls up to four amplifier channels.
Speaker Remote Modules
Install the Model 13317-001 (8-ohm, 25-watt) or Model 13317-002 (16-ohm, 30-watt) Speaker Remote
Module(s) with each speaker requiring remote adjustment and monitoring. The speaker remote modules
receive health check requests/speaker tap control commands from the speaker master module via an RF
data modem (see Figure 3). The speaker remote modules check loudspeaker integrity by sampling
speaker voice coil continuity. The modules report their health status to an E3 controller via RF data
modem. The maximum number of remote modules in each speaker loop is 24. Use 14 AWG (2.5mm
2
)
minimum, individually shielded twisted pair cable to wire the speaker remote modules.
System Requirements
E3 speaker master controllers communicate with the Elemec3 controller via CAN bus. The devices
receive power through the CAT5 power/CAN bus cable or from a separate 24 V dc power supply. The
power requirement of the combined CAN bus devices must not exceed the CAN bus cable and/or separate
24 V dc power supply ratings.
The maximum number of remote modules in each speaker loop is 24. Use individually shielded twisted
pair cable to wire the speaker loops. Connect the cable shield to earth ground at only one location
(usually the amplifier location) to avoid the presence of ground loops.
