Room Three is shown using an Emtech Electronics IA204-R including mic/line level inputs, pre-amp, mixer, 20 watt
amplifier and integrated RCM switching. This in-wall amplifier/mixer includes a locking cover to prevent tampering.
The IA204-R single unit coupled with speakers provides the entire sound reinforcement package for a small room.
Room Four utilizes an Emtech ISA-253 two channel mic/line pre-amp/mixer and 15 watt amplifier with an Emtech
RCM-S switch to control the RCM-42B. This in-wall amplifier/mixer also includes a hinged locking cover. All that is
needed to complete the solution, are speakers.
Smart Distribution Amplifier
The RCM-42B and RCM-82B can also be used as smart distribution amplifiers. Figure 4 shows how a RCM-42B can
be used as a smart distribution amp. A simple bank of switches allows remote selection of the active outputs. Using an
RCM-82B, up to eight outputs can be distributed.
