Figure 5 - MS-2002 typical Speaker Station and Belt Pack Connections.
Typically, a headset is connected to the front panel of the MS-2002, and the DIP switches are set to the monaural operation (default setting) so that both intercom channels as heard in the monaural headphones (binaural headphone operation is not supported). Note that belt packs use less power than speaker stations, and you can daisy-chain more of them on a signle cable run. Avoid very long cable runs with daisy-chained speaker stations. This example shows how you would “home run” an SS2002 speaker station when the cable is very long. Also, set the Combine/Isolate switch to the Isolate position. With this setting the 2 intercom channels are completely separated.
