configuration for large intercom systems when you want to operate the US2002 as a master speaker station, with one
speaker to monitor both intercom channels. In this configuration, the SPS2001 and PS2001L Combine/Isolate switches
are set to the Combine position. With this setting, all intercom stations connected to the SPS2001 are combined on
intercom channel 1 and all intercom stations connected to the PS2001L are combined on channel 2. The amplified
speaker in the SPS2001 is used as the speaker output for the US2002 and the US2002 dip switches are set for monaural
operation (default setting) so that both intercom channels are heard in the speaker. The PA-KP local power supply is
optional. When a PA-KP is connected, the US2002 automatically disconnects from system power. Since the US2002 is
not drawing power from the intercom system, more system power is available for additional belt packs, etc.
