Figure 5 - Typical connections using one SPS-2001 Power Supply for two intercom channels. The two program sources are
monitored independently by their intercom channels. All audio (program and intercom) is monitored as a monaural mix in the
SPS-2001 speaker. The US2000A is set for monaural speaker output (default).
