OWNER'S MANUAL AA120M MIXER AMPLIFIER QUICK START EXAMPLES Example 1 - System Paging, BGM, and MOH with Emergency Page Override When a page signal is received from INPUT 2 and the RMT MUTE terminals are shorted, the page will be the only audio heard in the main system because BGM will be muted. If an emergency page comes into INPUT 1, all inputs will be muted except for the emergency page. Note: Zone 3 MOH output will not be muted or affected by either page scenario. • Connect a paging mic to INPUT 1.
OWNER'S MANUAL AA120M MIXER AMPLIFIER Example 2 - Priority Attenuator Override Application with Message Repeater and BGM This application makes use of the internal relay and 24VDC in conjunction with Atlas Sound optional "PA" override volume controls. A typical scenario would be for a Fire Station, where the background music is turned down by the wall volume controls in the evening.
OWNER'S MANUAL AA120M MIXER AMPLIFIER Example 3 - Optional Plug-In Module Application The AA120M incorporates a module port that supports a variety of system options. For this example, a plug-in chime module is used to announce a request for building entry. The chime sound would only go to one speaker located over a security guard's area. In addition to the chime module, there is paging, background music, and message on hold connected. • Connect the customer's PBX page port to INPUT 1.
OWNER'S MANUAL AA120M MIXER AMPLIFIER Example 4 - Remote Level Control Utilizing the optional plug-in modules and the Atlas Sound wall mounted VCA attenuators, we can produce a conference room or hotel ballroom PA system with both remote Master and remote Background Music (BGM) volume controls. Inputs 1-4 are wired to the microphone wall plates in the room and the BGM comes from a CD player or Satellite radio receiver. • Connect the mics to INPUTS 1-4.
OWNER'S MANUAL AA120M MIXER AMPLIFIER Example 5 - Hotel Room Combining Using Two AA120Ms This example utilizes the combining feature of the Atlas AA120M mixer amplifiers. The drawing on the following page shows the equipment connections for two hotel ballrooms, separated by a moveable air wall. They hotel needs to be able to have the audio system operate has one large unit (air wall open) or two discreet systems (air wall closed).
