Check the listing for details. Atlas IED AA-PPRC Control, Remote, Priority Paging. Condition: New. Listed at 283.99 USD. A two in two out speaker level relay switcher, the AA-PPRC functions as a gatekeeper for the separate channels giving you priority control. Intended for applications where paging must be heard over music or an audio presentation, the trigger function mutes the program channel. Once the page has completed, the audio on the program channel will resume automatically with a recover time adjustable from 1 to 30 seconds. The trigger to mute the channel can be high level or line-level audio input, or a range of DC voltage, so placement of the controller is not critical. Flexible enough to accommodate 8Ω or 25/70.7/100V systems, the AA-PPRC is the right choice for new or retrofit applications.Includes12VDC UL Power SupplyAtlas Sound AA-PPRC Features:2 Channel350 W @ 70.7V Per ChannelAudio High Level Trigger Sense With Threshold Adjust3V - 45VAudio Line Level Trigger Sense With Threshold Adjust20mV - 2VCompact Size H 1.5"x W 4" x L 4.5" (H 38.1 mm x W101.6 mm x L 114.3 mm)Contact Closure TriggerDC Trigger 5V - 24VFinish Black with White LetteringPhoenix Type I/O ConnectorsRelay Recover Adjustment 1 - 30 SecondsRelay Trigger Threshold AdjustSpeaker Line Remote SwitcherAtlas Sound AA-PPRC Specifications:Height: 1 1/2" (3.81 cm)Width: 4" (10.16 cm)Depth: 4 1/2" (11.43 cm)Shipping Weight: 2.00 lbs (0.91 kgs)Frequency Response: 20 Hz - 20 kHz FlatConnector Type: Four Position Detachable Phoenix ConnectorFinish: BlackLoad Capacity: 5 AMPSCompatability: 8O, 25V, 70.7V, 100V Systems
