User manual RUSSOUND A-LC2

[. . . ] The audio is amplified by the room's A-BUS® Amplified Control Module and played through the speakers in that room. The rest of the system continues to operate independently. · The A-LC2 can also be used to connect the audio output of a television so TV sound can be heard through a room's speakers. 3 SENSITIVITY ADJUSTMENT The sensitivity adjustment determines the level of signal needed before the A-LC2 will switch from the main source to the local source. Try the lowest level first (fully counter-clockwise) and gradually raise the level until the switching occurs. [. . . ] A-BUS® Hubs: All components of the A-BUS® system must be wired centrally to a Hub located near your source equipment. The Hub provides the connection for source equipment, volume controls, infrared emitters and power supply. The A-H484, A-H4, A-H4D, and A-H2 are examples of A-BUS® Hubs. The A-H484, A-H4, and A-H2 are surface-mount units. The A-H4D is an in-wall Decora® style unit. Power Supply: The power supply plugs into the Hub. The Russound® A-PS 24VDC/2. 5A unit is an example. A-LC2 FEATURES 1) 2) 3) 4) 5) Stereo audio input Automatic switching between local and main source Switching sensitivity adjustment Switching delay adjustment Decora® faceplate INSTALLATION NOTES · Using the A-LC2 requires that the status feature be disabled on the A-BUS® Hub as well as on ALL A-BUS® Amplified Control Modules in the system unless it is being used. · Before connecting the A-LC2: - Make sure that the A-PS power supply is not connected to the A-BUS® Hub or, if you are using an A-BUS® Ready receiver, that the receiver is off. - Make sure that the STATUS input on the A-BUS® Hub is not connected. · The recommended maximum length for use with standard CAT-5 cable is 250 feet. · Once all of the connections have been made, the A-PS power supply can be connected to the A-BUS® Hub or, if you are using an A-BUS® Ready receiver, the receiver may be turned on. 5 MOUNTING Locate the A-LC2 near the local source. Check all connections and test the system's operation before installing the A-LC2 into the wall. Using the included hardware, install the A-LC2 into a standard UL/CSA approved electrical J-Box as shown. A-LC2 SPECIFICATIONS Power Requirements: Input Sensitivity: Switching Delay: CAT-5 Connection: Dimensions (in-wall): Weight: 24VDC, 24mA 35mV to 280mV 10 sec. 110 Punchdown 1. 75"W x 2. 875"H x 1. 75"D (45x73x45mm) 6 oz. (170g) 6 OPERATION When the A-LC2 senses an audio signal at its local input, the main audio is switched out locally, the local audio is switched in, and the status light on the connected Amplified Control Module turns on (if not already on). When local audio is no longer sensed, the A-LC2 will switch back to the main audio. If the main audio is not running, the Amplified Control Module will automatically turn off (AKP2) or mute (A-VC), only if "Status" is enabled on the hub and there is a switched outlet on the main audio source. 1 CAT-5 CONNECTIONS A CAT-5 cable is used to connect the A-LC2 to a keypad output on an A-BUS® Hub or A-BUS® Ready receiver, and to an A-BUS® Amplified Contol Module. For clean installations, use RJ-45 CAT-5 patch cables (use T568A RJ-45 wire configuration) to connect from the Hub to an RJ-45 Wall Plate (optional), and then wire from the Wall Plate to the A-LC2 (see diagram). The A-LC2 and the Amplified Control Module have 110 punchdown connectors for the 8 individual conductors of the CAT-5 cable (use a punchdown tool with a 110 blade to insert conductors). [. . . ] To return for repairs, the unit must be shipped to Russound ® at the owner's expense, along with a note explaining the nature of the service required. Be sure to pack in a corrugated container with at least 3 inches of resilient material to protect the unit from damage in transit.
