Amplified Keypad: The Russound A-K4 is an in-wall amplified keypad used with A-BUS hubs and controllers in a distributed audio system. It can be used with both single and multi-source A-BUS hubs/controllers. The A-K4 provides source selection and control with backlit push buttons, plus an IR window to receive remote control signals.
- Power: Turns zone On or Off when pressed once.
- Source Select: When the keypad is set in "Multisource"
mode, the power button is used to toggle through and select a source.
source 2, etc
- Gain: The two rotary trim potentiometers on the side of the
A-K4 provide adjustment of audio gain. These are used to
set the maximum allowable volume for the left and right speakers connected to the A-K4.
- Volume: The volume up/down buttons control the speakers in the room that are connected to the A-K4.
- Speaker Outputs: The Speaker Output connections provide speaker-level audio output for a pair of 8-ohm speakers. These screw-down terminals accept up to 16 gauge speaker wire.
- Line Outputs: The Line Out provides a variable line-level audio output connection for an external amplifier or powered subwoofer. These screw-down terminals accept up to 22 gauge/4 conductor speaker wire.
- RJ 45 Connector: The RJ-45 input provides a connection for the CAT-5 cable from an A-BUS hub/controller to receive an audio signal, pass-through IR and power over the CAT-5 cable. The recommended maximum length for standard CAT-5 cable is 150'.
IR Receiver: The IR receiver on the front-panel receives IR signals from a remote control. Source components attached to IR emitters in an A-BUS system can be controlled with their own remote controls aimed at the A-K4 keypad.
Status LED: The status LED is green on the keypad when the system is on (keypad can be on or off)
Installation Note: Typical installations place one A-K4 in each room of the A-BUS system.
