Russound A BUS A-H484 Multisource, Multizone Hub

A- H484 Overview

The Russound A-H484 is a four-zone, four-source audio distribution hub used with A-BUS amplified keypads. The A- H484 can be linked to another A-H484 to increase the number of zones in a system.

1. Amplified Keypads
   The A-H484 has coupled zone outputs in two groups of four (A and B) that support each of the A-K4 keypad per zone. Source selection is shared by coupled zone outputs. Connect up to eight A-BUS amplified keypads to the A-H484 with CAT-5 cable using RJ45 CAT-5.
   NOTE: A-BUS keypads must be set to multisource mode to be used with the A-H484 hub. See A-K4 keypad installation manuals for complete details.
   The zone output on the A-H484 is a CAT-5 RJ45 connector using T568A wire configuration. The A-K4 has an RJ45 connector with T568A wire configuration.

2. IR Emitters
   Routed IR Outputs and Common IR Output. Connect an IR emitter such as the IRE-1 to each of the 4 IR connectors on the A-H484. When a source is selected from a zone, the IR signal received through the zone’s keypad is routed exclusively to that source via the A-H484’s Routed IR outputs. This allows the use of multiple sources of the same brand (for example, two identical DSS units). The Common IR output sends out all IR signals and can be used with an IR flasher that blankets all source components.

3. Trigger Output
   The 12VC trigger output can be used to control a switched AC outlet to turn power on and off to source equipment. The trigger voltage is sent when any zone is in the system is turned on. When the ALL OFF command is used, the trigger is turned off. Use a 1/8” male 2-conductor jack (not included).

4. Link In and Link Out
   The Link In and Out is used to connect multiple A-H484 hubs to allows for use of additional A-BUS keypads. The connection is made using an RJ45 patch cable. The Link connects the Routed IR, Common IR, and Status. Audio signals are shared with linked A-H484 hubs using “Y” cables to split the audio outputs. The A-H484 CANNOT be linked to single-source A-BUS Hubs such as A-H2, A-H4P and A-H1, as these use a different format for linking.

5. Sources
   The A-H484 has four stereo audio inputs that support connections to multiple audio sources. If sources are connected to an existing home theater receiver, they can be shared with the A-H484 by using “Y” connectors for the audio outputs.

6. Keypad Connection to A-H484 Hub
   Each keypad connects to a Keypad Output port on the A-H484 hub. Connections use CAT-5 cable with an RJ-45 connector using T568A CAT-5 wire configuration. CAT-5 cable length should be 150 feet or less from hub to keypad.

7. Power Supply
   The A-H484 hub and amplified keypads are powered by the A-PS 24VDC/2.5A power supply. Each row (A and B) must have its own power supply. The A-PS should be plugged into an unswitched AC outlet (one that is live all the time). When the A-PS is providing power, the A-H484’s POWER LED will illuminate once a keypad is turned on.

8. Installation
   Install the A-H484 near the system’s source equipment using screws or hook and loop fastener. The A-H484 will also fit many structured wiring distribution panels.

9. Operation

The A-H484 is designed to be used with A-K4 and  multisource-capable amplified keypads.  A-K4 keypad can be operated manually or by using  the USRC remote control. If using installed IR emitters, sources can be operated with their own remote control by aiming it at the IR window on an A-K4 keypad.

When the A-K4 keypad is set in multisource mode, tap the power button to toggle through and select a source. The top LEDs of the volume indicator show (from top to bottom) the source that is selected (top LED is source 1, next LED down is  source 2, etc). For a clean installation when wiring from a Keypad Port, use an RJ-45 CAT-5 patch cable to connect from the keypad port to an RJ-45 wall plate (optional). Using the same RJ-45 T568A CAT-5 wiring configuration, use CAT-5 from the RJ-45 wall plate to the keypad.
