Russound ABUS A-H484 User manual

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.
The A-H484 multisource hub supports four audio
sources in a four-zone A-BUS system. Each zone is
expandable to two rooms with inputs for A-K4 keypads.
You can select any source independently in each zone at
the keypad or with an A-LRC2 remote control.
NOTE: The A-VC2 amplified volume control is not
multisource-capable and is not recommended for use
with the A-H484 multisource hub.
A-H484 Features
• Four line-level audio inputs
• Four zone coupled outputs (2 keypads per zone)
• 12VDC trigger output
• Link in and out
• 4 routed, 1 common IR outputs

A-H484
Multisource, Multizone Hub
for A-BUS®System
Installation Manual
1 Amplified Keypads
The A-H484 has coupled zone outputs in two groups
of four (A and B) that support one or two A-KP2 or A-K4
keypads 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. For clean
installations, use RJ-45 CAT-5 patch cables to connect
from the hub to an RJ-45 wall plate (optional), and wire
from the wall plate to the keypad.
NOTE: A-BUS keypads must be set to multisource mode
to be used with the A-H484 hub. See keypad installation
manuals for complete details.
The zone output on the A-H484 is a CAT-5 RJ-45
connector using T568A wire configuration. The A-K4
has an RJ-45 connector with T568A wire configuration
and the A-KP2 has a 110 punchdown connector for
the 8 individual conductors of the CAT-5 cable (use a
punchdown tool with a 110 blade to insert conductors).
2 IR Emitters
Routed IR Outputs and Common IR Output. Connect an
IR emitter such as the 845.1 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 (e.g., ACT-1) 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 RJ-45 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.
NOTE: The A-H484 is not recommended for use with the
Russound CAV6.6 controller/amplifier.
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 Multisource Mode for A-K4 Keypad
When used with the A-H484, the A-K4 must be set to
multisource mode by moving a jumper on the keypad.
The jumpers and pins are located under the faceplate on
the right side of the keypad (facing front). The pins are
jumpered to select between 1, 4 and 6 sources. Set for 4
sources when used with the A-H484 hub (4 sources = top
two pins jumpered).
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-KP2 and
A-K4 multisource-capable amplified keypads.
A-KP2 and A-K4 keypads can be operated manually or
by using the A-LRC2 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).
