Note: This equipment has been tested and found to comply
with the limits for a Class B digital device, pursuant to part
15 of the FCC rules. These limits are designed to provide
reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment o
and on, the user is encouraged to try to correct the interference
by one of or more of the following measures: reorient or relocate
the receiving antenna; increase the separation between the
equipment and receiver; connect the equipment into an outlet on
a circuit di erent from that to which the receiver is connected, or
consult the dealer or an experienced radio/TV technician for help.
This Class B digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe B est conforme à la norme
NMB-003 du Canada.

CONNECTION INSTRUCTIONS FOR A-H4D. REFER TO NUMBERED DIAGRAM ON REVERSE.

1 Amplified Keypads

Connect four A-BUS amplified keypads. A CAT-5 cable is
used to connect each A-K4 to a keypad output (KP1 - KP4)
on the A-H4D Hub. CAT-5 connections for the A-H4D are
110 punchdown. The A-K4 has an RJ-45 connector with
T568A wire configuration.

2 IR Emitters

Common IR Outputs. Connect an IR emitter such as
the 845.1 to each of the 4 IR connectors on the front of
the A-H4D (you need use only one IR emitter if you’ve
connected a single source directly to the A-H4D). The IR
signal that is received through a zone’s amplified keypad
is routed to the A-H4D’s Common IR outputs. This allows
remote operation of sources such as CD, DVD or DSS
from each zone.

3 Status

The Status option provides visual indication when source
equipment is powered on and permits a system-wide ‘all
off’ function.

To enable Status:

Move the status jumper on all amplified keypads
to the “Enabled” position.

Move the status jumper on the back of the A-H4D
to the “2-3” position.

Using a Russound 846C 120V/12VDC or
comparable power adapter, connect the coaxial plug end
to the STATUS input on the hub, and plug the adapter
into a switched AC outlet on the source component.

Status function and operation:

When the source is powered on, the Status circuit
is powered by 12VDC and turns the keypad’s Status LED
to green. This indicates to the user that the source is on
and ready to receive remote control commands.

When the source is powered off (remotely or
manually), it shuts off the 12VDC Status power connected
to it, and turns off all the keypads (green LED off)
connected to the hub.

IMPORTANT: When the status feature is enabled, it
must be supplied with power for proper operation with
accessories such as the A-LC3 Local Source Input Module.

4 A-H4Dx Expansion Hub

The A-H4Dx is an expansion hub for the A-H4D that
provides connections for four additional amplified
keypads. It plugs into the side of the A-H4D. Multiple
A-H4Dx hubs can be added. Each A-H4Dx requires its
own A-PS power supply.

5 Source

The A-H4D has one stereo audio input, and it can be
connected to multiple audio sources via the Tape 2 or
Zone 2 output of a stereo or home theater receiver.
Connecting to a receiver gives the A-H4D access to any
audio source connected to that receiver. Alternatively,
a single audio source can be connected directly to the
A-H4D.

6 Power Supply

The A-H4D hub and amplified keypads are powered by
the A-PS 24VDC/2.5A power supply. The A-PS should be
plugged into an unswitched AC outlet (one that is live all
the time).

7 Operation

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.

8 Installation

Install the A-H4D in a standard UL/CSA approved double­gang electrical J-box. Choose a spot near the receiver and
source equipment. Check all connections and test the
system’s operation before installing the A-H4D into the
wall.
