A-H2 Features
The Russound A-H2 is a two-zone, one-source audio
distribution hub used with A-BUS amplified keypads. The
A-H2 can also be linked to other A-BUS hubs (such as the
A-H4) and to A-BUS Ready stereo receivers in order to
increase the number of zones in a system.
NOTE: Before installation, review the manuals included
with each component in the system.

4 Expansion Input
The Expansion Input is used to connect the A-H2 with
an RJ45 patch cable to other A-BUS single-source hubs
or to an A-BUS-Ready product to increase the number
of rooms in a system. The Expansion Input connects the
Common IR, Status, and the audio source signal. Single-
source A-BUS Hubs such as A-H4, A-H4P and A-Hl all use
the same format for linking. The A-H484 multisource Hub
is different and cannot be linked to single-source hubs in
this manner.
The Link Out or A-BUS Ready subzone output of one
device must be connected to the Link In (Expansion Input
of A-H2) of the subsequent device. NEVER connect the
Link Out to another Link Out or A-BUS Ready output. This
may damage the components and void the warranty.
NOTE: Each hub in the chain requires its own A-PS power
supply.
5 Source
The A-H2 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-H2 access to any
audio source connected to that receiver. Alternatively,
a single audio source can be connected directly to the
A-H2.
6 Power Supply
The A-H2 hub and amplified keypads are powered by
the A-PS 24VDCl2.5A 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-H2's
POWER LED will illuminate.
7 Operation
A-K3 keypads can be operated manually or by using
the A-LRC2 remote control. A-VC2 volume controls
are operated manually using the rotary knob. If using
installed IR emitters, sources can be operated with their
own remote control by aiming it at the IR window on an
A-K3 keypad.
8 Installation
Install the A-H2 near the system's source equipment
using screws or hook and loop fastener.
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 switch on the hub to the
"STATUS" position.
Using a Russound 846C 120Vl12VDC 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 (A-VC2 will mute).
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.
3 Status
2 IR Emitters
Common IR Outputs. Connect an IR emitter such as the
845.1 to each of the 4 IR connectors on the A-H2 (you
need use only one IR emitter if you've connected a single
source directly to the A-H2). The IR signal that is received
through a zone's amplified keypad is routed to the A-H2's
Common IR outputs. This allows remote operation of
sources such as CD, DVD or DSS from each zone.
1 Amplified Keypads
Connect two A-BUS amplified keypads. A CAT-5 cable is
used to connect each A-K3 or A-VC2 to a keypad output
on the A-H2 Hub. For clean installations, use RJ45 CAT-5
patch cables to connect from the hub to an RJ45 wall
plate (optional), and wire from the wall plate to the
keypad. The A-K3 has an RJ45 connector with T568A
wire configuration and the A-VC2 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).
