A-BUS System Overview: Instead
of multi-channel amplifiers, speaker selector boxes, autoformers,
impedance-matching equipment and long runs of expensive speaker wire, A-BUS
audio distribution includes amplified in-wall volume controls, and wiring
installation time is significantly reduced as only a single 8-connector CAT-5
wire (not included) is run to each location. Simply add A-BUS to your
existing stereo/home theater system with the A-H4 4-Zone Hub and the A-BUS A-KP2
Amplified Controls (not included) will provide independent volume and
source control to each room where an A-BUS module is installed. Each control
contains a stereo amplifier rated to deliver 7.5 watts RMS per channel; the AC
current to power each amplifier is delivered via the CAT-5 cable. The system
also includes IR remote sensing and retransmission to let you control your
components from any of the volume control locations.
A-BUS Distribution Hub: The
A-H4 is the system's primary interface with your existing system; all components
of the A-BUS system must be wired to this component. Includes stereo RCA inputs
(and outputs, to route the signal back to your receiver or onto a second A-H4
module), jacks for IR emitters, and RJ45 jacks for connecting four CAT-5 cables.
Status Feature: The Status
feature provides two functions - Visually confirms when the source
component is on / When the source component is
turned off, all Amplified Modules will also turn off. The Status feature requires that the
source component has a switched AC outlet. To enable the Status feature:
Note: When the source is on and supplying
status voltage to the Hub, the Amplified Module's LED indicator will
illuminate green. When the source is turned off, all Amplified Modules that
are on will also turn off (the optional A-VC2 will mute)
- Move the status jumper on all
Amplified Modules to the "Enabled" position
- Move the status switch on the Hub
to "STATUS" position
- Using an optional Russound Model
846C 120V/12VDC or comparable 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.
Inputs and Outputs:
- 4 RJ45 CAT-5 jacks:
Communicate directly with the A-KP2 amplified keypads (not included).
CAT-5 cable is recommended for cable runs of not more than 250 feet. You
will need to terminate your CAT-5 cable with RJ45 plugs.
- DC Power input: Accepts
connection from the A-PS 4-amp power supply (not included). There is
a red LED that illuminates when power is connected.
- DC Status input: If you
intend to use the System Status feature of the A-BUS system, a Russound
Model 846C Power Supply (not included) can be connected to the status
input on the A-H4. The power supply should then be plugged into a switched
AC receptacle, usually on the back of the audio receiver being used. There
is a green LED that illuminates when a System Status Power Supply is
connected and power is on.
- Link In/Link Out: Dual RJ45
jacks used to connect the A-H4 Hub to additional A-H4s or to other A-BUS
single-source Hubs or an A-BUS-Ready stereo receiver in order to increase
the number of zones in a system. The Link connects the Common IR, Status,
and the audio source signal (note: each Hub requires its own A-PS power
supply!). The Link Out can also be used to directly connect just one
additional Amplified Module.
- 4 Common IR Outputs: Connect
the 1/8" plug from the 1584.1 or 845.1 Micro-Emitter (not included)
to one of these jacks to send the IR signal to your source components. If
you use four 1584.1 Micro-Emitters (not included), you can control up
to 8 IR-controlled devices. There is a red LED to confirm when IR commands
- Audio In: Left & Right
gold-plated RCA jacks accept a line-level signal from your source component.
- Audio Out: Left & Right
gold-plated RCA jacks. This buffered audio output can be used to connect to
an additional A-H4, or to an amplifier or processor.
- Power Supply: A-PS
- Status Power: 12VDC/100mA
- Keypad Connection: RJ-45
- Link Connection: RJ-45 T568A
- Emitter Connections:
1/8" Male. Tip (+), sleeve (-)
- Dimensions: 6.5" wide x
3" high x 1.5" deep (including all protrusions)
