A-K3
Amplified Keypad with Multisource Capability
for A-BUS® System
Installation Manual
CONNECTION INSTRUCTIONS FOR A-K3. REFER TO NUMBERED DIAGRAM ON REVERSE.
A-K3 Overview
The Russound A-K3 is an in-wall amplified keypad used
with A-BUS hubs and controllers in a distributed audio
system. It can be used with both single- and multi-source
A-BUS hubs/controllers. The A-K3 provides source selec-
tion and control with backlit push buttons, plus an IR
window to receive remote control signals.
The volume up/down buttons control the speakers in
the room that are connected to the A-K3. Typical installa-
tions place one A-K3 in each room of the A-BUS system.
The Line Out connection on the A-K3 can be used to
feed a separate powered subwoofer or to connect an
external amplifier for more power to a larger listening
area.
A-K3 Key Features
• Power On/Off button (acts as source select with
multi-source hubs/controllers)
• Volume trims for L/R balance and maximum level
settings
• Built-in IR receiver with IR confirmation LED
• IR control of settings and sources via A-LRC2 optional
remote
• Line Out connection for external amp or powered
subwoofer
A-K3 Specifications
Output Impedance: 8 ohms/channel (1 pair speakers)
Input Impedance: 10 kohms
Power Requirements: +24VDC 660mA peak
CAT-5 Connections: RJ45
Dimensions (in-wall): 1.75”W x 2.875”H x 1.75”D
(45x73x45mm)
Weight: 5.5oz. (160g)
5 Source Mode Jumper for Single/Multisource
The single/multisource jumpers set the A-K3 to be used
with either single- or multi-source A-BUS hubs/control-
lers. The jumpers and pins are located under the face-
plate on the right side of the keypad (facing front).
The pins are jumpered to select between 1, 4 and 6
sources. 1 source = no jumper; 4 sources = top two pins
jumpered; 6 sources = bottom two pins jumpered.
6 Gain Control for Maximum Levels
The two rotary trim potentiometers on the side of the
A-K3 provide adjustment of audio gain. These are used to
set the maximum allowable volume for the left and right
speakers connected to the A-K3.
7 Keypad Connection to A-C68 Controller
Each keypad connects to a Keypad Output port on the
back of the A-C68 controller. Connections are made using
CAT-5 cable with an RJ45 connector.
The Keypad Ports are located on the back of the A-C68
on the left. Connections at the Keypad Ports are made
with RJ45 connectors using T568A CAT-5 wire configura-
tion. CAT-5 cable length should be no longer than 150
feet from controller to keypad.
If used in a system with A-K5L keypads, when connecting
A-K3 keypads to the A-C68, the keypad dip switches on
the controller’s front programming center must be set in
the UP position. Dip switches correspond to numbered
keypad ports.
If used in a A-C68 system with no A-K5L keypads, set the
keypad dip switches in the UP position.
For a clean installation when wiring from a Keypad Port,
use an RJ45 CAT-5 patch cable to connect from the key-
pad port to an RJ-45 wall plate (optional). Using the same
RJ45 T568A CAT-5 wiring configuration, use CAT-5 from
the RJ45 wall plate to the keypad.
8 Installation
Check all connections and test the system’s operation
before installing the A-K3 into the wall. Using the includ-
ed hardware, install the A-K3 into a standard UL/CSA
single-gang electrical J-box.
1 RJ45 Connector for CAT-5 Connection
The RJ45 input provides a connection for the CAT-5 cable
from an A-BUS hub/controller to receive an audio signal,
passthrough IR and power over the CAT-5 cable. Use the
T568A wiring standard. The recommended maximum
length for standard CAT-5 cable is 150 feet.
Before connecting the A-K3, disconnect the power sup -
ply from the A-BUS hub/controller and disconnect the
Status power supply if used.
2 Line Out Connector for External Amplification
The Line Out provides a variable line-level audio output
connection for an external amplifier or powered sub-
woofer. An amplifier provides more power to a large
listening area, and a powered subwoofer adds extended
bass response.
Use 22AWG four conductor, two-pair twisted shielded
cable to connect to the Left positive (+) and negative (-),
and Right positive (+) and negative (-) screw down termi -
nals on the back of the A-K3.
Terminate the four conductor two-twisted pair shielded
cable to the rear solder lugs of a wall plate fitted with
two RCA jacks on its front. Terminate the shield at the
Right negative (-) or Left negative (-) ring of the solder
lugs. RCA cables can be used to connect the amp or sub-
woofer to the wall place for audio signal feed.
3 Speaker Output Connector for Speakers
The Speaker Output connections provide speaker-level
audio output for a pair of 8-ohm speakers. The screw-
down terminals accepts up to 16 gauge speaker wire.
4 Status Jumper for Status LED Enable/Disable
The Status option provides visual indication when source
equipment is powered on. With this option enabled, the
status LED shows green on the keypad when the system
is on (keypad can be on or off).
To enable the Status LED, locate the status pins on the
right side of the keypad under the faceplate. Place the
status jumper over the bottom two pins to enable the
status LED.
Note: Amplified keypads are shipped with the Status LED
option disabled (default).
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 interfaces connected to the controller
(green LED off).
