Russound A-KP2 2000-115905 Leaflet

Amplified Keypad Module for A-BUS

®

System

The A-KP2 is an in-wall, A-BUS

®

Amplified Keypad with push-but-

tons for speaker volume level and power On/Off source select as
well as an IR window for receiving remote control signals. The A-
KP2 connects to A-BUS

®

Hubs or A-BUS

®

Ready receivers using

CAT-5 wiring, and to loudspeakers using conventional speaker wire.

IMPORTANT – Before installation, review the manuals included
with each component in your system. If you are unsure of any of
the installation procedures described herein or elsewhere, consult a
professional electronics installer.

1) Power On/Off source select button

2) Volume Up/Down buttons

3) Built-in IR receiver

4) IR control of volume and On/Off source select via optional 

A-LRC1 remote

5) IR control of source components in an A-BUS

®

system that 

uses IR Emitters

6) LED indicator for IR confirmation and source component 

on/off status

7) Volume Trims for setting max. allowable level and L/R balance

8) Line Out for connecting to external amp or powered subwoofer

9) Decora® faceplate

• Power On/Off source select and volume level can be controlled

using the buttons on the A-KP2 or by using the optional A-LRC1
remote control. The A-KP2 will always reset to a low volume level
when turned on.

• If you have installed IR Emitters in your A-BUS

®

system, then

sources can be operated with their own remote (or a “universal”
remote) by aiming it at the IR window on the A-KP2.

• When the A-KP2 receives infrared signals from a remote control,

the LED indicator will flash red.

• If your are using the STATUS feature in your A-BUS

®

system, the

LED indicator on the A-KP2 will illuminate green when your source
equipment is on, even when the A-KP2 is off.

Check all connections and test the system’s operation before installing
the A-KP2 into the wall. Using the included hardware, install the A-KP2
into a standard UL/CSA approved electrical J-Box as shown.

Two rotary trim potentiometers are located on the back of the A-KP2.
These can be used to set the maximum allowable volume level and to
adjust left/right balance. Use a Phillips-head screwdriver.

A CAT-5 cable is used to connect the A-KP2 to a keypad output on
an A-BUS

®

Hub or A-BUS

®

Ready receiver. For clean installations,

use RJ45 CAT-5 patch cables to connect from the Hub to an RJ45
Wall Plate (optional), and then wire from the Wall Plate to the
Amplified Control Module (see diagram). The Amplified Control
Modules have 110 punchdown connectors for the 8 individual con-
ductors of the CAT-5 cable (use a punchdown tool with a 110 blade
to insert conductors). 

NOTE: When wiring directly to an Amplified Control Module (i.e.,
not using an RJ45 Wall Plate) use T568A RJ45 wire configuration
for connection to the hub.

The STATUS jumper is located on the underside of the A-KP2. All
A-BUS

®

components are shipped with the STATUS feature disabled.

If you intend to use the STATUS feature with your A-BUS

®

system,

you must enable the STATUS jumper on every Amplified Control
Module as well as on the A-BUS

®

Hub.

Connect speaker wires to the speaker output terminals on the A-KP2
as shown in the diagram. The A-KP2 is designed for one pair of 
8 Ohm speakers.

An external amplifier can be connected to the LINE OUT of the 
A-KP2 to provide more power in a large listening area, such as an
outdoor patio. The LINE OUT can also be used to feed a powered
subwoofer for extended bass response. This output is variably con-
trolled by A-KP2 volume.

CAT-5 CONNECTIONS

• Before connecting the A-KP2:

- Make sure that the A-PS power supply is not connected to the
A-BUS

®

Hub or, if you are using an A-BUS

®

Ready receiver, that

the receiver is off. 

- Make sure that the STATUS input on the A-BUS

®

Hub is not

connected.

• The recommended maximum length for use with standard

CAT-5 cable is 250 feet.

• Once all of the connections have been made, the A-PS power

supply can be connected to the A-BUS

®

Hub or, if you are using

an A-BUS

®

Ready receiver, the receiver may be turned on.

• Make any Volume Trim adjustments on the A-KP2 before

installing it into the wall.

OPERATION

The Multi-Source Mode Switch should be set to Single-Source when
using the A-KP2 with Single-Source A-BUS

®

hubs. The Switch should

be set to Multi-Source when using the A-KP2 with Multi-Source 
A-BUS

®

hubs.

MULTI-SOURCE MODE SWITCH

Source Selection:

• Tapping the power button will allow you to toggle between multiple

sources once the initial press for power “on” is performed. The top 4
LEDs of the volume indicator will show the source that is selected.

Zone (Keypad) Off:

• Press and hold the power button until the keypad turns off.

System (Hub) Off:

• When the keypad is off, press and hold the power button until the

Green LED blinks Red and turns off.

Other Functions:

• Source selection and all other functions of the A-KP2 can be made

using the A-LRC1 hand-held remote.

MOUNTING

The product you have just purchased is an integral part of the Russound

®

A-BUS

®

Multi-Room Audio System. It is a component which, when combined

with other essential components and your source equipment (receiver, CD play-
er, etc.), creates a versatile whole-house audio system that will fill your rooms
with high-quality sound for years to come.

A-BUS

®

technology is a new, innovative method of providing high quality audio

to remote locations with a single 8-conductor cable such as CAT-5. 
A-BUS

®

technology provides many advantages over other methods of audio

distribution, including: simple, single CAT-5 wiring scheme; infrared control of
system components; infrared control of the optional A-KP2 amplified keypad
module; and system power status.

Every A-BUS

®

System is comprised of components from each of the following

three areas. 

1. A-BUS

Amplified Control Modules: The Module contains both the ampli-

fier for the room’s speakers as well as the control for those speakers. One
Module should be used for each room you choose to control. The
Russound

A-KP2 Amplified Keypad (with built-in IR receiver) and A-VC

Amplified Volume Control are examples of A-BUS

Amplified Control

Modules.

2. A-BUS

Hubs: All components of the A-BUS

system must be wired cen-

trally to a Hub located near your source equipment. The Hub provides the
connection for source equipment, volume controls, infrared emitters and
power supply. The A-H484, A-H4, A-H4D, and A-H2 are examples of 
A-BUS

Hubs. The A-H484, A-H4, and A-H2 are surface-mount units. 

The A-H4D is an in-wall Decora® style unit.

3. Power Supply: The power supply plugs into the Hub. The Russound

A-PS 24VDC/2.5A unit is an example.
