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

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).

6 Gain Control for Maximum Levels

The two rotary trim potentiometers on the side of the

A-K4 provide adjustment of audio gain. These are used to

set the maximum allowable volume for the left and right

speakers connected to the A-K4.

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 RJ-45 connector.

The Keypad Ports are located on the back of the A-C68 on

the left. Connections at the Keypad Ports are made with

RJ-45 connectors using T568A CAT-5 cable configuration.

CAT-5 cable length should be no longer than 150 feet

from controller to keypad.

If connecting A-K4 or A-K6L keypads to the A-C68, the

keypad dip switches on the front programming center

must be set in the DOWN position. For other A-BUS key-

pad connections, the dip switches must be set in the UP

position. Dip switch numbers correspond to the keypad

ports.

For a clean installation when wiring from a Keypad Port,

use an RJ-45 CAT-5 patch cable to connect from the key-

pad port to an RJ-45 wall plate (optional). Using the same

RJ-45 T568A CAT-5 wiring configuration, use CAT-5 from

the RJ-45 wall plate to the keypad.

8 Installation

Check all connections and test the system’s operation

before installing the A-K4 into the wall. Using the includ-

ed hardware, install the A-K4 into a standard UL/CSA

single-gang electrical J-box.

1 RJ-45 Connector for CAT-5 Connection

The RJ-45 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 maxi-

mum length for standard CAT-5 cable is 150 feet.

Before connecting the A-K4, 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 Ampli cation

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-K4.

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 Source Mode Jumper for Single/Multisource

The single/multisource jumpers set the A-K4 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.

5 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: Use caution when connecting speaker wires, as shorting between terminals will cause damage to the digital amplifier and

void the warranty.

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.
