The AB 2 keypad is operated using “long” and “short” button presses to activate different commands using the same button. A short press is released quickly. For a long press, continue to hold the button for about three seconds before releasing it.

For more sophisticated control, aim a properly programmed remote control, such as the second-zone remote included with an A-BUS-equipped Harman Kardon receiver, at the IR Receiver on the AB 1 or AB 2 (or other A-BUS module if so equipped), and control commands will be passed directly to the source device.

Volume Control

Volume is controlled locally for each room of each zone using its A-BUS module. On the AB 1, tap the Volume Down Button to temporarily mute the audio, and tap the Volume Up Button to restore audio. For the AB 2, each short press of the Power Off Button toggles between the muted and unmuted modes.

NOTE: When the system is turned off, all modules will reset to their minimum volume.

Powering the System Off

Press and hold the Power Button on an AB 2 to turn off the ABH 4000 and the entire system, if the Harman Kardon A-BUS-equipped receiver is in tuner mode. If another source is playing, the AVR will remain on – for example, if someone is watching a DVD in the main listening room. However, the ABH 4000 will turn off, which terminates the trigger signal and thus turns off any sources connected to the Trigger Output.

NOTES:

•If you wish to fully power down the system, select the tuner as the source just before pressing and holding the Off Button.

•If you only wish to power down the ABH 4000, make sure that any sources being used by others are not connected to the Trigger Output, or they will turn off.

LED Indicators

numbered Audio Input. The ABH 4000 will route signals from any output zone that has selected that source device directly to that device. This allows you to use two sources with the same control code set, such as two CD players, with control commands affecting only the desired device.

Use the Common IR Output when all devices use independent code sets to simplify control through a receiver or other central component. All control commands received from all zones are output through the single Common IR Output. Connect it to a receiver’s IR input, or connect an IR emitter that is placed over the receiver’s IR sensor, as shown in Figure 3.

Optional Step Five: System Expansion

See Optional Step Four in the Connections to an A-BUS-Equipped Product section, to expand the system using additional hubs.

NOTE: The following steps provide additional options that extend the flexibility of your A-BUS system. If you are not familiar with audio/video systems installations, you may wish to have them completed by a properly trained installer.

Optional Step Six: Trigger Connection

Connect the Trigger Output to a component or power relay that turns on in response to a steady-state 12-volt trigger signal. When the ABH 4000 hub is turned on, the trigger signal will turn on any components connected to the Trigger Output, or components that are plugged into a power strip connected to the Trigger Output. When the ABH 4000 is turned off, the components will also turn off.

Optional Step Seven: Connect IR Emitters

If you are not using direct IR control connections to “IR In” jacks on non-A-BUS products and wish to control a source product, connect an optional IR emitter to the Routed or Common IR Outputs and place it over the IR sensor on the front panel of the unit to be controlled.

Operation

There are no user controls on the ABH 4000; it is controlled using an AB 2 keypad or the remote suppled with the AB 2.

After checking the connections, plug the AC power cord from the ABH 4000’s Power Supply A into a non-switched AC outlet. If modules have been connected to Bank B for any zone, a second power supply (sold separately) is required and must be plugged into Power Supply B and a second non-switched AC outlet. The power supply is designed specifically for use with the ABH 4000. Do not substitute another power supply.

When the ABH 4000 is used with an A-BUS-equipped product, the A-BUS modules in the remote room operate as if they were connected directly to the host receiver. No further controls are needed. Follow the instructions included with the A-BUS modules for operation information.

When the multiroom system of a Harman Kardon A-BUS-equipped product is turned on or when a source is selected from one of the zones, the ABH 4000 will also be activated.

When a non-A-BUS source is used, the ABH 4000 turns on when a source is selected from one of the zones.

The Status Indicator will light, and the Trigger Output will activate, signaling any devices connected to it to turn on as well.

Use the second-zone remote included with an A-BUS-equipped product to operate the sources and the system, as described in the product’s manual. For simple functions, when an AB 2 keypad is installed, it may be used to operate the sources and system as described below. The ABR remote included with the AB 2 may also be used, as described in the Function Table.

Source Selection

When an AB 2 is present or using the ABR remote, press any of its four source buttons to select that source. If the AB 2 and the ABH 4000 are turned off, they will turn on, and if the source is connected to the Trigger Output, it will be activated and play will begin. The AB 2’s power indicator LED will light to indicate that the system is turned on, and the LED indicator for the selected source will light on the AB 2.

The three LED indicators on the ABH 4000 signify the following operational modes:

•The Status Indicator lights when the system is activated either by connection to an A-BUS-equipped product that is turned on, when a source is selected, or when the system is turned on from a remote zone. This light also indicates that the Trigger Output is active.

•The Power Indicators light when an AC Power Supply is connected to either power input on the ABH 4000 (for Bank A or B) and/or when a connection is made between the ABH 4000 and an A-BUS-equipped product. This light does not indicate that the system is powered on; that is indicated by the Status Indicator.

•The IR Talk Indicator flashes whenever an IR command is transmitted through the system.

Troubleshooting Guide

If the remote A-BUS modules do not operate at all:

•Verify all connections between the remote modules and the ABH 4000.

•Check the RJ-45 connection between the ABH 4000 and the host product.

•Check the AC power connection at both the ABH 4000’s Power Jacks and on the Power Supplies.

If the remote module’s status LED is lit but there is no sound:

•Make certain that an active source has been selected on the host receiver.

•Check the RJ-45 connection between the ABH 4000 and the A-BUS- equipped host product.

•Check the audio connections between the ABH 4000 and the non-A-BUS host product.

•When the ABH 4000 remote or the AB 2 keypad is in use and the CD player or The Bridge has been selected, repeat the command, as it issues Play and Pause and depends on the current status of the source.

ABH 4000

To select The Bridge as the source on an A-BUS-equipped Harman Kardon product when The Bridge is connected, press and hold the AVR Button on the AB 2, or press the appropriate source selector on the second-zone remote included with the AVR.

NOTES:

•The functions selecting The Bridge or a CD player as the source issue the Play/Pause command. However, the source’s status is not communicated back to the AB 2, which always issues the same command when the button is pressed. If the source is selected and no audio is heard, press the button again.

•Some older CD players and other source devices require separate commands for the Play and Pause functions. These devices may not operate as described when connected to Source 2.

•It is preferable to connect all of the sources to an A-BUS-equipped Harman Kardon product, and select and operate them using the second-zone remote included with the product.

Source Control

If the source is an A-BUS-equipped product, or if it is connected to the Routed or Common IR Outputs using either a wired connection or an IR emitter, the AB 2 or its remote will provide simple control functions as described in the table above,
