User manual HARMAN KARDON AB 2

[. . . ] With your purchase of a new AB 2 Amplified In-Wall Module you will be able to extend the flexibility of your home entertainment system so that it delivers sound to another room in your home. Custom-designed for use exclusively with Harman Kardon A-BUS® -equipped products and ABH series hubs, the AB 2 enables you to send a separate source to the remote room and power most speakers ­ without the need for an additional amplifier ­ through one single Category 5/5e cable. The keypad and built-in IR sensor, compatible with the included remote and Harman Kardon AVR and second-zone remotes, offer control over source selection and operation, local volume and system power. To fully enjoy the benefits of remote keypad control, please take a few minutes to read this owner's manual. [. . . ] MP3 Source Control ­ When the AB 2 is used with a Harman Kardon ABH 4000 or other compatible multizone A-BUS hub, and when an MP3 player is connected to Source 4 of the hub, tap or press and hold this button to select the MP3 player as the source. Muting the AB 2 does not affect the source device, which will continue playing. If the AVR's tuner or The Bridge is the current source, or if the AB 2 is connected directly to the AVR, press and hold this button to turn off the AVR's multiroom system. If any other source has been selected and the AB 2 has been connected to a hub, press and hold this button to power off the hub. Skip Up/Down ­ Tap this button to skip up, and press and hold it to skip down. The precise behavior depends on the current source: · AVR Tuner: Preset up or down; no effect on The Bridge · CD: Track skip up or down (Harman Kardon players only) · DVD: Next or previous chapter (Harman Kardon players only) · MP3: No effect NOTE: When the AB 2 is connected directly to a Harman Kardon AVR, you may control sources connected to the AVR by pointing the AVR's or source's remote at the AB 2's IR sensor. Input-Cable Connection Block ­ Using standard IDC punchdown tools, connect the Category 5/5e cable linking the AB 2 to the receiver or hub to this connection block in accordance with the color code printed on the circuit board. Output-Level Trims ­ Use these trim pots prior to final installation to match the output level of the AB 2 to your speakers. Speaker-Terminal Block ­ The wire used to connect the AB 2 to your speakers is connected to this terminal block. Insert the wire in accordance with the color coding shown and then tighten the screw. The maximum wire size is 14 AWG. Installation and Connection IMPORTANT SAFETY NOTES: · Before beginning the installation process, make certain that all electronic products in the system are turned off and disconnected from their A/V power connection. This avoids the possibility of accidental activation, which could possibly damage the equipment or cause personal injury. · Be certain to observe all appropriate safety measures when installing any wiring, including, but not limited to, the use of eye protection when required, and attention to the required distances between low-voltage wiring and high-voltage AC mains wiring. Step One: Run a Category 5/5e cable from the receiver or hub location to the module. Run a splice-free Category 5/5e cable from the location where the AB 2 module will be installed to the location where the A-BUS-equipped product or hub is placed. Connect the wires using standard 110 Insulation Displacement Connector (IDC) tools and procedures. DO NOT use screwdrivers to insert the wire into the IDC connection points. Make certain that there are no shorts between any of the individual wires, as this may cause damage to the AB 2. From left to right, the connections are made as indicated in the figure below. Brown Brown and White Blue Blue and White Green Green and White Orange Orange and White Output-Level Trims until the output begins to clip. At this point, back the trim control down in the opposite direction until the clipping stops. This is the correct level for your specific A-BUSequipped product and the AB 2. Before proceeding further, lower the volume back to normal listening level. You may switch keypads to better reflect the source devices connected to the ABH 4000 or other multizone hub. [. . . ] · Wiring protocol: TIA wiring specification for 568A at the A-BUS-equipped product end. · Connection terminals: IDC type for Category 5/5e cable; screw terminal type for speaker connections. · Speaker wire: Maximum AWG 14, in compliance with any applicable local building code or NEC requirements for in-wall, riser or plenum use. · Speaker impedance: Suitable for connection to speakers with nominal 6 ohms to 8 ohms impedance.
