Product Overview

The AB-1.2 and AB-2.2 are dual-source selector

switches that allow a single pair of speakers to be

driven by either of two amplifiers or allow a single

amplifier to drive either of two pair of speakers.

The AB-1.2 and AB-2.2 are well-suited for situa-

tions where a local source such as a TV or amp

shares a pair of speakers with the whole-house

sound distribution system. The AB-1.2 and

AB-2.2 can also be used in settings where one

system powers two pair of speakers, each pair

located in a different area.

The AB-1.2 is a single-gang in-wall unit and the

AB-2.2 is a tabletop unit. Each unit has a push-on,

push-off button to switch between dual amplifiers

or dual speaker pairs.

Connection Instructions

1. Strip about 1/4” of insulation from the ends

of all wires to be connected to the unit. If

necessary, twist the exposed strands to

insure that no loose strands exist.

2. Refer to the three connection diagrams on

the reverse side for connection

configurations.

Figures 1-3 depict three connection scenarios

using the AB-1.2 and AB-2.2.

Figure 1: Shows how to connect two

amp/receivers and one pair of

speakers to the AB-1.2.

Figure 2: Shows how to connect one

amp/receiver and two pair of speakers

to the AB-1.2.

Figure 3: Shows how to connect one local

amp/receiver, one multi-zone audio

distribution amp and one pair of local

speakers to the AB-2.2.

NOTE: The AB-1.2 and AB-2.2 function in the

same way. Either unit can be used in these config-

urations, depending on if a wall-mount (AB-1.2) or

shelf-mount (AB-2.2) style is desired.
