Figure 1
To connect two amp/receivers and one pair of
speakers:
1. Connect the first amp/receiver speaker output to
the Amp A input of the AB-1.2, keeping channel
and polarity consistent.
2. Connect the second amp/receiver speaker output
to the Amp B input of the AB-1.2, keeping
channel and polarity terminations consistent.
3. Connect the speaker pair to the speaker output of
the AB-1.2, keeping channel and polarity
terminations consistent.
To connect one amp/receiver and two pair of speak-
ers:
1. Take leads from the amp/receiver speaker output,
and connect to the speaker output of the AB-1.2,
keeping channel and polarity terminations
consistent.
2. Connect one pair of speakers to the Amp A
input, keeping channel and polarity terminations
consistent. Connect the second pair of speakers
to the Amp B input, keeping channel and
polarity terminations consistent.
Figure 3
To connect one amp/receiver, one multi-zone audio distribution amp and one pair of local
speakers:
1. Connect wires from the amp/receiver speaker output to the Amp A input keeping the
channels and polarity consistent.
2. It is recommended to connect a Russound UltraMatch™ impedance matching volume
control such as the ALTx in between the multi-zone amp and the AB-2.2.
3. Connect the wires from the multi-zone amplifier speaker output (for the desired zone) to
the input connection on the ALTx. Then run wires from the ALTx output to the AMP B
input on the AB-2.2, keeping channel and polarity terminations consistent.
4. Connect the local speaker pair to the speaker connection on the AB-2.2, keeping channel
and polarity terminations consistent.
