Operation
1.
Make sure the power is OFF on the amplifier(s) or receiv-
er(s) and set the volume(s) to minimum.
2.
If you are using a Niles speaker selection system in con-
junction with the ABA-1D, locate the ON/OFF button which
corresponds to the ABA-1D. Set it to the ON position.
3.
Turn on the amplifier(s) or receiver(s) and select a source,
such as the tuner or CD player.
4.
Using the A-B selector button on the ABA-1D, select the
speaker pair (or amplifier) you wish to play.
5.
Slowly turn up the amplifier or receiver volume and set it
to a comfortable (not maximum) listening level. Be careful
not to overdrive or "clip" your amplifier. If the sound
becomes muddy or distorted, you have reached the limit of
your amplifier's volume capability and should quickly reduce
the volume to avoid damaging your speakers.
Note:
If the speaker pairs connected to the ABA-1D are
equipped with Niles volume controls, adjust the volume of
the speakers to the desired listening level using the Niles con-
trols. If all the speaker pairs in your system are equipped with
Niles volume controls, you can leave the amplifier or receiver
volume(s) set at one position and use the Niles controls
exclusively.
6.
You can select either speaker pair (or amplifier) by simply
pressing the A-B button on the ABA-1D.
