Operation
1. Make sure the amplifier or receiver power is OFF and set
the volume to minimum.
2. Set both selector buttons on the AB-2D to the OFF posi-
tion (buttons out).
3. If you are using a Niles speaker selection system in con-
junction with the AB-2D, locate the ON/OFF button which
corresponds to the AB-2D. Set it to the ON position.
4. Turn on the amplifier or receiver and select a source, such
as the tuner or CD player.
5. Using the selector buttons on the AB-2D, select the speak-
er pairs you wish to play.
6. 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 AB-2D are
equipped with Niles volume controls, adjust the volume of the
speakers to the desired listening level using the Niles controls.
If all the speaker pairs in your system are equipped with Niles
volume controls, you can leave the amplifier or receiver vol-
ume set at one position and use the Niles controls exclusively.
7. You can turn off the speakers by simply pressing the
ON/OFF buttons on the AB-2D you wish to play.
