AT-101
WARNING: Improper installation could result in damage to the
amplifier. Read all instructions before installation.
Introduction
The Jamo AT-101 Audio Stereo Attenuator with automatch can be
used as a volume control for up to 64 pairs of speakers.
PLACEMENT
The AT-101 should not be located close to light switches/dimmers
as this may cause a hum in the speakers. If the AT-101 is located
close to these devices it must be mounted in a separatly grounded
electrical box. Speaker cables/wires should also be as far away from
electrical wires as possible.
INSTALLATION
The amplifier must be turned OFF before you install the AT-101 and/
or speakers or it may cause damage to the amplifier.
When connecting speaker cables/wires from the amplifier to the
AT-101 and from the AT-101 to the speakers make sure LEFT (L) is
connected to LEFT (L), RIGHT (R) to RIGHT (R), POSITIVE (+) to POSITIVE (+) and NEGATIVE (-) to NEGATIVE (-). If terminals are colour
coded, RED is POSITIVE (+) and BLACK is NEGATIVE (-). For installation of more than 1 pair of speakers see „Impedance matching“.
SET-UP
Before turning on the amplifier turn the amplifier volume to minimum. Turn the AT-101(s) to maximum volume (clockwise). Turn the
amplifier on and slowly turn up the volume to the highest desired
level without distortion from the speakers.
The volume of all speakers are now controlled by the AT-101(s) and
the amplifier volume control should not be used.
