JAMO MANNO33, 2C+AT1A User Manual


WARNING: Improper installation could result in damage to the amplifier. Read all instructions before installation.


The Jamo AT-1A Volume control can be used as a volume control for one pair of speakers.


The AT-1A should not be located close to light switches/dimmers as this may cause a hum in the speakers. If the AT-1A 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.


The amplifier must be turned OFF before you install the AT-1A and/ or speakers or it may cause damage to the amplifier.

Connect the speaker output on the receiver/amplifier to the INPUT on the AT-1A. Connect the OUTPUT from the AT-1A to the left and right speakers

When connecting speaker cables/wires from the amplifier to the AT-1A and from the AT-1A 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 (-).


Before turning on the amplifier turn the amplifier volume to minimum. Turn the AT-1A 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 the speakers are now controlled by the AT-1A and the amplifier volume control should not be used.
