A2 AMP | OWNER’S MANUAL
Please read the following instructions carefully before installing your Induction Dynamics
®
A2 amplifier. If you have any questions
regarding installation that are not answered in the following directions, please contact your local sound contractor or the

Subwoofer Amplifier Interconnect
The ID1 series and SW series is designed to be used with the A2 subwoofer amplifier (designed and built by Induction
Dynamics
®
). The A2 subwoofer amplifier is designed to integrate with audio/video pre-amplifiers and receivers that have
their own built-in low-frequency crossover circuits, typically containing optional crossover frequency settings. If the crossover
frequency is selectable, the recommended setting to use is 80 Hz with the subwoofer connected in reverse polarity (see below
under Subwoofer Connection).
Using high quality interconnect cables with RCA type terminations, connect “SUBWOOFER OUT” on the audio/video pre-
amplifier or receiver to “IN” on the A2. You may adjust the subwoofer level using the control in the menu of the audio/video
pre-amplifier or receiver.
Subwoofer Connection
The jumpers should be removed and the switch set to “Three-way + Subwoofer”. Connect the lower binding posts on the
back of the speaker to the A2 subwoofer amplifier in series using reverse polarity (red to black and black to red). Please see the
diagrams showing alternative methods of connecting the subwoofers, to achieve the in-series, reverse-polarity connections.
Power Connection
Connect the A2 amplifier to a 120 volt, single phase, 60 Hz, grounded power supply using the power cord provided. For best
results, use a dedicated power circuit for your amplification equipment.
