AutoTek AT-Series, AT1200 AT2000.1 / AT3000.1 / Mono Amplifier Applications, Adaptor, Not Used

AT2000.1 / AT3000.1 / MONO AMPLIFIER APPLICATIONS

Basic application

These sub bass amplifiers can be used in any of the bi-amplification systems described in this manual, replacing the 2 channel amplifiers as per the illustrations.

Interconnect cable checklist:

Connect the inputs to a suitable source, e.g. a head unit with good quality RCA cables. Connect the LINE OUT to the inputs of the system highs amplifier.

Use at least #12 gauge speaker wiring. The amps have dual speaker terminals, simplifying the hookup of multiple speakers

Crossover frequency control checklist:

LOW PASS: 35Hz to 250Hz
