REF1.800

Mono Amplifiers

FEATURES:

-1 Set of RCA inputs

-LEVEL: Variable sensitivity from 0.2V to 5V

-BASS EQ: Adjustable 45Hz bass boost from 0dB to 12dB

-SUBSONIC: Variable from 15Hz to 55Hz

-LOW PASS: Variable from 40Hz to 150Hz

Interconnect cable checklist:

Connect the inputs to a suitable source, e.g. a head unit with good quality RCA cables.

Use at least #12 gauge speaker wiring. The amps have dual speaker terminals, simplifying the hookup of multiple speakers. These amps are mono, 1 channel, amplifiers which have multiple positive and negative connections for ease of wiring. The 2 positives are the same internally and the 2 negatives are the same internally.
