Basic application

Crossover frequency control checklist:

These sub bass amplifiers can be used in any of the bi-amplification systems described in

LOW PASS: 40Hz to 150Hz

this manual, replacing the 2 channel amplifiers as per the illustrations.

SUBSONIC:15 Hz to 55 Hz
BASS EQ: 0 to +9dB

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.

Level control checklist:
Refer to the section “Setting up systems after installation for best performance”

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

Minimum final loudspeaker impedance:

which have multiple positive and negative connections for ease of wiring. The 2 positives

P1-1050.1 = 2-Ohms

are the same internally and the 2 negatives are the same internally.

P1-2050.1 & P1-3050.1 = 1-Ohm
