M1500.1D / M2500.1D / M4000.1D MONO AMPLIFIER APPLICATION
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. 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.
