A Dual Mono Drive system is a system in which 2 monaural amplifiers are
both set to bridged mode to drive one subwoofer with a high-output signal.
Setting
1. If you use the connection as shown, set amplifier
¡ to the Forward phase
(PHASE: 0 º) and set amplifier
™ to the Reverse phase (PHASE: 180 º).
2. Set all other switches (except for the "PHASE" switch) of amplifiers
¡ and ™ to
the same position.
Connection
1. Connect the
9 speaker wire to the 9 terminal of amplifier ¡. Also, connect
the
· speaker wire to the 9 terminal of amplifier ™.
2. Connect between
· terminals of amplifiers ¡ and ™.
3. The remote controller can be used just when connected to amplifier
¡. It can
be used for more fine control if also connected to amplifier
™.
2CAUTION
• Always connect between
· terminals of amplifiers ¡ and ™. If a cable is
incorrectly connected between
9 and · terminals of these amplifiers, the
amplifier protection circuit is turned on.
• Use a speaker having the 2Ω or higher impedance only.
• To protect the electrical system from a short-circuiting, be sure to remove the
· battery cable from the vehicle in advance.
• Fully insulate amplifier terminals and speaker terminals to avoid a high voltage
from peripherals.
