HFi1000D / HFi1500D / HFi2000D / HFi2500D MONO AMPLIFIER APPLICATION
Basic application
These sub bass amplifiers can be used in any of the
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.
Crossover frequency control checklist:
LOW PASS: 35Hz to 250Hz
SUBSONIC:15 Hz to 35 Hz
BASS EQ: 0 to +10dB
Level control checklist:
Refer to the section “Setting up systems after installation for best performance”
Minimum final loudspeaker impedance: 1-Ohm.
