HS300.4 / HS500.4 / HS800.4 4-CHANNEL AMPLIFIER APPLICATIONS
Front/Rear high pass, using a mono amplifier for mono sub bass
The combination of a 1 and a 4 channel amplifier, utilizing their built in
Channels 3/4: crossovers, makes it a snap to put together a full system with front and rear
highs, with mono sub bass.
- HI PASS: 100 Hz
- LOW PASS: N/A
Interconnect cable checklist:
- Using good quality RCA cables, feed the front and rear outputs of a head unit to
2 channel bass amplifier:
the inputs of the 4 channel amplifier as shown. - Subsonic filter: 10 Hz to 40 Hz
- Also connect the LINE OUT of the 4 channel amplifier to the LINE INPUT of the - LOW PASS: 80 Hz
1 channel amplifier as shown.
Please note that these frequency points are suggestions only. Refer to the
Mono bass woofer wiring: loudspeaker manufacturer specifications and the section “Setting up systems
Connect the mono speaker positive terminal to the either +, and its negative after installation for best performance”
terminal to either -.
