full range units.
- LOW PASS: N/A
Interconnect cable checklist:
- Connect the four inputs of the amplifier to a Radio/CD with quality RCA cables.
Level control checklist:
- Refer to the section “Setting up systems after installation for best performance”
Switch setting checklist:
Minimum final loudspeaker impedances:

- Connect the inputs of channel pair 1/2 to a suitable stereo source, e.g. a head unit
with good quality RCA cables.
TIP: If you are using the mono sub bass output of an active crossover, there is nothing

wrong with switching in the low pass filter in these amplifiers for a steeper low pass
available from the mono sub bass output of an active crossover, whether standalone,
rolloff.
