Z-150.6 SP Input Ends
The Z-150.6 SP is the 6-Channel SP amp and it also has the same basic controls and
features as the other amps but has been adapted for 6-channel use.
• The channels 1/2 do not have a low-pass filter as they will be used either full range
or for mids/highs so there is only high pass here
• Ch. 3/4 have high pass, full range, and low pass positions so they can be used for
highs, or they can be band-passed for mid-range use
• Ch. 5/6 do not have a crossover function switch as they are band pass only. They
can be used as the bass section with the low-pass and a variable subsonic. The sub
sonic (which is high-pass), however has a wide frequency range so it can be used as
the bottom of a band-pass to drive mid-bass drivers, if you have a separate sub amp
• The input mode switch lets you use 2Ch, 4Ch, or 6Ch of input, so you can drive all
the channels from a single 2Ch stereo output from a head unit
* See explanations in Z-150.2P #1

Z-150.4 SP Input Ends
The Z-150.4 SP is the 4Ch amp and has the same basic controls and features as the 2Ch
amps but adapted for 4-channel use.
• The front channels do not have a low pass filter as they will be used either full range
or for mids/highs or even tweeters
• The rear channels have exactly the same controls as the 2-Channel amps as the
rears will be used as full-range or bass, depending on the application, or even
band-pass if the amp is used for tweeters (Ch1/2) and mid-range's (Ch3/4)
* See explanations of these functions on the previous section 2-Channel amps #1,3,5,7
