High Power 2-way System
The system below provides plenty of power for a 2-way active system with even the
lowest efficiency front speaker system. Each speaker has 550 watts RMS @ 4Ω
• Since all speakers are being bridged, they must all be minimum 4Ω~8Ω impedance
• Ch1/2 and 3/4 will use Filters set to HPF with frequency set to where the woofer will
begin
• Ch5/6 will use the HP Sub Sonic filter at 15Hz
~
30Hz to protect the woofer. The
low- pass filter should be set the HP frequency of the full-range speakers on Ch1/2
and Ch3/4
It is critical the crossover frequencies and gains of Ch1/2 and Ch3/4 are set exactly the
same.
This same setup can also be used for a high power Left, Center, Right front stage.

A One-Amp, Active 3-way System
The Z-150.6 SP is a superbly versatile piece of gear. With the crossover features of this amp
you can run a completely active 3-way system. You can run it as Tweeter, midrange, bass.
You can also ruin it as tweeter, band-passed mid-range, and band passed mid-bass and then
use a separate subwoofer amp. Below is an active 3-way system using a mono bass driver.
• The Input Mode switch can be set for 2,4,or 6 channels of input, but setting up a
3-way system is best done with a 2-channel input unless you are using a digital
processor ahead of the amp
• Ch1/2 are used for tweeters. The multiplier is set to x10 (pushed in) with the Filter
switch set to HPF. The HP frequency is set to tweeter's recommended HP range
(usually between 2kHz~3kHz)
• Ch3/4 are mid-range. The Ch3/4 Filter switch is set to LPF/BPF so both filters are
active. The HP frequency should be set to the frequency that the woofer will begin
(usually between 80Hz~120Hz). The Ch3/4 LP frequency is set to the same frequency
as the tweeter HP frequency (usually 2kHz~3kHz) that was set in the previous step
• Ch5/6 are bridged for a mono woofer. Ch5/6 always have both filters active.
Set the LPF frequency to the same frequency as the Ch3/4 high pass filter, so the top
of the woofer is the bottom of the midrange
• The bass boost should only be set after system is installed and you have had a
chance to listen to see if any bass boost is needed
Speakers on channels 1~4 must be minimum 2Ω of higher. The bridged woofer must be 4Ω of higher.
You can add the optional dash control for the bass channels 5/6
