A One-Amp, Active 3-way System

The Z-150.6 II 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-passes 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)

• Ch 3/4 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 Ch 3/4 LP frequency is set to

the same frequency as the tweeter HP frequency (usually 2kHz~3kHz) that

was set in the previous step

• Ch 5/6 are bridged for a mono woofer. Ch 5/6 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
