4Ch 2-Way Mode
With the unique features of the Z-Series amplifiers you can also use the Z-150.4 II
to drive a 2-way system with the front channels for highs and the fear channels for
lows. The unique crossover will let you separate high and low like most 4Ch amps,
but with the added range provided by the multiplier (x10) switch you can actually
have a tweeter crossover as high as 5,000Hz on the front channels. With the series'
band-pass functions, you can have the rears play everything below the tweeters,
or you can have the rears play only midrange and use a separate amp for your
subs.
For the diagram below of an active 2-way system:
• Front (1/2) crossover is set to HPF and multiplier switch set to x10 (in).
HP frequency is set to the tweeter's recommended cut-off point (usually
between 2KHz and 5KHz)
• Set the rear filter to LPF/BPF so both the rear filters are active
• Set the LPF/BPF multiplier switch to x10 (in) and set the frequency to the
same frequency that was used on the tweeter high-pass filter
• If the lows speaker will be used as woofers then set the rear (3/4) HPF to
around 30Hz as a sub sonic filter
• If another amp will be used for bass and channels 3/4 will be used a midrange,
then set the rear HP filter to the frequency where the woofer will begin
operating (usually 80Hz~120Hz)
