Z-150.4 II Input Ends
The Z-150.4 II is the 4-Channel amp and has the same basic controls and features as
the 2-Channel 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)
• The Z-150.4 II adds a 2Ch/4Ch switch so you can choose to have only the
Ch1/2 inputs feed both front and rear
* See explanations of these functions on the previous section 2-Channel amps
