Z-150.4 Sp Input Ends - zapco Z-150.2 SP Owner's Manual

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).
• The Z-150.4 SP adds a 2Ch/4Ch switch so you can choose to have only the
Ch1/2 inputs feed both front and rear
