Notes on the Mono Bass Amp controls:
• Strapping - Two Z-II mono bass amps can be bridged together to operate a
single voice coil (speaker) giving it roughly twice the power of a single
amplifier. When two amps are "strapped" the Master amps controls will
control crossover, sub sonic, bass boost etc. of both amps. When strapping
the amps you must maintain a minimum load of at least 2 Ohms
See the input wiring diagram Below:
The Master amp receives the input signal for both amps. With the switch in
"master", it sends the proper signal to the slave amp. The ONLY control used on
the slave amp is the master/slave switch which is put into the slave position.
These two amps will now act as one. See the next section for the speaker wiring.
• Sub Sonic - This filter is there to protect the woofer from frequencies that
can hurt it. Generally for large woofers in sealed boxes this can be set at
about 25 to 30 Hz. The sub sonic becomes most critical when used with a
ported box. The sub sonic should be set just below the port frequency
regardless of the woofer
• Phase - The phase control will help blend the woofer with the rest of the
system
