3) The input sensitivity of the two amplifiers
needs to be adjusted independently. To
properly calibrate the amplifiers for
maximum, identical, clean output, please
refer to Appendix A (page 14). After using this
procedure, you can then adjust the level of the
amplifiers by adjusting the input sensitivities
downward, if the amplifiers require attenuation
to achieve the desired system balance. If the
input sensitivities are adjusted, the amplifiers
must be recalibrated to ensure identical power
output levels.

APPENDIX D:
Master/Slave Configurations
With the flexible on-board crossovers and
processing incorporated into the 500/1v2, it
is possible to connect multiple 500/1v2’s in a
i.BTUFS4MBWFwDPOGJHVSBUJPOXJUIFBDIBNQMJGJFS
driving its own speaker system but controlled by
the processing and filtering of only one amplifier.
This is very useful when driving multiple
subwoofers with multiple amplifiers.
To create a Master/Slave configuration, first
