PUNCH BASS (Model 700X Only)
1. Turn clockwise to add Punch to amplifier bass frequencies.
CAUTION: Overexcursion may occur at maximum boost, which may cause
damage to the woofer.
Do the following individually for each channel.
To adjust the gain setting, turn the amplifier gains all the way down. Turn the source unit volume up
until distortion is audible and then turn it down a bit until the distortion is inaudible. This will be
about two thirds all the way up on most source units. Next, turn the amplifier gain setting until once
again distortion is audible and then back it down until the distortion is inaudible. Rockford Fosgate
source units do not distort, so the volume can be used at maximum setting.
NOTE: For a more in depth setting procedure, contact Rockford Technical Support.
