35 effects send
Output for supplying signal to an external low-level effects or signal processing unit.
36 effects mix
Since the effects loop on the ProBass 500 is a side-chain effects loop‚ the mix between the dry (unaffected) and wet (effects)
signal can be adjusted with this control. When the control is fully CCW‚ there will be no effects present (dry). When the
control is fully CW‚ the effects loop is fully wet. This same mix is set to the post EQ XLR as well as the main preamp out.
37 line out ground lift switch
Provides ground to be made from the line out jack or lifted to eliminate ground loops from the ProBass 500 and external
source(s). There may be some rooms or situations when audible hum and/or noise is present. Minimizing this noise may
be possible by depressing this switch.
38 select switch
Allows selection of a pre EQ or post EQ send to the low Z balanced line out jack. The "out" position selects pre EQ and
the "in" position selects post EQ line out.
39 line out (low Z balanced)
An XLR jack is provided to route the signal to a mixing console or recording equipment. This output can be selected for
pre EQ or post EQ operation.
40 line out level control
Controls the output level of the balanced line level output.
41 tuner send jack
This 1/4" jack is provided for connecting an instrument tuner to your amp. Its signal is buffered off the input jack so it is
just like plugging directly into the tuner.
42 auxiliary input jack
This 1/4" jack is provided for connecting an instrument to the amp from behind the rack. It is just like plugging directly into
the front panel input jack. Note that the front panel input jack overrides the rear panel input jack. This means that if you are
using the rear panel input jack and then plug another instrument into the front panel‚ the rear panel input will be defeated.
