Now connect the amplifi er to the ProRMP, play the dry track and adjust the
ProRMP's LEVEL control until the volume matches the direct guitar.
At this point, you have recorded a dry guitar track, inserted the ProRMP
between the mixer and amp and adjusted the LEVEL control to match your
guitar. You would now play the dry track into the ProRMP to drive the guitar
amp. The amp is mic'ed and recorded to another track. The process may be
repeated as long as you have tracks to record to and ideas to try out.
You are now set to go! Have fun! Experiment!
GROUNDING OPTIONS
The Radial ProRMP is equipped with a ground LIFT switch that lifts pin-1 on
the XLR INPUT jack. When the ground LIFT switch is depressed the ProRMP
derives its ground through the ¼" OUTPUT connector to the amplifi er's ground.
It is important that the ProRMP only be used with properly grounded amplifi ers.
USING THE ProRMP WITH GUITAR EFFECT PEDALS
You can use the ProRMP with guitar eff ect pedals. This is accomplished either
by driving the pedal through a guitar amplifi er or by sending the output of the
eff ect pedal to a direct box and then to the recorder. We recommend the Radial
ProDI for this application, because the isolation transformer in the ProDI will
help eliminate noise caused by ground loops.
USING THE ProRMP WITH KEYBOARDS
Keyboards may also enjoy the benefi ts of the ProRMP by following the same
procedures. There's no better way to turn a solo synthesizer track into a 'barn
burner' than to pass it through a distorted tube guitar amplifi er or tube distortion
pedal. Players like the legendary Jan Hammer used this trick to create those
amazing 'guitar' solo sounds. This is also a great way to get more 'growl' from
those 'clean' B3 sounds. Half the magic of a traditional Hammond comes from
the tube amp and Leslie being pushed to the limits. This is why Keith Emerson
also used distorted guitar amps to record and perform. Try mixing sounds
between clean and distorted keyboard tracks and have fun!
USING THE ProRMP WITH VOICE
Sometimes, vocals can be too clean and lack that 'seasoned' rough edge. By
driving a voice track through the ProRMP into a distortion pedal like the Radial
Tonebone Classic or through an overdriven amplifi er, one can introduce some
great eff ects. Double the clean track with distorted track and then mix them to
suit. A subtle extra edge is often all that is needed to warm up a stale track.
USING THE ProRMP WITH DRUMS
Re-amping sampled drum sounds can add realism. Snare drum is a mid-range
instrument and can sound great through a 4x12 guitar stack. For the kick drum
try a bass amp.
