You can connect an active or a passive bass to this ¼” input
jack. The RH750 input stage is designed to adapt to any type of
pickup.

The input gain should be set to the highest possible level without
overloading the input stage. To find the correct setting, simply
pluginyourbass,playandturnuptheGAINknobuntilthe
OVERLOAD LED occasionally lights up. Then reduce the gain
slightly. When set, simply turn up the MASTER volume knob to
start playing.
4 – TONE Controls
RH750 has four tone controls: Bass, Lo-mid, Hi-mid and Treble.
These controls have been tuned carefully to address four
relevant bass frequency areas, and should allow you to dial in
your sound with ease.
As you know, each instrument has its own sound characteristics.
If you feel that your RH750’s tone controls don’t grab exactly the
frequencies your particular instrument requires, you can change
thecenterfrequenciesofthefourEQbands.
Changing Tone Control Frequency
You can change the control frequencies of all four frequency
bands. This is sometimes referred to as “parametric bands” or
“sweepable”.
Normally, the BASS, LO-MID, HI-MID and TREBLE knobs are
used to set the gainofeachEQband.Tochangethecenter
