1 – INPUT
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.
2+3 – GAIN & OVERLOAD LED
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
frequency of an EQ band, press the SHIFT button once and then
adjust a band’s center frequency by turning its knob.
