TC Electronic RH450, User Manual

1 – INPUT

You can connect an active or passive bass to this ¼" input jack.
The RH450 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.

2 – SPECTRACOMP™ (in Shift Mode)

Press the SHIFT button. Then turn the knob to adjust the

amount of SpectraComp compression.

SpectraComp™ uses a so-called spectral or multi-band
approach to compression, allowing for individual compression of
the low, mid and high frequency bands. Multiband compression
allows a significantly smoother and more transparent
compression without killing dynamics or tone.

SpectraComp™ is an advanced compressor, optimized to get
the best from a bass signal. If you simply want to hear it, press
the SHIFT button and turn the knob while playing. If you want to
know a bit more about what is going on behind the scenes,
