RH450 will automatically return to normal mode. In normal
mode, the GAIN knob controls the amplifier’s gain level.

Gain Reduction / Compression Meter
When using SpectraComp™, the light-ring around the GAIN
knob doubles as a compression meter, showing you how much
compression is applied to the signal.
Auto Make-up Gain
As compression by nature reduces the loudest parts and peaks
of the signal, you may feel that many conventional compressors
“eat” the level of your signal, resulting in a lower output volume.
SpectraComp™ automatically compensates for compression
gain reduction, giving you an even output volume.
Spectral Compression vs. Full Band Compression
Virtually any compressor on the market for bass is based on a
“full band” principle, meaning that the compressor will respond
and compress identically across the full (20 Hz to 20 kHz)
frequency range.
From the low E (or B) string to the G string: The electric bass
has a very wide dynamic range. When using standard
compressors, the low E string will – due to its higher energy –
control when and how the compressor responds to and shapes
the entire signal. The typical result is that either the G string is
not compressed at all or that – just when the G string starts to
sound right –, the low E string is compressed too strongly. In
other words: You are constantly dealing with a tight and difficult
compromise.
With Spectral Compression, the RH450 amplifier uses a different
approach that allows for independent compression of the Low,
Mid and High frequency areas. This way, the right amount of
compression is added to the individual strings of your bass,
resulting in a smoother and much more transparent
compression.
4 – TONE Controls
The RH450 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.
So if you feel that the RH450’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.
