Gain Reduction / Compression Meter
When using SpectraComp™, the compression meter (16)
indicates 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 used for bass guitars on the market
is based on the “full band” principle. This means that the
compressor will respond to the full (20 Hz to 20 kHz) frequency
range and apply the same compression over the whole 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 BH500 head 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.
4/5/6/7 – TONE Controls
The BH500 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.
Tone Controls Center Frequencies:
Center Freq: 100 Hz (Gain: +15/-24 dB)
Center Freq: 335 Hz (Gain: +15/-24 dB)
Center Freq: 900 Hz (Gain: +15/-24 dB)
Center Freq: 1600 Hz @ Gain: -24 to 0 dB
4000 Hz @ Gain 0 to +15 dB
