The multi band process is the core of the SOUND4 STREAM X. A unique set of options
controls each band, hence ensuring perfect sound stability.
Basic 3-Band Process
The basic mode applied the same setting to all 3 bands used in the process. The settings are
explained in details below.
Advanced 3-Band Process
When used in advanced mode, the 3-Band Process allows different settings for each band to be
applied. The bands are always organized as follows:
H - High frequency band
M - Mid frequency band
L - Low frequency band
Gate Threshold
– freezes the operation when the audio drops below the defined limit. When
the signal is too low, the Gate Threshold function will limit the floor noise. Down Expand – the
option works only when the corresponding band is frozen by Gate Threshold - It is intended to
retain the attenuation on the user-defined value. Then, according to the set attack and release
timed, the Down Expand automatically returns to the configured value. The combination Gate
Thr Down Expand is very useful when noisy sources such as microphones are evident.
Fidelity – controls the spectral balance between the bands. For example:
• If Fidelity is set to 0, the sound will be more rich as the bands will work independently;
• If Fidelity is set to 100, the sound will be purer as the bands are linked to the spectral
distribution at the input.
Sound Impact System
– maintains the authenticity of the original sound attacks. Pay special
attention when using the Sound Impact System with values higher than 6 as the average power
of the sound will significantly increased. In this case you may need to lower the Band Limiter or
Final Limiter drive.
