How Use This Control - Solidyne HL 202 Manual De Usuario

ENGLISH

The optimal level of work is obtained when the indicator VU meter reaches the red zone.
Lower audio levels can affect the behavior of the VQR processing.

How use this control

Increase the threshold raising the NOISE fader until eliminating the background noise. An insufficient
level will do that the noise remains, although reduced. An excessive level will cause that the audio
appears "intermittent".
Next some important tips to take in mind when use this control:

If the background noise in the communication is very high, will be always over the
maximum threshold (fader at top) with which the expander/gate will not work
correctly.

Consider that the expander/gate releases whenever the audio signal is below the
threshold. If the background noise is very variable in level (noise from a street, for
example), it agrees not to use the NOISE CONTROL to avoid that during the pauses it
activates and deactivates generating an intermittent background sound. In these
cases it is preferred to leave the ambient noise.

Also can happen that the background noise is very notorious (a strong humming or
buzz) and although the gate can attenuate it during the pauses, the effect
"appearance" and "disappearance" of the noise is more annoying than the own noise,
due to a psychoacoustic phenomenon according to which the ear "is accustomed" to
the floor of constant noise when concentrating the attention in the word.
According to these advice, the good criterion of the operator will determine when it will make use of
the noise gate and in which cases it will prefer not to use it.
