13.Noise Gate Option
The Entero power amplifier is equipped with a noise gate option to avoid reinforcing noise fed to the
amplifier input by the input signal chain. The noise gate can be switched on or off. All noise gate options
are selectable through the DIP switch at the rear panel of the amplifier.
The threshold for the noise gate is nominally set for an input signal of -54dBu and can be switched to an
input signal of -48dBu.
Noise Gate Parameters:
NG Nominal Threshold:
-54dBu RMS input signal
NG Optional Threshold:
-48dBu RMS input signal
NG Tail Time:
4 seconds
NG Attack Time:
max. 500us, typically 200us
NG Active Attenuate:
-90dB
The noise gate settings can be changed under regular amplifier operation without switching the unit off.
DIP SW 3:
On=NG Enabled
OFF=NG Disabled
DIP SW 4:
On=NG Thr6dB
OFF=NG Threshold Nominal
