“NOISE GATE” function
NOISE GATE, or residual noise suppressor, is a function to reduce noise of the speaker
without input audio signal applied.
NOISE GATE starts to work when there is no audio signal on input, after a few seconds, it
sets the amplifier section in MUTE state . MUTE state is indicated by slow flashing, of
“MUTE/PROT” yellow led. As soon as the audio signal passes he input section, the
speaker is set out of MUTE status automatically.
This option can be enabled and disabled according to the follow procedure on the
amplifier’s module.
1) How to check NOISE GATE status
The NOISE GATE status is visualized by the leds located on the amplifier panel during
switching on the module.
Function enabled =all leds flashes steady for 5-6 second.
Function disabled = only “MUTE/PROT” yellow led flasches steady for 5-6 second
2) NOISE GATE enabled/disabled
NOISE GATE enabled/disabled can be done each time when switching ON and OFF the
amplifier module with “SET-UP MODE” selector on position “9 “(service use only).
To enable/disable NOISE GATE function follow this procedure:
-
Amplifier switched OFF
-
Set “SET-UP MODE” selector in position "9"
-
Switch ON the amplifier module and check following:
* if “LIMITER" red led steady flashes for a few seconds, the NOISE
GATE is enabled.
* if “LIMITER" red led flashes fast for a few seconds, the NOISE
GATE is disabled
Warning!
After enabling or disabling the NOISE GATE function, switch off the amplifier, select
“SET-UP MODE” selector in any equalization position (except of "9" position) and
switch the system ON.
