High Frequency Notch Filter (10)
This Filter is identical to the Low Frequency Notch Filter except that you can select a higher
centre frequency via the rotary control: between 800Hz and 20kHz.
High Frequency Notch Filter on/off Switch (11)
With this switch you can turn the high frequency notch filter on and off. Standard position is off
(LED out). Push the button if you want to switch the notch filter in the signal path, the LED will
light.
Equaliser Bypass Switch (12)
The bypass switch will connect the input straight to the output, thus bypassing all equalising.
In case of Power Failure the bypass is automatically activated
LED-VU meter and Clip LED (13)
There is an eight-section VU meter and one signal LED with a scale in 3dB steps which measu
-
res the signal on the output after all the filter sections. A separate Clip LED will light when you
have reached the maximum level of the
dBQzero
and no more headroom is left, this Clip
circuit monitors the signal at three different points in the signal path: input, post level control
and post filters.
If the clip LED lights verify your EQ setting but do not forget to bypass all the filters and make
sure your input signal is correct. Check this before the start of any show too make sure you are
feeding the unit with a correct level signal.
Power on/present indication LED (14)
When the power switch on the backside of the unit is on, and mains power is present, this LED
will light to assure you. In case of a power failure or if you have turned off the mains power
switch on the back of the unit, the unit will be/go in hard-bypass mode, hereby linking the inputs
to the outputs so that the signal goes true the unit unaltered.
