8. Operation
All these software parameters must be set directly on the hardware device. The sub
menu “User preset” where you can set parameters like gain, crossover frequency, limiter,
delays,…appears from preset no. 5 - 8.
The names of the menu points refer to the user navigation on the device.
Main Menu
•
Pot Lock Mode
[to be activated by using “lock function”, see page 13]
Pot locked
[just lock volume pot]
Pot unlocked
[just unlock volume pot]
In this menu item you can set a „lock - function“ for the volume pot of VL 750 / VL 760.
•
Sig LED Threshold
Here you can set the threshold value where the LED starts to light green when the set value is
reached by the audio signal.
•
User LED Threshold
Here you can set the threshold value where the LED starts to light blue when the set value is
reached by the audio signal. This function allows you to set an optical limit for the volume level
for your audience, e.g. -10 dB – you know your pre-set value is reached.
•
Power Mode
Last State
Audio Trigger
Always On
In this menu item you can pre-set the operating status of the VL 750 / VL 760:
If you choose „Last State“- mode, the VL 750 / VL 760 will always start in the last state of
operating after power cycle the unit (after power cycle the unit is muted!).
To reduce the power consumption e.g. in installations you can choose „Audio Trigger“- mode.
In this mode you can set a threshold value and a time value where the system automatically
switched off when the threshold is not exceeded with an audio signal. After the pre-set time the
unit is switched off. If the pre-set threshold value is exceeded during the unit is still on, the time
value counts again - that means this function is a posttrigger-function. You can switch on the
unit again by pressing the OK-button or playing an audio signal which has a higher input level
as the pre-set threshold value.
If you choose „Always On“, the VL 750 / VL 760 is always on. That means after apply power
supply the unit is automatically on and ready to play (the “lock function” can be active!).
