QUICK START GUIDE WITH CABLING EXAMPLE

Make sure that the mixer and all devices to be connected to the mixer, are turned off.
Connect the devices to the mixer using appropriate cables.
Adjust the input gain of the mono channels 1 and 2 and all level controllers channel-LEVEL and MAIN MIX to minimum (left stop). Place all equalizer controllers in the central position (stop). Adjust the volume controller on the active loudspeaker to minimum. Turn on the +48 V phantom power on the mixer only if you are using a condenser microphone.
Turn on the devices in the following order: Microphone and keyboard (or other source devices), the mixer and lastly the active speakers.
Always adjust the gain control of the mono channels so that the peak LED of the corresponding channel only lights up briefly when signal peaks occur. Avoid the permanent lighting of the peak LED by reducing the input gain (Gain).
Channels 3/4 and 5/6: Adjust the output level of the keyboard (or other source devices) so that the peak LED above the corresponding channel only lights up briefly when signal peaks occur. Avoid the permanent lighting of the peak LED.
Bring the level controllers (LEVEL) of the channels in use and of the sum channel MAIN MIX approximately to the 3 o’clock position.
Now increase the volume of the active speakers for the incoming signal (e.g.speaking, singing, keyboard) to the desired level.
Fine-tuning can now be achieved by adjusting the volume ratios of the channels and by using the equalizer and effects device (model LDVIBZ6D only) as desired.

NOTE: When turning off the devices, please follow these steps: First, set the volume of the active speakers to minimum and turn them off, then the mixer and connected devices can be switched off.
