Powering Up

After making your connections, turn on the systemÕs power using this procedure:
Before turning on the Q20Õs power, check the following items:
¥ Have all connections been made correctly?
¥ Are the volume controls of the amplifier or mixer turned down?
Turn on the [POWER] switch on the front panel of the Q20.
Upon power-up, the Q20 will display the last selected Program, and the
[PROGRAM] buttonÕs LED will be lit. If this Program has been edited, the
display will indicate this by showing the word ÒEDITEDÓ, and by flashing the
Program Number and Name in the upper display.
Turn on the power of the amplifier/mixer, and adjust the volume.

Setting Levels

Proper setting of the [INPUT LEVEL] and [OUTPUT] knobs is crucial in order to
achieve the maximum signal-to-noise ratio (the concentric knobs allow the Left and
Right Input levels to be adjusted separately). As a good starting point, set both
input and output level controls at about 2 o'clock or 65% of full. This will decrease
the possibility of overload distortion and keep the amount of background noise to a
minimum.
For quietest operation, you should adjust the level of the source being sent to the
Q20 so that the green [-3dB] LEDs in the Q20Õs peak meter flash, but not so loud
that the red [CLIP] LEDs turn on. A nominal input sound make the -12dB LED turn on
Note: The Input and Output level controls effect the analog inputs and outputs only.
If you need to attenuate the digital inputs, you can do this in Page 2 of the Routing
pages. See Chapter 4 for more information.
