LEVEL
When shipped, the 300 is set for the Analog I/O configuration. Once you have
connected the analog inputs and outputs, you can set up the analog input and
output levels. To do this, press the 300 front panel key marked LEVEL. The
display will show:
Setting Analog
Audio Levels
The front panel PAGE UP and PAGE DOWN keys allow you to switch the display
from input levels (IN L and R) to output levels (OUT L and R).
When a line is selected, the boxes on the display will be lengthened. (The
illustration above shows the upper line selected.) If both lines on the display are
selected, turning the Soft knob will alter both settings simultaneously. The
buttons directly above and below the display act as toggle switches to individu-
ally select and un-select these lines.
If additional gain is needed, the rear panel INPUT GAIN switch allows you to set
unity gain of the 300 to 0dB (switch OUT), or to +16dB (switch IN).
Feed a 1kHz tone (or a musical signal at the maximum peak level used in your
system) to the 300. Use the front panel Soft knob to adjust the level so that the
peak input level falls just short of lighting the red overload LED. To set the output
level, press the front panel PAGE UP or PAGE DOWN key and use the Soft knob
to set the output to provide appropriate levels for your console or system.
Press this button to toggle
selection of INL on and off.
Press this button to toggle
selection of INR on and off.
Actual level settings (in dB)
are shown here.
This line is selected, and will
change as you turn the Soft
knob to give a visual indica-
tion of the level settings
