Re: EDP input gain

[Bret <echoplex@yahoo.com>]

Luis, 
If you are getting distortion with an EDP, just turn
the input gain down.  That is all it takes.  If the
output is then too low, then turn the output up higher
to compensate.

All changing the internal resistors do is to change
the input gain structure.  It does not change the
overal signal to noise ratio of the edp, and does not
change the dynamic range of the edp.  The distortion
occurs when your analog signal is to large for the adc
to handle.

If you have distortion you have too much input signal,
period.  Reduce the level of that signal either at the
instrument, the mixer, or the edp input knob.  Any of
these actions will reduce the signal into the adc
section of the edp, and will get rid of the
distortion.

As noted, high frequency signals will distort at a
lower level than low/mid frequency signals.  If a high
frequency signal distorts, turn the input gain down. 
The answer is always the same. Distortion means you
should turn down the input to the edp.

If reducing the input to the edp does not remove the
distortion, then something else is wrong, and changing
the input gain resistors is not the fix.
