Control on maximum "10" provides gain of 32dB ( x 5
approx. ) which is far more than should normally be
required.
NOISE NOTES: Background noise, usually residual hiss
and hum, may or may not be audible. Noise levels
usually increase as gain levels are boosted but may or
may not be more noticeable. But a higher output from
EDB-2 H.E may mean running subsequent devices in the
chain with less gain and producing less noise at those
stages. Every electronic device produces some noise in
operation. You may wish to provide the highest gain
levels from the devices in the chain with the lowest noise
levels?
EDB-2 H.E is a multi-function device which may be run
on batteries, which has made the achievement of a low
noise performance challenging, but this has been
attained. This is not mains powered, nor is it a limited
single function device, or a digital software, so some
small amount of noise is necessary. See Electrical
Specifications 19.2.7
6.2 GAIN & MASTER - JOINT OPERATION
Method A. After plugging in at a Gain of "0" with Mute
ON, turn Master up to about 2/3 CW or 2pm., then switch
Mute OFF and gradually turn CH.1 ( or CH.2 ) Gain
Control CW note: loose "slightly"until you have reached
the desired level at maybe 1/4-1/3 CW.
Method B. After plugging in at a Gain of "0" and with
Mute ON, switch Mute OFF and turn MASTER up a little
