until the display reads
NEW DATA .
This indicates that your new automatic output level has been stored in
nonvolatile memory. Your Nº380 will now automatically return to this vol-
ume setting whenever this input is selected. To reverse this situation, simply
readjust the
input offset as described above (in “programming input off-
sets”).
Note: It is necessary for the Nº380 to have an Input Offset of 0.0 in
order to access the AUTO setting. As a result, it will be
necessary to save a 0.0 Input Offset before selecting AUTO if a
higher offset was previously saved.
programming the
mute function
The Nº380 provides a user-defined mute function which quickly reduces the out-
put level by a predefined amount between 1 and 60 decibels. The factory default
setting is -20 dB.
If you regularly listen at relatively high sound pressure levels, you may wish to
increase the magnitude of the change brought about by engaging the
mute but-
ton. For example, a -20 dB change from an average of 95 dB SPL would bring the
volume in the room down to 75 dB SPL. If used in response to the telephone
ringing, you would probably find 75 dB SPL of music in the background too loud
for a comfortable telephone conversation.
To alter the change introduced by the Mute function:
1 PRESS AND HOLD THE MUTE BUTTON
Wait until the display reads “
MUTE ” and a number (which will read “-20” as
delivered from the factory).
