Madrigal Imaging N380S ユーザーズマニュアル

PRESS AND HOLD THE MODE BUTTON AGAIN…
until the display reads

NEW DATA

This indicates that your new

automatic output level

has been stored in

nonvolatile memory. Your Nº380S 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 Nº380S 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 Nº380S provides a user-defined

mute

function which quickly reduces the

output level by a predefined amount between 1 and 60 decibels. The factory de-
fault 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:

PRESS AND HOLD THE MUTE BUTTON
Wait until the display reads “

MUTE

” and a number (which will read “-20” as

delivered from the factory).
