Madrigal Imaging N380S owner manual 1PRESS AND HOLD THE MUTE BUTTON

Note:

programming the mute function

5PRESS 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”).

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.

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:

1PRESS AND HOLD THE MUTE BUTTON

Wait until the display reads “MUTE” and a number (which will read “-20” as delivered from the factory).
