You may select any value between -1 and -60 decibels (inclusive), in one- decibel increments.

3PRESS AND HOLD THE MUTE BUTTON AGAIN

When the display reads NEW DATA, the Nº380 will have saved your new set- ting in nonvolatile memory.

The mute button will toggle you back and forth between the “normal” playback level and a level which is as many decibels below that level as you have elected to use as your mute function.

However, if you adjust the volume with either the volume knob or the remote control while in the mute mode, the preamplifier will adjust its volume from the muted volume and disengage the mute function. This design guards against unex- pected (and possibly unpleasant) large increases in volume when the mute but- ton is disengaged after raising the volume with the knob.

The Nº380 also allows a “maximum volume setting” to be established. Using this feature, it now becomes possible to “lock out” volume settings above a certain point in the preamplifier’s range.

In systems that have highly sensitive loudspeakers, the available +18.9 dB of gain may allow the system to be driven to dangerously loud levels. Alternatively, the presence of children in the home may lead the owner of the system to desire some restriction on how loudly it can be played.

In either case, setting the maximum volume is quite simple:

1.TURN THE VOLUME TO THE DESIRED “MAXIMUM VOLUME”

2.PRESS AND HOLD THE MONO BUTTON UNTIL THE DISPLAY READS LOCK SET

The display will time out after a few seconds and revert to its normal display, ex- cept that it will no longer allow you to exceed the chosen maximum volume. (Exception: the SSP mode will still override this feature and pass the surround processor’s front channels through at unity gain, regardless of the setting of the Volume Lock.)

If and when you want to restore the volume control to its normal, full range op- eration, simply press and hold the mono button again to toggle back into the nor-
