ADJUST THE VOLUME KNOB TO YOUR PREFERRED SETTING
You may select any value between -1 and -60 decibels (inclusive), in one-
decibel increments.

PRESS AND HOLD THE MUTE BUTTON AGAIN
When the display reads 

, the Nº380S will have saved your new

setting in nonvolatile memory.

The 

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 

function.

However, if you adjust the volume with either the volume knob or the remote
control while in the 

mode, the preamplifier will adjust its volume from the

muted volume and disengage the 

function. This design guards against unex-

pected (and possibly unpleasant) large increases in volume when the 

but-

ton is disengaged after raising the volume with the knob.

The Nº380S also allows a “maximum volume setting” to be established. Using
this feature, it now becomes possible to “lock out” volume settings above a cer-
tain 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:

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 

 button again to toggle back into the nor-
