2 ADJUST THE VOLUME KNOB TO YOUR PREFERRED SETTING
You may select any value between -1 and -60 decibels (inclusive),
in one-decibel increments.
3 PRESS AND HOLD THE MUTE BUTTON AGAIN
When the display reads NEW DATA, the Nº38 will have saved your
new setting in non-volatile 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 output control 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 unexpected, large increases in volume which might
cause inadvertent damage to your loudspeakers.
The Nº38 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, except 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 operation, simply press and hold the mono button again to
toggle back into the normal volume mode of operation. The display
will read LOCK OFF to indicate the return to normal operation.
