Clipping Indicators:
The 14B uses tricolor LEDs with green indicat-
ing power on, flashing red indicating actual
overload or distortion and yellow/orange indicat-
ing thermal shutdown. Upon power-up the
14B’s LED’s will remain “red” until all voltages
stabilize and the unit comes out of mute and the
LED turns green.
If the LED indicator contains a substantial red
content, when program is present, it should be
considered as a sign that the level is too high
and may cause speaker damage if it continues.
It should be remembered that the Bryston ST
series are powerful amplifiers, and that it is pos-
sible to damage almost any speaker if an ampli-
fier is used in a thoughtless or abusive manner.
Bryston will not be responsible for speaker dam-
age caused in this manner.
The clip-sensing circuit uses an AC comparator
to detect any source of signal distortion includ-
ing clipping, short circuits in cabling, excessive
DC or supersonic signals, whether at the input
or output. Most conditions which could cause
the red LED to light for more than a moment or
two can be dangerous to your loudspeakers
and should be corrected immediately.
If a specific LED remains ‘yellow/orange’ without signal present,
it may indicate a thermal shutdown condition and the channel
will remain inoperative until safe operating temperatures return.
