2. MUTE
Use this function when changing
speaker cables or interconnects
without turning the amplifier off.
3. STANDBY
Use to keep circuitry in amplifier
ready for listening without initial
warm-up. If left in stand-by for
longer periods, use the mute
function, too.
4. LOW BIAS Can only be used
when the Automatic Green bias
is disabled. This position pro-
vides 50 Watts of pure class A,
more than enough for normal lis-
tening conditions and speakers
with normal sensitivity. In this
setting 150 watts of Class A/B
power is available.
5. HIGH BIAS - 100% Class A
power for the ultimate perform-
ance.
6. CHECK This function allows
you to check that all indicators
are operational.
The selectors (4-5) determines-
the degree of Class A operation.
In the 100% mode the Antileon
provides 150 watts of PURE
CLASS A power into an 8 ohm
load. The bias adjustments do
not change total output power,
but only the Class A operation
range.
With very efficient speakers,
175Watts of pure Class A might
rightly be considered overkill.
With LOW BIAS, efficient speak-
ers will be driven in Class A
most of the time.
Naturally, lowering the Class A
operation range reduces AC
power consumption at idle.
When evaluating the sonic effect
of the 3 bias adjustment modes,
it must be taken into considera-
tion that the Antileon requires
time to settle when bias is
changed. (5 min.)
Bias may be adjusted with the
Antileon turned on. However, we
recommende that bias adjust-
ment be made once and for all
during initial installation.
If the Antileon has been turned
off using the front panel on/off
switch, it will remember the last
bias setting. After using the mas-
ter on/off switch at the rear
panel, it will return to its last set-
ting.
Green Bias
If you own a Gryphon preampli-
fier with the green bias link, The
Antileon will automatically
change bias with reference to
the current position of the
Preamplifier´s volume control,
independent of the music signal.
If you wish the Antileon to go to
Stand-by for idling, you must use
the stand-by switch on the front
panel. Remember, the Green
