INPUT
- A low noise, high impedance
instrument input for all types of
instruments, active and passive.
___________________________________
CHARACTER
- The Classic 500 provides
a
preshaping
filter,
character
, which
operates independently from the filter
section. This gives the user the opportunity
to preshape the sound before the final
processing with the filters.
When pressed to its inner position, a boost
is achieved in both the bass and treble
ranges, while the midrange is being slightly
cut.

GAIN
- Control to adjust the instruments'
signal strength to the right operating level in
the Classic 500.
For optimum basic signal level, turn up the
GAIN knob until the PEAK led starts
flashing from the strongest signal from the
instrument.
Note: A correctly set GAIN is vital for the
signal processing to work properly in the
Classic 500.
DRIVE
- The DRIVE knob controls the
amount of gain in the tube emulation
stage, and provides an extra gain all the
way up to 30 dB. The gain is
compensated over this section producing
a warm overdrive while the output
remains more or less constant. This
control also compresses the sound when
turning up level up to maximum,
producing a pure tube like limitation.
The lower frequencies below 250 Hz are
bypassed in the Drive stage, producing a
warmer distortion without saturation,
allowing the player to add more low bass
than with conventional bass amps. The
bass is compensated over the tube stage,
which gives the same bass response up to
mid distorted levels.

VOLUME
- The VOLUME knob controls
all volume in the unit, controlling the
power amp and LINE output. The
balanced output (XLR) is not effected by
the setting of this knob.
__________________________________
STANDBY
– This switch mutes all
outputs and disconnects the speaker
outputs. This is suitable for tuning your
instrument or when you wish to change
speaker connections without powering off
the amp.

POWER
– Powers the unit on or off.
