INPUT - There is a single instrument input provided linked to a PASSIVE/
ACTIVE selector switch. The Passive input (switch out) is high sensitivity
and also high impedance to suit the output from PASSIVE basses. The
Active input (switch in) is low sensitivity and lower impedance to suit the
output from ACTIVE basses.
INPUT CONTROL - The INPUT control sets the signal level through the
preamp in conjunction with the INPUT LEVEL VU Meter. This is adjusted
to give a reading of 0VU on the meter for average playing dynamics with
occasional peaks into the red region. Please note that the setting of this
may have to be re-adjusted after modification of the EQ controls.
PUSH FLAT / SHAPE - With this button in its OUT position a fixed E.Q. Is
superimposed on the preamp to give a bright but punchy character to
the sound. Pushing this button IN returns the preamp to a Flat frequency
response.
This function may also be controlled from a footswitch. For the footswitch
to operate this button must be in its OUT position.
VALVE DRIVE PLUS - This routes the signal either through a clean
Solid State amplification section (control on zero) or through a Dual
Triode Tube amplification/overdrive section in order to add either tonal
character i.e. warmth with the control set at 9 o'clock, a slight edge in the
sound at 12 0'clock through to an increasing degree of Tube distortion/
overdrive as the control is advanced to maximum.

USER GUIDE
A Mix of these two amplification sections can be achieved with this
control.
N.B. The degree of tube distortion provided by this control will also depend on the setting of the

INPUT control.

VALVE DRIVE IN/OUT - This push button switches the valve drive section
IN or OUT. This function may also be controlled from the Ashdown 4 way
footswitch. For the footswitch to operate this button must be in its OUT
position.
E.Q. IN / OUT - This push button switches the Equalisation section IN or
OUT i.e. the Bass, Middle and Treble controls plus the two sets of sliders
placed between each of these.
This function may also be controlled from the Ashdown 4 way footswitch.
For the footswitch to operate this button must be in its OUT position.
9 BAND EQUALISATION - This consists of BASS, MIDDLE and TREBLE
controls with three sliders placed between each control. This can be used
in a number of ways:
Firstly as a very simple Bass, Middle and Treble tone control section as
found on older traditional amplifiers. This is done by leaving the two sets
of sliders interposed between these controls set in their centre positions
and using only the BASS, MIDDLE and TREBLE controls to alter the overall
tone.
