17 AC Fuse Box:
Contains mains fuse (rear chamber) and spare fuse (front chamber).
NOTE:
Ensure replacement fuses bear identical ratings (refer to the table)!
18 AC Socket:
Connect AC cord here.
CAUTION:
Ensure you use an intact AC cord with an insulated plug only!
Before you power the amp up, ensure the voltage value printed beside the AC socket
corresponds to the available current.
19 V.L.S. Ratio
:
Use this potentiometer to determine the balance between the two switchable
volume levels. We deliberately left the knob off this pot, but you can rotate the shaft to dial in the
desired preset. If you're operating the amp without a footswitch, "hi volume" (high-volume mode)
is active and this pot is disabled. You can switch between the Lo and Hi volume levels via a
standard two-way footswitch connected to Jack 20 (or via the MIDI Switcher). Turn the pot's shaft
clockwise to turn up the "lo volume" level.
20 Footswitch Gain Lo/Hi; V.L.S.:
1/4" stereo jack for double footswitches, executes the
following functions:
1. Gain mode switching between Lo and Hi (mono terminal).
2. Switching between the two volume levels (stereo terminal).
21 Footswitch Reverb:
1/4" mono jack for a single footswitch (e.g. Z-1)
that executes Reverb on/off.
6 Bass:
Bottom end voicing control, passive.
7 Middle:
Mid-range voicing control, passive.
8 Treble:
Upper range voicing control, passive.
A TIP from the Designer:To get an idea of this amp's capabilities, we suggest you set the tone control
pots Bass (6), Middle (7) and Treble (8) to the 12 o'clock position. For extremely soft blues or jazz
sounds, try setting the Treble knob to somewhere in the 8-to-11 o'clock range. For sparkling Clean
or spanky funk sounds, go for something in the range of 12 to 3 o'clock with the Treble control.
9 Reverb 1:
Reverb control, adjusts the portion of the reverb signal during the Lo Gain mode and
increases reverb intensity if you rotate it clockwise; the reverb can be switched on/off via the
respective footswitch connected to jack 21.
10 Reverb 2:
Reverb control, adjusts the portion of the reverb signal during the Hi Gain mode and
increases reverb intensity if you rotate it clockwise; the reverb can be switched on/off via the
respective footswitch connected to jack 21.
11 Lo/Hi:
Mode selector pushbutton for Lo and Hi Gain modes, red LED indicate Hi Gain
mode; This function can also be activated via the respective footswitch connected to jack 20.
Once a footpedal is connected, the mode selector pushbutton is deactivated.
12 Master 1:
Master volume control for power amp output during Lo Gain mode. The feature to
switch between two volume levels (V.L.S. - active or passive) can be accessed by means of the
respective footswitch connected to jack 20. Adjust the ratio between the two volume levels with the
"V.L.S. ratio" pot (see chapter 19).
13 Master 2:
Master volume control for power amp output during Hi Gain mode. The feature to
switch between two volume levels (V.L.S. - active or passive) can be accessed by means of the
respective footswitch connected to jack 20. Adjust the ratio between the two volume levels with the
"V.L.S. ratio" pot (see chapter 19).
14 Power-Indicator:
This LED indicates Power On, means the Amp is switched on.
15 Stand By:
Power amp standby switch: Use this switch to silence the amp when you take a lengthier
break. The amp's tubes stay warm, which means that it is ready to roll immediately when you switch
it back to full power. The standby switch is also well-suited for muting the amp for brief breaks, for
instance when you're switching guitars.
