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.

MIDI BANK A/B
This button activates MIDI bank switching
mode. When you press this button, the LED
located above the button flashes to indicate
that "Bank Switching Mode" is active. Now
when you press one of the buttons (10)
through (15), the unit switches to the other
MIDI bank and the appropriate MIDI program
location number is sent via the MIDI OUT jack
(19). To avoid confusion, keep in mind that the
LED illuminates continually when you switch to
Bank B and is extinguished when you switch to
Routed To Headphones (a) Or HiFi Cab.
Guitar Cab. (b)
Selector switch for the HEADPHONES OUTPUT
jack (20). Set the switch to the left position (a)
when you connect stereo headphones or hi-fi
speakers and to the right position (b) when you
connect a guitar cabinet to ensure proper
frequency compensation for the respective
systems.

AC Fuse Box
Contains mains fuse (rear chamber) and spare
fuse (front chamber).
NOTE: Ensure replacement fuses bear identical
ratings (refer to the table page 10)!
19
MIDI OUTPUT
5-pin, standard MIDI diode port for connecting
the MIDI cable. Patch it to the MIDI IN jack of a
MIDI-capable device. The appropriate MIDI
program location number is sent via this
interface whenever you press one of the
buttons (10) through (15).
20
STEREO HEADPHONES OUTPUT
1/4" stereo output designed for stereo
headphones. You can also connect hi-fi
speakers or guitar cabinets. When you connect
a conventional guitar cabinet set the selector
switch (21 to ,,Routed to Guitar Cabinet."
CAUTION! Ensure You Heed The Following:
Always use a 1/4 STEREO plug. If you use a
mono plug, it may short-circuit and destroy
the poweramp!
FREQUENCY COMPENSATED LINE
OUTPUT: RIGHT
Line Out for the preamp's right frequency
compensated signal (1/4" unbalanced jack;
related to ground).
This signal can be patched directly to a mixing
console or a recording device. Ensure you use a
shielded cable for this signal circuit.
The LINE outputs (22) and (23) provide signals
that emulate the response of a 412 guitar
cabinet. The signal level is nominally identical to
the level at the LINE outputs (24) and (25).
However in practice, the level deviates slightly
due to frequency compensation. When the
preamp is active, the output level of the LINE
outputs depends on the following factors:
the input level (Gain), the Volume control
settings for the respective channels, and in
some measure, the voicing section control
settings. This is why we recommend that you
dial in the desired sound via the control
features, set a desired FX level (if you have
connected a processor) and then use the LINE
LEVEL pot (26) to dial in a suitable level.
22
Bank A. Bank A (LED off) active is the default
setting when you power the Tube Toner up.
Note:
A MIDI program location number is not
routed out/sent via the MIDI OUT jack when
you press the MIDI BANK A/B button (16).
MIDI bank change example:
Say you want to switch from Crunch/MIDI
Program #2 (Bank A active - LED off) to
Bypass/MIDI Program #10. Program #10 is in
Bank B, so you have to switch banks. You must
first press the "MIDI BANK A/B" button (16),
which activates MIDI Bank Switching Mode. The
LED located above the button (16) will flash.
Now press the "BYPASS MIDI 5/10" button (15),
which switches to MIDI Bank B. MIDI Program
Location 10 is routed out via the MIDI OUT jack
(19).The LED above the button (16) illuminates
continually, which tells you that MIDI Bank B is
active. Now if you select a another preamp
channel, the amp sends the appropriate MIDI
program location number (#6 through #10).
If you own a multi-effects device that features
an integrated preamp, you can use two of the
unit´s preamp settings separately via the
Bypass circuitry. If you are using a multi-amp
setup or have patched the Tube Toner signal
directly to a combo, you can send your guitar´s
signal directly to the preamp of the combo via
the bypass circuit without coloring the tone of
your original instrument signal.
