REAR PANEL FEATURES
Combination Power Cord Jack and
Fuse Holder
– The removable power cord
is attached here. Pulling the holder out of
the top of the power inlet accesses the fuse
carrier. Your unit was shipped with a spare
fuse inserted in the fuse carrier. USE ONLY
THE SAME SIZE AND TYPE FOR
REPLACMENT. U.S. users should make
sure the fuse holder is installed so the “115
VOLTS” reads right side up. For Europe the
230 should be right side up. Some European
models come with a holder marked (FUSE)
they are configured for 230 / 240 only and
must be adapted by a service tech for U.S.
standard voltage. The standard fuse for U.S.
use is (5) Amp slow blow or time delay.
Do not use fast blow fuses.
Amp Out – These two ¼ inch jacks accept
the speaker connection cables. The jacks
are wired in parallel. The total speaker
system impedance should not exceed 4
ohms.
Effects Send/Return – These standard ¼
jacks allow you to send and receive your
signal to and from external devices. The
effects loop is positioned post (behind) the
compressor and enhance control and prior
to the tone section.
Recording Out – This fully balanced XLR
output allows you to send a post-EQ/pre-
master signal to a recording or sound
reinforcement mixing console. This output
is designed to allow use with phantom
powered systems. Pin 2 + signal.
D.I. Level – Controls the level being sent
from the XLR balanced output jack.
Ground Lift Switch – This switch lifts the
ground within the balanced output system to
allow you to eliminate excessive noise when
connected to external systems.
AUX In Right / Left - These standard ¼
mono jacks are designed to accept the
stereo signal from an external source such
as a CD or cassette player, drum machine,
synth, module, etc. The stereo signal is
summed prior to the master volume control.
The signal enters the system post the tone
controls. These jacks can also be used to
return a studio cue signal, allowing the
WT-400 to provide you with your own
headphone mix in the studio.
Tuner Out Jack – This standard ¼ inch
jack is designed to provide a post-tube, pre-
gain signal for connection to a tuner. It can
also be used to provide pre-tone signal to
other devices such as a direct box or
console.
Cooling System – Your amplifier features
a thermostatically controlled fan, which will
switch on when the internal temperature
reaches 130 degrees F. In low volume
situations (into 8 Ohm loads) the fan may
not come on at all. The system also
features a high temperature thermal safety
system that will activate if the operating
temperature goes above 200 degrees F.
This circuit will turn the system off in the
event of overheating. It will automatically
reset itself as soon as the unit cools down to
a safe operating temperature. Usually it
takes from 2 to 5 minutes before the unit will
begin to operate again. (Note: the D.I. will
continue to operate normally even when the
amplifier is in thermal shut down only the
stage sound will be lost.)
OPERATING INSTRUCTIONS
MECHANICAL AND THERMAL
ISSUES
– Your amplifier should always be
placed for operation away from sources of
moisture or heat. Care should be taken not
to obstruct the ventilation holes on the top
and sides of the unit. In the event of thermal
shutdown, you should eliminate the cause
of the thermal problem (poor ventilation,
speaker loads lower than 4 ohms)
immediately. The supplied rack ears can be
used to install your amplifier in a
conventional equipment rack for protection
during transportation.
ELECTRICAL CONNECTION – The WT-
400 requires at least 12 Amps of correctly
wired alternating current for proper
operations.
CONNECTIONS
– All line connections
(everything but the speakers) should be
