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 which will activate if the operating
temperature goes above 190 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 1 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.) The system is set
up so that each amplifier is separately
protected.
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 requires 15 Amps of
correctly wired alternating current for proper
operations. The WT-600 and 500 require 12
Amps. The 800 should have 15 Amps
available.
CONNECTIONS
– All line connections
(everything but the speakers) should be
made with high-quality shielded cables. The
use of speaker cables for line connections
will result in excess noise. Speaker
connections should be made with high-
quality 16 gauge or larger unshielded
speaker cables. We recommend 10 or 12
gauge cables. The use of shielded line or
instrument cables for speaker connections
can damage your amplifier. The speaker
cable should be as short as possible.
TURN ON – We recommend turning your
system on with the master volume control
set to its minimum position. This will prevent
any unexpected signal from being sent to
your speakers. A crackling sound heard
through the system when it is first turned on
is the result of the tube warming up. This is
normal.
SETTING YOUR LEVEL – Effective use
of the gain control will ensure the best
signal-to-noise ratio. The Set Level,
Compressor, and EQ Clip indicators are all
provided to assist you in setting your level
correctly. You should begin the process
with your master control set to a low, or off
position, and your tone controls set flat.
While playing your instrument normally,
bring the gain control up until the set level
light or the compressor light winks on the
peaks that result from your strongest normal
attack. This will generally show up most on
your lower strings. You will use the
compressor light if the compressor is
engaged (enhance knob pushed in) and the
Set Level light if the compressor is disabled
(enhance knob pulled out). If more
compression is desired, increase the gain
control so the compressor light comes on
more readily. Having set your initial level,
you are now ready to proceed with setting
up your tone controls. Since tone
adjustments have an impact on the overall
preamp gain level, you may well need to
return to the gain control and repeat this
process once you have completed your EQ
adjustments.
SETTING UP YOUR EQ
Begin with all tone controls set flat and with
the Enhance Control set to its minimum
position. After setting your Gain level, bring
the Master control up to a moderate level.
Slowly bring the Enhance control up, playing
