4
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.
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
CXC-300/400 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 continuously operating low noise fan. 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 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.
ELECTRICAL CONNECTION – The
CXC amplifiers require at least 10 Amps of
correctly wired alternating current for proper
operations.
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.
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
