indicates that the amplifier has reached its
maximum output level.
Mains On/Off Switch
– This switch turns
the system power on or off. The switch
illuminates to indicate the presence of AC
power present in the chassis. This switch is
prior to the fuse.
The switch light can
be on even if the fuse is blown
The
light in the switch may flicker depending on
local voltage conditions. This is normal and
nothing to be concerned about
Speaker On/Off Switch
- This
switch
turns off the loudspeaker out put jacks .
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.
Models come with a holder
marked (FUSE) they are factory configured
for 100/120/ 230/240 only and must be
adapted by a service tech for any voltage
change. The standard fuse for U.S. use is
(5) Amp slow blow or time delay.
Do not use fast blow fuses.
Amp Outs
– These consist of two ¼ inch
jacks and a NL-4 connector. The jacks are
wired in parallel. The total speaker
load impedance should not exceed 4 ohms.
Amplifier Power Rating:
350 Watts RMS @ 8 Ohms
405 Watts RMS @ 4 Ohms
550 Watts RMS @ 2 Ohms
Mono Pre Tone 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 before the enhance control
and the tone section
.
Recording Out
– This fully balanced XLR
output allows you to send a pre or 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.
Stereo Aux. Input -
The standard ¼
mono jack is designed to accept the signal
from an external source such as a CD or
cassette player, drum machine, synth.
module, etc. The signal is summed prior to
the master volume control. The signal
enters the system before the tone controls.
These jacks can also be used to return a
studio cue signal, allowing the Time Traveler
to provide you with your own headphone mix
in the studio.
Amplifier Break Link-
These are provide
to break the signal chain at the input to
the amplifier. This can be used as an
insert point or control point for the final
amplifier
Tuner Out Jack
– This standard ¼ inch
jack is designed to provide a 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. The
signal is 2X input.
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 an AGC circuit if
the operating temperature goes above 190
degrees F. This circuit will automatically
turns down the output of the system in the
event of overheating. It will automatically
reset itself to full power 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 normally again.
(Note: the D.I. will continue to operate
