Congratulations on the purchase of your new RANDALL DIAVLO SERIES Amplifier! We at Randall Amplification appreciate that you chose our brand of guitar instrument
amplifiers and wish you years of great tone and enjoyable playing time with your new machine. Please review the safety instructions and be aware that the documentation
provided in this manual references 120volt USA versions of the models covered. Note that the POWER listed on the power supply should be for your countries’ power standard.
Class A Discrete
instrument level effects
loop send. This plugs
into external pedal
effects unit input and
feeds signal from the
Gain and Tone knobs.
Also serves as
unbalanced preamp
output send but will mute
output unless return jack
receives return signal.
1/4” Guitar input - Plug
your guitar into this jack/
connector.
GAIN KNOB - This knob works as
an aggressive all tube overdrive
circuit. It dynamically responds with
more overdrive as more input is fed
from your pickups. Turn to the right
for more saturation. For cleaner
tones, keep at lowest setting, turn
volume all the way up and use gain
knob as volume output control.
T.S.S. - Stands for “Tone Stack Shift” 3-way Midrange frequency variance switch.
•Left- Midrange boost, with flat bass response and rolled off highs....great for smooth
burning lead tones
•Center- The stock position with an even bass, mid, and treble response....perfect for
Rock
•Right- Midrange scoop, with a boosted bass and treble response...perfect for metal
TONE KNOB - This is
an overall tonal sweep.
Turn to the left for more
bass (low frequencies)
and less treble (high
frequencies)
XLR ground lift
changes the ground
connection to fix
ground loops when
interfacing with other
equipment - use at
quietest setting for
best performance.
Speaker output - plug
any (8 ohm or greater)
speaker cabinet into
this jack. External input
will automatically mute
the internal speaker so
only external speaker
operates.
POWER CABLE:
Note that this unit will
only operate safely in
the country or region
in which it is sold.
please contact your
local Randall
distributor or dealer if
you are unsure of
mains voltage.
Class A Discrete
instrument level effects
loop return. This plugs
into external pedal effects
unit output to complete
signal “loop”. Also serves
as power amp input so
external preamp can be
plugged directly to power
amp section with active
volume control and
speaker emulator XLR
output.
VOLUME KNOB - Overall volume
output control. This feeds the
speaker output and balanced XLR
speaker emulator output.
Note that to achieve cleaner tones,
turn volume all the way up and use
GAIN KNOB as volume control.
XLR Balanced output is signal fed from the
output transformer including signal from the
output tube. This signal is then sent through
the speaker emulator which simulates the
sound and response of a mic’d up Randall
4x12 speaker cabinet. This function is useful
for direct (silent) recording, Direct send to
PA/FOH for silent stages, in ear monitor feed
or send to external power amp.
The Power
switch turns
the unit on
and off.
Speaker MUTE switch - This function
is only on combo versions RD1C &
RD5C. When depressed it mutes the
output of the internal speaker for silent
operation. All of the functions of the
amplifier operate as normal except the
speaker output. Note that the amplifier
has internal resistor to offer simulated
speaker impedance and protection.
