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.
For silent operation leave speaker
output unplugged. All of the functions
of the amplifier will operate as normal
except the speaker output. Note that
the amplifier has internal resistor to
offer simulated speaker impedance
and protection.
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.
