OPERATION

MANUAL

Please visit our website www.randallamplification.com

Congratulations on the purchase of your new RANDALL RD 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.

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)

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.

1/4” Guitar input -

Plug your guitar into this jack/connector.

The Power switch turns the unit on and off.

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.

Speaker output - plug any (8 ohm or greater) speaker cabinet into this jack.

(already connected on combo models)

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

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.

XLR ground lift changes the ground connection to fix ground loops when interfacing with other equipment - use at quietest setting for best performance.

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.

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.
