INTRODUCTION Duality is a two channels, modern style, guitar amplifier. Thought as ultimate tone weapon, featuring rich but simple clean crispy sound and a tridimensional multi stage overdriven channel. Full MIDI implementation (CC and PC), double master volume and a high voltage buffered effects loop make Duality your life as guitarist easier than ever before.

NOTE: IMPORTANT…NOT TO DO! • Do not try to change output jacks (impedance) while the amplifier is on. You must turn STANDBY and POWER switches to OFF position before changing the output impedance. • Do not try to change input/output levels of you devices plugged into fx loop while the amplifier is on.
PREMISE PREMISE By developing this amplifier we had few main visions in our minds: 1 – THE AMPLIFIER MUST SOUND GOOD IN A MUSICAL CONTEST AND NOT IN YOUR BEEDROOM EXCLUSIVELY. This can be hard to understand to some people, but in every step of our developing process we recorded it through a professional studio recording system, making sure that all useless frequencies which can fight with bass guitar, synths or maybe cymbals in a live/recording environment are gone. A huge quantity of useless gain and can be...
This led us to take almost a year to develop this compact 50w all tube amplifier, the very first multi channel amplifier made by RedSeven Amplification. We are proud to say that this is not a clone of anything. You will not find any ingredients from any other builder inside.
TECHNICAL FEATURES FRONT PANEL: (from left to right) • STANDBY / ON SWITCH: turn the amplifier in standby mode or in operative mode. • RED LED: (under STANDBT / ON SWITCH): this led will indicate the state of incoming power supply. It will turn on if everything is ok. •...

REAR PANEL (from left to right) • SEND & RETURN: Connection between pre amp and power amp. Duality is shipped with pedals friendly level. • PRESENCE: global setting for presence control. It acts on both channels. • OUTPUT IMPEDANCE: parallel jacks for connect your cab or cabs. •...
FIRST USAGE Before plug the power cord make sure to check the input voltage of the amplifier and be sure to match it with your wall voltage, and then insert the power chord. Before plug the speaker cable, check the impedance of your cab and match the output impedance of amplifier with impedance switch on rear panel, than connect the speaker cable from cabinet to amplifier.
MIDI Duality, despite the full tube audio signal path, is equipped with digital memory which can make saving combinations (preset) of functions inside the amp. Duality is shipped with presetted midi channel #1. You can’t change midi channel on the fly after bought it, but you can ask for a different midi channel at order time. All the functions are recallable on the fly via midi CC.
LOOP FX Loop effects on D50 is between preamp output and power amp input, right before master volume. It’s a buffered 100% serial loop fx with instrument level signal. When loop effect is engaged 100% of your sound will pass thru the effect wired to send/return jacks.
TUBE LAYOUT This amplifier comes with EL34B type tubes in the power amp section and 12AX7 in preamp, selected trusty partners Tube Doctor. Power tube can’t be changed with other type of tubes (i.e 6L6s, KT88s, etc), they can be substitute only with other EL34 type tubes.
CABINET AND SPEAKERS For the best sonic experience ever we highly suggest to play this amplifier with RedSeven Pro Cab series, especially with 4x12 model. We develop this amplifier thru this cabinet so this is the natural extension for it. We suggest you to try D100 with Celestion V30 or Greenback or a mix of both first.
By removing the amplifier form his wood cabinet or by making any modification to the original state will violate standard warranty and RedSeven Amplification will not responsible for any damage to people, things or animals. Revision 1.0 March 2018...
