SYNERGY SYN-20IR

All-Tube Head – 20 Watts – 3-Channel Preamp Module Platform Amp – IR Equipped

The SYN-20IR utilizes Synergy’s patented all-tube modular system, allowing you to quickly and easily swap preamp modules to endlessly expand your tonal palette. The SYN-20IR is the world’s most flexible, convenient, and tonally versatile all-tube amplifier head. The amp’s built- in vintage American-style clean channel coupled two additional channels from your favorite Synergy preamp module, makes the SYN-20IR a three-channel tonal beast ideal for every player, every style, and every situation.

Each all-tube, two-channel module is equipped with dual 12AX7s and features the exact preamp circuitry as the legendary amplifier it is based on. In most cases the SYNERGY module offers more features in comparison to the amp itself. The Synergy engineering team painstakingly works with each brand partner to design modules that achieve the most accurate
tonal representation of their famous amplifier model.

Brought to life by a 20-watt EL84 power section, the SYN-20IR is ideal for at home, in the studio, onstage, or at rehearsal. The SYN-20IR is packed with features to satisfy today’s demanding players including onboard impulse response (IR) technology with latency less than 1ms, selectable Power Amp Structure, silent playing, XLR DI and Headphone outputs and fully MIDI capability.

MODULES BASED ON LEGENDARY AMP MODELS
Synergy offers an ever-growing list of all-tube modules based on legendary amp models which include everything from IIC+ crunch and AC-style chime to BMAN bloom and even Steve Vai’s signature leads. This allows the SYN-20IR to offer unparalleled versatility and tonal exploration.

NEXT-LEVEL POWER AMP CONTROL
The SYN-20IR offers unique controls for STRUCTURE and REACTANCE that tailor the response of the amp’s all-analog power section. The revolutionary STRUCTURE feature optimizes the head for any channel by offering three distinct power amp configurations and feedback which are assignable to each of the amp’s channels. The STRUTURE feature significantly alters the overall contour and feel of the SYN-20IR.

There are three Structure modes to choose from:
• Mode A: Balanced negative feedback for a clear yet punchy sound
• Mode B: Vintage style phase inverter with relaxed mids and a bright, shimmering high end.
• Mode C: Modern HiFi style phase inverter and low negative feedback resistor delivers a modern, tight feel with solid lows and a darker high end.

REACTANCE is similar to a presence knob, but with a dynamic response and variable phase inverter which simultaneously shapes the middle and treble frequencies. This powerful control helps tailor the sound to your chosen module and Structure setting.

ASSIGN (POWER AMP) STRUCTURE and IR TO EACH CHANNEL
Right from the amp’s front panel, you can assign one of four impulse responses (IRs) and one of three POWER STUCTURES to each of the three channels. Easily manage and save it all to the included 3-button MIDI footswitch.

INDUSTRY-LEADING IR TECHNOLOGY
The SYN-20IR boasts a powerful digital engine dedicated to its four onboard impulse responses (IR) and power amp simulation in the most accurate and natural-sounding way. Utilizing an oversized 500 MHz ARM DSP processor, it delivers these professionally captured IRs with under 1ms of latency, far surpassing competing products. Add and manage your own IR library, as well as the 13 included IRs, using the free Synergy Editor software.

SEAMLESS CAB-LESS OPERATION
The SYN-20IR allows you to safely go front of house or to your recording device with unmatched response and realism without an external speaker cabinet. Superior to passive and reactive loads, whether running direct onstage, in the studio, or even utilizing the amp’s headphone output, you always get the perfect feel and sound with zero compromises.

3-BUTTON MIDI FOOTSWOTCH – MIDI CONTROL
The SYN-20IR includes an easy-to-use 3-button MIDI footswitch that lets you save and access any combination of channels, amp structures and onboard IRs. With the tap of your toe, you can, for example, switch from your module’s high-gain crunch with a 4×12 IR and StructureMode C to the amp’s onboard clean channel through a vintage 1×12 IR and the open-sounding Structure Mode A.

You can also connect external MIDI switchers and controllers, giving you access to up to 128 user-created presets. The included Synergy Editor Software makes it easy to assign and organize your presets for maximum flexibility.

SYNERGY EDITOR SOFTWARE
The included Synergy Editor Software unlocks the SYN-20IR’s full potential. Connecting via a standard USB jack, you can easily assign different IRs and Structure settings for your amp and module channels, load and organize your IR library, save up to 128 MIDI presets, and tailor your power-amp simulation via the assignable Low-Pass and Low Pass filtering. It’s all available within the software’s streamlined and easy-to-use interface.

UNIVERSAL VOLTAGE
The SYN-20IR works seamlessly anywhere in the world with the help of a voltage selector switch found on the back panel. When traveling or moving to a different country and want to take the SYN-20IR with you, there is no need to re-bias the amp or use a step-up/step-down transformer – just select the right voltage, replace the Mains fuse with the correct rating and you’re ready to go!

THE PERFECT AMP FOR EVERY SITUATION
Finding the perfect balance at 20 watts, the EL84-powered SYN-20IR is the working guitarist’s most valuable weapon. It’s designed for effortless portability while retaining rugged durability. The head’s compact size and light weight makes it easy to move between gigs, studios, or different rooms in your home. And the amp’s road worthy steel construction protects it to
ensure consistent performance every time you plug in.
