The evolution of our acoustic amplification range has just moved on another stage! The Acoustasonic SFX® II amplifier has been updated and revised, bringing you the ultimate acoustic experience. Now, you can use this ingenious amp for anything from vocals to stringed acoustic instruments in a variety of different venues, regardless of the shape and size. From small, smoky bars to church halls, this amp will work its magic in any space due to its patented Stereo Field Expansion technology.

The Acoustasonic SFX® II contains one eight-inch Fender® Special Design, 8 ohm, 50 watt speaker, one six-inch Fender® Special Design speaker, set to a 90 degree angle, and one piezo horn.

At 2 x 80 watts this amp will cope with the largest of venues. There two channels: instrument and microphone and will suit all your needs for that unplugged gig you've been planning!

Among the staggering array of player features are a patented SFX (Stereo Field Expansion) system with side radiating speaker, a dual channel power amplifier, notch filter for feedback control, string dynamics control (which eliminates the harshness connected with string buzz, pick attack and other frequencies).

Also featured are on-board digital signal processing, insert patch points (for external signal processors) and ¼-inch instrument and microphone inputs.

The extensive controls on the Acoustasonic SFX® II includes the following:

• Instrument Channel - Gain, Treble, Mid, Bass, String Dynamics, Feedback Notch, Phase Reversal Switch, Insert Jack, Effects Select, Effects Level.
• Microphone Channel - Gain, Treble, Mid, Bass, Feedback Notch, Phase Reversal Switch, Insert Jack, Effects Select, Effects Level.
• Master Section - DSP Peak Indicator LED, AUX Level, AUX In RCA Jacks, SFX Level, SFX Disable Switch, Master Volume, Power On LED
• Back Panel - Footswitch Jack, Ground Lift Switch, XLR Balanced Line Out, Line Out Level, Right Insert/Line Out Jack, Left Insert/Line Out Jack, Instrument Tuner Out Jack.

The Acoustasonic SFX® II comes with a 3-Button Footswitch for Tuner Mute, and FX On/Off for Each Channel. What is SFX?

This is the technical bit, so pay attention! Stereo Field Expansion technology allows you and anyone within a 300° radius of your Fender® SFX amp to hear perfectly balanced, full-dimensioned, glorious stereo. But how does it work? With a mono source, like your guitar, the signal is first routed to the SFX amplifier's onboard digital signal processor. This DSP circuit was developed in Fender®'s own digital laboratory and features a whole host of stunning digital presets. Next, the stereo signals from the output of the DSP are routed to the SFX matrix, where they are encoded and prepared for the SFX speaker array.

The SFX speaker array is specially designed to be situated one on top of (and perpendicular to) the other in a cabinet design that will acoustically decode the encoded SFX sonic signatures. The result is an incredible stereo psycho-acoustic event which produces polarized sound waves for the Left and Right sections that will not mix - they repel each other so that when they finally arrive at your ear, they are completely separate.

An added benefit of SFX processing is that these sound waves are almost totally omni-directional, in excess of 300 degrees. So they fill the room from top to bottom, not front to back like conventional amps. The front row will hear about the same SPL (sound pressure level) as the back row.

This means that performances in rooms with terrible acoustics, uneven shape or high and low ceilings sound the same as performances in very nice-sounding rooms. In smaller clubs and bars, SFX technology allows you to fill the venue with even stereo sound. This means listeners seated at an acute angle to your rig will hear as well as those seated directly in front. In larger performance settings, your SFX amp serves as a highly effective onstage monitor system, allowing the other members of your band to hear you while performing at a lower stage volume than a standard amplifier will allow.
