Your new Acoustasonic SFX amplifier delivers astonishing sound with award-winning SFX (Stereo Field eXpansion, patent pending) technology. Equipped with 32 DSP (Digital Signal Processor) stereo effects, the Acoustasonic SFX “psycho-acoustic” phenomenon is receiving industry acclaim and has become the defining event in the next level of musical experience. As a member of the Fender family, your Acoustasonic SFX has professional features built-in:
•Independent channels for acoustic instruments and vocals with individual tone and feedback controls .
•80 watts per channel @ 8Ω (160 Watts R.M.S. Total).
•10and 8-inch “Special Design” speakers, and a piezo horn for clean, powerful response.
•Exclusive “String Dynamics” control for suppressing high-frequency acoustical instrument harshness.
•Noise reducing phase reverse switches.
•Balanced 1/4 inch TRS (Tip/Ring/Sleeve) and 3-Pin XLR input jacks.
•Insert jacks for connection to external equipment.
The sound waves from a traditional guitar amplifier project forward, focusing their energy in one direction.
Fender’s Stereo Field eXpansion circuitry processes the signal through one of 32 stereo digital effects. The stereo signal is then processed by the SFX matrix circuit and sent to the speakers creating a psychoacoustic event that results in up to 300º of stereo imaging.

1.INSTRUMENT - Plug your guitar in here.
2.GAIN - Adjusts the loudness of the instrument channel.
3.TREBLE - Adjusts the high frequency range of the instrument channel.
4.MID - Adjusts the middle frequency range of the instrument channel.
5.BASS - Adjusts the low frequency range of the instrument channel.
6.STRING DYNAMICS - Controls a dynamic tone shaping filter on the instrument channel. Rotating the knob clockwise reduces high-fre- quency “harshness” when playing at high volumes and maintains “crispness” when playing at lower levels.
7.FEEDBACK NOTCH - SLOWLY rotate this knob to locate and suppress feedback at a specific frequency on the instrument channel.
8.DSP SEND - Adjusts instrument channel send level to the DSPeffects circuit.
9.INSERTInput/output jack* (TRS) for instrument channel connection to effects devices and other line-level equipment.
10.MIC - Plug your microphone in here. This three pin XLR balanced female input connector is intended for input signals from low impedance microphones.
11.LINE/INST - This 1/4 inch TRS input jack is suited for line-level equipment such as high impedance microphones, keyboards and drum machines. It accepts both balanced and unbalanced inputs.
12.GAIN - Adjusts the loudness of the mic/line channel.
13.PHASE - Reverses the phase of the mic/line channel useful for eliminating feedback in instruments using dual pickup configurations.
14.TREBLE - Adjusts the high frequency range of the mic/line channel .
15.MID - Adjusts the middle frequency range of the mic/line channel.
16.BASS - Adjusts the low frequency range of the mic/line channel.
17.FEEDBACK NOTCH - SLOWLY rotate this knob to locate and suppress feedback at a specific frequency on the mic/line channel.
18.DSP SEND - Adjusts mic/line channel send level to the DSP effects circuit.
19.INSERT - Input/output jack* (TRS) for mic/line channel connection to effects devices and other line-level equipment.
20.BYPASS - Switch IN disables the SFX effect.
21.SFX - Adjusts the SFX effect level and intensity.
22.SFX ON - Illuminates when the SFX effect is active.
23.DSP RETURN - Adjusts DSP effect level (wet signal) to be mixed with the “dry” signal. Clockwise rotation increases the DSPwet signal level.
24.MASTER VOLUME - Adjusts overall loudness of the Acoustasonic SFX.
25.OUTPUT PHASE - Reverses the phase of the amplifier, useful for reducing “small environment” feedback.
26.POWER - Illuminates when the Acoustasonic SFX is ON and receiving power.
27.DSP EFFECTS - Select from 32 DSP effects. The DSP send knob must be turned above “1” for the effect to be heard on either channel. The DSP effects are listed on the next page.
28.CLIP - Flashes when clipping (distortion) is present in the DSP circuit. If unwanted distortion is heard on either channel when this LED flashes, reduce the DSP send level on that channel.
29.SIGNAL - Illuminates when an adequate input signal level exists for proper operation of the the DSP effects circuitry. Increase the DSP send level on each channel in turn so that the signal LED is illuminated when playing at a normal volume for that channel.
*“Insert” jacks on the Acoustasonic SFX utilize the “Y–cord” (stereo-TRS to dual mono-TS) configuration with Tip=send, Ring=return and Sleeve=ground.
The DSP effect descriptions below are listed in the order as they appear going clockwise around the DSP effects knob.
To choose an effect, rotate the dial to
point at one of 32 effects. The DSP send
and DSP return knobs must be turned above “1” for the any effect to be heard. Note that the intensity (speed, depth, room size) of each TYPE of DSP effect
increases going CLOCKWISE around the DSP effects knob, until reaching number 1 of the next TYPE grouping.

30.POWER SWITCH - Push in the upper-half to switch ON the unit. Push in the lowerhalf to switch OFF the unit.
31.LINE CORD - The power line cord must be connected to a grounded AC receptacle in accordance with the voltage and frequency ratings as listed on the rear panel under INPUT POWER.
