User manual FENDER 400 PEDAL STEEL GUITAR

[. . . ] The 400 PEDAL STEEL GUITARTM can be plugged into any instrument-level audio input with excellent results. 2 ONBOARD ACOUSTIC GUITAR SYSTEM PREAMP FUNCTIONS BATTERY COMPARTMENT Pull the small tab at the top of the 400 PEDAL STEEL GUITARTM toward you. The body of the preamp will swing out, revealing the BATTERY COMPARTMENT. Insert a fresh 9V alkaline battery. ENDPIN JACK The 400 PEDAL STEEL GUITARTM has no ON/OFF switch. It is turned on only when an instrument cable is plugged into the endpin jack. [. . . ] NOTE: Plug an instrument cable into the endpin jack before you plug into the sound equipment. BATTERY LOW INDICATOR When plugging into the endpin jack, the LOW BATTERY light will flash momentarily, indicating that the power is on. When the LOW BATTERY light stays on, it is time to change the battery. CONTROLS NOTCH FILTER This is a fixed level, variable-frequency filter for eliminating feedback or unwanted resonance. The NOTCH FILTER is effectively off in the full counter-clockwise position. 3 FISHMAN PREFIXTM PLUS VOLUME CONTROL Controls the overall gain of the 400 PEDAL STEEL GUITARTM. The center detent yields a flat response. CONTOUR This is a Wide-range semi-parametric filter. The CONTOUR Level slider controls the amount of boost or cut applied to the selected Contour FREQUENCY. The Contour FREQUENCY slider determines the frequency band that is boosted or cut by the CONTOUR LEVEL control. The frequency is variable from 250 to 10 kHz. TREBLE CONTROL This is a boost/cut shelving tone control. When boosted, the BRILLIANCE control can add presence to your sound or brighten up dead strings. PHASE SWITCH The PHASE switch compensates for acoustic phase differences that often occur between instrument and speaker. This "cavity resonance" feedback can be dealt with by putting the instrument and speaker out of phase or by adding equalization. Inverting the PHASE switch will put the instrument and speaker out of phase with each other, cancelling the low frequency feedback. If you move from your position on stage more than a few feet, you may have to invert the PHASE switch again to maintain an out of phase relationship between the mic'ed instrument and speaker. Continued . . . 9 FISHMAN PREFIXTM PLUS PHASE, Continued from Page 9 Here's why: A typical guitar has a cavity resonance of about 100 Hz. This is the frequency that generally feeds back when the guitar and speaker are in phase. If you set your PHASE switch to eliminate cavity resonance (out of phase) and then move 5 1/2 feet towards or away from the speaker, you will effectively put the mic'ed guitar/speaker relationship at 100 Hz back in phase; in the line of fire for low frequency feedback. The PHASE switch on the ONBOARD BLENDERTM in effect electronically "moves" your instrument's position relative to the speaker by inverting the phase 180° every time you flip it. B. USING THE NOTCH FILTER TO REDUCE FEEDBACK Notching out instrument cavity resonance will eliminate the low frequency feedback problem completely. The advantages to using notching equalization are: · The physical distance from the speaker will no longer be a factor for potential low frequency feedback. · The mic'ed instrument/speaker can remain in phase, maintaining a more natural and balanced response. 10 ONBOARD ACOUSTIC GUITAR SYSTEM SPECIFICATIONS Nominal Input Level: Input Overload: Input Impedance: Output Impedance: Nominal Output Level: THD: Signal to Noise Ratio: -20 dBV (20 Hz - 20 kHz)-2 dBV 20 M Ohms Less than 3. 5 k Ohms -12 dBV Less than . 04 %, -20 dBV input 77 dB (A weighted referred to nominal -20 dBV input) Less than 3. 5 mA 9V Alkaline battery (estimated 160 hours continuous use with low battery indicator at 6. 5V) 40Hz - 500 Hz (-15 dB) ± 12 dB at 60 Hz ± 3 dB at 350 Hz ± 12 dB at 10 kHz ± 3 dB at 2. 4 kHz ± 12dB (adjustable from 250 Hz to 10 kHz) Q = 0. 5 ± 9 dB at 10 kHz ± 3 dB Bandwidth 7 kHz Current Drain: Power Supply: Notch Filter Range: Bass Control Range: Treble Control Range: Contour Control Range: Brilliance Control Range: All specifications subject to change without notice. 11 LIMITED WARRANTY INSTALLATION BY A QUALIFIED PROFESSIONAL REPAIRMAN IS STRONGLY RECOMMENDED.
