The tremolo is remotely controllable by use of the remote footswitch. 13. The six equalizer controls are used to blend the response characteristics desired in almost any conceivable combination. The six channel equalizer actually divides the tonal spectrum into six segments with each control allowing precise control over its particular band of frequencies. To set up the amp for the best sound, the six equalizer controls should be at the vertical (flat) position. When all the equalizer controls are flat, the course balance should be arrived at through use of the conventional bass, middle, and treble controls. Once the initial coarse balance is obtained the equalizer should be used to ''fine tune" the tone until a satisfactory blend is obtained. Operation of the standard tone controls in conjunction with the equalizer will yield almost any tonality imaginable. As with any sophisticated system, a thorogh understanding of the controls and a fair amount of experience is necessary to achieve the desired results. With the overdrive and/or the fuzz in operation it has been found that overboosting the high frequencies tend to emphasize the odd order harmonics and give a more harsh sound. Much smoother effects can be produced by using less top end and more middles and lows. It is important to remember that the equalizer is a true electronic crossover with each control acting as a volume control for its range. The over all loudness is a function of the setting of these controls. The amp should never be operated with all the filters in the extreme cut position. Experimentation will illustrate the fantastic versatility and range of the equalizer circuit. 14. The pilot light indicates when power is applied to the amplifier. 15. The DIN connector is the recepticle for plugging in the remote footswitch. 16. The three wire line cord has been provided for your protection and should be connected to the proper line voltage as indicated on the back panel. DO NOT REMOVE GROUND PIN ON PLUG. 17. The fuse is located within the cap of the fuse holder and should be replaced with one of the proper value if it should fail. It is necessary that the proper value fuse be used to avoid damage to the equipment and to avoid voiding the warranty. Models that have circuit breakers can be reset by depressing the red button. If the breaker trips repeatedly, take the unit to a qualified service center for inspection. 18. The line power switch is of the three position type with the center position being OFF. The three position switch has two ON positions which are used to ground the amplifier properly. One of the on positions will yield the least hum or popping when the instrument is touched and this is the position that should be used. 19. The line cord retainers on the rear panel are provided for your convenience in storing the AC line cord during transport of the unit. 20. The two speaker output jacks of the F-800 are designed to deliver slightly more than 400 WATTS RMS into a two ohm load (28.3 VRMS), with the proper line voltage as indicated on the power amp. Each output jack is designed for a four ohm load. These jacks are parallel internally, resulting in the rated two ohm load. NEVER OPERATE THE AMPLIFIER WITH LOADS LESS THAN TWO OHMS. Because this amp is...
