22. CROSSOVER BALANCE: This adjusts the relative level between the low and high frequency biamp signals when using the amplifier in the biamp mode. 23. 9-BAND GRAPHIC EQ: These sliders control the amplitude of the signal at the frequency indicated below each control. The center position of each control is flat: sliding the control upward will increase the output signal level of that frequency; sliding the control downward will decrease it.
The Graphic EQ can be used in two ways: 1) To fine tune your sound, make small adjustments at the desired frequencies and leave the EQ on throughout the entire session. (This is great for adapting to varying room acoustics when going from club to club, etc.) 2) For a completely different sound, make larger adjustments and only activate the EQ when you want a �second channel� sound (such as during bass solos).

15. GRAPHIC EQ: This switch, when depressed, enables the 9-band Graphic EQ (see #23 and 24). The sound of your bass will only be affected by the settings of the EQ slider controls when this switch is depressed, or when a footswitch is pressed. (A footswitch will override the front panel switch. Please refer to #38, rear panel.) 16. LINE OUT LEVEL: This controls the strength of the signal at the Line Out jacks (#40,41,44,45, rear panel). 17. EFFECTS BYPASS: This switch, when depressed, bypasses the Effects Loop. (A footswitch will override the front panel switch. Please refer to #38, rear panel.) 18. LIMIT DEFEAT: The SVT-4 PRO employs internal limiter circuits to help keep the power amplifier�s output clean at extreme volume levels. (All amplifiers may begin to clip their output signals as they approach maximum output levels, resulting in potentially speaker-damaging distortion.) These circuits may be defeated by depressing this switch, which may result in an increase in output power but with the possibility of distortion. Use discretion whenever playing with the Limit circuits defeated. 19. MASTER: This controls the overall output level of the amplifier. For the best results, adjust the Gain control as directed (see #5) and use this control to obtain the desired volume level. 20. LIMIT LED: This LED will flash any time the internal limit circuit is called upon to keep the amplifier�s output signal clean. This indicates that the amplifier is nearing full output and the limiter is keeping it from clipping the output signal. 21. CROSSOVER FREQUENCY: This sets the crossover point between the Biamp High and Biamp Low Outputs when using the amplifier in the biamp mode. (See page 13.)

24. LEVEL: This is the output volume control for the Graphic EQ and only affects the signal when the EQ is engaged. If the EQ�d signal is too soft, slide the Level control up; if it�s too loud, slide the control down. 25. POWER LED: This LED illuminates green when the Power switch (#27) is depressed. 26. ACTIVE LED: This LED illuminates when the Graphic EQ switch (#15) is depressed. 27. POWER: This heavy-duty rocker switch applies AC power to the amplifier: the amp is ON when the top of the switch is depressed, OFF when the bottom of the switch is depressed.
