1.INPUT: Connect your bass guitar here by means of a shielded signal cable.

2.-12dB:This switch, when depressed, attenu- ates the input signal by 12dB. Attenuation allows the Gain control (#4) to be used over a larger por- tion of its range. If clipping is indicated with the Gain way down, attenuation is needed.

3.MUTE: This switch, when depressed, mutes all outputs except the Tuner Out (#24, rear panel). This allows you to use an electronic tuner without having to adjust any levels or turn down your house sound.Afootswitch may be used to control the mute function as long as this switch is in the out position.

4.GAIN: This controls the gain of the preamp. Adjust this control until the Peak LED (#5) flickers on strong signal peaks (but is not illuminated con- stantly while playing).

5.PEAK: This LED illuminates when the signal level into the preamp or power amp nears clip- ping. Adjust the Gain control (#4) until a strong signal from your instrument causes this LED to flicker with the Master control (#16) set low.

NOTE: If the LED flickers frequently with the Gain at a low setting, use the -12dB switch (#2) to attenuate the input signal and readjust the Gain.

6.ULTRA LOW: Use this five-position rotary switch to optimize the low end response as fol- lows:

1:Off – flat low frequency response

2:Sub Cut – reduces frequencies below the bass range to protect your speakers

3:Low Cut Classic – provides a low cut equal to our original SVT Classic amplifier

4:Ultra Low Classic – contours the sound to emphasize the low end just like our original SVT amplifier

5:Ultra Low Modern – provides a substantial low end boost

7.ULTRA HIGH: This switch, when depressed, adds about a 16dB boost to the high frequencies around 8kHz, depending on the setting of the Gain control.

8.BRIGHT: This switch, when depressed, adds a 6dB boost to the high frequencies at 3kHz.

9.BASS: Use this control to adjust the low fre- quency output level. This control provides +17/-13 dB at 20Hz.

10.MIDRANGE: Use this control to adjust the midrange frequency output. This control provides +/-20dB at the frequency selected by the adjacent Frequency control (#11).

11.FREQUENCY: Use this control to select the center frequency for the Midrange control (#10) as follows:

1:220Hz

2:450Hz

3:800Hz

4:1.6kHz

5:3kHz

12.TREBLE: Use this control to adjust the high frequency output level. This control provides +18/ -20dB at 7kHz.

13.POWER REDUCTION ON: This LED illumi- nates when the Power Reduction function is active.

14.POWER REDUCTION DRIVE / PULL ON: This control, when engaged, determines the sig- nal level sent to the simulated tube power amp section. This control works in conjuntion with the other preamp controls in determining how hard the “power amp” is driven. The Power Reduction is engaged when this control is pulled out slightly until it clicks.

15.POWER REDUCTION POWER: This control sets the output level of the simulated tube power amp section. This allows you to obtain the desired amount of “tube power amp growl” at any volume.

16.MASTER: Use this control to adjust the over- all level of the amplifier.

17.LIMIT: The SVT-8 PRO employs an internal limiter to help prevent overdriving the power amp. This LED illuminates when the Limiter is activat- ed, indicating that the levels are near clipping. Reduce the Master control (#16) if this LED illu- minates continuously while playing.

18.FAULT: This LED illuminates when faulty con- ditions cause the amplifier to protect itself against damages. If this LED should illuminate while play- ing, turn the amplifier off, wait ten seconds, then turn the amplifier back on. If the Fault LED con- tinues to illuminate refer the amplifier to a qualified Ampeg service center.

19.POWER: Use this switch to turn the amplifier on (top of the switch depressed) and off (bottom of the switch depressed). The adjacent LED illu- minates when the amplifier is turned on.
