Important Safeguards and Precautions

All Ampeg products are designed for continuous safe operation, as long as common sense is used and

steps are taken to help avoid certain problems. Abiding by the following rules can help prevent damage to

your amplifier, yourself and others.

•The amplifier is equipped with a three-pronged AC power cord. To reduce the risk of electrical shock,

NEVER remove or otherwise attempt to defeat the ground pin of the power cord.

•Connect the amplifier ONLY to a properly grounded AC outlet of the proper voltage for your amp.

•Avoid sudden temperature extremes, rain and moisture. Also, avoid sudden and intense impact. (If

the unit has been subjected to any of the preceding abuses, have it looked at by an authorized ser-

vice center.)

•NEVER set the amplifier on a support that might give out under its weight.

•Always keep the total speaker impedance at or above the rated load.

•Unplug the amplifier before cleaning it. NEVER spray liquid cleaners onto the amplifier. Wipe it with

a slightly dampened, lint-free cloth to remove dirt and film.

•Don’t use the amplifier if it has sustained damage to the chassis, controls, or power cord. Refer the

unit to an authorized service center for inspection.

•Amplifiers capable of producing high volume levels are also capable of inflicting permanent hearing

loss or damage, if the exposure to such levels is prolonged. Such damage is progressive and irre-

versible!

The Front Panel Controls and Their Use

4 5 6 7 8 103 12 13 14 1521 9 11

1. INPUT: Connect your bass here

using a standard shielded instrument

cable.

2. 15dB PAD: When engaged, this

switch cuts the input signal level by

15dB, allowing you to set the Gain

control (#4) for the best signal to noise

ratio. (If your bass has high-output

pickups or active electronics, you

should use the Pad.)

3. PEAK LED: This LED lights when-

ever any preamp stage is near clip-

ping. Adjust the Gain control (#4) until

a strong signal from your bass causes

this LED to flicker.

4. GAIN: This serves as the input level

control for the amplifier. For the best

signal to noise ratio, set this control so

the Peak LED (#3) flashes when you

hit your strings hard.

NOTE: If the Peak LED stays on with

the Gain at a low setting, use the 15dB

pad (#2) to cut the input signal, then

readjust the Gain.

5. BASS: The primary low frequency

control. This knob allows for a range of

8dB of cut or boost at 50Hz.

6. ULTRA-MID: The primary midrange

control. Rotate the knob to the left of

center for a “contoured” sound (more

distant, less midrange output) or to the

right of center for a sound which really

cuts through.

7. TREBLE: The primary high frequen-

cy control. This knob allows for a range

of 12dB boost or 19dB of cut at 5kHz.

8. MASTER: Set the overall output

level of the amplifier with this control.

The Effects Loop and Balanced Out

(#22-26) are not affected by the Master

control.

9. LIMITER SWITCH: The amplifier

uses an internal Optocoupler Limiter to

help keep the power amp’s output

“clean” at extreme volume levels. (All

amplifiers may begin to clip their out-

put signals as they approach maxi-

mum output levels, resulting in poten-

tially damaging distortion.) To engage

the Limiter, press in the Limit switch.

Playing at full power with the Limiter off

will give you increased output power,

but the sound may be distorted. Use

discretion when playing without the

Limiter.

10. LIMIT LED: This LED will flash any

time the internal limiter circuit is called

upon to keep the amplifier’s output sig-

nal clean. This shows that the amplifi-

er is nearing full output and the limiter

is keeping it from clipping the output

signal.

11. EQ ON SWITCH: Press this switch

IN to activate the Graphic EQ.

12. EQ ON LED: This LED lights when

the Graphic EQ is active.

13. GRAPHIC EQ: These slide con-

trols allow you to adjust the output of

the frequencies shown above each

control. The center position of each

control is flat (no boost or cut).

14. POWER ON LED: This LED lights

when the POWER switch (#15) is ON.

15. POWER SWITCH: This heavy-

duty rocker switch applies the power to

the amplifier: the amp is ON in the up

position, OFF in the down position.

16. FAN: This temperature controlled,

variable speed fan draws cool air into

the amplifier, forcing heat out through

the exhaust vents (also on the rear

panel, between the speaker jacks and

the power amp in jack). Never block the

vent holes or the fan openings.

NOTE: It is not uncommon for the fan to

remain off when the amplifier is first

powered up.

17. FUSE: This protects the unit from

damage due to overload conditions or

power line surges. If the fuse blows,

replace it only with the same size and

type.

18. AC LINE IN: Firmly plug the sup-

plied AC power cord into this socket,

pushing it in until it is fully seated. Plug

the male end of the cord into a ground-

ed AC outlet. DO NOT DEFEAT THE

GROUND PRONG OF THE AC PLUG!

19. SPEAKER OUTPUTS: Use these

jacks to connect the amplifier to your

speaker(s) using cables terminated with

1/4” plugs. Always use high-quality

speaker cables for these connections.

NOTE: When connecting multiple

speaker cabinets to the amplifier,

keep the overall impedance at or

above four ohms! The following chart

shows the total impedance load when

connecting speaker cabinets in parallel:

20. POWER AMP IN: This mono jack

allows you to feed the preamp output of

another amplifier to the input of the

internal power amp. This disconnects

the SVT’s preamp.

21. PREAMP OUT: A post-EQ signal

may be taken from this jack to be sent

to the house mixing board, recording

console or external power amplifier.

22. EFFECTS RETURN: To use an

external effects device, connect the

OUTPUT of the device to the Return

jack using a shielded cable. This feeds

the processed signal into the amp’s

Master section.

23. EFFECTS SEND: Connect the out-

put from the Send jack to the INPUT of

your effects using shielded cable. This

sends a post-EQ signal to your effects.

24. -20dB SWITCH : This control

adjusts the output level at the Balanced

Line Output jack (#26). The control

works independently from the front

panel Master control. Pushing the

switch in activates the -20dB pad,

allowing use of microphone inputs on a

mixer without overdriving the inputs.

25. PRE/POST SWITCH: You can

select either Pre or Post EQ for the sig-

nal at the Balanced Out jack (#26) with

this switch. With the switch in the OUT

position, the signal at the jacks will be

Pre-EQ. This is a direct output not

affected by any EQ or boost settings.

With the switch in, the signal is Post-EQ

and is controlled and modified by the

tone controls, Graphic EQ, and Effects

Loop.

26. BALANCED OUTPUT: This XLR-

type connector supplies a balanced

preamp output signal for connecting to

a house mixing board, recording con-

sole or external amplifiers with bal-

anced inputs. The signal can be set to

Pre or Post EQ by the back panel

Pre/Post switch (#25). The level can be

adjusted for either mic or line type

inputs using the -20dB switch (#24).

IMPORTANT NOTE ABOUT CERTAIN EXPORT

UNITS: In some areas 1/4” speaker jacks are not

acceptable for use on amplifiers capable of high out-

put power levels. For this reason the Speaker jacks

on your amplifier may resemble the illustration to the

right. Connect the amplifier to your speaker(s) using

cables rated for very high output power, terminated

with the appropriate connectors.

Some Suggested Settings

JAZZ:

ROCK:

COUNTRY:

FUNK “POPPING:”

The setting of the Gain and Master controls depend on your bass, on your

playing style, and on how loud you want it! The Graphic EQ can be used

to compensate for room acoustics, to “fine tune” your sound, and as a

“second channel” to be kicked in when needed for soloes and riffs.

Troubleshooting

In the unlikely event that your SVT-GS Gene Simmons Punisher should stop working properly (or just stop working), take

a few minutes to troubleshoot it before you call for service. You can save yourself a lot of time and sometimes money by

doing it yourself, and often the cure for the problem is something quite simple.

If the problem isn’t covered above, or if the steps led you here, then contact your Ampeg dealer for service informa-

tion. Also, you should refer your amp for servicing if it gets dropped, has liquid spilled into it, or sustains damage to its

power cord.
