Exposure to extremely high noise levels may cause permanent
hearing loss. Individuals vary considerably in susceptibility to noise-
induced hearing loss, but nearly everyone will lose some hearing
if exposed to sufficiently intense noise for a period of time. The
U.S. Government’s Occupational Safety and Health Administration
(OSHA) has specified the permissible noise level exposures shown
in the following chart.
According to OSHA, any exposure in excess of these per-
missible limits could result in some hearing loss. To ensure against
potentially dangerous exposure to high sound pressure levels, it is
recommended that all persons exposed to equipment capable of
producing high sound pressure levels use hearing protectors while
the equipment is in operation. Ear plugs or protectors in the ear
canals or over the ears must be worn when operating the equip-
ment in order to prevent permanent hearing loss if exposure is in
excess of the limits set forth here:

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. A footswitch 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.

20. AC LINE IN: Firmly insert the supplied AC
power cord into this socket until it is fully seat-
ed. Plug the male end of the cord into a
grounded AC outlet. DO NOT DEFEAT THE
GROUND PRONG OF THE AC PLUG!
21. BAL. OUT: This jack supplies a line level
signal for connection to a house mixing board,
recording console or external amplifier. The sig-
nal level at this jack is governed by the Post/Pre
switch (#23).
22. GND/LIFT: Use this switch to lift the ground
connection at the Bal. Out jack to help eliminate
hum in the Bal. Out signal.
23. POST/PRE: The signal at the Bal. Out jack
(#21) can be set to either Pre or Post-EQ with
this switch. With the swi
tch in the OUT position,
the signal at the jacks is Pre-EQ. This is a direct
output not affected by any EQ or boost settings.
With the switch depressed, the signal is Post-
EQ and is controlled and modified by the tone
controls and the effects loop.
24: TUNER OUT: This jack is provided for con-
nection to an electronic tuner and is always
“live,” even when the Mute switch (#3) is
engaged. This allows for “silent tuning” as well
as a monitor feed which stays hot even when
the house mix is muted.
25. SPEAKERS: These output jacks supply
speaker-level power to the speaker cabinet.
The rated power output is 1300 watts rms
into 4 ohms or 2500 watts rms into 2 ohms
(minimum load).
WARNING: Use speaker cables to make
the connections. Do not use instrument
cables as they may overheat.
Pin 1+ = hot
Pin 1– = return
26. CIRCUIT BREAKER: The SVT-8 PRO
employs an AC line circuit breaker to
help pro-
tect against damages due to excessive current
demands. If the amplifier stops working, check
the circuit breaker.
27: POWER AMP IN: This jack connects an
external preamp directly to the power amp.
When using an external source, connect the
output of the source to this jack by means of a
shielded signal cable to feed the signal into the
power amp section. The internal signal is dis-
connected when a connector is inserted into
this jack.
28. PREAMP OUT: Use this jack to send a sig-
nal from the internal preamp to an auxiliary
power amplifier, mixing console, monitor sys-
tem, or
house PA system. The signal at this
jack is post-EQ.
29. EFFECTS LOOP RETURN: When using
an external signal processor, connect the out-
put of the device to this jack by means of a
shielded signal cable.
30. EFFECTS LOOP SEND: When using an
external signal processor, connect this jack to
the input of the device by means of a shielded
signal cable.
31. FOOTSWITCH: Connect a two-button
(ring/tip/sleeve) footswitch to this jack to control
the Power Reduction and the Mute functions.
(Mute = tip/sleeve; Power Reduction = ring/
sleeve.)
NOTE: A footswitch may be purchased at
your local Ampeg Dealer or ordered directly from
LOUD Technologies Inc. Be sure to ask for
model #AFP2.
IMPORTANT: This unit employs forced air
cooling by means of an internal fan. The
rear and side ventillation slots must remain

When mounting the unit in a rack make sure
there is ample room for proper air circulation.
The rack must be constructed and positioned
in such a manner to allow proper air flow and
the exhausting of hot air away from the rack
at all times.

Rack Mounting
When mounting the SVT-8 PRO into a rack, the four bottom feet should be removed to maintain the two rack space height of the ampli-
fier. Be sure to keep the feet and their attachment bolts for future use. If the feet are reinstalled, never use screws which will protrude
farther into the amplifier than the original hardware!
The rack must be a high quality enclosure capable of securely supporting the weight of the amplifier. Tighten the mounting screws
securely through the amplifier’s face plate, into the rack rails. Check the rack and mounting screws occasionally to ensure a continual-
ly safe and secure installation. Additional rack ears are provided on the rear of the amplifier for connection to an additional support brack-
et. It is highly recommended that this additional support be used when rack mounting the amplifier.

Troubleshooting
In the unlikely event that your SVT-8 PRO should malfunction, take a few minutes to troubleshoot it before you call
for service. You can save yourself time and 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 lead 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 (see page 2). Regular maintenance and cleaning should be performed on a routine basis to prolong the ampli-
fier’s useful life.
