14.FAN: The temperature controlled, vari- able speed fan forces 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 pow- ered up.

15.FUSE: This protects the unit from dam- age due to overload conditions or power line surges. If the fuse blows, replace it only with the same size and type.

16.AC LINE IN: Firmly insert the supplied AC power cord into this socket until it is fully seated. Plug the male end of the cord into a grounded AC outlet. DO NOT

DEFEAT THE GROUND PRONG OF THE AC PLUG!

17.SPEAKER OUTPUTS: Use these jacks to connect the amplifier to your speaker(s) using cables terminated with 1/4” connectors. 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:

Cabinet	# of	Total
Impedance	Cabs	Impedance
8Ω	2	4Ω
16Ω	2	8Ω
16Ω	4	4Ω

18.POWER AMP IN: This mono jack allows you to feed the preamp output of another amplifier to the input of the SVT- 350H’s internal power amp. This bypasses the preamp circuitry of the SVT350H.

19.PREAMP OUT: A post-EQ signal may be taken from this jack and sent to the house mixing board, recording console or external power amplifier.

20.EFFECTS RETURN: To use an exter- nal effects device, connect the OUTPUT of the device to the Return jack using a shield- ed cable. This feeds the processed signal into the Master section of the SVT-350H.

21. EFFECTS SEND: Connect the output

from the Send jack to the INPUT of your

effects using shielded cable. This sends a

post-EQ signal to your effects.

22. -20dB SWITCH : This control adjusts

the output level at the Balanced Line

Output jack (#24). The control works inde-

pendently from the front panel Master con-

trol. Depressing the switch activates the

20dB pad. The result is a signal that is

more compatible with the microphone

inputs on a mixer.

23. PRE/POST SWITCH: You can select

either Pre or Post EQ for the signal at the

Balanced Out jack (#24) 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 depressed,

the signal is Post-EQ and is controlled and

modified by the tone controls, Graphic EQ,

and Effects Loop.

24. BALANCED OUTPUT: This XLR-type

connector supplies a balanced preamp out-

put signal for connecting to a house mixing

board, recording console or external ampli-

fiers with balanced inputs. The signal can

be set to Pre or Post EQ by the back panel

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.	200W @ 8 OHMS

adjusted for either mic or line type inputs

using the -20dB switch (#22).
