Peavey TNT 130

THE FRONT PANEL
On/Ofl Switch
The on/oif power switch is a two position rocker-type and should present no problem In operation. In the
on position, a red LED indicator will Illuminate showing that power is oeing supplied to the unit. NOTE: WHEN
THE UNIT IS TURNED ON THE DDT" COMPRESSION LED MAY MOMENTARILY ILLUMINATE.
ALTHOUGH WE RECOMMEND THAT THE GAIN CONTROLS (PRE AND POST GAIN) SHOULD BE AT
THEIR ZERO POSITIONS BEFORE THEPOWER SWITCH IS TURNED ON, THE OCCASIONALLY LIGHTING
OF THE DDT' - LED IN THIS INSTANCE SHOULD BE CONSIDERED NORMAL.
Ground Switch
The ground switch is a 3-position rocker-type which, in mostappllcations.should be operated in itscenter
or zero position. You may encounter some situations where an audible hum and/or noise will come from the
loudspeaker. If this situation arises, posilion the ground switch toeitheroositive or negative or until the noise is
eliminated NOTE: SHOULD THE NOISE PROBLEM CONTINUE. CONSULT YOUR AUTHORIZED PEAVEY
DEALER. THE PEAVEY FACTORY OR QUALIFIED SERVICE TECHNICIANS DO NOT UNDER ANY
CIRCUMSTANCE. REMOVE THE GROUND PIN ON THE MAINS (POWER) CABLE NOTE: The Ground
Switch is not functional on export units.
DDT'" Compression
The TNT* 130 utilizes our patented DDT’" (Distortion Detection Technique) compression circuit to effectively
eliminate the possibility of distortion (square waves) from occuring within the power amp
As mentioned in the On/Off Switch section, the DOT 1 * LED will sometimes illuminate when the unit is first
turned on and this should be considered normal. The DDT" LED will also occasionally illuminate to indicate
tnat the DOT" circuit is automatically engaging to prevent distortion. NOTE; IF THE DDT" LED REMAINS
CONSTANTLY LIT WHILE YOU ARE PLAYING. THIS IS AN INDICATION THAT THE GAIN (VOLUME)
CONTROLS AND/OR EQUALIZATION CONTROLS ARE SET IN POSITIONS THAT ARE MAKING THE
POWER AMP OVERWORK. ALTHOUGH THE DDT". IN MOST CASES. WILL PREVENT SPEAKER DAMAGE
AND/OR FAILURE WE RECOMMEND THAT THE GAIN/EQUALIZATION CONTROLS BE READJUSTED
UNTIL THE DDT'" LED WILL ILLUMINATE PERIODICALLY
Patch Section
The patch section consists of tv/o jacks labeled preamp output and power amp input. Primarily the preamp
output and power amp input jacks are used for patching effects devicesand signal processing equipment "in¬
line" with the TNT'" 130. Most devices such as flangers, chorus, tape/analog/digital delays or gain devices such
as external compressors can be used within the effects loop. The preamp output level is approximately 1 volt
RMS and is a relatively low impedance — 1000 ohms. To utilize this effects loop, use a high duality, shielded
patch cord and plug one end into the preamp output and the other end into theexternal device input. To return
the processed signal to the TNT'" 130. use a second high quality shielded patch cord and plug one end into the
external unit output and the other end of the patch cord Into the power amp input
Since this method of using an effect places the device alter the preamp/ equalization and before tne power
amp you will have a greater degree of control over the sound quality of the device or signal processing unit
The preamp output can also be used to send the signal of the instrumem/ preamp to mixing and recording
consoles. For this method use a high quality, shielded patch cere anc make the connection from the TNT"
130’s preamp output to the desired channel of the mixer or loan auxiliary device where the signal is not to be
returned to the power amp input. With this method of sending your instrument signal or auxiliary device, you do
not have to utilize the power amp input as the signal will automatically feed the power amp section

The Crossover
The TNT'" 130 is equipped with a built-in variable crossover network which gives thebassist/keyboardist
the basic tools to perform the bi-amp function. To achieve the bi-ampfunction the musician must acquire one
(1) additional power amp and one (1) additional loudspeaker and enclosure. For a perfect companion system
we recommend our XC-400'" or M-3000" power amps and the 118D’" low frequency enclosure. To utilize this
recommended bi-amp system, use a short, high quality, shielded patch cord (1 - 3 feet in length) and make the
connection from the high output of the crossover section to the power amp input of the TNT'" 130 Use a longer,
high quality, shielded patch cord to make the connection from the low output of the crossover section to the
external power amp input Use a high quality, unshioldod patch cord to make the connection from the external
power amp's outputs to the low frequency enclosure.
We recommend that, for the optional equipment and bi-amp procedures mentioned above, the crossover
point be established somewhere around 175 Hz to 300 Hz. This method now allows the TNT 1 " 130 to reproduce
only those frequencies above the crossover point while the external power amp/enclosure will reproduce
frequencies below the crossover point. NOTE: THIS IS ONLY ONE EXAMPLE OF THE BI-AMP OPERATION
OF THE TNT'" 130. IF YOU ARE NOT FAMILIAR WITH THIS OR ANY OTHER BI-AMP TECHNIQUE, WE
RECOMMEND THAT YOU CONSULT YOUR AUTHORIZED PEAVEY DEALER.THE PEAVEY FACTORY OR
QUALIFIED TECHNICAL PERSONNELTO OBTAIN OTHER PERTINENT INFORMATION ON YOUR BI-AMP
SYSTEM.
Equalization Section
The TNT'“ 130s equalization section contains six individual controls for shaping and contouring the
instrument signal Please be aware that the TNT’" 130 employs active circuitry which allows you to have
accurate cut and boost capability of highs (treble), iows (bass) and the vital middle frequencies. Because these
controls are active, tne low. mid. high and presence controls can reproduce the ‘‘natural" sound of the
instrument without undue coloration by simply placing them at their 12 o'clock or zero positions. Rotating
these controls to their center positions is actually an excellent place to start when you begin to search for new
tonalities and sounds. NOTE: WHEN THE LOW. MIDDLE. HIGH AND PRESENCE CONTROLS ARE PLACED
AT THEIR 12 O'CLOCK OR ZERO POSITIONS. THERE WILL BE CORRESPONDINGLY LITTLE EFFECT ON
THE INSTRUMENTS SIGNAL AND THE CONTROLS LABELED SHIFT AND BANDWIDTH WILL HAVE NC
EFFECT BECAUSE THE MIDDLE HAS BEEN SET FLAT".
The Presence Control
The presence control should be used to adjust the extreme high end (treble) of the bass guitar or keyboard
signal. For less high end response lotate the presence control counlerclockwise (0 to-12dB) until achieving
