Control The presence control should be usec to adjust tne exireme high end treble of the bass guitar or keyboard signal For less high end response rotate the presence control counterclockwise to 12 dB until ac EQUALIZATION 130 the desired high end rolloff boost high end response of the preamp rotate the control clockwise 0 to 12 dB The boost portions of this control are very effective for adding an edge to contemporary neck slapping and string popping techniques employed by bassisis or for accentuating the high end of electronic keyboards See tone setting charts for further examples The High Control The nigh control is similar in operation to the presence control but is placed atalower frequency point AS with the presence control less high end response is obtained through counterclockwise rotation 0 to 15 dB while increaged treble response occurs in the ranges from 0 to 15 dB See the tone setting charts for further exemples The Mid Shift and Bandwidth Controls Parametric Equalizer The mid shift and bandwidth controls together determine the tonal response of the vital mid band region We choose to uso the word vital to describe the mid frequencies because proper uso of this frequency region and does make the difference between a good sound and a great one Thorough experimentation with Inese controls will rapidly demons

KING 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 LED WILL ILLUMINATE PERIODICALLY Patch Section The patch section consists of two jacks labeled preamp output and poweremp input Primarily the preamp output and power amp input jacks are used for patching effects devices and signal processing equipment in line with the TNT 120 Most devices such as flangers chorus tape analog digital delays or gain devices such as external compressors 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 quality shielded patch cord and plug one end into the preamp output and the other end into the external device input To return the processed signal to the TNT 130 use a second high quality shielded patch cord and plug one endinto the external unit oulput and the other end of the patch cord Into the power amp Input Since this method of using an effect places the device affer tne preamp equalization and before the 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 instrument preamp to mixing and recording consoles Far this method use a high quailty shielded pat

7. TNT 130 Operating Guide INTRODUCTION AND GENERAL DESCRIPTION Congratulations on your purchase of the Peavey TNT 130 bass amplification system After reading this owner s manual you will have a better understanding of the operating principles of the system A thorough understanding of these instructions will also help you to achieve many varied tonal settings The TNT 130 isa highly advanced 130 watt bass system utilizing the latest active equalization circuitry built in variable crossover network patching facilities a tuned and ported enclosure and a very efficient 15 loudspeaker As an option the 130 is available with a premium Black Widow Super Structure transducer model 1502 4 The TNT 130 also employs our patented DDT Distortion Detection Technique compression circuit U S Patent 44 318 053 which automatically detects the onset of clipping distortion et the power amp Not only does this novel circuit help prevent speaker damage failure it also aids in reproducing the ultra clean sounds for today s bass and keyboard styles As with any sophisticated piece of equipment there are some operating principles concerning the input stage gain controls equalization and patching facilities which must be understood to obtain the best tonal results Please read and understand this manual and keep it handy for future reference TNT 130 SPECIFICATIONS POWER AMPLIFIER SECTION RATED POWER amp LOAD 130 W AMS into 4
