1. TNT 100 WNERS MANUAL The TNT is the successful result of our efforts to design and produce a completely professional single unit bass amp in the low price range This new amp is powered by our rugged 45 watt RMS 5 THD electronic chassis that features some new and unique tone circuitry previously unavailable even in the most expensive amplifiers Our TNT features a full set of conventional volume bass and treble con trols plus the new middle shift and middle controls The middie and middle shift controls work in con junction to vary the amp s response in the vital mid frequency band The middle control varies the blend of the mid frequencies while the middle shift control determines the range of mid frequencies affected by the middle control These two mid controls enable the TNT to produce an extremely wide range of response curves extending from the low booming bass sound to the funky penetrating tight sounds so popular in today s music We have included a master volume control to enable the preamp to be over driven tor various distortion and sustain effects and also provide a method for controlling the amp s sen sitivity for maximum performance in the recording studio The rugged output circuit of the TNT uses a pair of 15 amp high energy power devices coupled to a large aluminum heatsink for maximum durability under road conditions The single heavy duty 15 speaker is securely mounted in a2. rugged 3 4 inch ported cabinet and is covered with 34 ounce Tolex to stand up under constant use The power output and tremendous penetration of the TNT is adequate for any playing situation where extremely high volume levels are not required This professional bass amp is superior to anything in its price category Comparison will demonstrate its un matched value 1 The input jacks are arranged in a unique circuit that allows a wide range of input levels to be handled by the TNT Input one is the high gain input and should normally be used when plugging in your in strument Input two is the low gain input and should be used if the signal from your instrument tends to overload distort the preamp It two instruments are used and both jacks one and two are used the cir cuit automatically balances the gain of the two inputs so that the sensitivity of both are identical 2 The volume control serves to control the gain of the preamp This preamp circuit makes possible ex ceptional gain and input impedance while allowing the amplifier to provide tremendous dynamic range 3 The treble control is part of an electronic crossover and may be considered as a level control for treble frequencies These variable feedback type tone controls are capable of providing a out as well as a boost Because the treble control is a volume control for treble frequencies it is good practice to operate it close to fully clockwise for maximum bene
3. fit and volume Experimentation will allow the musician to find the level that works best for his preference in tone 4 The bass control is also part of an electronic crossover that forms the tone circuit and works as a level for the bass frequencies The bass control provides for both a boost and a cut in bass response sels a a a ala 94 Jagbododoe e Like the treble control the bass should be run near its full clockwise position for maximum volume from the amp 5 The middle control enables the musician to tailor the vital mid range response Experimentation with the unique middle circuit will show that it is much more effective than conventional circuits 6 The middle shift control enables the player to select the particular frequency range that he wants to cut in the midrange spectrum This means that he can change and vary the total sound characteristics of the amplifier simply by turning a single control 7 The master volume control is very useful for ob taining a number of effects The most common use of this control is for obtaining overdrive and sustain at low sound levels Another valuable use for this control is for controlling the response and noise of the amp in a recording studio The master volume control is the final gain deter mining element before the signal is fed into the out put amplifier and could more accurately be called a sensitivity control To obtain maximum overd
