PICKUPS AND ELECTRONICSPICKUPS AND ELECTRONICS TC PreampsThe TC series preamplifiers are designed to improve the performance of electric instruments by increasing the signallevel, modifying tonal quality with a wide range of options and decreasing the treble losses in the cable.All TC preamps can be used in the unboosted mode to provide equal amplification of all audio frequencies. Theboosted modes allow tonal changes ranging from simple treble boost to a midrange spectrum shaping specificallydesigned to overdrive amplifiers to their best distortion sounds.These preamplifiers are hand made from discrete components (no I.C.’s) for very low noise levels, outstandingdistortion characteristics, and very long battery life. They are rugged, reliable, easy to install, and in most cases do norequire modifications to the instrument. Although we recommend shielding the control cavity for optimum performance,the internal shielding of these preamps will provide very low hum levels even in unshielded installations.The following examples explore some of the possible uses of these preamps.USING THE TC PREAMP WITHOUT BOOSTTCTC9 voltBATTERYs t e r e oj a c kyellow (input)To Volume Controlor Selector SwitchblackGroundred red (+9V)Boost Lead(use shrink tubingor electrical tape)blackgreen (output)This wiring increases the instrument signal level 2x (TC5), 4 x (TC3), or 8x (TC1)without distortionThe battery is switched ON when the mono plug is plugged into the stereo jack.TCTC BYPASS SWITCH(DPDT)yellow (input)green (output)1M-ohm470K-ohmTo Volume Controlor Selector SwitchTo OutputJack50K-ohmto250K-ohmAUDIOgreen (output) To OutputJackPreamp bypass switch or output level control can be wired as follows:The resistors on the bypass switch minimize switching noises.The level control will vary the signal from 0 to the maximum output of the preamp.From Pickupor Selector Switch TCTCyellow (input) red +9VBoost LeadblackVolumeA250K-ohmAUDIOToneA250K-ohmAUDIO27K-ohmgreen.047mfdTo OutputJackGroundFor maximum control of pickup tonality the TC preamplifiers can be used to isolate the pickup from thetone and volume controls.The battery is switched ON when the mono plug is plugged into the stereo jack.From Pickupor Selector Switch |
