No user serviceable parts inside. Refer Servicing to qualified service personnel. TNT 160 WARNING: TO PREVENT ELECTRICAL SHOCK OR FIRE HAZARD. DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE. BEFORE USING THIS APPLIANCE, READ THE OPERATING GUIDE FOR FURTHER WARNINGS. FRONT PANEL 4 13 17 18 1 2 3 5 6 7 8 9 10 11 12 14 15 16 19 HIGH GAIN INPUT (1) Used for most electric basses. It is 6 dB louder than the Low Gain Input. LOW GAIN INPUT (2) Provided for instruments that have extremely high outputs, which can result in overdriving (distorting) the High Gain input. If both inputs are used simultaneously, the output levels are the same (both are Low Gain). PRE GAIN (3) Controls the input volume level of the channel. BRIGHT SWITCH (4) Provides a preset boost (+/-8 dB) to treble frequencies. To activate, depress the switch to its “in" position. PUNCH SWITCH (5) Provides a preset boost (+8 dB) to midbass frequencies. To activate, depress the switch to its “in” position. POST GAIN (6) Controls the overall volume level of the amplifier. The final level adjustment should be made after the desired sound has been achieved. LOW FREQUENCY EQ (7) An active tone control (shelving type, +/- 15 dB) that varies the low frequency range. CAUTION: Excessive low frequency boost causes greater power consumption and increases possibility of speaker damage. 9-BAND GRAPHIC EQ (8) Provides +/- 15 dB equalization at each center frequency. HIGH EQ CONTROL (9) An active tone control (shelving type, +/-15 dB) that varies the high frequency range. CROSSOVER FREQUENCY CONTROL (10) Adjusts the frequency of the crossover dividing network. CROSSOVER FUNCTION The amplifier is equipped with a variable electronic crossover network, which allows its use as part of a biamplified system. A “biamped” system is one in wh ch low frequency and high-frequency signals are reproduced by separate power amplifiers and speaker enclosures. Biamped systems provide increased headroom, greater clarity, and superior power handling. An effective biamplified system may be created using the amplifier with another Peavey product, the 210HP powered enclosure. To establish this system, connect the Cross-over High output to the input of the 21OHP. Connect the Crossover Low output to the amplifier’s Power Amp input. High quality shielded cables should be used for these connections. The Crossover Frequency control should be set at 250 to 300 Hz. LOW RANGE OUTPUT (11) Provides a post-crossover low range signal. Signal level is adjusted by the Post Gain Control. HIGH RANGE OUTPUT (12) Provides a post-crosssover high range signal. Signal level is adjusted by the Post Gain Control. Signals which appear at this jack may be processed by the chorus circuit. CHORUS IN/OUT SWITCH (13) Is used to activate/defeat the chorus circuit. To activate the circuit, depress the switch to its “in” position. NOTE: Chorus footswitch “overrides” push switch. RATE CONTROL (14) Controls the sweep rate (frequency) of the chorus effect. DEPTH CONTROL (15) Controls the depth (intensity) of the chorus effect. PREAMP OUT/POWER AMP IN (16) These jacks are provided for in-line patching of effects devices. To patch an effects unit, connect the Preamp Output to the Input of the device. Next, connect the output of the device to the Power Amp Input (high-quality shielded cables must be used for these connections). The Preamp Output can also be used to route the amplified signal to a mixing console, tape recorder, etc. Connect the Preamp Output, using a shielded cable, to an input of the tape recorder, mixer, etc. This patch does not affect the operation of the amplifier. NOTE: The preamp output level is approximately 1 volt RMS and is of relatively low impedance (600 ohms). Any effects device used in this effects loop must be capable of receiving 1 volt input and providing 1 volt output in order to properly drive the power amp. The Power Amp Input has an internal switch which disconnects the internal preamp. DDT,M COMPRESSION (17) The amplifier is equipped with the patented DDT,M compression circuit (U.S. Patent 4,318,053). The compression circuit eliminates audible power amp clipping, reduces distortion, and protects the loudspeaker. In use, the Compressor LED may occasionally illuminate, indicating that the compressor is engaging to prevent distortion. If the LED is continuously illuminated, Gain control or Low EQ control settings should be reduced to prevent possible loudspeaker damage. POWER LED (18) Illuminates when AC power is being supplied to the amp. POWER SWITCH (19) Depress the switch to the “On” position. The red pilot light (LED) will illuminate indicating power is being supplied to the unit. BACK PANEL LINE (MAINS) CORD RETAINERS (20) Allow storage of mains cable for travel. LINE CORD (120V products only) (21) For your safety, we have incorporated a 3-wire line (mains) cable with proper grounding facilities. It is not advisable to remove the grou...
