BEFORE USING THIS APPLIANCE, READ BACK COVER FOR FURTHER WARNINGS. 1KO 65 OPERATING GUIDE INTRODUCTION AND GENERAL DESCRIPTION Congratulations on your purchase of theTKO™ 65 bass amplification system. After reading this owner's manual you should have an understanding of the operating principles of the TKO'“ 65. A thorough understanding of these instructions will also help you to achieve many varied tonal settings. The TKO™ 65 is an advanced, medium powered single unit bass amp designed primarily for studio and club applications and is equally effective as a medium powered keyboard amplification system. The TKO’“ 65 utilizes flexible input circuitry and gain (volume) controls as well as a unique system of active/passive equalization. Both the bassist and keyboardist will benefit from the unique and highly versatile circuitry employed in the TKO’“ 65. As with any sophisticated piece of equipment, there are some operating principles concerning the inputs, gain controls, equalization and patching facilities which must be understood to obtain the best tonal results. Please read this owner’s manual and keep it handy for reference. ?0 2 ♦ •0 Xffit 111 CIl- PS Q-<0 m 31 + iu cu o “ 8\ (0 0) I CL LL I I-in r ml § Vl 01 3 nJLo> L ID#’ v *- if] I J (£d n w THE FRONT PANEL ■ON/OFF SWITCH: the on/off switch is a rocker-type switch and should present no problems in operation. In the on position, a red LED will illuminate showing that power is being supplied to the unit. NOTE: WHEN THE UNIT IS TURNED ON, THE COMPRESSION LED INDICATOR (DDT) WILL MOMENTARILY ILLUMINATE ■ GROUND SWITCH: The ground switch is a 3-position rocker-type switch which, in most applications, should be operated in its center or "zero" position. You may encounter some situations where an audible hum and/or noise will come from the loudspeaker. If this situation arises, position the ground switch to either positive or negative until the noise is minimized.NOTE: SHOULD THE NOISE PROBLEM CONTINUE. CONSULT YOUR AUTHORIZED PEAVEY DEALER. PEAVEY FACTORY OR QUALIFIED SERVICE TECHNICIAN. DO NOT UNDER ANY CIRCUMSTANCES. REMOVE THE GROUND PIN ON THE MAIN (POWER) CABLE DDT™ COMPRESSION LED: The TKO™ 65 utilizes our patented DDT™ (Distortion Detection Technique) compression circuit to effectively minimize the possibility of distortion (square waves) from entering the loudspeaker. (U.S. Patent #4.318,053). As mentioned in the on/off switch section, the DDT’" 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 that the DDT'“ circuit is automatically engaging to prevent distortion. NOTE: IF THE DDT™ LED REMAINS CONTINUOUSLY LIT WHILE YOU ARE PLAYING. THIS IS AN INDICATION THAT THE GAIN (VOLUME) CONTROLS AND/OR EQUALIZATION CONTROLS ARE SET AT POSITIONS THAT IS MAKING THE POWER AMP OVERWORK ALTHOUGH THE DDT™, IN MOST CASES. WILL PREVENT SPEAKER DAMAGE AND/OR FAILURE WE WOULD RECOMMEND. THAT THE GAIN AND EQUALIZATION CONTROLS BE READJUSTED UNTIL THE DDT LED WILL ILLUMINATE PERIODICALLY. PATCH SECTION: The patch section consists of two jacks labeled preamp out and power amp in. Primarily the preamp output and power amp input jacks are used for patching effects devices and signal processing equipment "in-line" with the TKO™ 65 Most of devices such as flangers. chorus, tape/analog/digital delays or gain devices such as external compressors can be used within this effects loop. The preamp output level is approximately 1 volt RMS and is of relatively low impedance - 1000 ohms To utilize the 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 TKO™ 65. 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 after the 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. For this method use a high quality, shielded patch cord and make the connection from the TKO™ 65's preamp output to the desired channel of the mixer or to an auxiliary device where the signal is not to be returned to the power amp input of the TKO™ 65. With this method of sending your instrument's signal to a mixer or auxiliary device, you do not have to utilize the power amp input as the signal will automatically feed the power amp section. (For further uses of the preamp output/power amp input see bi-amping the TKO™). EQUALIZATION SECTION The equalization controls (presence, high. mid. shift and low) are a unique combination of active and passive circuits to enable you to achie...
