WARNING TO PREVENT ELECTRICAL SHOCK OR FIRE HAZARD DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE BEFORE USING THIS APPLIANCE READ BACK COVER FOR FURTHER WARNINGS TM PERATING GUDE INTRODUCTION AND GENERAL DESCRIPTION Congratulations on your purchase of the TKO 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 asa 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 THE FRONT PANEL ON OFF SWITCH the on oif switch is a rocker type switch and should present no problems in operation In the on position a red LED will iluminate showing that power is being supplied
3. punch creates approximately a 6 dB boost of 120Hz and adds dramatically and effectively to the low end response and projection charactoristics of the TKO 65 PRE GAIN CONTROL The pre gain control is the first volume control of the system As mentioned in the post gain control description if the post gain control is set between its 8 and 10 positions for maximum power reserve the pre gain control should be positioned somewhere in the middle of its range or lower Placing tho pra gain control higher than 5 may cause unwanted square waves distortion and result in premature clipping and or undue activation of the DDT compression circuitry The pre gain Control also employs a pull bright switch which adds approximately 8 d8 of boost tothe high ena Like the high and presence controls the pull bright switch can be used to enhance many modern bass playing techniques INPUTS The TKO 65 has two inputs labeled high gain and low gain The high gain input is the inputwhicn should normally be used and will deliver the highest signal level from the instrument to the preamp to the power amp Sometimes however bass guitars that are equipped with very high output hot pickups will overload the high gain input This will be apparent because you will hear some unwanted cistortian at the loudspeaker If this distorted sound does occur plug the instrument into the low gain input which has less gain 8 dB then the high gain input When two in

5. EVENT SPEAKER DAMAGE AND OR FAILURE WE WOULD RECOMMEND THAT THE GAIN AND EQUALIZATION CONTROLS 8E READJUSTED UNTIL THE DDT LED WILL ILLUMINATE PERIODICALLY PATCH SECTION The patch section consists of two jacks labeled preamp out and poweramp 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 suchas flangers chorus tape anelog 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 nave amp greater degree of control over the sound quality of the device or signal processing unit The preamp output canalso 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 68 s preamp output tothe desired
6. channel of tha 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 instruments 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 contrals presence high mid shift and low are a unique combination of active and passive circuits to enable you to achieve a multitude of tonal colors By design with the exception of the presence control the tonal capabilities of the low mid and high controls will slightly interact with each other PRESENCE CONTROL The presence control should be used to adjust the extreme high end treble of the bass guitar or Keyboard signal This is an active control and as such will cause no effect on the other controls when placed at its 12 o clock or zero position For less Nigh end response rotate the presence control counterclockwise zero to 12 dB until achieving the desired high end roll off To boost the high end response of the preamp rotate the control clockwise zero to 12 dB The boost portions of this control are extremely effective for enhancing neck slapping string popping techniques see tone setting charts for further examples HIGH CONTROL The high control is conventional and should present no problem in
7. operation Clockwise rotation will increase the systems trable response while counterclockwise rotation will reduce the high end In conjunction with the presence control the high control will lurther enhance many contemporary bass playing techniques see the tone setting charts for further examples MID AND SHIFT CONTROLS The mid and shiftcontrols will enable you to have complete control over tne vital mid band frequencies The mid control is a equalization circuit allowing superb tailoring of the mid band and the shift control allows the bassist and keyboardist to determineat what lrequency the mid control will operate To get you acquainted with these two very flexible controls do the following experiment uf 4 Plug the instrument into the high or low gain jack Be 2 Adjust the pre gain control to 2 or 3 making sure that the pull bright switch is off ty 3 Adjust the post gain control above its 12 o clock or 5 position making sure thet Ihe pull punch switch is in its off position not pulled out 4 Place the mid control somewhere between 2 and 5 Piey your open first G atring or strike a note in the middle of the keyboard range and allow it to sustain 6 As the note sustains manually sweep the shitt contro from its 150 position to Its 1 5K position As the shift control is swept notice the dramatic changes occurring in the tonality of the mid band Through experimentation you will be ableto determine what settings are app
8. ropriate for your musical styles A good rule of thumb for the operation of tne mid and shift controls is For a well defined tignt sound country jazz more mid cut and lower operation of the shift control is desireable whereas for rock more mid boost end higher operation of the shift control is needed LOW CONTROL The low control is a conventional EQ circuit designed to provide smooth gradual increases in bass response over its entire range Although Ihe low control should present noproblem in operation it should be noted that overboosting of the low control may cause the TKO 65 s DDT compression LED to activate prematurely even at low volume levels Usually this occurrence can be corrected by cutting reducing the low control until the DOT LED activates periodically GAIN SECTION POST GAIN CONTROL In normal use the post gain control should be operated above the 12 o clock or 5 position To obtain maximum power reserve rotate the control fully clockwise to 10 NOTE WITH THE POST GAIN CONTROL AT 10 THE PRE GAIN CONTROL SHOULD NORMALLY BE OPERATED AT ORBELOWITS 12 O CLOCK OR 5 POSITION TO AVOID UNWANTED DISTORTION WHILE UTILIZING THIS MAXIMUM POWER SETTING AND EXTREME HIGH END BOOST IN THE EQUALIZATION SECTION YOU MAY FIND IT NECESSARY TO BACK DOWN CUT THE POST GAIN CONTROL TO APPROXIMATELY ITS 8 POSITION TO AVOID UNWANTED HISS The post gain control utilizes an integral pull switch call punch When activated
