- Page 3 Congratulations on purchasing one of the world’s finest professional instrument combo amplifiers! The TCA-500 combo amplifier is a state of the art audiophile quality unit designed and built with the latest and best sounding technologies. It has been carefully engineered to provide every function and convenience possible within its cost/benefit ratio, for the professional musician.

- Page 5 It accepts a special twist lock plug for a secure connection of power to the pedal. A power lead with locking connectors is supplied with the TCA-500 Amplifier. High impedance (1Meg Ohm) instrument input - will not load down your guitar Input pickup or adversely affect your tone.
- Page 6 The problem with this is the Input Gain control affects the level sent to the effects unit. Always use the Master Level to control output volume after the Input Gain control has been adjusted as outlined above. Telonics TCA-500 Combo Amp PB-009289 Rev _ PRELIMINARY...
- Page 7 If you were to set the Mid Level control to Zero dB (3 o’clock knob position), the Mid Frequency control would ‘do nothing whatsoever” to your sound, it would have NO effect on your tone. Telonics TCA-500 Combo Amp PB-009289 Rev _ PRELIMINARY...
- Page 8 Sets the frequency at which the Mid Level control has an effect. Several Mid Frequency frequency intervals between 375 Hz and 1400 Hz are marked. Its effect is determined by the setting of the Mid Level control. Proper adjustment is achieved Telonics TCA-500 Combo Amp PB-009289 Rev _ PRELIMINARY...
- Page 9 Normally, players leave this control at zero and only adjust it slightly between +1 or -1 to compensate for the venue (room size, crowd size, bandstand configuration (even for relative humidity changes, as sound propagates differently with humidity changes).

- Page 11 DRY/WET Fader is set fully Dry no reverb will be heard. If the TCA-500 is used with a 19” rack effects processor, (such as a Lexicon MX-200, a T.C. Electronics G-Major/II, or other 1U space multi- effects unit), we would recommend the built-in reverb be turned off and patches set up on the effects processor;...
- Page 12 Level on the rear panel. This is adjustable to drive effect inputs from, - 30dB to +4dB ; the +4dB setting generates the highest output. It’s very important to ensure the TCA-500 Overload LED just starts to blink BEFORE the effects processor input level reaches its maximum input level or clipping point.
- Page 13 For this reason we would therefore not recommend using effects processors in a series mode that introduce latency. Telonics TCA-500 Combo Amp PB-009289 Rev _ PRELIMINARY...
- Page 14 / headroom practice must be considered when developing patches. In parallel mode the dry or thru signal is passed within the TCA-500 and only the effected signal is returned by the effects processor. When developing patches for parallel mode use, it is essential that the effects processor is not allowed to pass an unaffected or straight through signal.
- Page 15 The DO in the TCA-500 is analog modeled to deliver to a flat response system, a very closely EQ’d approximation to what is output from the combo speaker in its cabinet.
- Page 16 EFX units following his instrument to the Aux input on the rear panel of the TCA-500, thus providing for quick switching to a Tele, MandoCaster, mandolin, or other instrument.

- Page 18 The Mute circuitry is designed to be super quiet when switched On and Off. When the Mute is On the Yellow Mute LED is lit. The Mute system in the TCA-500 is very handy for string replacement, practice licks, tuning, and effects adjustment during live venue situations.

- Page 20 AC mains cord plug. Always check to be certain that your effects processor voltage suits the supply voltage applied to the TCA-500 Combo Amplifier. Note; the power taken by the effects processor should not exceed 50 Watts.
- Page 21 This potentiometer allows you to select the nominal signal level EFX Return Level coming from your effects unit, it is adjustable from +4dB to less than -30dB. Most “Pro” equipment is usually +4dB while consumer equipment is usually -10dB. Telonics TCA-500 Combo Amp PB-009289 Rev _ PRELIMINARY...
- Page 22 The Preamp Out jack is a line level output from the preamplifier section Preamp Out of the TCA-500 that can be used to send the fully processed signal to another power amplifier, powered speaker, etc. Using a standard guitar cable with 1/4 inch TS plugs on both ends, this jack can be used to treat this TCA-500 as a “Master”...
- Page 23 The Power Amplifier Input accepts line level signals from another source Power Amp Input to the power amplifier and local speaker in the TCA-500 Combo Amplifier. When used, this jack will disconnect the internal preamplifier signal from going to the Power Amp. Only the external signal coming in on the TS plug will be amplified through the speaker.
- Page 24 This level should be suitable for most pedal based effects and professional 19” rack equipment that operates around 0db. Return from volume pedal or an effects unit or chain and is also prior to the Pedal From equalization. Telonics TCA-500 Combo Amp PB-009289 Rev _ PRELIMINARY...
- Page 25 CAUTION Both wires have an AC voltage on them. DO NOT allow them to short to ground when you should hear sound, as this could cause a failure. NEVER use grounded equipment to measure the speaker output. Telonics TCA-500 Combo Amp PB-009289 Rev _ PRELIMINARY...
- Page 26 YSTEM NTRODUCTION The cooling system for the TCA-500 Audio Amplifier consists of two variable-speed fans and an intelligent digital controller circuit. The speed of the fans is determined by the temperature at multiple key points within the amplifier. The controller is designed to run the fans at the slowest possible speed sufficient to maintain the amplifier at a safe operating temperature, and thus yield the quietest possible operation.

This circuit will not load down other circuitry in the TCA-500. The front and rear panel jacks can be used at the same time. The Tuner Out can also be used as an effects Send. - Page 29 Normally, you would be stuck. By using this control, you can simply reach over, set your house volume through the PA board, and hopefully, not start a “sound war” when he returns to the booth…..

- Page 30 The Reverb On/Off switch is positioned on the lower right corner of the front panel. A ¼ inch TRS cable is required to connect the TCA-500 side of the Control Unit to the “Foot Switch” jack on the rear panel of the TCA-500. This cable is identified by a white right around the cable directly behind the TRS plugs on both ends.
- Page 31 The button at the upper left of the front panel controls Effect Engine #1 (normally programmed for Delay effects in Telonics patches), and the button at the lower left of the front panel controls Effect Engine #2 (normally programmed for Reverb effects in Telonics patches). The buttons are labeled accordingly.
- Page 32 Once set to your satisfaction, the BLEND control can be rocked slowly while striking a wide grip of strings repeatedly to accurately “fine tune” all the EQ settings at one time. Remember that these controls are sensitive, so a little adjustment can change a lot. Telonics TCA-500 Combo Amp PB-009289 Rev _ PRELIMINARY...
