Installation & operating instruction

Mains power connection

• Before connecting the amplifier to the mains power socket, make certain that the voltage Corresponds with that indicated on the rear of the unit (AC220V $ 10% ).
• Before connecting the power cable to the mains, always make certain that it is not damaged and that there are no bare wires, always connect the power cable to the amplifier before Switching it on and only remove the cable after switching it off.

Switching on and off

In an audio system, it’s always better to switch power amplifiers on last and off first. Remember to switch off the amplifier before connecting it to or disconnecting it from other units and to switch always on first the mixer and then the amplifier: in this manner, peaks that are annoying and sometimes dangerous particularly for the loudspeakers enclosures are avoided. It is normal for the LEDs to light up for a few moments when switching on.

Handling

• Do not force knobs and connectors, as they could be damaged if treated with excessive force.

Connector cables

• To connect the amplifier to the mixer, always make certain to use only signal cables (screened cables made up of two wires plus a braid screen), not power cables (speaker cables, normally made up of two wires, usually with a greater cross-section) to connect the amplifier to the loudspeaker enclosures, always use power cables, not signal cables, as in the latter case in the act, the power from the amplifiers would be partially dispersed because of the cable’s smaller cross-section.
• Take care of the connector cables. Always hold them by the connectors, avoiding pulling the wire and avoiding knots and twists when coiling them: this gives the advantage of increasing their life and reliability.

Air circulation for cooling

• The amplifier’s correct cooling is ensured by internal fans, the speed of which is controlled by special sensors (the speed is proportional to output power, remember never to block the air vents in any way: the air necessary for cooling passes through these.
• If the amplifier is kept in a flight case during use, make certain. that it has sufficient openings at both the amplifier’s air vents. Avoid locating very small spaces that don’t allow correct air circulation.

Warming High Voltage

• Please attention fan-out high voltage, and polarity, not short circuits.
• When the product is working, don’t touch the output connector for safety.

Functions & controls

Front Panel of TKA Series

Rear Panel of TKA Series

1. PROTECT LEDS
2. • Protection pilot lights

  * If these LEDs light up, this indicates that one of the various protections safeguarding the different sections of the amplifier and the loudspeaker enclosures has tripped due to an operating fault.
  * In these cases, the power output is normally switched off until normal operating conditions are restored.
2. The following is a description of the series of protections
3.  **Switch on AC soft working Protection:** Limit the electric current when starting up, don’t affect the other pieces of equipment or out the rush of the circuit inside.
4.  **Delay the link load:** protect the loudspeaker, and keep silent when starts up.
5.  **Circuit damage protection:** midpoint excursion and output the AC, limit the damage to extend.
6.  **Limit the output current Soft protection:** The loading impedance is low and too drastic signal; it can protect the loudspeaker and amplifier.
7.  **Clip and compress protection:** When input too big signal, the clip output is distorted, and it is easy to damage the speaker unit; this circuit can check the compressed signal to protect the loudspeaker:
8.  **Short Circuit Protection:** trips in the event of a short circuit or overload, limiting the output current.
9.  **Over hot protection:** In high temperature and low overload state, the temperature grows hot quickly, and the protection will work to cut the load over 90°C. The amplifier will rework below 75°C.
10.  **Switch off Protection:** First, turn off the overload when switched off, it keeps the loudspeaker silent out of the rush.
11. Some protection situations require the amplifier to be switched off and then back on for normal operating conditions to be restored.

2. LIMIT LEDS
   • Amplifier” status” indicators: these LEDs can indicate for channels A and B, the operation Of the internal limiter when inserted, or the clipping of the amplifier:
   • These 2 LEDs are POST-LEVEL: in other words, they display the status of the signal when it has already been regulated by the input level controls.
3. SIGNAL LEDS
   • Signal “status” indicators: these LEDs can indicate for channels A and B, a signal Presence in the inputs of the amplifier.
4. LEVEL
   • Control of the input level of the external signal: operates with continual values which vary From “fully closed” (position “MIN” – the signal is not fed to the amplifier sections) to fully open” (position ” MAX” -the signal is sent to the amplifier sections at the same level as that with which it arrives at the input). in other words, this control operates as an attenuator of the signal fed to the amplifier.
5. AIR VENTS
   • Amplifier cooling system air in/out vents.
   • The fan of the cooling system creates a flow of air with front to back direction: this means that the Air is taken from the front panel to the back cover, and having cooled the heat sinks and transformer. through the opening on the backside.
   • Care must always be taken to avoid blocking these openings and to never place the amplifier in a position that does not allow sufficient air circulation.
6. POWER ON
   • ON/OFF switch with indication LED. (Active LED)
7. INPUTS
   • Each channel has an XLR input. and an XLR input for parallel output.
8. OUTPUTS
   • STEREO outputs: output of CHA: the 1+” is the “#” of CHA, the1 – is the – of CHA, the “2+” is the of CHB, and the ” 2-” is the – of CHB. the output of CHB: the 1+” is the of CHB, and the ” 1-” is the – of CHB.
   • Wiring method 1:
   • Wiring method 2:
9. STEREO/ PARALLEL selector
   • Selector for the amplifiers 2 operating setting: allows to decide how to use the amplifier in the audio setup and connect with other units (crossovers, other amplifiers, loudspeaker enclosures).
   • This control should only be used when the amplifier is off, otherwise the loudspeaker’s Components could be damaged.
   • A) STEREO
   • With the STEREO setting, 2 separate signals are treated separately by each channel of the amplifier.
   • B) PARALLEL MODE
   • With the parallel setting, when inputting one signal, the parallel channel can output the signal at the same time.
   • When switching 1&2 open, CH.A and CH. B are parallel.
10. GAIN adjust
    • According to different files, it can set different gains for each channel (32dB/35dB/38dB/41dB).
11. POWER INTERFACE
12. NOISE GATE
    • The factory default is – 80dB. Click to change to – 75dB, and click again to change back to -80dB. In this cycle.
    • Press and hold for 5 seconds to close the squelch door function, and then press and hold for another 5 seconds to open the squelch door function
