TEQSAS TQX


Loudspeaker tester, cable tester, line check


The TEQSAS TQX is a universal test device for sound engineers and event companies. Loudspeakers, audio cables and line signals can be tested. The TQX has an internal battery, an internal memory of 2GB and an internal 10 Watt power amplifier.

  • Loudspeaker test via CA-Com/NL8 or SpeakON NL4
  • Line signal monitoring via headphones or internal loudspeaker
  • Audio Player
  • Cable tester for NL4, CA-Com or NL8
  • Output power: Max. 10W at 6 Ohms
  • Transformer-metered LINE IN / OUT
  • 24 Bit / 44,1 KHz/ 48 KHz WAV / Mp3
  • 2 GB flash memory

The TQX was launched in 2019 to make life easier for technicians and companies in the sound and event technology sector. The TQX is a test instrument that has been developed from practical experience to simplify challenges in the everyday life of every technician.

As a system and event technician, you know these problems:

  1. The line arrays could be moved to the final position in the roof of the venue, but there is no power to the amplifiers yet to test the line arrays.
  2. There is always a power amplifier in the warehouse to test speakers from a production before they can be re-storaged. Of course, this power amplifier isn´t available for rental.
  3. When doing a line check on stage, you can use phantom power to test whether the lines of the multicore are connected, but you can't detect a hum, for example. not recognise.
  4. At the workshop in the warehouse there are cables with a sticker "defective", but it cannot be determined where exactly the fault lies.


These are all problems and challenges from everyday life that the TQX takes on.

Is the TEQSAS TQX only available in one version and do all versions have a battery installed?

The TQX is available in two different versions.

There is a CA-COM version. The multipin connector is a CA-COM socket. The measuring adapters in the set are also designed for CA-COM accordingly.

and

There is also an NL8 version. The multipin connection is accordingly an NL8 socket. The measuring adapters in the set are also designed for NL8 accordingly.

Both versions have a built-in rechargeable battery that can be charged via the supplied USB power supply. The battery lasts about 2 hours in continuous operation under load.
What are the functions of the TEQSAS TQX?

As mentioned at the beginning, the TQX can solve or simplify a wide range of problems and challenges. In the following, we would therefore like to break down the functions of the TQX in more detail.
Power amplifier
The most obvious feature is certainly the internal 10 watt power amplifier. The TQX has the option of operating one channel of the NL4 or the Multpin connection via the power amplifier. The power amplifier can be loaded with up to 2.7 ohms.

Accordingly, the different pairs of loudspeakers within an array, for example, can be played back one after the other. (As in the picture)

As a safety feature, the TQX has a switchable high-pass filter to protect the tweeter in 2-way active speaker systems.

The TQX's internal power amplifier receives the input signal either from the internal .mp3/.wav file player or the XLR line input. This way, the loudspeakers can be played with a measurement signal or music track of your choice.
Cable tester
The cable test function makes it possible to find the following faults in a cable:

  • Polarity is reversed
  • Short-circuits
  • Cable has no passage
  • Whole pairs of wires are interchanged

These errors are displayed in a matrix on the 1.8" TFT colour display with green and red dots. It is therefore easy to read and errors can be classified immediately.

To use the function, one side of the cable must be plugged into the TQX and the other side onto the measuring adapters supplied. The picture shows the CA-COM test adapter.
Line-Check:
The TQX has an XLR line input and output, a headphone output and an internal speaker. The TQX has the option of outputting the signals from the internal memory to the XLR line output.

Furthermore, it is possible to output and listen to the signals present at the XLR line input on the internal loudspeaker or the headphone output.

As already described above, the signal at the XLR input can also be optionally routed to the power amplifier
DI function:
The TQX has the ability to act as an "emergency" line isolator when switched off.

When the TQX is switched off, XLR line input and output are connected via a transformer over the built-in potentiometer.
