About the APEX GX 130
The APEX GX 130 is a 30-band 1/3 octave graphic equaliser built to professional standards in electronics and mechanics. Its core is a bank of 30 constant-Q bandpass filters, each individually laser-trimmed at the factory using APEX's Dynamic Laser Trimming (DLT) hybrid circuit technology for accurate frequency response. A sweepable highpass filter with a 12 dB/oct slope and a sweepable lowpass filter with selectable 6 or 12 dB/oct slope precede the equaliser section. Additional features include switchable 6/12 dB scale on the graphic equalisers, 6 dB of available gain, true differential input circuitry, effective HF interference cancellation, XLR inputs and outputs, accurate peak-stretching overload indicators, an earth-lift switch, and a failsafe bypass. The power transformer uses low-flux windings and magnetic screening to reduce stray magnetic fields.

Who makes the APEX GX 130 and where does it fit in their range?
The APEX GX 130 is made by APEX Audio, a Belgian pro audio manufacturer that designs and builds its products in Belgium. The company is now part of the Community Europe group under Giva Audiovisual Technologies and covers signal processing alongside installation amplification. The GX 130 represents APEX's approach to precision graphic equalisation, using their proprietary DLT hybrid circuit technology to achieve accurate filter response.
What are the key filter and connectivity features of the GX 130?
The GX 130 provides a sweepable highpass filter with a 12 dB/oct slope and a sweepable lowpass filter with selectable 6 or 12 dB/oct slope. The graphic equaliser section offers a switchable 6/12 dB scale and 6 dB of available gain. XLR inputs and outputs are fitted, with true differential input circuitry and effective HF interference cancellation. An earth-lift switch and accurate peak-stretching overload indicators are also included.
What should I check when buying a second-hand APEX GX 130?
Check that all 30 fader bands move freely and return accurate response, that the sweepable highpass and lowpass filters engage correctly, and that both XLR connectors are undamaged. Confirm the earth-lift switch and failsafe bypass function as expected, and inspect the front panel for physical wear. Used units on 10K Used carry a 21-day warranty covering major functional faults; full details are in the buying guide at 10kused.com/used-av-equipment-guide/.
