GX-Series
Graphic equalisers are made of 15 or 30 band-pass filters, one for each 1/3 octave frequency. Conventional equaliser designs use standard discrete components to realise these band-pass filters. Apex GX- and PE- series achieved far better results by using hybrid circuits applying Dynamic Laser Trimming (DLT) technology.DLT requires each filter of the graphic equaliser to be laser trimmed to match the acoustic transfer to the optimum ideal response. The result is a optimally controlled amplitude and phase response.
Reference single 30-band constant-Q graphic equaliser
The heart of the Apex GX-130 equaliser is a bank of 30 constant-Q bandpass filter made with Dynamically Laser Trimmed (DLT) hybrid circuits.
The GX-130 equaliser has also frequency adjustable high-pass and low-pass filters.
