APEX

APEX(Audio Products of Excellence)사는 품질을 우선으로하는 이름 그 자체에 의미를 담고 있습니다. APEX사는 1990년 이후 프로오디오 시장을 시작으로 PE-133 싱글 디바이스에 그래픽EQ와 멀티 파라미터/놋치 필터를 내장한 제품을 시작, 파라그래픽EQ 역시 시장에 첫선을 보였습니다. APEX의 목표는 항상 음향의 고품질을 위한 혁신적인 디자인의 아날로그 및 디지털 제품개발에 있습니다. 풍부한 경험자와 젊은 엔지니어로 구성된 팀웍을 바탕으로 현 프로오디오 시장에서 오늘도 새로운 제품개발을 위해 노력하고 있습니다.

PE-232 MKII
  • the first ever and still unsurpassed EQ combining full-parametric and graphic equaliser in one device
  • constant-Q design for a real graphic representation by minimising adjacent band interaction
  • DLT-technology for ultra accurate and artefact-less frequency, phase and amplitude response
  • the perfect choice for monitor mix and poor acoustic venues

The heart of all PE- equalisers graphic section is a bank of 30 constant-Q bandpass filter made with Dynamically Laser Trimmed (DLT) hybrid circuits. The DLT-technology offers you ultra accuracy and artefact-less frequency, phase and amplitude response, the constant-Q design preserves filter bandwidth independent from the amplitude control settings and therefore minimises the adjacent band interaction. Constant-Q reinforces the graphical representation by the front panel faders of the actual frequency response.

Beside the graphic section, the PE-series features factory calibrated full parametric filters with unprecedented fine frequency tuning "vernier control", giving you the ultimate opportunity to fine-tune and remove unwanted sound wave as hum or potential feedback frequencies without disturbing the original overall frequency response. Typically, this enables an increase in system gain of 15 dB before feedback occurs.

The PE-232MKII equaliser has also a frequency adjustable high-pass filter per channel plus in/out switches for instant comparison with flat response on each equaliser section.

All potential overload points are continuously monitored by an extremely fast attack, slow release time peak detector circuit illuminating a LED indicator 2 dB before the clipping point is reached, warning the user to reduce the level before distortion occurs.

In case of mains power failure, relays will automatically bypass the equaliser by connecting each input to his output instantaneously.
