2.0 INTRODUCTION The EQF 500 is a reissue that is our modern take on the classic Aphex EQF-2 500 series equalizer. The original EQF-1 500 module was designed in 1976 while the EQF-2 500 was an upgrade that included shelving EQ for the high and low bands. The newly designed EQF 500 module has an improved control layout and modern components have been incorporated for lower noise than the original.
3.4 EQ & FILTERS ON/OFF BUTTONS These lighted On/Off buttons allow you to turn the EQ and filters on and off individually. The buttons glow green when processing is on. They are dark when processing is off. Turning the button on and off offers a quick A/B comparison, allowing you to hear the affect the EQ and filters have on the program content. Note: These are hardwire bypasses. 3.5 LOW & HIGH PASS FILTERS The High Pass Filter range is from 20Hz to 500Hz. The Low Pass Filter range is from 1kHz to 20kHz.
4.2 SERVICE INFORMATION If it becomes necessary to return this unit for repair, you must first contact Aphex for a Return Authorization (RMA number), which will need to be included with your shipment for proper identification.
