- Full channel strip in a 500 Series module
- Class A mic preamp
- Optical compressor
- Dual-band semi-parametric EQ
The optical compressor uses a proprietary optical element designed to be as fast as possible. A ratio knob is provided to control the amount of gain reduction, which can be adjusted from 2:1 up to 6:1. The compressor can also be turned on/off with the lighted Comp button. A gain reduction LED labeled GR will glow yellow when gain reduction is taking place – the more gain reduction, the brighter the LED will glow. The compressor can be placed before or after the EQ with the lighted Post button at the bottom left of the module.
Aphex's Project 500 has two bands of semi-parametric EQ. The Lo Freq can be adjusted between 20Hz and 2kHz, while the Hi Freq can be adjusted between 200Hz and 20kHz. Both bands can be boosted or cut by up to 15dB. Both bands have a non-adjustable, medium bandwidth.A ¼”, 10Mohm instrument input is provided on the front panel, allowing the Project 500 to be used with guitars, basses and other high impedance instruments. This input overrides the module’s receiving frame XLR input, allowing the user to keep XLR cables inserted. Finally, the Output knob controls the overall output level of the module.
