Official description
The MPD500 is a full-featured discrete microphone preamp with DI from the manufacturer of the famed VAC-Rac stereo tube limiter. Using the all-discrete SPA-690 Op-Amp, this design gives a very high-bandwidth and musical tone without a trace of sterility. Features include balanced input and output transformers, output level rotary control and 3 hi-pass filter selectable switches at 70Hz, 100Hz and 200Hz. The MPD500 has a +48VDC phantom power switch, phase reverse switch and –20dB pad switch and 12-position rotary trim adjustable at 5dB per step within the 25dB to 80dB selectable range. Also featuring a Hi-Z low level line input 1/4” phone jack for guitars, keyboards and low level instruments, the MPD500 fits standard 500 series’ slot configurations both mechanically and electronically.
