MP512 Microphone preamplifier

MP512 Microphone preamplifier for the '500' Lunchbox - Kit

The MP 5.12 is based on one discrete Op-Amp, one Cinemag input transformer and one Cinemag output transformer.

It delivers what is called the "LA" sound, popularised by the famous American consoles of the 70's : the punchy midrange and tight bass tone of the iron. This MP 5.12 is great on drums, electric instruments and generally all close miked sources.

Just install it in your API* compatible LunchboxTM rack and start recording.
