MP599 Microphone preamplifier

MP599 Microphone preamplifier for the '500' Lunchbox - Kit

The MP 5.99 is based on one SK99 discrete Op-Amp, one Lundahl input transformer and one Lundahl output transformer.

Because of the high performance, mu-metal core Lundahl transformers, the MP 5.99 features the warmth of the iron but it is also an extremely transparent mic pre that will capture all sound sources with extreme finesse.

The MP 5.99 is great on all transient rich sources like acoustic and percussive instruments. It will shine in close or distant miking applications.

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