The MP573 is a two stages, single ended class A preamp, based on the design that was originally used in the Neve 1290/1073 modules, that has been adapted to the '500' format of API.
Just install it in your API* compatible LunchboxTM rack and start recording.
The sound of the MP573, like its model is full, silky, detailed and musical, slightly larger than life, very complimentary to a digital recording environment.
The MP573 is great on vocals, acoustic instruments and generally all close miked sources that need to be pushed forward in the mix.
1 Output level: Potentiometer that sets the signal level to the output stage
2 Signal/Clip LED: Flashes green when a signal is present and turns red 3 dB before clipping
3 Gain switch: In combination with the level potentiometer the overall gain can be set between 0 and +70dB. The 10 and 20 positions entirely bypass the input stage.
4 Input impedance: Center is the standard 1200 Ohms input impedance. Left sets a 300 Ohms low impedance, useful for ribbon mics that also adds 6 dB of gain. Right sets a 10 kOhm impedance input pad for line levels.
5 Polarity Sets the polarity (phase) of the output signal
6 Sends phantom power to the microphone
7 High impedance input (> 1 megohm) for instruments. The instrument signal goes through both transformers.
You bring the solder (use good quality solder, 1mm diameter max) and the Lunchbox.
The MP573 kit is an easy build in spite of a rather large number of components.
The only setup is adjusting the bias current in the output stage. It requires a standard DC voltmeter.
The XT500 option is a cable extension that allows you to test and setup the module outside the lunchbox while connected.

The 501 case option is a standalone, single slot lunchbox with PSU.The XT500 Extender is not needed with the 501.

If you prefer not to DIY, choose an Assembled product.Assembled products are built on demand and therefore require an additional delay of 2 weeks approximately.It comes fully assembled, ready to use.
