INGRAMENGINEERING MPA575 Audio Sample Page

 

Audio samples were recorded using the MPA575 with a wide range of instruments and microphones to demonstrate the quality that can be achieved. Steaming files as well as downloadable files are linked below. For additional audio samples, we refer you to the MPA685 audio samples page, as the MPA685 and MPA575 share the same design approaches and, in fact, share the same discrete audio amplifier design.

 

The first group of songs are by Jason Deutsch, recorded at Slack Key Studios by Randy Kohrs. The MPA575 was used for drums and percussion. Streamed files are saved as MP3 format, 44.1kHz sampling rate, 128kbps encoding; downloadable files are save as .wav format, 44.1kHz sampling rate.

Randy Kohrs hosted a listening session at his Slack Keys studios with the MPA575 and a variety of other gear.  The following group of comparisons resulted.  For these files, Joel Hamilton played acoustic guitar and tracks were recorded through the different pre-amps listed.  A Peluso P-28s mic was used for all tracks.  For the MPA575 tracks, high impedance mode was used, and EQ and Compressor were off during tracking in order that comparisons of just the pre-amp functions could be made.  Subtle differences in especially the upper frequency articulation is apparent when comparing the MPA575 (with EQ off) to the tube-based pre-amps or the Neve-based RTZ Audio 9762A.  To demonstrate the versatility of the MPA575, the file was reprocessed through the MPA575 with the see-saw EQ on and adjusted to -3 for slight high frequency de-emphasis, HPF was engaged with frequency = 120Hz and the compressor was engaged with threshold at -9dBu and sidechain EQ flat.  This file shows the ability of the MPA575 to take on a darker personality and more directly compare to a Neve-type sound.  Streamed files are saved as MP3 format, 48kHz sampling rate, 128kbps encoding; downloadable files are saved as .wav format, 96kHz sampling rate.
