Typical Configuration

Typical Configuration - System 5000

Typical configurations utilize either a parametric or graphic EQ at the audio entry point to permit user coloration of the sound.* This is then fed to the Muse audio processor where we perform the System 5000 computations for hearing enhancement.

In order to conserve DSP headroom, in cases of strong correction requirements, we de-emphasize high frequencies and then use another Massenburg 8200 to re-emphasize them in the analog domain.

Finally the processed sound is sent to a Grace Design reference amplifier and then to Sennheiser HD650 headphones. The Grace Design amplifier also provides Line Out signals for feeding speaker amplifiers if desired.

This particular system would be delivered in a 7U mini 19" rack, with all cabling and power supplies installed and neatly routed in the back. We work with you to provide attactive cabinetry for this rack. The only connections needed to your equipment are balanced XLR cables to your mixing console for the left and right channel +4 dBu audio signals, and a single A/C power cord. We provide the cabling for those too.

*(EQ coloration of sound can only be properly applied ahead of hearing corrections. With imperfect hearing, the nonlinear recruitment causes direct EQ to be heard correctly at only one specific loudness level. As sounds grow louder they will be perceived as too loud. As sounds grow softer they will be perceived as too soft. By placing the coloration EQ ahead of the hearing enhancements, it will be percieved correctly by the listener.

Also, with all due respect to George Massenburg, who claims quite properly that his EQ's are the most transparent and non-coloring available, we intend the meaning of "coloration" to be slightly different than his. We view any alteration of the sonic spectrum as "coloring the palette". Massenburg EQ's are simply among the very best at not producing unwanted colorations, to use our vernacular.)
