ABOUT YOUR MPA
The NAGRA MPA amplification system consists of a stereo block amplifier of the finest quality
which is designed for vertically or horizontally position.
The MPA is designed and hand-built entirely in Switzerland by NAGRA engineers, using
components of the highest possible quality from around the world.
•
Fully symmetrical (balanced) design allowing better distortion, good hum immunity,
intermodulation and short rise time characteristics.
•
A special PFC technique (Power Factor Corrector) is used to deliver the power to the
output stages. Thanks to the PFC, the AC current consumption becomes a sine wave
and not a spike wave. The audible harmonics in the AC current drain are very low. This
improves the facility to use other sensitive equipment nearby the MPA.
•
Built-in Meter to indicate loudspeaker loading (only with RCMI option).
•
Two pairs of loudspeaker terminals for all kind of loads.
•
The MPA enclosure is CNC machined from hardened aluminium and is designed to
provide many years of durable service.
•
The MPA complies with all existing electrical safety and electromagnetic emission
standards.
