   Applications

Monitor loudspeakers for recording
   and mastering studios
Audiophile power amplifiers for
   professional and consumer use
Public Address systems
Home theatre systems
Active loudspeakers

Also available with pre-mounted HxR
   regulators.

 

Technology
The UcD™ circuit is based on phase-shift controlled self-oscillation, with only a single voltage feedback control loop taking off at the loudspeaker terminals. The control function is constructed fully out of passive components, with only the comparator standing in for gain.
