OptimaLoop
‘Negative feedback’ is used in amplifier circuits to compare the
output signal with the input signal and correct errors, in order to
control gain and reduce distortion.
For sound quality, this is positive but a one-size-fits-all approach
to ‘global negative feedback’ can highlight different problems
whilst solving others – corruption of the error signal, phase shifts,
group delay. These have a negative impact on sound quality.
Different parts of a circuit benefit from specifically optimised
feedback loops, so we have developed a negative feedback
system that is much more accurate than the usual approach.
This incorporates multiple feedback paths instead of one global
loop, each path optimised for a particular function and working
synergistically with the others to deliver optimal overall
performance. We call this new configuration OptimaLoop.
