ATSAH 500 MONO
The power amplifier is a Class D design and is based on NCore® technology from Hypex.
NCore® is the name given to the first significant step up in power amplifier performance in a decade.
Building on the strong heritage of the UcD design of Class D amplifiers, NCore® takes the things UcD
does well and does them ten times better.
Coupled with a dedicated switch mode power supply made specifically to work with the Class D design,
this amplifier not only nudges at the performance of the best linear amplifiers, but surpasses them in
every aspect of sound quality.
Efficiency is over 90% and with the ability to drive loads down to 2 ohms, these amplifiers are suitable
for the vast majority of loudspeakers.
The input to the amplifier is a fully balanced differential input and the connector is a
Neutrik® XLR female socket.
Speaker connections are via shielded binding posts which are able to accept banana plugs,
spade connectors or bare wire.

* At higher audio frequencies there are not enough harmonics left in the audio band to make
a meaningful THD measurement.
High frequency distortion is therefore determined using a 18.5kHz + 19.5kHz 1:1 two-tone
