All critical circuitry utilizes four layer glass epoxy circuit boards. With its 100 VA
power supply and 11 independent stages of regulation, the power supply of the
KRELL PLAYBACK SYSTEM-20 is a rock solid source of pure current and
voltage for the digital and Class A analog output stages. The output stage is
classic KRELL. All output circuits are DC coupled, Class A and complementary.
The output stage has 18 volt rails and fully differential balanced outputs on gold
plated, berrylium copper XLR connectors. Single-ended outputs are also
provided via custom gold plated RCA connectors.
In the KRELL PLAYBACK SYSTEM-20i/I the high level output stage of the
KPS-20i is replaced with a line level output stage and volume control simfliar to
that of the KRELL KRC-2 preamplifier. This stage is optimized to drive the input
of a power amplifier directly.
The KPS-20i and KPS-20i/I support all major digital input formats: one ST fiber
optic, one AES/EBU balanced, two SPDIF coaxial, and one EIAJ optical. They
come standard with an SPDIF coaxial digital output. ST, EIAJ, and KRELL Time
Sync outputs are available as an option. All input switching is accessible from the
front panel or the remote control. KRELL’s proprietary Data Recovery and Jitter
Rejection Module recovers all data from external sources, reducing jitter to
exceptionally low levels.
