Because the REF500M runs cool, it can be placed in
many system locations without compromise. We do
not recommend placing weights or other objects
directly on the REF500M. This may scratch or mar
the chassis finish. Do not use harsh chemicals
when cleaning the outside of your REF500
M.
The e.One Series REF500
M is a mono audio amplifier designed to deliver over 250 watts into 8 ohm loads and
500 watts into 4 ohm loads. The REF500
M has current drive capability for virtually any loudspeaker load down to
3 ohms. This is achieved in a compact and elegant product through our adaptation of the latest analog switching
amplifier and power supply technology from the ICEpower group.
Bel Canto’s new generation of e.One analog switching audio power amplifiers extend our leadership in this
technology. These amplifiers incorporate performance enhancing technologies that bring musicality and
performance to new levels.
REF500
M Features:
• A custom input stage is added for increased linearity, common mode rejection and improved input stage drive
to the amplifier. This circuit results in lower noise in real-world operation, lower distortion and better dynamic
performance for the amplifier.
• This input stage uses the latest advanced amplifiers and passive components including: Caddock resistors,
Solid Electrolytic ultra-low ESR decoupling capacitors and low noise regulated power supplies. These devices
ensure that the input section is utterly transparent, enhancing the performance of the core amplifier.
• The REF1000
M and REF500M Mono amplifiers also include custom power supply rectification and filters that
add 45 Joules of energy storage to the power supply. This stage results in lower noise in operation, reduced
sensitivity to power line effects and better perceived power delivery and dynamics. Incorporating high speed,
low noise rectifiers, high voltage film filter capacitors and high energy storage, this filter allows the regulated
power supply to perform at its best.
• The REF500
M uses 3
rd
generation switching amplifiers for lower high frequency distortion, increased clarity,
and better high frequency extension.
The REF500
M’s sonic performance will start to stabilize after approximately forty (40) hours of continuous power
up. We recommend that the REF500
M remains powered for optimal performance.
