Works like the perfect board
operator smoothly riding gain
without any processing artifacts
(pumping, breathing, ducking,
hole punching).
Other processors sound dissected or synthetic by enhancing artifacts and
squashing out natural details. The MkII Multiband remains cohesive and
natural even with the heaviest processing. Its flexibility offers a full palette of
sonic textures.
The Model 2020 was hailed worldwide as the FM processor of choice for stations where sound quality and loudness are
equally important. Review after review talked about “clarity”, “naturalness”, “loudness”, “lack of annoying artifacts”, “great
value”, “deep, rich bottom end”, “clear unclouded midrange and highs” - the list of accolades went on and on
*** . Now
with new circuit designs, improved processing algorithms and new features the reviewers will have to find new superlatives
for the 2020MkII.
In addition to the superb audio quality, the 2020MkII is very functional and easy to use. Other features include:
• Password security system • Programmable and automatable for day-parting • Headphone Input/Output Monitor
• Remotely and locally controllable • RDS input/output and dual composite outputs
• Can also operate in a dual mono configuration - a cost and space-effective idea for single channel broadcasters
• Insert loop for adding additional processing such as the Aphex Aural Exciter and Big Bottom
• Digital I/O option includes our patented Drift Stabilized A to D Converters*
• Ultra-precision oven-controlled crystal oscillator option
Additional Features
Since 1975 Aphex Systems has designed and manufactured
innovative signal processing equipment for professional
applications. Many of our processors have become the de
facto standard of the industry in their particular categories -
(Dominator
® , Compellor ® , Aural Exciter ® , Big Bottom ® , etc.).
It is with this heritage that we undertook the development
of the original 2020. After five years in development and 15
new proprietary techniques, we created the finest sound-
ing FM processor available. Two years later and with three
new proprietary techniques the 2020MkII was born. Aphex
research ensures that each and every link in the 2020MkII
processing chain outperforms any comparable link in any
competitive product. When the links are combined the MkII
is vastly superior.
