The Aphex Model 2020MkII Broadcast Audio Processor

Processing in the 2020MkII - Vastly Superior

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.

Additional Features

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

Our Press

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.

Model 2020MkII Processing Chain

Leveling

•Frequency Discriminate Leveler*

•Dynamic Verification Gate*

•Sticky Leveler*

•Jump Ahead*

•Adjustable Rate

•Adjustable Gain Correction Range

Works like the perfect board operator smoothly riding gain without any processing artifacts (pumping, breathing, ducking, hole punching).

Multiband Compression

• Wave Dependent Compressor*	• Band by Band Release Times
• Post Crossover Multiband Technique*	• Adjustable Band by Band Summation Mix
• 4 Adjustable Crossover Bands	• Selectable L-R Linking (None, Elastic, Hard)
• Adjustable Drive	• Selectable Band to Band Elastic Linking

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.

2020Mk II specifications

Aphex Systems has long been a trusted name in the pro audio industry, and the 2020Mk II microphone preamp is a testament to their commitment to innovation and quality. Building on the legacy of the original 2020 model, the Mk II introduces several enhancements that appeal to sound engineers and musicians alike.

One of the key features of the 2020Mk II is its ultra-low noise operation. This preamp employs advanced circuitry to deliver an exceptionally clean signal path, ensuring that your recordings maintain clarity and detail. This feature is particularly valuable when working with high-gain microphones, as it reduces the risk of unwanted noise and distortion.

The 2020Mk II also boasts an impressive dynamic range, allowing it to capture both subtle nuances and loud transients with ease. This dynamic range is complemented by a variable gain control, enabling users to dial in precise levels for different sound sources, whether it’s vocals, acoustic instruments, or drums. Additionally, the preamp includes a 48V phantom power supply, making it compatible with a wide range of condenser microphones.

Another standout characteristic of the 2020Mk II is its built-in high-pass filter. This feature is invaluable for eliminating low-frequency rumble and controlling proximity effect when recording vocals or instruments. With selectable frequency options, users can tailor the filter to suit their specific recording needs.

In terms of connectivity, the 2020Mk II features both XLR and 1/4-inch outputs, allowing seamless integration into any audio setup. The robust build quality also ensures that the unit can withstand the rigors of both studio and live environments.

Moreover, the preamp is designed to add warmth and character to recordings. Aphex's renowned "Big Bottom" and "Aural Exciter" technologies are integrated into this model, providing an added dimension to audio that is often sought after in professional recordings. This technology allows engineers to enhance bass response and restore high-frequency clarity, adding depth and presence to the overall sound.

Overall, the Aphex Systems 2020Mk II microphone preamp combines cutting-edge technology with practical features, making it an essential tool for any audio professional. Whether in a studio setting or during live performances, its reliability, versatility, and superior sound quality make it a valuable asset for capturing exceptional audio.
