Explorer²
Hear More

Meridian’s new Explorer² is the successor to the popular and widely acclaimed Explorer pocket USB DAC. Explorer² replaces a computer’s audio outputs with a USB-powered DAC (Digital to Analogue Converter) featuring over 30 years of Meridian’s digital expertise in high-quality audio circuitry. Explorer² includes digital clocking derived from Meridian’s award-winning Reference Series components, for precise timing of digital signals.

Featuring a dramatically increased complement of technologies, Explorer² with full MQA support, is able to incorporate the full suite of Meridian’s audio enhancement technologies to provide a more realistic, natural sound than ever before.

Key Features

Meridian’s unique Apodising filter can actually fix errors in digital recordings, making any music sound more alive, regardless of its source.

Master Quality Authenticated [MQA] is a revolutionary end-to-end technology that delivers master quality audio in a file that’s small enough to stream or download. What’s more, it’s backwards compatible, so will play on any device. And because it’s fully authenticated, you can be sure you’re hearing exactly what the artist approved in the studio.

Meridian Resolution Enhancement technologies including upsampling and apodising filters.

Compact, elegant and rugged metal enclosure. 

 

 

With its extensive Research and Development programme Meridian has pioneered the development of a host of innovative audio technologies many of which feature in today’s Meridian products.

Filters are critical in digital audio. Commonly they introduce distortion and harshness because of "pre-ringing". Early digital recordings suffer from harshness too, due to primitive filters. After painstaking research, Meridian developed a special filter that avoids pre-ringing, so it can be steeper, cleaning up the effects of early filters. The result: a better, cleaner sound from recordings old and new.

MQA is a technology that captures the full magic of an original studio performance. Using pioneering scientific research into how people hear, MQA delivers master quality audio in a file that’s small enough to stream or download – the days of sacrificing quality for convenience are over.

Uses a complex digital filter to double the rate of samples from the source to improve resolution of the finer details in the record. This means that even with a standard source such as CD using our upsampling technology we are able to significantly enhance the listening experience.
