The Pace-Car 2 is a high-performance reclocker that can reduce jitter for virtually any digital source device, including CD Transports, iPod(Wadia), Apple TV, Sonos, Squeezebox, Duet, Olive, Transporter, Lynx, direct from Mac-Mini, and Macbook.
Empirical Audio has led the market in designing low -jitter high -performance Computer Audio interfaces since 2002. We were the first exhibitor at CES to use exclusively computer audio.
It is jitter that makes digital audio sound "veiled" or fatigueing. Once it is eliminated, the result is like cleaning the film from a window, improving clarity, dynamics and 3 -D as well as bass tightness.
The Pace -Car was primarily designed to address the deficiencies in the various WiFi devices on the market, but has much wider application, even extending to multi -channel synchronous streams to support computer -generated speaker crossover software.
The Pace -Car is legendary for reducing jitter to extremely low levels in digital music streams. Two audio magazine editors use the Pace -Car or Pace -Car 2 for their digital audio reference: Positive -Feedback and Stereo Times. Positive -Feedback did a comparison of several USB converters and the Pace -Car:
The Pace -Car 2 improves on the original Pace -Car with new discrete and separate power regulation and improved grounding to further isolate the inputs from the outputs. A small switching supply has been replaced with a linear for lower noise.
The Pace -Car 2 is a buffer -memory device that temporarily stores the digital data stream in order to reclock it out using a local clock with very low jitter. The jitter on the inputs is not particularly important. The data is not modified in any way.
There are three modes in which the Pace -Car can be used:
1) word -clock synchronous
2) master -clock synchronous
3) asynchronous tuned
Depending on the source device, one of these modes will be used.
The Pace -Car 2 supports 44.1kHz and 96kHz sample rates as standard (provided the clocks are present), with 88.2, 176.4 and 192 as optional.
