TECHNICAL FEATURES

IsoSyncECS

Isolated Synchronous Error Correction System. Based upon an 

asynchronous buffer, voltage controlled crystal oscillators,  and a 

24 bit D/A converter – all under the precise control of an FPGA 

(Field Programmable Gate Array) running proprietary algorithms.

BIT PERFECT AND 

VIRTUALLY JITTER 

FREE

!

Bit perfect conversion with total jitter output noise of less than 10 

picoseconds RMS from any input – USB, TOSLINK, and SPDIF.

MULTI-STAGE 

ISOLATED POWER 

SUPPLY

Main power supply is isolated inside an external machined 

aluminum chassis. Eleven precision high-speed regulators 

provide low impedance and  low noise “point of load” DC current 

to all analogue and digital circuits.

ISOLATED AUDIO AND 

DIGITAL CIRCUITRY

Left and right channel audio output circuits, digital processing, 

and D/A conversion circuits are isolated within individual milled 

aluminum pockets resulting in exceptional EMI shielding, and 

thermal stabilization.

VOLUME CONTROL

Wide range level control of outputs permit direct connection to 

power amplifiers.

DRIVER-FREE 

OPERATION

The USB interface requires no additional drivers to install or 

maintain/update.

CROSS-PLATFORM

The USB interface is plug-n-play with all operating systems, 

including PC, Mac, or Linux.

MACHINED ALUMINUM 

CHASSIS

Precision-machined chassis milled from a solid block of aircraft 

grade 6061-T6 aluminum, provides exceptional thermal stability, 

RFI/EMI shielding, and resonance control.
