Aeris DAC Features and Specifications
aeris | æ ' ris | n.
Nexus of time and space; dynamic gateway between digital and analogue worlds. HYBRID from Latin aerius – ‘air’ or ‘atmosphere,’ and late Latin aera – denoting an epoch from which time is reckoned.
Isolated Synchronous 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 Ultra Low Jitter on all Inputs
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.
Wide range level control of outputs permit direct connection to power amplifiers.
The USB interface requires no additional drivers to install or maintain/update.
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.
6-Layer Circuit Boards
Multi-layer circuit boards provide extremely low impedance ground and power distribution for remarkably low digital noise contamination.
High-Precision Surface Mount Components
Extensive use of Lead (Pb)-free, low temperature coefficient, active and passive surface-mount components results in significantly smaller loop areas, reduced circuit capacitance and inductance, and introduces less noise than conventional leaded components.
Transformer Coupled Outputs
Transformer balanced XLR line outputs provide outstanding output common-mode noise rejection, eliminate potential ground loops, and ensure compatibility with other equipment.
Rhodium / Teflon Cardas output connectors for both balanced and unbalanced outputs preserve maximum audio signal integrity.
Allows remote control of volume, mute, standby, and input selection.
