Jeff Rowland Aeris DAC
Great condition, original packaging, remote and manual.

AERIS DAC

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.

The Aeris is the product of a close collaboration between
Jeff Rowland Design Group and Holm Acoustics, a Danish company founded by
Thomas Holm that specializes in signal processing products for high end audio
applications.

The Aeris is much more than the successful result of a
synergistic collaboration between the two companies. The high degree of
complementary synergy between the two teams working in parallel can only be
defined as a case of true organic design.

AERIS DAC
FEATURES

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.

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.

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.

OUTPUT
CONNECTORS

Rhodium / Teflon Cardas output connectors for both balanced
and unbalanced outputs preserve maximum audio signal integrity.

REMOTE
CONTROL

Allows remote control of volume, mute, standby, and input
selection.
