AES3 (also known as AES/EBU) is a standard for the exchange of digital audio
signals between professional audio devices. An AES3 signal can carry two channels
of PCM audio over several transmission media including balanced lines, unbalanced
lines, and optical fiber.
S/PDIF (Sony/Philips Digital Interface)
The consumer version of AES3 which uses coaxial cables to carry the audio signal.
TOSLINK (Toshiba Link)
TOSLINK is a standardized optical fiber connector system. Also known generically
as an “optical audio cable” or just “optical cable”, its most common use is in con-
sumer audio equipment (via a “digital optical” socket), where it carries a digital audio
stream.
Headphone Membrane Weight Compensation
AMÁRI’s 2 high-power stereo headphone outputs (on XLR connectors) feature in-
dividual volume controls (capped at 20dBu max), with digital trim and selectable
output impedance – from -4.6 to 85.3 Ohm, available in 17 control steps. These op-
tions let you configure AMÁRI for ideal compatibility with your favorite headphones,
matching their impedance for best performance. AMÁRI’s high-fidelity headphone
driver chip offers fully differential input (per amplifier). It is a dual-amp design, opti-
mized to eliminate possible temperature drifts and deliver differential signal quality.
The headphone outs also feature dual DAC architecture for maximum performance.
