XMOS Integrated High Speed USB 2.0 PHY giving 480Mbps data-rates and USB Audio Class 2.
PCM 24~32bit/384kHz (Max.) sampling rates supported. (* Note-32bit will not be shown on computer)
USB 2.0 high-speed compliance with DSD (2.8M,5.6M and 11.2M data supported), with the ability to sample 44.1, 48, 88.2, 96, 176.4, 192, 352.8 and 384 kHz sampling rates, indicated by LEDs on the front panel
ESS ES9018K2M SABRE32 Reference Stereo DAC : Audiophile-grade (DSD /2.8M, 5.6M, 11.2M supports)
32bit 384kHz DAC Chip
Analog-to-Digital Converter: The STRATOS sports a high-performance CS5340 ADC chip for high resolution recordings via analog inputs including phono, AM/FM radio, or other analog signals to PC or MAC hard drive (24bit/192kHz Max.)
Ultimate high-end grade linear volume control: 2-channel electronic volume allowing the volume to be preset for each input (Phono, Line, USB).
Three Powerful Headphone Amplifiers: STRATOS has three powerful TI TPA6120A2 headphone amplifiers: a pair handle the left and right channels of the XLR (4-pin) balanced output (non-switched), and the third powers the 6.3mm Stereo phone jack output (switched). (TI TPA6120A2 driving from 12 to 600 ohms at >120dB dynamic range)
ASIO (Windows); Plug’n Play (MAC)
Line , ADC and DAC OPA : TI NE 5532 OP Amp, PHONO OPA : JRC NJM2068DD OP Amp
S/PDIF Coaxial and Optical input: If the playback sample rate cannot be set at source, the Coaxial and Optical LED will indicate (Max. 24bit/192kHz sampling rates supported)
Optical S/PDIF output (for USB, Optical and Coaxial) 24bit/192kHz Max.
Convenient Clip signal Toggle switch for Recording Attenuation: Adjust the recording attenuation to avoid any distortion during recording: -6dB, 0dB or +6dB (Rec/dB signal light comes on when input level exceeds circuit Gain).
Phono Preamplifier: The STRATOS features a phono equalizer for recording your precious LPs. Switch between Moving Magnet (MM) and Moving Coil (MC) or Line input
Dual External power supply :
Power supply-1: 5V DC from USB bus powered USB chip only.
Power supply-2: External AC/DC Switching Adaptor output DC 15V / 800mA / 12W

STRATOS has no setting for gain to match different impedance headphones.
We recommend using 12 ohm to 600 ohm impedance headphones.

IMPORTANT:

 When connecting the STRATOS directly to a power amplifier or power speakers, a “pop” noise may be heard from speakers when powering on or off the STRATOS. To avoid the “pop” noise and potential damage to speakers, please follow these instructions:
– Switching OFF the STRATOS: First, switch off powered speakers/power amplifier: second, switch off STRATOS.
– Switching ON the STRATOS: First, switch on STRATOS; second, switch on powered speakers/power amplifier,
