Specifications: -

>Device Purpose/Marketing Target:  Ultra-low THD+N Analog to PCM Digital Converter For Audio Measurement, E1DA 9038S/D DACs users, DIYers, Audio Tech Bloggers-reviewers
>Materials: - Sandblasted/Black Anodized aluminum/Laser mark/ES9822Pro/OPA1612/RT6863S, Susumu, Viking Resistors, Murata, Samsung C0G caps, Taiwanese Connectors/Switches
>Dimensions: 104x61x39mm (PCBA 90x50x29mm)
>Weight: 157g (PCBA 34g)
>Power: USB-C +5V rail, <250mA current/separated for ADCiso - power it first!
>Input: - USB bridge Comtrue CT7601CR(ADCiso CT7601PR with native 768K) Custom FW XLR L/R (FDA) up to 10Vrms AUX 2.5mm Jack up to 43Vrms
>Output: USB-C, PCM up to 32b/768kHz/ADCiso has that connector isolated with 8pF Please do not use a screwdriver to fix the DATA USB-C cable, use your fingers instead to avoid overstrength and damage to the USB-C socket.
>Latency: 5mS@192k ASIO4ALL REW Measured as a physical delay/2 from ADC input to the 9038D output
Input Ranges/Impedance: - 1.7Vrms  640Ω 2.7Vrms 1kΩ 3.5Vrms 1.3kΩ 4.5Vrms 1.66kΩ 6.7Vrms 2.46kΩ 7.6Vrms 2.82kΩ 8.5Vrms 3.12kΩ 10Vrms  3.48kΩ 43Vrms 13.6kΩ Note: Unbalanced impedance about 30% less.
>Frequency Response:  0.8Hz-320kHz @ 32b/768kHz -3db, depends on the interpolation filter setting
Please refer to the calibration files.
SNR=DR@MONO: -
Grade A 128-129db(A)
Grade B 126-128db(A)
Grade C 125-126db(A)
Grade 0   >129db(A)
 
STEREO mode has 3db worse SNR/DR. Measured at 32/48 AP2700 THD+N@1kHz@-0.5dbFS SR48kHz BW 20-20kHz   0.00007%, SINAD >123db typical for Grade A, 122db Grade B THD@1kHz@-0.5dbFS BW 22-22kHz   <0.00003%(0.3-0.2PPM) typical for 32b/48kHz all harmonics level -135-145db
>Crosstalk: 
< -140db@1kHz /ADCiso <-153db
 
if not used inputs are shorted Windows 10 doesn't need the driver but Windows 7 does and the driver installation may require manual installation. So, if you are not ready for that the good idea just update W7 for W10.
