Specifications:
Device purpose: Ultra-low THD+N variable gain buffer for Cosmos ADC
Materials: Sandblasted/black anodized aluminum/laser mark/OPA1612+OPA1656 composite,Viking resistors,Murata, Samsung C0G caps, Taiwanese connectors/relays
Dimensions: PCBA 90x50x29mm104x61x39mm
Weight: PCBA 40g / 160g
Power: USB-C +5V rail, <500mA current
Input:
2 channels balanced 200/100kOhm bal/unbal
3.5mm jack up to 20/10Vrms bal/unbal
If only the left input is plugged, the signal is routed to the right channel as well, to implement MONO mode for Cosmos ADC. Cosmos APU's short cables are suitable for Scaler as well.

16 positions controllable by the knob, in the "Auto" position Scaler works like a ultrafast autoranger(100mS) with the left channel target 4.5Vrms.
The right channel output voltage is ignored. 20Hz-20kHz is the valid frequency range for autoranger.
Frequency Response:
.2Hz-570kHz @ 26db gain +.5/-3db, .2Hz-7..11MHz @ 0db gain 10MHz area depends on a cable(Scaler's output is stable up to 7m of mic cable) capacitance
Residual Noise:
250nVrms(A) @ 26db gain typical
The only indirect measurement method is available at such a low level due to a huge loop gain OPA1612+OPA1656 composite(170db@1kHz/130db@10kHz)
Something like 100x times less than Cosmos ADC or H3 -175db@1kHz at 0db gain
Crosstalk:
Something like 100x times less than Cosmos ADC or H3 -175db@1kHz at 0db gain
L->R -133db, R->L -158db@1kHz unused input is shorted @0db gain

GREAT FOR MY LITTLE ADOPTED DOG!
Color: 6 pack
These little soft dog toys are wonderful for small to medium sized dogs. I recently rescued a dog who had never seen a toy, nor did she know how to play with them and these are perfect. She is a 13 pound half Chihuahua/terrier mix, and she loves to play with these little toys. They’re cute to me and she likes them so that makes me happy.

Cute but not durable
Color: Blue Octopus, Color: Blue Octopus
My dog LOVES the toy and was so excited to get it. It is so cute…but not durable like advertised. My chewer was able to rip a hole by the evening we received it.
We like it…just not excited for the clean up
