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

False advertisement of Real Batana oil 😡
Color: A, Color: A
This product is NOT real Batana oil , it smells like a hair relaxer it’s more of a Clay formula which Batan oil is more of a thicker formulaI. I don’t recommend the purchase of this product .This is what the product looks like after allowing it to sit in the microwave, it did not melt into an oil. This is the result of what it looks like after removing it from the microwave in picture number two.

THIS STUFF WORKS!!!!!!
First of all - RUN, DON’T Walk & get this. IT WORKS!!! I kid you NOT, that I can literally feel sprouts of hair growing out of the roots of my head! After washing my hair And drying it, I part my hair into several sections and gently massage it into my scalp. After at least a day or so, I can feel the tickle in my scalp, it feels like grass slowly growing. I have plenty of hair, but I would love to actually see this product used on someone who doesn’t have hair like me. I am using the product because of a thinning spot that I have from a sew-in that I have had multiple times, and getting it parted in the same area for over a period of time. You can Not beat this product, especially for the price.

Don't not purchase!!!!
Color: A
This is product has over ingredients, its made in China and the shelf life is 3 years! No naturall product has a shelf life of a 3 years or any storing instructions. Just an FYI when buying any product, the ingredient that's the most in the product is the first on this list of ingredients WATER is the first, Batana Oil is second to the last. the packaging say 100%, 100% what? Its truely not Batana Oil. I am sending this back ASAP and working on my own mix for my hair growth. I am dealing with scared alopecia and have been searching for things to help with my hair growth. I am tried of companies thinking they will take my money. I was not able to see the ingredients until I recieved the package, which is not a terriable way to sell a product.

We love this stuff
Color: A, Color: A
My baby had an infection in his hair that he got once he started daycare. We tried everything to kill the fungus. It got so bad I had to take him to the doctor and they finally gave him some antibiotics and medicated shampoo. His head was so sore and tinder he didn’t want anyone to touch his head. So imagine trying to wash his hair everyday. The shampoo killed the fugus and took his hair out where it was. I purchased this product. IT REALLY WORKS!!!!!! We’ve been using it a few weeks and we definitely see a difference.
P.S I went and purchased the whole set

I like it
Color: A
I'm unsure how it affects hair growth since I've only had one jar. It does leave hair moisturizedand soft. It has a really nice scent.
