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

awesome

I’ve never read a book by this author before, but she knocked it out of the park! Thanks so much for thinking of us readers who are left with book hangovers and just need the next book in the series. I just downloaded the next one. I don’t normally write reviews but this author needs to be out there so everyone can find her. Great book, excellent characters and pacing. Wonderful storyline.

pleasantly surprised!
Format: Kindle
So, I’ve been on the Find Me (WITSEC) book train and trying to find a book to hold me over until the second book comes out and omg now I’m going to have to do the same for THIS book!
I was drawn in from the beginning. The characters, the multi POV (which is one thing WITSEC lacks), the world building! Excellent! I love a good grovel and I think these guys are headed that way now! I can’t wait to see where the next book takes these characters!
Now….what do I do while I wait?

Tip Top Read

Marvelous debut by first time author to me. The story sounds similar to many others, but is written extremely well with enough bite to give it a fresh feel. Told from different POVS, our heroine survives a traumatic event, moves to a more secure location with her mum, and begins to live. She is daring, brave and most of all, true to herself. But then......you have to get the book to find out what happens next!!!!!!

So I really enjoyed the story. It’s unbelievable in some of the torture revelations on things that did happen and things that didn’t happen.
The character development was decent. Having a little more background on the MMCs would have been nice but for what it was it’s fine. I just didn’t connect with them as much as I wanted to.
Lots of typos and misplaced words in the kindle version.
I’ll probably read the next one. I was glad the cliff hanger was not so startling that I felt I had to dive into the next book immediately. I could stop here and be fine with not knowing what happens next. Just assuming she got away.

Unexpectedly original for a mafia book. I thought I read them all but I loved Emmy's personality. I liked her toughness and that she didn't give into the three hassholes, Ares, Hades and Vulc. Emmy and her mom were on the run for over a year when they found refuge with The Pantheon. Her mom reconnects with an old HS friend and while Emmy tries to keep to herself. Ares, Hades, and Vulc notice how different Emmy is from the girls they're used to and instantly want to get to know her and protect. But Emmy and her mom have more secrets then the boys knew and protecting her becomes a full time job. Will they get any benefits from being her bodyguards? High heat with a good storyline. Triggers of kidnapping and abuse.
