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:

Heavy chewer approved.
Style: Ball, Size: Medium (Pack of 1)
My pomsky will destroy a toy in minutes. Ropes, and the "indestructible" nylon type stuffs are no match for my furry shark. This ball has stood up to him like David. He loves the crunch and it is so much more tolerable than a squeaker. These will be a staple in his toy box - Chuckit toys are really the most durable dog toys I have found in three years.

Dogs love them
Style: Ball, Size: Medium (Pack of 2)
Our dogs love these. What’s great is that you can add more plastic (like from water bottles) if the plastic starts to fall out from the center. If you have a chewer, though, these won’t last you long. Our shepherd mix loves these and then starts to pull the rubber apart the more she plays with it. Our other dogs treat it normally, though, and those ones last forever. They also get some decent height when bounced, and they make a unique whistling noise when thrown.
