The project uses inputs 0-3, with 0-1 being L+R for input 1 on the codec board, 3 and 4 are L+R for input 2. That sets the board to use TDM for both ADCs and DACs. Probably the safest option is to solder 1 and 3 together from the bottom, with a thin insulated wire. I'm using a thin solid wire, wrapped like the old wire wrap around the pins. And I thought that other people might benefit from it, since this is basically the highest quality we can get out of the board.įirst of all, you need to set the SIP3 jumper on the AD1938 codec board to 96kHz, i.e. I'm using an Amanero Combo384 clone to send I2S data to the board and it works really well for all rates up to 192kHzĪfter having realized that the max core frequency for this board+codec is 96kHz, I started creating a skeleton project to be used in the future.
#Adau raw power serial
With the AD1938 board jumper open, the AD1938 works in 48kHz TDM mode, so you can output all 8 channels (4 stereo signals) on one serial output port from the ADAU1452 But at 96kHz seems to work decently well even for longer optical runs with cables of questionable quality, so that's good For 192kHz optical a 25Mbps receiver is needed. If you want to be on the safe side, use 96kHz maxĪlso, the optical receiver on the board only really works to 96kHz, being a 16Mbps part. From my tests, it works at 192kHz using the RCA input, but I did not take any measurements to check audio quality. Keep in mind that the SPDIF on the ADAU1452 is limited to 96kHz according to Analog Devices. Tweaking crossover parameters for a given configuration is pretty safe to do it's the reprogramming of a configuration that cause the unwanted sounds. If anyone has done a similar project then I would love to read about it.Ĭlick to expand.Congratulations on having a working board! And, yes, when programming there is a real risk to get unwanted high volume sounds, so it's safer to have physical level limitation before an amplifier. I'm thinking of getting a better core board and hooking it up via I2S to some higher quality DAC/ADC boards. This certainly has a lot of potential seeing as MiniDSP boards cost hundreds but I don't think I want to end up using the Lusya boards or similar. When EProm was wiped, had to power on the board with the jumper to turn off self-boot mode.SPDIF input worked when I set the SPDIF_RX registers to restart automatically on relock and audio word length to automatic.Setup the routing matrix for spdif input and used ASRC inputs in the schematic.Config - USBi block, ADAU1452 connected to I2C 0x76, E2Prom connected to SPI 0x1.Removed jumper from Codec board for 48khz mode, 192khz causes it to overheat and shutdown.Hook up SCL, SDA and GND from the ICP3 programmer.Sure ICP3 programmer definitely works for programming both the 1452 and EProm.The outputs are extremely loud and the board occasionally produces tones when programming so pots must be used before an amplifier.
Codec analog inputs are terrible so I'm using spdif input only.Codec board analog outputs are surprisingly good, about
Cheers to Vuki, Xplo5iv, mga2009 and robca for the help. But the point is, it seems insane to me that someone who is (genetically) capable of benching 600lbs would ever struggle with 135 or 225 like I once did.Alright, I have the Lusya 1452 pretty much all working now. But where does that point lie? Is 300/400/500 a genetically unreachable goal for some people? Is 600/700/800 a feasible raw, non juiced goal for some people? How can you tell how far your genetics will take you? If you decide to use steroids, how do you know when you've actually maxed out your potential versus just another plateau?
Is this kind of insanely high lift a result of winning the genetic lottery? Copious amounts of steroids? Years/decades of training? All of the above?īecause it seems like all literature on weightlifting I've read indicates that at a certain point, gains just aren't going to come anymore and you've maxed out your genetic abilities. I was reading an article by Tate, and he was talking about how he was benching 600 and squatting 700lbs in fucking highschool.
