Thanks! Is it possible to see power/voltage vs distortion in the software to measure power output of a headphone amp?
You can measure power/voltage vs distortion in REW, but only after calibrating the software.Thanks! Is it possible to see power/voltage vs distortion in the software to measure power output of a headphone amp?
Yeah, I already expected that it can’t handle lots of power, but I would only use it for measuring dongles and portable stuff anyway@juliangst oh and also note that the Cosmos Load board was designed for dongle DACs like the 9038S/D, Meizu HiFi, etc. It can not withstand multiple Watts.
I need your help! I use the Cosmos as an ADC for my external mic preamp through XLR input. The specs said 10V input max in the Cosmos, however my preamp specs are +28dbu output at half gain. Is it save when I did that. According to my very low audio signal after recording, I didn't hear any clipping or anything bad.Headphone amps will be not optimal for that AUX input due to way too low voltage <<43Vrms. Such stuff is better to measure with XLRs inputs 1.7-10Vrms.
Well, I tried about 20Vrms 1kHz sine for 10S and Cosmos ADC with sensitivity 10V did survive.I need your help! I use the Cosmos as an ADC for my external mic preamp through XLR input.

Do you have any solution for me to use your ADC with my mic preamp for recording since the max output of the mic preamp can go up to 32Dbu. For example the 2.5mm as an alternative?Well, I tried about 20Vrms 1kHz sine for 10S and Cosmos ADC with sensitivity 10V did survive.
Do I have to open the Cosmos to do it sir? My preamp has 1 XLR output . Does that means I connect pin 1 of the XLR cable to somewhere in the cosmos?The AUX input has minimal sensitivity of about 35Vrms(ADC gain setting should be 1.7V), it is fine for your 32dbu=31Vrms.
But you'll need to tie the GND wire of ADC to GND of the preamp.
Thank you Ivan!!!Cosmos ADC XLRs also have pin#1 GND, I even have printed that on the front panel, also there is printed 2.5mm AUX pinout: View attachment 246005
If possible, lower the preamp gain more - this will probably benefit in lower noise also from the mic amp. Check your gain structure. If the preamp can drive low impedances it will be better to set the dip switches for lower input sensitivity.I need your help! I use the Cosmos as an ADC for my external mic preamp through XLR input.

Actually, [email protected]. 0dbfs about 1.8Vrms.I record into Cosmos at it's most sensitive setting (1,4v)
Thank you for your experiences. i'll do it in post digital gain.Have to correct myself - the lower sensitivity on Cosmos, the higher impedance... so thats good
