I played around last weekend with all kinds of different setups. My wife and I were toying with the idea of an online concert.
I started with my T8S USB into my webcasting laptop (which has one of those "all-in-one" TRRS jacks for audio input/output, and I didn't have a proper cable/jack combo handy.) It has an acceptable internal webcam (not great, but then I have a face for radio ... my wife, however, deserves better video quality.) We stood about 6 - 7 feet back from the laptop to frame the picture correctly.
I have 6 inputs: Two Shure Beta 58a's in 1 & 2; Squier Telecaster in 5; Taylor 424ce in 6; and stereo backing tracks into 7 & 8 (I normally run the tracks into USB, but couldn't since the T8S's USB out was being used for the webcasting system.) We monitored with an L1 Compact connected to the T8S headphone jack -- very handy for independent volume control!
I struggled getting acceptable volume and mix into the laptop. The mixes in my test broadcasts were never quite what I thought i was hearing from the Compact. Also, since I didn't have a long USB cable handy, I found myself frequently walking back and forth from mic to music laptop to mixer to webcasting laptop to start/stop recordings and to change settings, and getting tired of it.
I also tried a T1, and I perceived that it pumped more volume into the USB (not sure if that was really true, but I was running out of time to research all the options before going live.) I then hit upon an idea -- connect the webcasting system to the T1 via USB, then connect the T8S L/R main outs via TRS cables to the T1 channels 4/5, set the trim and master volume on the T1 ... what a difference!
While it looked like a Rube Goldberg setup, it fit what we were doing: I had the T8S and music laptop next to me to choose tracks, adjust levels, mute channels & FX, and adjust the monitoring level; the T1 was next to the webcasting laptop and was pretty much left alone. Reverb settings on the mics from the T8S were passed through the T1 to the webcast. Although we lost stereo by going through the T1, the majority of our audience (mostly seniors) doesn't use earbuds anyway and wouldn't notice the difference.
The live webcast far exceeded our expectations in terms of sound quality as well as audience numbers. As often happens, when we played it back later, we found out how out of practice we were! The overall volume, while acceptable, was lower than other similar webcasts. We did find later while the T1 trim was properly gain-staged, we could have pushed the channel and master volumes much more.
I'm going to get a long USB cable and test the T8S alone again the next couple of days. Overall, we're very pleased with results!
