"Excellent product!!"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I’ve been using this I/O for a few weeks now. I fond it to be very easy to use right out of the box. I’ve used it on Mac, PC, and an IPad. I’ve had no problem with any of the OS’s. The metering on the LCD screen is very helpful. The only down side is that there aren’t any markings on it. However this can be fixed by using tape and marking it your self. Just use a VU meter when doing so. I used an A440Hz tone to do this. The controls on the box are clearly marked and easy to understand. Setup was easy for all platforms and the drivers play nice with the many other drivers for other I/O’s that I use. It’s also worked well with the many of the software platforms that I use as well (pro tools, cue base, logic, etc.) Latency times are excellent, and the sound quality is incredible. I use it for primarily SFX, and VO’s. I needed something very portable and light weight, as well as, bus powered. I take it in the field a lot. It gives me more function than a field recorder without the extensive setup. I’m trying to figure out how to use an external power source to extend the battery life on the iPad but, it seems to be good when you have a full charge. The power button is very helpful in this situation. All in all, it is a very good product and would highly recommend it. Spend the money. It’s worth it.
