Usage: audio timing system (Smaart live)
UTILIZATION
Plug and play
GETTING STARTED
No soft bp
OVERALL OPINION
I decided to invest a year ago in a card with XLR inputs with 48v power supply, to calibrate the audio systems on Smaart Live festival. To my regret the electronic characteristics were not there yourself. This card sulfur from a serious design problem of the internal 5V supply that is made around a switching system, generating a noise on the analog outputs on XLR and greatly exceed 106dB S / N announced by the datasheet. This noise and all the more important when food 48v triggers. The linearity is not the appointment of inputs (measured + / -2 dB from 30 to 550Hz) unacceptable for the acquisition card for audio.
I do not use more and do not think selling either, so I bought one of the uac202 behringer and the measurements are very satisfactory. No breath and amplitude curves in / out are straight. The only downside are RCA inputs and there is no 48v, a small preamp will do the trick.
Good research
