Description:
The I-O features two high-quality, active balanced inputs with 50 dB of computer adjustable gain in precision 1 dB steps. These input gains are monitored directly by Smaart allowing the user to retain accurate SPL calibration while varying measurement signal input levels.
The inputs employ a Neutrik combo jack (XLR – 1/4-inch) to accommodate both mic and line level input signals, each with switchable 48-volt phantom power on the XLR inputs for measurement mics and a 20 dB pad on the 1/4-inch to accommodate line level signals.
The Smaart I-O also features two active balanced XLR outputs capable of providing +8.2 dBu (2 Vrms) max level signal for playback or excitation sources.
Powered by the USB port of your computer (or via the optional 5 VDC jack), the Smaart I-O provides a compact and portable measurement-quality input for a Smaart rig.
