The sE Electronics X1 USB houses a hand-made capsule and onboard 24-bit/192kHz USB interface for direct-to-computer recording with studio quality results. No external interface is needed -- simply plug the X1 USB into your Mac or PC and get rolling for Podcasting and bedroom recording. Monitor what you're tracking with zero latency thanks to the built-in headphone amp, and when things get a little loud or muddy simply switch on the -10dB pad and fixed bass rolloff to get right on top of the mic for intimate, in-your-ear recordings.
