Kurzweil KM-1U USB Condenser Microphone

Kurzweil KM-1U is a large-diaphragm USB condenser microphone designed for vocals, podcasts, streaming, voice-over and home-studio recording. Its 34 mm pure gold-plated pressure-gradient capsule and cardioid polar pattern capture a focused signal from the front while helping control room reflections and background noise.

Powered directly through USB 2.0, the KM-1U works as a plug-and-play recording solution without requiring a separate audio interface. Its 24-bit A/D/A conversion and support for 44.1, 48, 96 and 192 kHz sample rates provide detailed recording quality. The built-in headphone output enables zero-latency monitoring while recording.

Mute, output gain and headphone volume controls, together with a 100 Hz low-cut filter and -10 dB pad, make the KM-1U suitable for speech, vocals and louder sound sources. It is a complete and flexible USB solution for content creators and home-studio users.
