Thank you for choosing Senal.
The Senal XU-1648 XLR-to-USB Interface enables you to
plug your dynamic or condenser XLR microphone into
your computer’s USB port. The 16-bit/48-kHz sampling
rate delivers studio-quality sound, and the interface
provides switchable phantom power for condenser
microphones. The headphone output allows latencyfree monitoring, with a headphone level for volume
control and a monitor level to adjust the balance
between playback audio and the microphone.
