All-In-One Convenience

With its portable size and ability to run on battery power, the SD-2u is ready to travel anywhere, giving you high-quality recording and editing in one standalone unit. The built-in stereo mic makes audio capture easy, while high-performance stereo speakers provide convenient sound playback of your recordings, WAV music files, lesson material, and more.

Quality Recording, Intuitive Operation

The SD-2u records CD-quality audio direct to widely available SD/SDHC memory cards. It’s also super-simple for anyone to operate thanks to the Easy Guide feature, which provides clear onscreen instructions that guide you through various operations. Easy Guide covers recording and overdubbing functions, creating minus-one tracks for practice and karaoke, setting proper input levels, and more. You can even choose among six different languages for the display: English, German, French, Italian, Spanish, or Japanese.

Connect External Mics and Other Devices

While it’s designed for pro results as a standalone unit, the SD-2u also provides connections for integrating external devices to suit various applications. Two XLR/TRS combo jacks allow you to connect your own mics (with phantom power available if needed), including a stereo field-recording mic such as the CS-15RS. There’s also a stereo mini-mic jack with Plug In Power, plus stereo RCA LINE IN jacks for connecting an instrument, music player, or another audio source.

Essential Training Tools

The SD-2u is equipped with powerful features for manipulating audio playback, providing useful tools for building music skills, learning languages, transcribing spoken-word audio, and more. You can independently adjust the speed and key with exceptional audio quality, perfect for slowing down passages to learn difficult parts or changing the key of music to suit your voice. Use A-B Repeat to play audio sections over and over, and turn on Center Cancel to create minus-one tracks for practice and karaoke fun. There’s also a newly developed Center Focus feature, which isolates center-located sounds in music tracks to make them easier to hear and learn.

Carrying Case and More

The optional CB-CD2E Carrying Case gives you durable protection while transporting the SD-2u, plus handy storage pockets for accessories like batteries, extra SD cards, the AC adaptor, and the remote control.
