Positive Grid, the creator of BIAS and JamUp Pro XT, today introduced its JamUp Plug HD, a studio-quality guitar and bass interface for use with recording and performance apps on the iPad, iPhone and iPod Touch.
The compact JamUp Plug HD device improves on Positive Grid’s earlier JamUp Plug by offering a 24-bit/48kHz USB digital audio solution. The improved resolution enhances signal-to-noise ratio (98 dB RMS), eliminating feedback issues and, according to the manufacturer’s press release, “bringing the manufacturer’s JamUp and BIAS apps to their full potential.” The interface was also designed for maximum compatibility with other mobile processing and recording apps, including GarageBand, AmpliTube, AmpKit, Auria, Cubasis, Audiobus, Loopy and more.
The JamUp Plug HD also features an input level control and three-color LED for quick visual monitoring. A green LED = the JamUp Plug HD is connected, ready and working with the software; orange = the signal level has been optimized for the instrument; red = the input level is too high.
Positive Grid’s new interface allows musicians to “crank it up” and be ready to rock on literally any current iOS device. The JamUp Plug HD docs directly with the iPhone 4 and 4s, iPod Touch 4, and iPad 2 or 3 via its 30-pin connector, and also supports newer iOS devices via Apple’s 30-pin-to-Lightning adapter.
