The popularity of the Apple iPad, iPhone and iPod Touch has spawned a plethora of add-on devices for recording musicians that run the gamut from simple, single-input devices to external microphones. The iU2Interface from Tascam takes the idea still further and delivers an audio/MIDI interface containing many features found in the company’s best-selling USB audio interfaces, including a pair of great-sounding microphone inputs.
Accessing the recording app of choice running on the iOS device is simple. Vocalists can connect condenser microphones to a pair of XLR inputs using the included adapter cables, with switchable phantom power available. For the guitarist or bassist, a dedicated instrument-level input is provided, while the keyboard player can connect a synthesizer or electric piano via dual balanced line inputs.
The built-in microphone preamp and analog-to-digital converter deliver far better sound performance over the stock audio inputs, with less noise and distortion. MIDI I/O is also provided and a zero-latency monitoring path allows musicians to hear themselves directly through the unit without any delay. A headphone output is available for monitoring.
Additionally, an S/PDIF digital output provides connection to a digital mixer or other digital recorder. Included with the unit is a USB cable, an iOS dock connection cable, two XLR to 1/4" conversion cables, along with a pair of converter cables for MIDI I/O. The unit will also work with conventional Mac and Windows computers via the USB 2.0 connection.
