All-in-One production station including an integrated high-definition audio interface. In addition to a professional velocity-sensitive keyboard with full-sized keys, the two extremely compact all-in-one production stations, iRig Keys I/O 25 and iRig Keys I/O 49, feature a built-in 24-bit/96 kHz high-definition audio interface as well as touch-sensitive sliders, knobs, buttons, and 8 velocity-sensitive, backlit multicolor LED drum pads. The keyboards have an XLR combo input with adjustable gain, including 48 volts of phantom power, allowing for the connection of a microphone, electric guitar, or other instruments to be recorded directly to a Mac, PC, iPad, or iPhone using the integrated 24-bit/96 kHz audio interface. There is one balanced stereo line output for signal transmission to external speakers and a headphone output available. Ideal for mobile producers or live applications, power is supplied via USB, batteries (4x AA), or an optional power supply that simultaneously charges the connected iOS device. In addition to a comprehensive software package worth approximately 750 euros (iRig Keys I/O 49) or 550 euros (iRig Keys I/O 25), which includes SampleTank 3, Miroslav Philharmonik 2 CE, and T-Racks Deluxe, a sturdy iPad/iPhone stand is also included, which slides directly under the keyboard to position the iOS device at the appropriate height and angle above the keyboard. Thanks to the included Lightning and USB to mini-DIN connection cables, both iRig Keys I/O models are ready to use "out of the box" with all common DAWs and iOS apps.
