IK Multimedia iRig Keys I/O 49 is a 49-key controller keyboard with a full audio interface built in, combining full-size velocity-sensitive synth-action keys with a balanced XLR microphone input at 3.2 kOhm supplying +48 V phantom power and 46 dB of gain, a 1 MOhm Hi-Z instrument input with 27 dB of gain, and two balanced 1/4 in. TRS floating line outputs.
The keyboard and the interface are the same box, so the desk only loses space once.
A songwriting setup normally needs a controller keyboard and an audio interface, two power situations and two USB connections. iRig Keys I/O collapses that into one instrument. The keyboard plays software and hardware, and the same chassis records a microphone or an instrument at the same time.
The keys are full-size with a velocity-sensitive synth action, which is unusual at this footprint. IK specifies the 49-key model as substantially smaller than the closest competing controller with full-size keys, and around 25 percent lighter, which is the practical argument for it in a small room or a travel rig.
The audio side is real rather than token. The microphone input is balanced XLR at 3.2 kOhm with 46 dB of gain and +48 V phantom power at plus or minus 4 V, input noise at -100 dB RMS, and 20 Hz to 20 kHz response within 1.5 dB. The instrument input is unbalanced Hi-Z at 1 MOhm with 27 dB of gain. Outputs are two balanced TRS, floating, with automatic level compensation.

Why Choose iRig Keys I/O 49 Over a Separate Keyboard and Interface?
Space, cable count and travel. One device, one connection, one thing to set up. For a small room or a mobile rig that is a real advantage, and the audio specifications are good enough that you are not paying for the convenience with quality.
Who Is iRig Keys I/O 49 For?
Songwriters and producers who record vocals or guitar alongside programmed parts, mobile studios, and anyone building a compact rig around an iPad or a laptop. The 49-key version suits players who want a usable two-hand range.
Can It Power a Condenser Microphone?
Yes, +48 V phantom at plus or minus 4 V with 46 dB of gain. That covers most studio condensers and dynamic microphones for close work.
How Much I/O Does It Have?
One balanced XLR microphone input, one Hi-Z instrument input, two balanced line outputs and a headphone output, alongside the MIDI keyboard itself.
Connections
| Microphone input | Balanced female XLR, pin 2 hot, +48 V phantom |
| Instrument input | 1/4 in. TS, Hi-Z, 1 MOhm |
