IN 2

Powerful Desktop USB Interface for the Home Studio

Powerful Desktop USB Interface for the Home Studio

The Aphex IN2 is a USB interface conceived with the home project studio in mind. It includes 2 of Aphex’s Class A microphone preamps with top-quality analog to digital conversion and 2 DI instrument inputs, alongside a host of other amazing features and I/O connectivity all built into a compact chassis. Simple and easy to use, just connect it to your computer and get ready to record! 

Input Versatility – We squeezed all the features we possibly could into the Aphex IN2. 
Along with the 2 Class A mic preamps we have also included a 75Hz HPF, -20dB Pad, 48V Phantom power and an optical compressor in each channel. 
There are 2 DI high impedance inputs for recording guitar and bass located at the front of the unit. Unique to the IN2, both channels of the IN2 feature an optical compressor which, when engaged, will help control the dynamics of your input signal while adding pleasing density and weight. 

Class A Preamps – In most desktop audio interfaces, complaints that microphone preamps peak too easily and sound thin are quite common. This is never an issue with the Aphex IN2 – our 2 Class A mic preamps have ample headroom and sound big and warm. The multicoloured LEDs on top of the unit display input level and glow red when the preamp is peaking.

Total Monitoring Control – The Aphex IN2 was designed as a complete desktop recording solution for your home studio, which is why we have included additional monitoring features not found in other desktop interfaces. 
There’s a mono button for making sure your mix is mono compatible and a dim switch for lowering the volume of the monitoring output. 
The unit also features a stereo headphone amplifier taken from our HeadPod4. The S/PDIF output on the back of the unit is perfect for connecting to your HeadPod 4 to expand the number of headphone outputs available to you.
