The Echo 2 - USB Audio Interface by Echo features 2 inputs, 4 outputs and resolution up to 192 kHz / 24-bit. It can function as a standalone personal mixer, or it can connect over USB 2.0 to a Mac or PC.

The Echo 2 features two built-in preamplifiers that offer switchable input levels for microphones, line-level sources, and Hi-Z instruments. The two 1/4" TRS inputs include adapter cables (1/4" TRS to XLR-F) to facilitate connectivity for microphones. Selectable Phantom Power is available on each channel, but requires that the interface be powered by the included adapter. The Echo 2 can also be USB bus-powered.

The Echo 2 has two balanced 1/4" TRS outputs and a 1/8" TRS stereo headphone output. The output volumes can be separately controlled, and when used with a computer, they can be routed independently. This feature allows monitoring of an alternate source in your headphones, which is especially convenient for DJs. Additionally, the Echo 2 offers near zero latency input monitoring, patching the hardware inputs directly through to the headphones.

For live applications, the Echo 2 includes an adjustable mic stand bracket.
