A sophisticated mixer for a variety of simple applications.

The overall specs on the console are great—low noise and low distortion. The three-bus routing scheme provides a lot of flexibility, another pleasantly surprising feature in such a small mixer. The 24-bit Lexicon effects sound great too, adding even more value to the mixer, as does the standard Kensington lock slot on the rear of the console, enabling the mixer to be secured in an environment where theft is a concern.

I would feel very confident using this mixer for virtually any AV, meeting, house of worship, theatrical, or corporate setting. If the application doesn’t require dozens of inputs, this mixer still provides a lot of the sophistication that is normally found in larger consoles—definitely worth a look.
