The Sound Devices 664 is an industry standard portable field mixer with the option of up to 12 inputs. It comes with six high-bandwidth, low noise microphone preamplifiers with phantom power, limiters, high-pass, pan, and direct outputs per channel. There are four output buses, Left, Right and Aux 1, Aux 2, transformer-balanced for freedom from ground loops and multiple output connectors, including dual multi-pin. The 664 has a built-in production recorder, and records all inputs and output buses: 16 record tracks total. All 12 input channels can now be used without the optional CL-6 input controller.
