Apogee Duet 3
One of the sleekest interfaces on offer today, the Apogee Duet 3 comes armed to the teeth with recording power. It comes with studio-grade AD/DA, rock-solid digital clocking, and a pair of best-in-class microphone preamps with +65dB of gain. Each mic pre comes equipped with Advanced Stepped Gain Architecture that provides greater bandwidth before encountering any distortion. Ready for the real star of the show? The Duet 3 comes equipped with hardware DSP, so you can fine-tune your sound right at the input stage with no latency. That’s still not all; you get Apogee’s ECS Channel Strip including EQ, compression, and saturation — optimized by Bob Clearmountain himself. Your purchase also includes Control 2 software and Apogee’s Channel FX plug-in.
