The XD-2 DSP has enough processing headroom to power two independent channels of dynamics and EQ at 96kHz, which can be two analog recording inputs with monitoring, stereo outputs for an analog or digital two-track master, or two channels in and out all via USB. . Each channel has three separate DSP modules--a compressor/limiter, a gate/expander, and a four-band parametric EQ--all of which can be arranged in any order along the signal pathway.
In addition, each input channel has a high-pass filter (HPF) that is activated or de-activated by the channel HPF buttons on the front panel of the XD-2. Each HPF can be set to the desired roll-off frequency, and a secondary Low-Pass Filter (LPF) can be either enabled or disabled from the software as well.
