Audiophile 4-channel preamp-processor-DAC. Analog, phono, digital, and high-definition (HDMI, Ethernet, USB) inputs. Fully parametric equalizers can be used to mitigate artifacts from the room and specific loudspeaker placement. Depth/Immersion Control adds a new dimension to adjust spaciousness. The two additional channels can be used flexibly as center, height, surround, and subwoofer channels.
