Short signal paths minimise interference, volume is adjustable in precise 0.25dB steps, and a digital bypass mode is available to all analogue sources. Digital-domain tone control with Tilt, five-band parametric equalisation and mono or stereo subwoofer support with selectable frequency and slope give fine control over the system.\u003c\/p\u003e\n\u003cp\u003eInputs include network, USB, AES\/EBU, coaxial and optical digital connections alongside XLR and RCA analogue inputs, and the high-performance onboard MC\/MM phono stage supports up to two phono inputs. HEOS Built-in provides network streaming and AirPlay 2. Automation is handled via DC triggers, CAN Bus and RS-232 over RJ-45, and the anodised aluminium chassis features an adjustable-brightness touchscreen
