You can enter standby by pressing the power button on the remote or holding the display for three seconds. Please note: For the bypass to function correctly, the source and preamplifier connected to the HP-5.2 must utilize the same connection type (RCA or XLR). EXPLORING THE FEATURES Studio is an innovative suite of features designed to elevate the headphone listening experience, implemented entirely in the analog domain: Crossfeed: Blends L/R channels to recreate a soundstage similar to listening through loudspeakers. Harman: Optimizes equalization specifically for headphone acoustics. Superflat: Linearizes the frequency response in the high range. DF (Damping Factor): Adjusts the damping factor to perfectly match the impedance of your headphones. The Balance function offers precise volume control over Left/Right channels, allowing you to manage output according to your hearing needs or specific driver characteristics.
