QIEC POWER RECEPTACLE: The power cable shipped with the converter connects into this socket.
RFUSE HOLDER: Replace only with 1 AMP 220 Volt similar type.
TGROUND TERMINAL: Chassis Ground. Some installations may be helped by connecting a wire from this terminal to the preamplifier. Also this may require that the third pin mains ground be disconnected. The easiest and best way to do this is a 3 pin to 2 pin adapter available in most hardware stores. Keep in mind that this is slightly dangerous in a
UAT&T INPUT: Digital Glass Fiber Intputs. Very recommended if you have the choice. This is not a TOSLINK input. These connectors require a quarter turn clockwise to lock. They can be fragile so some degree of gentleness is best when connecting / disconnecting or moving the converter.
VAES / EBU INPUTS: Balanced transformer floating 110 Ohm digital inputs. Use
110 Ohm cable only. Some people suggest disconnecting the cable shield at the male XLR that is connected to the converter or connecting the shield through a good .1 microfarad capacitor.
WS/PDIF / AES SWITCHES: Each channel should only have either an AES or SPDIF input and not both. The switch should be up if AES is used or down if SPDIF is used. The switch matches input impedance and level to established standards. This minimizes cable reflections and jitter.
XS/PDIF INPUTS: These are floating transformer inputs. Use 75 OHM COAX cable designed for digital or as a lesser alternative good video cable. Do not use standard audio interconnects. While these cables may pass the digital data, they will likely increase the jitter quantity because they are not designed to pass signals in the tens of megahertz. Digital data requires a 5 megahertz bandwidth minimum and significantly higher for good quality square wave signals.
