NAD C426 owner manual Rear Panel

1FM ANTENNA TERMINAL: Connect the supplied wire “dipole” FM antenna to the FM antenna terminal using the supplied “balun” adapter. It will usually work best when mounted on a vertical surface such as a wall, with arms fully outstretched forming a horizontal “T” perpendicular to the origin point of the signal.

2AM ANTENNA TERMINAL: Connect the supplied AM loop antenna to these terminals. If an external AM antenna is used, make connections to the AM and GND terminals in accordance with the instructions supplied with the antenna. Refer also to the item about ASSEMBLING THE LOOP ANTENNA at the LISTENING TO AM/FM RADIO section of the OPERATION page.

3OUTPUT (L, R): Connect to the corresponding analog audio input of an amplifier, receiver or stereo system.

4RS-232:Connect this interface using RS-232 serial cable (not supplied) to any Windows® compatible PC to allow remote control of the C 426 via compatible external controllers. NAD is a certified partner of AMX and Crestron and fully supports these external devices. Check out the NAD website for information about AMX and Crestron compatibility with NAD. See your NAD audio specialist for more information.

5IR IN: This input is connected to the output of an IR (infrared) repeater (Xantech or similar) or the IR output of another component to allow control of the C 426 from a remote location. Most NAD products with IR OUT are fully compatible with the C 426.

6+12V TRIGGER IN: This input allows the C 426 to be switched remotely to standby mode and ON by ancillary equipment, such as an amplifier, preamp, AV processor, etc. The controlling device must be equipped with a 12V trigger output to use this feature. Connect this +12V trigger input to the remote component’s corresponding +12V DC output jack using a mono cable with 3.5mm male plug.

7AC MAINS INPUT: The C 426 comes supplied with a separate AC Mains cable. Before connecting the cable to a live wall socket, ensure that it is firmly connected to the C 426’s AC Mains input socket first. Connect only to the prescribed AC outlet, i.e., 120V 60 Hz (for 120V version models of C 426 only) or 230V 50 Hz (for 230V version models of C 426 only). Always disconnect the AC Mains cable plug from the live wall socket first, before disconnecting the cable from the C 426’s Mains input socket.

If you intend not to use the C 426 for long periods of time, disconnect the AC mains cable plug from the live AC wall socket.

WARNING

If the male plug of the mono cable (with or without +12V DC) is connected to C 426’s +12V TRIGGER IN, the Standby button in the front panel as well as the corresponding ON/OFF function keys in the remote control will be disabled. Unplug the mono cable to maintain normal power ON/OFF function procedures.
