User manual NAD C420

[. . . ] Warning: To reduce the risk of fire or electric shock, do not expose this unit to rain or moisture. The lightning flash with an arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. the exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. Do not place this unit on an unstable cart, stand or tripod, bracket or table. [. . . ] NAD components equipped with 12V output triggers are fully compatible with the C420's 12V input trigger. Before making any connections to any 12V trigger input or output, make sure all components are disconnected from the AC mains. Failure to observe the above may result in damage to the C420 or any ancillary components attached to it. If in doubt over the connections, installation and operation of the 12V trigger output consult your NAD dealer. AC LINE CORD Plug the AC power cord into a live AC wall socket or to an AC convenience outlet at the rear of your amplifier. Most NAD system remote control handsets with an On/Off toggle button or separate On and Off button will be able to switch the tuner from On to Stand-by and vice-versa. This information is retained for several weeks, even if the unit is switched off completely or unplugged. When switching power On, the C420 will go back to the station last tuned to before the unit was turned off. This will allow you to make timer recordings using an external timer and recorder. POWER STATUS INDICATOR The Power Status Indicator will light up green when Power is on. When the tuner is switched to Stand-by mode (through either a remote control or the 12V trigger input) the indicator will light up amber. BLEND Weak or remote stereo radio stations are sometimes received with noise and hiss as the antenna signal is too weak. By switching the tuner to mono will reduce the amount of noise and hiss but at the expense of any stereo information. The NAD Blend feature will allow you to reduce the amount noise and hiss but still retain some level of stereo separation, instead of mono. The Blend button toggles between engaging or disengaging the Blend feature; when engaged, "BLEND" lights up in the display. MEMORY The Memory is used to store stations into the Preset Memory bank and to store user defined names for non-RDS Preset stations. When Memory is pressed during normal operation, the Preset number and the red "MEMORY" indicator will flash in the Display Panel. If no other buttons are pressed within 12 seconds, the tuner will revert to its previous state. FM MUTE/MODE This button combines two functions; it switches the tuner from Stereo to Mono and disengages the muting circuitry at the same time. The muting circuit will mute the tuner in between radio stations when searching or tuning. The muting circuit however may suppress very weak radio station signals. If a weak station is in stereo it will have a high level of background hiss. [. . . ] If no other buttons are pressed within 12 seconds, the tuner will revert to its previous state. The Memory Presets have a memory back-up, so they will remain stored for several weeks even if the Tuner is switched off or unplugged from the mains supply. Any unused Presets will be skipped; this avoids having to scroll through empty presets. Press only the display button again (within default time of 5 seconds) to confirm you want to delete this preset. [. . . ]
