1. 412 AM FM Tuner e 24 preset stations 12 FM 12AM e 25kHz tuning steps e NAD link e Blend function The NAD 412 has evolved from the award winning 402 The 402 was named Best Tuner 1994 by What Hi Fi Improvements include a new high clarity display and a re designed chassis The NAD 412 is a superlative product and it out performs many other tuners that cost far more Employing high quality components in it s simple circuit topology give the unit and it s predeccesor the noise free low distortion performance that have made NAD tuners famous Only the most essential functions are employed resulting in an uncluttered front panel of a product that is simple to use 24 stations 12 FM 12AM can be entered in the preset mode They are stored in a non volatile memory which allows the preset stations to remain in memory even if the unit is unplugged from the mains supply Unlike most other tuners the 412 tunes in 25kHz increments This coupled with crystal oscillator controlled digital frequency synthesis makes for precise tuning and enables the user to fine tune to their desired stations with ease A centre tune LED indicates that the 412 is accurately locked to the transmitted signal The SEARCH mode allows the 412 to tune to the nearest strong station up or down the band whilst the TUNE mode allows rapid scanning through the band In both modes the software wraps the frequency band around allowing you to skip directly from2. the top of the band to the bottom or vice versa When attempting to listen to weak stations sometimes the background noise can become annoying and spoil the listeners enjoyment of the programme The BLEND function reduces this noise whist still retaining adequate stereo separation NAD link is provided enabling the 412 to be remotely controlled by another NAD product that is also fitted with NAD link and which has an IR sensor Specifications NAD 412 FM tuner section Usable sensitivity 50dB quieting 60dB quieting Capture ratio IF rejection AM supression Selectivity alternate channel Subcarrier suppression okt and 38k THD Signal to noise ratio sant IHF weighted Frequency response Gonz 1sktz Channel separation ak AM tuner section Usable sensitivity Selectivity Image rejection Signal to noise ratio cmv input THD 30 mod 1mV input IF rejection Physical Specifications Dimensions wx ux Net weight Shipping weight Power consumption Mono Stereo Mono Stereo 45dBf Mono Stereo L R Stereo L R Mono Stereo 1 5pV 2 5pV 30 0pV 7 0pV 100pV 5dB 75dB 54dB 78dB 60dB 1KHz 50 mod 0 2 1KHz 50 mod 0 3 1KHz 50 mod 0 2 73dB 70dB 0 7dB 40dB 7pV 19dB 36dB 45dB 2 46dB 435 x 76 x 295mm 3 6kg 4ke 15W NOTE NAD reserves the right to change specifications or design at any time without notice All specifications are those in effect at time of printing
