Solid well built product. Excellent audio bandwidth and sensitivity. It needs a good FM antenna to sound its best. As with any good audio equipment, the sound is totally limited by the source material which is this case is the broadcast quality. Strong high quality broadcasts sound great.

Features

RDS: The RDS limits itself to the RDS PS (Program Service) and RT (Radio Text) function, both of which enhance ease of operation. The RDS PS will automatically indicate the name of the radio station you are listening to in the display. At the touch of a button, RDS RT will display additional information broadcast by the radio station, such as the presenter, the music playing, etc.

Fine Tuning: With each brief rotation of the C 427's front-panel rotary dial, the tuner will take 0.05 MHz steps for the FM band and 10 kHz for the AM band. You can also use the remote's numeric keypad to directly enter a station's identification number. Auto Search automatically stops at the next strong radio signal and optimizes tuning. Weaker radio stations can be tuned into manually. Stations that are quiet in Mono, but noisy in Stereo can benefit from the "Blend" feature that narrows stereo separation and improves noise. FM Mute eliminates inter-station tuning noise and only allows strong and clear stations to emerge from the silent background.

30 Presets: With 40 presets available, you can store all your favorite radio stations in any combination of AM and FM stations. To avoid having to scroll through 40 presets, the un-programmed (empty) ones are skipped to give you quick access to all your stations. All the preset information is stored in the C 427's non-volatile memory, which means it will remember all of its preset information even if the unit has been unplugged for a prolonged period.

Connections: The NAD C 427 tuner features a threaded F-type connector to connect the included FM wire antenna, and two spring-clip terminals to connect the included AM loop antenna (you can upgrade antennas). The NAD C 427 is fitted with a set of stereo RCA outputs and comes with a 38" audio cable to connect the tuner to your AV receiver. The rear panel IR input (3.5mm), +12V Trigger input (3.5mm), and RS-232 port allow the C 427 to be easily integrated with sophisticated system controllers used in custom installation. The tuner also comes with a detachable 6.5' AC power cord.

Simple Operation: Instead of littering the front panel with seldom-used buttons and features, the C 427 concentrates on the essentials. It features an intuitive user interface with a 24-position rotary encoder knob to quickly tune stations or select preset stations. The included IR remote provides wireless operation of the tuner.

VFD: The C 427 features a Vacuum Fluorescent Display which provides visual information on the settings, conditions, status, and other information relevant to the currently tuned station. The display offer three brightness settings.

Sleep Mode: The tuner's Sleep Mode timer will switch the C 427 to "standby mode" automatically after a preset number of minutes (30, 60, 90, or Off).

Why did you buy this?

Mom is feeling a bit trepidacious about internet radio in lieu of an old fashioned AM/FM tuner on the new receiver. [ Chris  Oct 04, 2018 ]
reviews [ Thomas  Sep 30, 2018 ]
Needed an AM/FM tuner to compliment the new Receiver I purchased. Receiver comes only with FM but needed AM for sports broadcasts. Fantastic features from a fantastic brand. [ Steven  Sep 19, 2018 ]
Good tuner! [ Michael  Apr 30, 2018 ]
To complete my NAD system and the reviews were solid. [ Scott  Apr 12, 2018 ]
This is the only moderately priced good quality FM tuner I could find on the market. [ Loel  Mar 09, 2018 ]
needed a new FM tuner, NAD should be a good bet. [ MARK E  Dec 31, 2017 ]
To go along with a NAD C 165BEE Preamplifier. [ George  Dec 07, 2017 ]
A long time NAD user [ Glenn  Oct 10, 2017 ]
needed just a tuner for my stereo not a reciever [ DANIEL  Sep 17, 2017 ]
Seems like a good tuner,, based on the reviews I have seen. [ PAUL  Jul 25, 2017 ]
I think NAD makes some great stereo equipment...have nothing but good things to say about them. I need a 'new and improved' tuner and i'm betting this one will work very well with my other NAD equipment. [ al  Jun 20, 2017 ]
Reviews, here and elsewhere. [ George  May 31, 2017 ]
To match my NAD c356bee. [ ROBERT  May 12, 2017 ]
Not many am/fm tuners around. This one gets good reviews. Crutchfield has given great service and advice, and stood solidly behind two other recent purchases, both of which had problems initially, but were rectified completely and quickly. Thanks crutchfield. No worries, if there are any problems they will be dealt with quickly and fairly. [ Bruce  Feb 27, 2017 ]
recommended by Crutchfield staff and will fit best with other stereo components [ Cara  Feb 26, 2017 ]
As to the NAD tuner, it's one of the few left on the market and has many more features than a couple of cheaper makes that seem to still be available elsewhere. As to Crutchfield, a very good and reliable company. Kudos to the shipping department on the quality of the packaging of the integrated amp I recently purchased. [ John F.  Jan 31, 2017 ]
Like NAD. Needed a tuner. Would have liked an audio receiver but no such thing from NAD. [ Angus  Jan 24, 2017 ]
I needed a tuner and this was top rated - 5 stars [ Val  Jan 10, 2017 ]
I needed to replace a tuner and the combination of performance specs and price made this the best option. [ Mark  Jan 06, 2017 ]
Building an NAD stereo stack, it was a must-have. [ Rufus  Jul 14, 2016 ]
Just purchased the amp and preamp. Really happy with NAD and Crutchfield! [ Heagan  Jun 15, 2016 ]
Only tuner we could find with RDS [ Carol  Jan 05, 2016 ]
NAD and Crutchfield reputation. Good balance of features and price. [ Robert  Dec 21, 2015 ]
A lot of positive from user reviews. [ KHUONG  Dec 09, 2015 ]
The positive reviews. [ Garth  Dec 03, 2015 ]

8 questions already asked

Not that I'm aware of. Mine has are 2 settings: Bright and dim, and the dimmer button simply toggles between them. [ Mark  May 24, 2018 ]
That would be a disappointing "no, not that I've been able to find". [ Glenn  May 21, 2018 ]
Chris L , no , at least my NAD C 427 cannot . The dimmer control toggles between a low light ( suitable for night time listenlng ? ) and a brighter setting only . [ Bruce  May 17, 2018 ]
Remember that ALL FM tuners sound awful, because that is the nature of the FM signal. I would NOT buy a great FM tuner! Either spend a lot more money and get an HD FM tuner, and spend about the same amount as the C 247 and get yourself a great DAC. My iTunes sounds better through my stereo than the 247 does. But the DAC is not cheap. Crutchfield has a great selection. [ Eric  Sep 17, 2017 ]
I have never owned the MC MR-78, but I do know that the MR-78 was a analog tuner from the 1970's, so that would be heard to beat! Using an indoor dipole antenna, the sensitivity on the C-427 is "OK" at best IMHO. I was able to dial in some fringe stations with it (that I was also able to dial in on my 1970's Sansui tuner). But I was getting some noise on those stations with the C-427 (which was not present on the old Sansui). While I had high hopes and thought I needed this modern day tuner (and there a barely a few to choose from these days), I wound up returning it. If you spend time listening to a better analog tuner, then listen to the C-427 you will hear what I mean. Please note this has nothing to do with nostalgia, this has to do with sound. I personally will forgo conveniences like a remote and station pre-selects for superior sound. IMHO, everything on the C-427 sounded extremely synthesized and compressed, like the audio is being run through a series of filters. AND the sensitivity was just OK. Find an old tuner (McIntosh, HH Scott, Kenwood, Sansui, etc). Find a tech who knows how to service a analog tuner. Have them check it out and service where needed, *AND run a full alignment*, and you will be happy. It is also possible to do this for a little less money than the cost of the C-427 (Say if you end up with a Sansui or Kenwood). [ Roland  Sep 16, 2017 ]
I would rate it okay, not the best, not the worst- with a good antenna (roof-mount) I improved the signal strength a lot and made sure I used a powered splitter to run it to more than one unit. I still sometimes get less-than-spectacular performance, but then it blends mono & stereo modes and that helps. For the $$, it's a decent unit. [ MARK  Sep 15, 2017 ]
Can't give you comparison to MR-78, but can tell you that in the same house I get better reception with NAD than with older Yamaha T-80. Overall, very happy with NAD Tuner for the money. [ Bryan P.  Sep 15, 2017 ]
I don't know the anwser to that question. However, McIntosh gear is a large step better than NAD. I no longer use the NAD C427 in my system. It is in its box in storage. For 2 channel I just have my CD player hooked up to my pre-amp and amp. For home theater, I have a Onkyo RZ-810 AVR which I use its tuner for FM listening. To improve the AVR tuner's ability to get better reception, I use a RCA TV antenna (i.e. rabbit ears) does a fantastic job. So in my mind whether you go with McIntosh or NAD use rabbit ear type antenna. You will have no problems with reception. [ BROOKE E  Sep 15, 2017 ]
Yes. The NAD amps are all flat black (metallic, not shiney black plastic) as is the C427 tuner. (I have a C372 integrated amp and a C427 tuner). [ Joseph  Dec 25, 2016 ]
Don't know. I bought the NAD C 356BEE amplifier. This tuner matches that. [ Gile  Dec 20, 2016 ]
mine didnt [ DONALD A  Aug 17, 2016 ]
it does not include one of those. [ Rufus  Jul 26, 2016 ]
It does have the coax connector for an FM antenna only. It still uses a two wire connection for AM. [ Daniel  Jul 25, 2016 ]
Yes. [ Obie  Jul 25, 2016 ]
Hi Gerald. Sent just a yes answer but intended to also suggest looking closely at the second picture provided by Crutchfield. That picture is the back of the unit and you can see the coax connection on the left. Hope this helps. [ Dave  Jul 25, 2016 ]
Yes. [ Dave  Jul 25, 2016 ]
Yes, I've attached an FM antenna via the coax connection - terrific reception! [ Rick  Jul 25, 2016 ]
Being that your soundbar has RCA inputs it will act as the amp in this scenario. [ Daniel  Apr 25, 2016 ]
DA, This is simply a tuner, nice quality, but does need an amp. Output is straight line level, intended to plug Into preamp/amp. There is an RS-232 serial cable connection to a PC, etc., but I have not used that interface, so cannot help out there. [ Ulf  Apr 23, 2016 ]
Assuming that the soundbar has its own built-in amplifier(s), I believe you would connect the tuner directly to its RCA inputs, assuming that they are not otherwise needed. [ Obie  Apr 23, 2016 ]
I replied yesterday to your question about HDradio, and assumed when I bought this unit that it did bring in HD. So I looked in the manual, and it does bring in RDS, Radio Data System, a small digital input, it is not HD. Sorry for being misleading! The sound is quite good, all I listen to is FM broadcasts, but live in a quite rural area, so stations are oftenquitedistant, but still very good reception. Would appreciate a reply if you find more specific information. Good luck [ Ulf  Jan 05, 2016 ]
no it doesn't support hd radio its a high quality old fashion tuner. I could also do without the v in most audio products. good luck! [ VINCENT  Jan 05, 2016 ]
The NAD C427 does not support HD (digital) radio. I, too, wondered why this seemingly easy-to-provide feature was not available in mainstream, or even somewhat high-end, tuners. [ Obie  Jan 04, 2016 ]
17 1/8" W x 11 1/4" D x x 4" H It is a great tuner! [ Ulf  Jun 17, 2015 ]
Width is 17 inches. [ Obie  Jun 17, 2015 ]
WIDE IS 17.1/8 - DEEP IS 11.1/4 - WIDE IS 17.1/8 AS PER MEASURE BY MYSELF. [ KHUONG  Jun 17, 2015 ]
Dan, you're in luck...the dimensions are 17W x 4 h x 11 1/4 deep. I love mine, hope this helps MCH. [ Mark  Jun 17, 2015 ]
its 17 1/8x3 15/16x12 7/16 hope that helps good luck! [ VINCENT  Jun 17, 2015 ]
The front panel is 17 1/8" wide. [ Greg  Jun 17, 2015 ]
Beautiful tuner. Simple yet brilliant design and features. Initially I did not like that there were no station presets, but now I prefer the unique station-setting and choosing system ( I'd describe it but I would not do it justice.) I've had Healthkit, Dynaco and Adcom tuners previously but without going into specs, the NAD is my favorite. And, given that tuners are becoming increasingly rare, I am extremely glad the NAD C 427 is available. [ Rick  Jul 25, 2016 ]
The unit is well made, great sound. My older NAD had the LED light burn out on the display, so replaced it with this one. Very nice sound, good reception. I'd say it is worth the price. [ Ulf  Jun 17, 2015 ]
We have not received any answers from other customers on your question. I think this will likely come down to the kind of performance you are looking for. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help determine if this tuner is right for you, and discuss other options if it is not.
