AM STEREO (original) (raw)

New custom MW-2A PLL medium wave AM broadcast band home consumer electronic tuner is available, which has phase-locked loop electronic digital tuning system, hand-made craftsmanship, and a very special AM stereo section! This solid state audiophile component tuner is quite unlike anything else: it is wide band, and has a Motorola C-QuAM stereo decoder, showcasing natural sounding high fidelity, with very low audio distortion! Our goal was not to build a low fidelity AM tuner for this offering. This new tuner also does not share its chassis with any FM tuner components. It is exclusively the AM tuner!

Audition one of our tuners, and you will be astounded: the AM section of this meduci even sounds better than AM HD Radio in their hybrid analog/digital (MA1) operation mode. Because it has none of the digital data audio compression artifacts that make HD Radio sound swimmy, wishy-washy, and artificial in the MA1 service mode.

In all honesty, virtually all consumer AM tuners available today, or produced in the past, sound like you are listening through a paper-towel roller, because these inferior sounding tuners roll-off the high and low audio frequencies. This meduci MW-2A PLL tuner does not eliminate those audio frequency extremes.

Instead of cluttering the front panel with seldom-used buttons and features (such as with some tuners from other sources), this meduci MW-2A PLL tuner concentrates on the essentials, with additional new standard features that increase its curbside appeal:

• WIDE \ NARROW BANDWIDTH SELECTION -- This standard feature allows you to narrow the tuner's I.F bandwidth for night-time conditions or for "DX-ing" weaker stations. Being stuck with one extra-narrow or extra-wide audio bandwidth is not all that practical for the different reception conditions that we encounter on the AM band from day-to-night -- this dual bandwidth feature provides your MW-2A PLL tuner with much more versatile operation. Even listening to a selection at the narrow bandwidth, the recovered audio is far superior to most other consumer AM tuners available on the market today.

• NRSC AUDIO DE-EMPHASIS SELECTION -- Another appreciated standard feature on your new MW-2A PLL tuner is the NRSC front-panel audio de-emphasis curve defeat switch, that improves the overall frequency response from AM broadcast stations transmitting with the NRSC pre-emphasis audio curve. Very few other AM tuners ever incorporated this switchable NRSC de-emphasis feature. NRSC pre-emphasis curve is voluntary in U.S.A, so there is not an easy way to know if the AM medium wave station makes use of it, or not. If the AM station sounds strident in wideband mode, then likely the NRSC curve is being used at that station. Next station on the dial may not be using it, though. For that reason, we leave the NRSC feature switchable, and easy to defeat. This restores the proper audio frequency response, and decreases audio noise up to 10dB at the higher frequencies. This new feature will not remove local interference from a device in your house or neighborhood.

• AUTO STEREO \ FORCED MONO SELECTION -- There may be rare instances when a received mono AM station may false trigger the C-QuAM stereo decoder circuitry into action. In this case, you would want the forced mono selection to be enabled.

• TWIN-T AUDIO NOTCH FILTERS -- Two high-Q sharp RC filters are always engaged to eliminate annoying inter-carrier "whistle" sounds. These sounds would be produced from co-channel and/or adjacent medium wave stations "beating" and creating the new notes during crowded night-time listening periods.

• BRIGHT RED LARGE AM STEREO INDICATOR -- Provides solid confirmation that you are listening to C-QuAM stereo broadcasts (where available). This AM stereo indicator is not present on any other new receiver offered today, however you can find it on the front panel of your new MW-2A PLL tuner!

• RECEIVED SIGNAL STRENGTH INDICATOR BAR GRAPH METER -- This (added option "SSM") integrated feature visible on front panel provides positive confirmation that your very own AM external indoor tunable loop antenna is centered and locked onto your favorite AM station's signal! Simply rotate the tuning knob on your attached loop antenna for the greatest number of green lit bar segments on your MW-2A PLL tuner! This indicator is integrated into the rather large, bright, high contrast 24-segment green digital numeric frequency display (14.2mm, 0.56" height) on the right side.

This new MW-2A PLL tuner has rock solid, precise, and stable operation -- with user interface directly under custom microprocessor control -- and this tuner even makes mono AM stations sound better.

All stations received on your MW-2A PLL tuner are drift-free, thanks to the Motorola digital Phase Locked Loop synthesizer circuit, that provides precise electronic tuning (automatically, of course). This evolutionary feature eliminates ALL microphonics, unstable operation, and tuning drift, thanks to a highly stable quartz crystal oscillator timebase. Your MW-2A PLL tuner does not require any "safe cracker's" touch to selecting desired stations. Also, the tuning range is NOT sharply condensed, which is typically encountered from ALL manually-tuned radios, in the upper end of the broadcast band. Tapping on the tuning knob, or moving your MW-2A PLL tuner, will also not upset the rock solid frequency lock on AM stereo and AM monaural stations.

Either 9kHz or 10kHz continuous electronic station tuning steps are included in this phase stable design, set at the time of production manufacture, based upon tuner's shipping destination during order placement. This is intuitive simplicity for manually rotating the tuning knob to your desired AM medium wave station's frequency. This tuning mechanism does not have any mechanical tuning stops, so you can tune directly, instantly, and simply from the band edges (say from 530kHz to 1710kHz), or anywhere in-between these band edges on the station dial.

We also made several cosmetic improvements to the overall external appearance! These improvements include aesthetically pleasing black exterior, with nice contrasting white lettering on front and rear black aluminum panels. All is housed in new attractive black plastic cabinet, which measures seven inches long by six inches wide by two inches height (179.5mm long by 154mm wide by 51mm height).

This professional quality MW-2A PLL tuner is our most advanced tuner offered to date -- updated and re-packaged to build upon the renowned strengths of our two previous consumer AM stereo tuner models. Most importantly- this new MW-2A PLL tuner has superb ultra high-frequency recovered audio frequency response, that is not found on any other consumer AM tuner nor receiver being sold new today. Excellent sound, ease of use, and convenient features are all wrapped up in this MW-2A PLL wallet-friendly tuner, ready for a devoted audiophile's tuner collection! Your MW-2A PLL tuner is designed for high fidelity reception from local and regional AM stations. With this tuner's dramatically increased audio bandwidth-- undoubtedly, you will hear other sounds that typical common garden variety tuners and receivers simply will not reproduce. In the process of increasing the audio fidelity-- for better listening enjoyment-- any high frequency noise in your reception environment will also be increased. We cannot promise a noise-free listening experience, since every reception environment is different. It is best to get the receiving antenna away from any man-made noise sources for best C-QuAM stereo reception. Both the NRSC and I.F bandwidth front panel switches will also reduce these recovered higher frequency audio noises, when pushed to their "downward" positions.

We strive to earn customers for life. We only want good experiences from our products throughout the world, so we stand behind each and every sale. We support and service our products, if needed. Please let us know if you any questions, or suggestions for this new and improved, re-designed tuner.
