FMR-1 AM/FM Reciever (FM Stereo)
The FMR1 Stereo conversion allows 4 speaker stereo from AM/FM, iPod, MP3, CD, and Bluetooth input.
Designed to meet automotive OEM and SAE performance specifications, the FMR-1 represents a no compromise design. All critical components are full automotive OEM grade parts, not lower cost, lower quality parts designed for aftermarket/consumer products. Every aspect of the design and operation of the FMR-1, no matter how insignificant was scrutinized, resulting in a product that performs beyond the expectations of even the most demanding user.
Through the use of sophisticated algorithms and a custom RealTimeOperatingSystem (RTOS), the FMR-1 offers unprecedented levels of features and performance. Working equally well with any original tuner (inductive, capacitive and resistive) the FMR-1 offers smooth and precise tuning rivaling the best analog tuners available. Installation time is significantly reduced since the FMR-1 easily adapts to just about any radio configuration from the 1930's thru the 1980's. Signal Seeking radios like the Delco Wonderbar and Ford and Crysler Town & Country radios are fully supported including features like sensitivity controls (Town & Country). By combining the unsurpassed performance of the FMR-1‘s AM/FM receiver with its high performance microprocessor, it finds the stations every time. The addition of subwoofer jacks are availiable as well.
The automotive grade receiver offers such features as noise blankers which help eliminate ignition and generator/alternator noise and an automatic bandwidth filter that continuously adjusts from narrow to wide for optimum performance in all situations. Meeting industry performance specification like SAE J1113-42, the FMR-1 cannot be damaged by battery reversal, double battery jump starts, alternator disconnects (load dump), etc. Even if a careless mechanic accidentally connects the battery up backwards, the FMR-1 is completely protected.
The digitally controlled power amplifier provides up to 4 X 45W of output power and is fully protected against over-voltages, shorts between lines as well as to ground or power. It is controlled by the onboard microprocessor and intelligently monitors the speaker connections and makes decisions such as enabling or disabling the balance and fader controls based on these readings. It uses a unique Class SB topology similar to standard Class AB while using only 1/3 the power at normal listening levels resulting in less heat being generated.
Five fully buffered line level outputs, four for front/rear channels and one for subwoofer, allow the FMR-1 to drive out-board amps for those who wish to add even more audio power. Stereo auxiliary inputs are provided for adding other audio sources such as iPod's, MP3 players, CD players, satellite radios, etc
The FMR-HV1 supply is used to power the high voltage seek relays used in many late 1950's Delco Wonderbar radios. The FMR-HV1 is a current limited supply that works with both the low impedance and high impedance style relays. With it's 52V open circuit output voltage, even the high impedance style relays will operate normally without having to weaken the return spring. Unlike most switching supplies that operate at 20-40kHz causing noise across the AM band, the FMR-HV1 uses an automotive switching regulator operating at 2MHz. Since this frequency is above the AM band, the FMR-HV1 cannot interfere with AM reception. The FMR-HV1 is fully self contained and requires no external components. It is designed to wire directly between the FMR-1 and the seek relay. It's ultra small size and high efficiency allow it to be easily mounted inside the radio.
