SONY STR-K750 Digital Audio/Video Control Center

This unit is an absolute MONSTER for any audio application. I used it specifically for an AM/FM stereo receiver and CD player but works great for a surround sound home digital theatre system as well. (speakers not included). There\'s just so much you can do with this unit. Manual can be downloaded from the net.
Here\'s the manufacturers description:
DESCRIPTION:

Here\'s the high power and extraordinarySTR-K750P5.1 AV home theater AM/FM stereo receiverbySony.

5.1-channel AV receiver that delivers a total of 300 watts – 100 watts of power per to the front, 100 watts of power to the center, and 100 watts of power to the rear speakers.Features built-in decoding for DTS, Dolby Digital, and Dolby Pro Logic II formats, making it a reliable, budget-friendly option for home theater or surround sound setups

But big power is only one important attribute of this new receiver - you also get an FM front end that performs with outstanding stability and sensitivity, thanks to the use of a pair of dual gate MOS FETs in its RF amplifier and mixer, an advanced FM IF section that includes three 2-element ceramic filters and a large scale integrated circuit, plus a multiplex section for FM stereo broadcasts that uses the innovative and advanced phase-locked loop IC for excellent separation characteristics.

The result is a flawless kind of sound that is unmatched in tonal quality by any comparably-priced receiver now on the market, plus the radiant good looks ofSonydesign and human engineering.

TheSTR-K750PbySony: Something extra everywhere.

POWER AMPLIFIER SECTION:

A major feature of the power amplifier section is the servo operational amplifier system.

TheSony STR-K750PAmp sectionis a low distortion, high power, stereo integrated amplifier with wide dynamic range. Combining advanced circuits with a new design concept provides no-nonsense musical performance at a pleasing price.

Precision CR tone circuit, a high performance amplifier for wide dynamic range, and simple to use basic features make the popularly pricedSony STR-K750Peven more appealing as a worthwhile investment in yesteryear\'s advanced Hi-Fi electronics.

This distinctive package of plenty includes up-to-the-minute circuitry throughout its handsome construction, and then gives plenty of power to boot:continuous power output of300 watts total – 100 watts of power per channel to the front, center, and rear speakersplus, from 40 Hertz to 20,000 Hertz with no more than 0.7% total harmonic distortion.

TUNER SECTION:

The major feature of the FM tuner section of theSony STR-K750Pis the Quartz Locked system which detects ant difference in frequency between IF signal and the reference signal generated by the crystal oscillator. Another important feature of this equipment is the Touch sensor circuit.

The FM MPX Decoder uses the design principle of the \'phase lock loop\' applied in the circuit. It has no inductances or capacitances which cause phase shifts and distortions. Any phase dislocation that might occur is automatically detected and compensated by a loop circuit. This results in an unprecedented high degree of stability irrespective of temperature or humidity changes.

Also, theSony STR-K750PTuner section amplifier 2-stage front end incorporates a 5-gang variable capacitor and three dual gate MOS FETS. A capacitance controlled double tuned circuit is inserted between the RF amplifier stages. Those features produce impressive characteristics such as usable sensitivity of 38.3dBf (Stereo) and 18.3dBf (Mono), a Separation of 45dB, and a selectivity of 60db.
