Pioneer SX-300T receiver

The SX-300T Solid-State 40W Stereo Receiver is a precision made instrument the end result of meticulous research, design and engineering. Hand-made by craftsmen under strict quality control standards to insure you of a personal pride of ownership. All transistorized circuits from the frontend through outputs. Function and performance are superior to any other receiver in its price range. An optional walnut wood cabinet (CA-20) is available.

Features of SX-300T

A unit type employing an abundant numbar of printed circuit boards. FM front-end, multiplex circuit, AM tuner, FM-IF unit, equalizer, tone control, main amplifier, etc., All major circuits are of a complete unit type employing precision printed circuit boards. Troubles due to wiring have been virtually eliminated assuring many years of annoyance fre operation.

Transistorized front end.

Transistorization of FM front-end, which is technically very difficult, has been successfully achieved. The circuit system is of a 3 transistor, separate excitation front end, and a multiplex tuning 4-IF stage, of which 2 stages are limiters with AGC. An excellent sensitivity of 3 µV as per IHF specifications and an image ratio of 55 dB (in 82 MHz). A wide band ratio detection method is employed.

Automatic switching mechanism with multiplex circuit.

Separation of the multiplex circuit is more than 20 dB over a wide range of 40 - 8000 Hz. In addition, an FM mono/stereo automatic switching mechanism, a switching unit employing Schmidt circuit is provided. This ensures unfailing and stable operations. Owing an FM stereo broadcast a separate mono - stereo indicating lamp lights to show it.

Tuning indicator to assure precise tuning.

Accurate and precise tuning is imperative for a noise free clear tone reception of a broadcast. SX-300T is equipped with a high-sensitivity tuning meter for tuning indication.

Low Frequency Output Circuit

The main amplifier adopts a complementary circuit which does not use an input transformer. The OTL system of single ended push pull (SEPP) gives a rich sound reproduction in a wide band of 20 Hz to 20,000 Hz . Other excellent features include: the output power of 40W in music power, (distortion factor is less than 1%), effective output of 15W x 2 (distortion factor is less than 1%), damping factor of 25 (1 kHz/8 Ω )

Newly Designed Speaker Connection Terminal

A screw terminal of conventional type is provided as an output terminal for speaker. Since the terminal itself is designed to serves as a plug, it assures a proper and secure connection.

Various auxiliary equippment that enable you to enjoy magics in the sound Loudness contour assures a rea life sound even as a low level AFC ON-Off switch, jack for stereo headphone, input/output terminals for recording and reproduction with tape recorder and, a connector jack by DIN specifications are provided to make this equipment more versatile.
