Having bought a pre-owned Sony FM stereo tuner through eBay, it came without any manuals. It soon became clear that to get the best from this excellent tuner I needed a decent manual because much of the operation was not intuitive to a newboy to hi fi like me. I managed to download the official Sony multi-lingual manual from Owner-Manuals.com with no problem at all - a really quick and easy service. I'm very glad I did because I found out all the operations of the tuner and was then able to not only set it up quickly but also to get much more from it that poke-and-hope trialling would ever achieve. In my book $4.99 very well spent.

This manual is immaculate in it's accuracy. Everything is written very clearly and easy to understand. Written by a professional who wants to convey a clear and easy to understand message!!

This Manual (as downloaded) is both informative and comprehensive and has proved to be extremely useful. thoroughly recommended.

everything is ok, thank you very much! Product is good, no problems with download!

Great site, I always find all the manuals I need and i can't find anywhere else. PDF for the Sony PCM 3348 is complete and scan is good quality. Thank you!
MODEL BG4.1 UNIDIRECTIONAL CONDENSER MICROPHONE The BG4.1 microphone utilizes an advanced condenser transducer design for use in professional instrument sound reinforcement and project studio recording. Its electret cartridge has a wide frequency response for natural sound reproduction, and its high sensitivity and low noise make it an ideal choice for producing quality demo tapes. The BG4.1 also maintains a cardioid polar pattern throughout its frequency range which ensures high gain-before-feedback and maximum isolation from undesired sound sources. Operating voltage is supplied by phantom power from a mixer, or an internal AA battery for 10,000 hours of continuous use. Typical applications for the BG4.1 include acoustic guitar, drums, stringed instruments, and vocals (when mounted on a stand). GENERAL RULES FOR MICROPHONE USE 1. For optimal signal-to-noise ratio, place the microphone as close as possible to the desired sound source. 2. For the best gain-before-feedback and isolation from undesired background noise, aim the microphone toward the sound source and away from undesired sound sources (Figure 1). The BG4.1 features a cardioid polar pattern which is most sensitive to sound directly in front of the microphone, and least sensitive to sound directly at 180_ . 3. For the purest reproduction of sound, use only one microphone per sound source and use the fewest number of microphones necessary for the application. 4. For maximum isolation, keep the distance between microphones at least three times the distance from each source to its microphone. 5. Placing the microphone close to the sound source improves bass response (Figure 2). This phenomenon is known as proximity effect and can be used to achieve a fuller sound, and to change the bass output of an instrument without using tone controls. Proximity effect is also especially good for vocals during soft passages where emphasis is needed. 6. Placing the microphone too close to acoustically reflective (smooth, hard) surfaces will result in a poor frequency response and will increase the chances for feedback. T minio mize this effect, place microphones as far as possible from acoustically reflective surfaces. 7. Add an external windscreen when using the microphone outdoors to reduce wind noise. 8. It is important to keep foreign particles out of the grille and the windscreen because they may alter the frequency response of the microphone. Also, avoid exposing condenser microphones to heat and high humidity.
