What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Pioneer CT-4141 cassette deck

 

The potential of cassette stereo sound reaches its zenith with this outstanding new deck from Pioneer, a thoroughly professional unit with multiple advanced features. The first Pioneer deck of its kind with built-in Dolby noise reduction unit, the CT-4141 offers one of the widest frequency response ranges of any deck in this time on the market, 30 to 16,000 Hz when chromiumdioxide tape is used. The Dolby system is employed to eliminate irritating tape hiss and noise and does this most effectively without sacrificing important tonal quality. All in all, cassette tape has never sounded better than with this complete deck, which is also equipped with a chromium tape selector that allows you to use this new kind of tape manufactured especially for near-flawless sound reproduction, wide frequency response and extra-wide dynamic range. When matched with the Dolby unit, chrome tape will provide a cassette sound that is the equal of expensive open-reel tape decks. Other standard and standout features of the CT-4141 include a ferrite soild tape head, designed for long service life, as well as an electronically controlled DC motor that assures a very high Signal-to-Noise Ratio. There is a tape running pilot light that provides assurance that all is functioning well, and a "skip" button that enables you to use the fast-winding function while monitoring sound reproduction, when the mode key has been set to "play". Noo other deck on the market, at the price of the CT-4141, offers so many exclusive and important features for superb sound reproduction.

Ferrite Solid Head for Long-life

The high performance chromium tapes possess a 50% higher density of magnetic particles than conventional cassette tapes, and can therefore impair the conventional tape head over an extended period of time durability of the head is thus a key concern for all contemporary decks and the  CT-4141 has one of the most durable of all. The ferrite soild head employed in the CT-4141 will give lifelong service and durability when used with any kind of tape. Additionally, you can expect a variety of other important benefits from this head, including little loss of high frequency bias, magnetic power and improved frequency characteristics especially in the high frequency ranges. The surface of this head is mirror-finished, to protect your tapes and to afford an extremely smooth head touch to the tape. This fine surfacing also contributes to dust-free usage af all tapes, and helps to suppress background noise that often occurs from magnetization.
