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.

Onkyo TA-2028

 A wide range of Onkyo's advanced technology has gone into the creation of the TA-2028 Stereo Cassette Tape Deck. Its superbly quiet transport system is teamed with up-to-date noise reduction systems to ensure noise-free sound reproduction. You'll also find a deck adjustable to any cassette tape type, including the newest high-position and metal tapes, thanks to Onkyo's exclusive Accubias system. This and many more valuable features make this tape deck a great value and a fine addition to any high quality home entertainment system.

Computer Controlled Tape Transport with Two DC Servo Motors.
The 2 DC-motor transport system is designed for quiet operation without annoying mechanical noises when stopping and starting. The use of a special "silent solenoid" means that the unit doesn't need a large current when transports starts, which helps avoid hum and induction noise. A customized microcomputer controls transport mode switching, assuring quick response to commands from the transport keys. Computer control also allows you to switch directly between any two transport modes without pressing the stop key in between.
Accubias for the Best Sound Possible from Any Tape.
The normal and high tape bias selector settings found on most decks are not always matched to the unique characteristics of many of today's recording tapes. Onkyo's exclusive Accubias allows  the user to fine tune the bias current for optimum recording results. With a simple Accubias adjustment you will obtain the flattest and widest possible frequency response from each different kind of tape.

Dolby B and C Noise Reduction.
Besides the conventional Dolby B noise reduction, the TA-2028 featuresDolby C NR as well, to battle both high frequency and mid range noise. It also helpsprecvent distortion due to tape saturation.

Two Repeat Play Modes
Single and Full repeat modes allow you to repeat a single song or to listen a second time to a whole cassette side. The clearly marked repeat mode buttons assure that repeat operations are smooth and error-free.

Automatic Music Control System (AMCS)
If you want to slip forward to anorher track, locate a specific song or scan the contest of a cassette tape al. Press the AMCS button. The deck will automatically detect the silent spaces between songs and stop brieffly at the beginning of a song to play about 10 seconds of music and skip ahead. When the desired spot onthe cassette si reached, press the play button and normal playback resumes.
