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.

Nakamichi BX-125E

The BX-125 follows the Nakamichi BX series design philosophy of pursuing the highest performance at the lowest cost.

Employing a special Sendust laminate core record/playback head and a single capstan transport, the BX-125 provides wide, flat frequency responsenout of 20 kHz. Dolby B and C noise reduction are both included guaranteeing excellent signal to noise ratio. And like any other Nakamichi deck, 30 critical parameter adjustments are made on each unit to provide the accurate record/playback performance you have come to expact from, nakamichi.

Utilizing the most useful features from both the BX-150, the BX-125 is further testament to Nakamichi's committment to creating the best sounding beat quality cassette deck at an affordable price.
