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.

Akai GXC-310D cassette deck


Double Capstan Drive Cassette Stereo Tape Deck

Professional Wow&Flutter characteristics with closed loop double capstan drive system

 

The employment of the refined tape drive system of this model is usually limited to a few professional type open reel models. However, Akai decided to include this feature in a discriminating number of our cassette models for matchless cassette performance when combined with the other quality mechanisms incorporated in these models.

With this system, the recording/playback head is positioned in the center between two capstan and pinch rollers. This not only results in better head-to-tape contact, but also provides constant tape tension and the section of the tape between capstans is kept free of vibrating interference which may occur outside of the closed area during tape travel.

Functioning integrally with this system is an anti-vibration hysteresis synchronous motor for reduced wow and flutter, modulation interference, and tape speed variation as well as two unusually stout flywheels and flat belts for capstan drive. (When compared with the usual flywheel and V belt system, wow and flutter is small, but rotating energy is increased). Further, the revolutions detector for automatic stop is an electro-magnetic system control lead switch so that the load applied to the reel table is small for even better wow and flutter characteristics.

Thus, these features result in incomparable tape travel stability and constant tape tension and speed with an amazing wow and flutter specification of 0,07% WRMS

 


Like all Akai cassette machines, the GXC310D features the Dolby Noise Reduction System to reduce tape hiss to a virtually inaudible level, give a bigger frequency response Akai's ADR (Automatic Distortion reduction) system which varies the equalisation at high input levels to cut distortion and extend the dynamic range at high frequencies,

Its many other features include a peak Level indiator Automatic Stop Limiter switch, Mic/Line Input Selector for a wider dynamic margin and less noise. Pause Control, output Level Control for perfect matching with any amplifier input, Tape Run indicator, Memory Rewind and Index Counter direct function change controls and a bias equalisation switch for low noise, CrO₂ or ferrichrome tape.

Again, there's a specially designed perspex dust cover (DC310) as an optional extra.
