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.

Aiwa AP-2300 turntable

Semi- Automatic Direct Drive turntable

Features:

High-efficiency D-D Linear Torque Motor - wow and flutter below 0,035% (WRMS)

Super-solid resin cabinet with revolutionary "Space Saving" design

Fully-adjustable insulator feet

High-sensitivity J-shaped tonearm

Viscous-damped cueing

Full Front Operation

Variable pitch control ±3%

The pitch control knob provided lets you adjust the player's rotation precisely to the standard 33-⅓ or 45 rpm speeds, but there's another big advantage; pitch can be changed by as much as plus or minus 3 percent. Use this control when accompanying the record on your guitar or other instrument, or to vary musical pitch according to listening preference.

 

Easy-to-read stroboscope design

To add to the AP-2300's clean, simple appearance, the stroboscopic markings along the platter have been reduced from the usual 4 rows to 2. when employing the pitch control to adjust rotation speed, the knob should be moved until the upper or lower row of markings appears to be standing still. This indicates precise setting to the 33-⅓ and 45 rpm rotation speed , respectively.

 

Exclusive "Rec-Sync" disc-to-cassette automatic recording mechanism

The Ap-2300 was designed for use with other Aiwa component, but goes a step beyond mere matching for appearance sake; by connecting the cord provided with the unit from the special "rec-sync" jack at the rear panel of the AP-2300 to most Aiwa cassette deck models, player-to-cassette recording can be commenced automatically in tandem with the lowering of the played tonearm of the disc. Synchronized recording operation - it's another reason why Aiwa -built components work superbly together as well as separately.
