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.

Philips - Direct Control

Better than belt. Better than direct.
What's better than belt and direct drive? The best of both in one turntable. The specs of direct drive with the acoustic and mechanical isolation of a belt drive. Until now, unheard of. But now you can hear it all on Philips exclusive new Direct Control turntables.

Philips' exclusive Direct Control electronic drive system
In all Philips Direct Control turntables a mini-computer at the driving disc constantly checks and re-checks the platter speed. Instantly correcting for any variations in line voltage, frequency, pressure on the platter, temperature - even belt slippage. That's how all Philips Direct Control turntables keep the speed constant and accurate.

Direct Control Free-Floating Subchassis.
Specially designed to give Philips Direct Control turntables superb acoustic and mechanical isolation. To cushion the platter, the tonearm - and protect your valuable records - from unexpected jolts, shocks and knocks. And to keep the rumble remarkably low.

Direct Control - Total Turntable Design
But Philips doesn't stop there. For us Direct Control is more than an exclusive new drive and suspension system - it's a completely new concept in total turntable design. Direct Control is specially designed straight, low mass, tubular aluminum tonearms, with very low friction bearings. To track even your most warped records accurately.

Direct Control Electronic Features.
Direct Control means reliable electronic touch switches for silent, vibration-free operation. Accurate electronic pitch controls. Digital and LED indicators to monitor platter speed and identify functions. And photo-electronic sensor to initiate the automatic tonearm return.

Direct Control Record protection
Philips even built in an accurate stylus pressure gauge, to keep the pressure off your valuable record collection. Nobody ever thought of that before. But philips thinks of everything.
