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.

Thorens TD 124

 Never before has a turntable won such worldwide acclaim as the Thorens TD-124.  A brilliant example of Swiss precision engineering and craftsmanship. Superbly different, the TD-124 offers a host of exclusive features never before achieved in any other turntable, meets the most exacting demands of broadcasting. Its durability and performance specifications exceed NAB standards for studio equipment.

In the TD-124, Thorens has incorporated many outstanding features that open way for discriminating music lovrs to new and greater enjoyment from their music systems.
The TD-124 is unmatched for monophonic or stereophonic sound reproduction. The drive system utilizes an extra compliant belt plus idler wheel to isolate any motor vibration and special shielding of the turntable flywheel, eliminates any induction of stray fields by magnetic pick-up cartridges.
4-speeds plus variable speed adjustment control
12 inch 11,5 pound table with separate non-magnetic aluminun shell cover.
Precision built motor with extra compliant belt-plus-idler isolates motor vibration
Off position completely disengages idler wheel to prevent idler flats
Exclusive Thorens clutch assembly for fast stop and start with no stylus injury
Buil-in illuminated stroboscope enables speed check while record is being played, also acts as pilot light
Built-in level bubble and levelling controls
Replaceable tone arm mounting board for 12 or 16 inch arms
Built-in shock mounts
Exceeds NAB specifications for rumble, wow and flutter
Operates at any voltage from 100/250 volts, 50/60 Hz AC
Thorens TD 124 Transcription Turntable
Highest achievement in turntable design does not mainly result from spectacular new mechanical or electrical elements, but much more from an integration of known, ordinarily conflicting elements, into a new design where best features are magnified and their individual weaknesses eliminated.

As may important features found on Model TD 124 Turntable, including Inertia Controlled Drive and Two Part Turntable with Clutch Action. Professional users and discriminating music lovers will find for the first time so many desirable features harmoniously blended into a new turntable whose basic performance is better than NARTB specifications for broadcasting studio equipment.
Wooden board for tone arm mounting made integral with the cast aluminium frame.
No relative vibrations between base plate and tone arm mounting board; the rumble level is independent of the type of installation.
Easy installation of any type of tone arm; two dimensions of tone  arm mounting board available allow the use of tone arms for 12" or 16" records.
Easy replacement of tone arm mounting board on installed unit when changing the tone arm.

Spring suspension of the whole unit on the mounting board.
Easy installation without the need for additional parts on any base or cabinet; the mounting board does not need to be spring mounted.

Special inbuilt leveling device
The mounting board or cabinet does not need to be leveled
The precision inbuilt water level allows a permanent control of the leveling

Inertia-controlled drive system; relatively light, precision built 4-pole motor, associated to a very heavy turntable
Minimizes the influence of instantaneous voltage fluctuations on the turntable speed; the flywheel, not the motor, is controlling the speed
Keeps motor vibrations very low
Allows a most compliant suspension of the motor on the base plate for maximum damping of any vibration
Keeps the stray flux very low.
 Two steps speed reduction
Between motor and turntable, associating the best features of the belt-driven flywheel and of the stepped pulley-idler wheel speed shift, and eliminating the drawbacks of these two systems taken alone.
The long rubber belt prevents any vibration to be transmitted from the motor to the idler wheel and to the turntable
Extra large diameter aluminium pulley for the belt (1 ¼" and 2 ¾") preventing slipping and deformation of the belt
The rubber belt is easily interchanged from the top of the unit
The stepped pulley for four speed revolves at half the speed of that of conventional systems, thus the steps are of a much larger diameter. Better contact with idler wheel, no slipping and no local deformation of the soft tread of the idler wheel
The stepped pulley is not on the rotor shaft,but has extra long, precision bearing rigidly fixed to the base plate. The vobrations and possible misalignment of the rotor shaft of a spring mounted motor has no effect on the stepped pulley and idler wheel.
Large idler wheel (3 ¼") with permanently bond special tread; no rumble filter action required
Precision control system of the idler wheel for true parallel action with the steady spindles of steeped pulley and turntable.

 Single control knob for the "On-Off" switch and for the 78, 45, 33 and 16 rpm speed shift. "Off" positions between each two speeds.
Variable speed control (+_3%) acting on the four speeds
Precision inbuilt stoboscope for four speed, 60 and 50 cycles
Easy conversion from 50 to 60 cycles operation
Voltage commutator for 100-120, 125-150 and 200-250 volts
