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.

Elac Miracord 50H mkII turntable

At first glance, most automatic changers seem pretty much the same. A record drops, the turntable spins, a tone arm moves over to the record, where a stylus ( or needle) drops into the grooves. This sets off a chain of electronic impulses that ends up as music from your speakers. Any automatic changer will do all this.

An Elac Miracord will do it better. Every step of the way. Result; a fuller, richer sound from your records. In very simple terms, here's how we do it:

Start with the Elac tone arm. Its job is to hold the cartridge (which holds the stylus) and swing out onto the record. Most tone arms will do just that. The ones we build do just a litle more.

 to begin with, there's the tracking force. This is technical talk for the amount of pressure the tone arm brings down on your records. Naturally, the lighter the pressure, the lower the friction - and the more plays you'll get from each record and each stylus. That's why at  the base of the Elac tone arm you'll find a special little knob that lets you adjust the weight coming down on your records to less than one gram - or one twenty-eight of an ounce.

How many times have you tried to play a specific cut on an LP and dropped the tone arm either past the beginning of the tune either past the beginning of the tune you want, or into the ending of the song before it.

 

That can be hard on your ears, and even harder on your records. That's why we've come up with a cueing device so foolproof you can literally pick any groove on a record and ease the needle into it. Just flip a lever which gently raises the tone arm and lets it float with the stylus a hair's breadth over the record. Position the arm exactly where you want it, and flip the lever back. This operates a cleverly-designed, tiny piston which softly lowers the needle into the gtoove you've selected.

Which brings us to yet another example of Elac wizardry. The natural inclination for a needle on a record is to wear against the inside wall of each groove, (if you've ever heard a stereo record where the separation seems poor or the sound is distorted, this could well be the cause), Elac eliminates this inward drag with a special anti-skate device.

All Elac changers have push-button controls, positioned where they;re easiest to reach.

Everything is controlled by push-buttons, including the heavy-duty motor. Bearings are precision-made so you can forget about the annoyance of rumble and flutter. And life-time lubricants help keep maintenance to the barest minimum.

Everything we've mentioned so far is on every Elac Miracord. An impressive set of credits, to be sure. For some models, however like the 50H mkII its just the beginning.

 

Quite simply, the best automatic turntable money will buy. The 50H mkII contains a set of advantages that places it beyond the reach of any other charger in the world. With the variable speed control you can set the speed at precisely 33-⅓ or precisely 45 rpm, and a stroboscopic ring on the turntable will read out the accuracy of the speed. You may vary the speed by as much as three per cent either way. This not only assures you of exact control for normal listening, but also comes in handy for special uses such as dubbing sound home movies, or playing along with a musical instrument, where precise pitch is essential.

The 50H mkII is also a rarity in that you can now play your finest records and the precision arm will be lowered by the silicon damped cueing device, even in the automatic phase. A newly developed synchronous hysteresis motor reduces rumble to  an all-time low while maintaining a speed accuracy that is truly incredible. All told, the Elac Miracord 50H mkII represents the ultimate in automatic changers but to fully appreciate everything it offers you've really got to hear it for yourself.
