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.

Meridian MFM tuner


Meridian Modular Tuner the MFM is designed to receive transmission on the VHF-FM band only. The tuner has six pre-settable stations which are selected with a single control knob.
The tuner is designed as a free-standing unit.
Three connections must be made to the tuner, power supply, audio output  (5-pin DIN), and aerial antenna input (unblanced 75 Ω).

Maridian have released ( 1986) an FM tuner, the MFM, to match their Component Amplifier System. Simplicity of operation, neat appearance and excellent sound quality are its main claims to fame. A two-box unit, the tuner uses a sparate mains transformer so it can be used as a "stand alone" item in other systems as well as in situ with its companions in the meridian range. Six preset stations are provided, with tuning via screw-driver-adjusted presets on the RH module. The selected frequency is displayed on a digital readout. 
Price of the MFM is £359

Creek T40 tuner


The idea of an FM only tuner is to receive broadcasts over the air that can be described as having truly hifi performance. Only Frequency Modulation can offer this, so it is therefore not desirable to offer AM in a budget design.
The simple ergonomics of the T40 , the complex control, and advanced radio and audio circuitry within. An advanced digital frequency readout, and display brightness level couple to signal strength make the operation of the tuner as simple as possible, every effort has been made front panel. What is left can be descibed as functional, but it is in the search for the ultimate in the state of the art. Of tuner design which has made this product the bench mark at its price.
martinCollams in hifi Choice (february 1988) described the earlier 3140 model thus "Giving fine results for sensitivity, Signal-to-Noise, pilot tone and AM rejection, selectivity, and capture ratio, the RF side of this fine tuner is beyond reproach". The latest version, renumbered t40 has been further improved and has added facilities, such as variable output level control.
With press and public, acclaim from around the world the T40 has become a modern classic.

Sanyo RD-5350 cassette deck

A front-loading Dolby cassette deck featuring: bias and equalization selectors for "normal", ferrichrome and chrome tapes; two calibrated VU meters; three peak record level indicators calibrated at 0 VU, +3 dB, +6 dB; automatic and of tape stop/disengage; time control through the pause mode that permits a timer-controlled start in the record mode; a record mute that turns off the input signal when the tape is driving in the record mode; a reset counter. The tape mechanism is one of the best we've seen in terms of loading, overall handling, and cleaning of the tape path. It's an excellent front loader for handling by young children.

The Sanyo RD-5350 Dolby cassette deck has one of the most advanced drive motors ever put in a tape machine. It's a new frequency generator DC motor with Phase Locked Loop speed control servo that actually checks and corrects for even the most infinitesimal speed variations 1,247 times every second.
This hair-splitting accuracy helps give the RD5350 one of the lowest  wow and flutter figures in the industry; 0,05% WRMS. And lets the drive system ignore line voltage fluctuations, and breeze right through even "sticky" cassettes without missing a beat.
Naturally, the RD-5350 has one of the most rugged, precision tape transports available today and high performaance electronics. As a result, you get superior specs like 30 -17,000 Hz response (±3 dB, CrO₂ tape) and 64 dB Signal-to-Noise ratio with Dolby. Which is more Hz and less noise than you'll find on the discs and broadcasts you tape.
You also get advanced featres like 3 peak indicating LED's (0, +3, and +6 VU), separate input and output level controls, a Record Mute button for erasing short sections of tape, and a timer standby feature  for taping programs when you're not around.
1,247 times a second this motor checks itself for perfect speed.
How it works - Built into RD-5350 motor is a 68 pole tacho generator that produces a series of pulses proportional  to the motor speed. In the Phase Locked Loop integrated circuit, these pulses are compared with the signal from the precision reference oscillator (1246,7 Hz) if even a singe pulse is found to be slightly out of phase, power to the motor  is adjusted by a econd integrated circuit to restore synchronization. This process takes place independent of fluctuations in load or AC line voltage.
Performance:
The playback frequency response from a standard test tape with a 50 to 10,000 Hz range measured +1,5/-0 dB. Using TDK-AD tape:
Without Dolby, the record/play frequency response measured +0,6/-1,8 dB from 40 to 14,000 Hz, down 2,5 dB at 35 and 15,000 Hz. Distortion at the meter-indicated 0-VU record level was 1,1% T.H.D. with 5 dB headroom to 3% T.H.D. The Signal-to-Noise ratio referenced to 0-VU record level was 49,5 dB.
With the Dolby active, the record/play frequency response measured +1,5/-2,5 dB from 35 to 13,000 Hz. Distortion and headroom remained the same. The Signal-to-Noise ratio referenced to 0-VU record level was 55 dB wideband; 59,5 dB narrowband.
Using Scotch Master III  Ferrichrome tape:
With the Dolby active, the record/play frequency response measured +0/-3 dB from 38 to 15,000 Hz.
Distortion at the meter-indicated 0-VU record level was 1,3% T.H.D. with 5 dB headroom to 3% T.H.D.
The Signal-to-Noise ratio referenced to 0-VU record level was 57 dB wideband; 65 dB narrowband.
Using Scotch Master II Chrome tape:
The record/play frequency response measured +0/-2,5 dB from 35 to 14,000 Hz.
Distortion at the meter-indicated 0-VU record level was 2% T.H.D. with 3 dB headroom to 3% T.H.D.
The Signal-to-Noise ratio referenced to 0-VU record level was 57 dB wideband; 65 dB narrowband.
The maximum output level corresponding to a 0-VU record level was nominally 620 mV
The peak record level indicator calibrations were precisely on the mark at 0-VU, -3 dB, +6 dB.
Wow and Flutter measured 0,09% with peaks to 0,15%

Toshiba PC-5460 cassette deck

The Toshiba PC-5460 cassette deck, with an all-sendust recording head. Dolby FM and Direct Access feather-touch controls
When you buy any of Toshiba's cassette decks, you can take excellent sound for garanted.
Toshibs PC-5460 , for example, has inaudible wow and flutter; just 0,05% WRMS. A high Signal-to-Noise ratio; 69 dB (±3 dB, Dolby On, CrO₂). And wide frequency response 20 - 18,000 Hz (FeCr).
But Toshiba goes beyond specs, to professional features for continued superior performance. Consider the 5460's All-Sendust recording head. It stands up to wear much better than hardened permalloy. And it's noot susceptible to the "chipping" that can occur with ferrite heads.
Then, get your hands on our Direct Access feather-touch controls. The merest touch allows you to switch from one function to another without pressing the Stop button or jamming the tape.
And the Toshiba 5460's front-loading cassette compartment has an oil-damped soft eject mechanism, for smooth and convenient operation.
Of course, almost every cassette deck has Dolby these days. But few have Dolby FM as well. Toshiba does, with a switchable MPX filter circuit. So you can feed Dolby FM broadcasts through the 5460 to get cleaner sound. Whether or not you're recording.

The 5460 tape transport is DC servomotor-controlled.
And you'll appreciate the three-function meter plus LED peak indicator. And our new edit/fade control
Naturally, the 5460 has all the standards as well. Like three-position bias and equalization switches. Mike/line mixing. And circuitry to accommodate an accessory timer.

Pioneer PL-A35 turntable



A fully automatic, belt-driven, professional-quality stereo turntable utilizing two precision motors and complete with induced magnet type cartridge.
The Pioneer PL-A353 is the perfect stereo turntable for the man about to invest in his first set of hi-fi components. But so precise and advanced are its features that an old hi-fi hand will more than feel at home with it. Designed for ease-of-operation as well as precision, the PL-A35 is fully automatic - from the playing of the record to auto-repeat and tonearm return at the end of the record. You'll never touch  the tonearm, your records get extra long-life protection. Additionally, this Pioneer unit features manual operation if you prefer even more precision. It has a double motor system for smooth, stable operation, comes complete with cueing device, anti-skating device, induced magnet type cartridge and diamond stylus. At its price, you'll look a long time to find its equal in performance and reliability. Because Pioneer performance and reliability is not easily duplicated.

Features
Professional performance yet effortless operation
This Pioneer model combines studio-quality performance with the operational ease of a fully automatic. Simply flick the function lever to Start position once, anf the tonearm will be automatically moved over and lowered onto the record and, at the end of the disc, will return automatically to its rest. One-touch Cut and Repeat features let you interrupt and repeat any rcord freely.
Synchronous motor and belt drive
The turntable platter is driven by a synchronous 4-pole motor of excellent stability independent from power voltage fluctuations. The drive belt is precision-finished on both sides, a feature that helpes reduce wow and flutter to an absolute minimum. (The tonearm is moved by a separate, geared motor.)
Anti-skating device
Model PL-A35 features an effective countermeasure against skating (excess pressure of the stylus against the inner wall of the record groove). The anti-skating device keeps the stylus correctly balanced in the groove and assures perfect tracking.
Directly readable tracking force adjustment
The tracking force is adjustable over a wide range so that practically any cartridge (with standard EIA plug) can be accommodated. The balance weight is equipped with a gauge for easy, direct reading of the tracking force.
High quality magnet-type cartridge supplied
The supplied cartridge, Pioneer model PC-50, is a magnetic type of very true-to-the-record sound quality and a frequency response from 10 to 25,000 Hz. Its stylus is a durable diamond type.
"free Hinge" Dust cover
The transparent dust cover is held by spring-loaded hinges and can be arrested in any desired position. If desired, it can be removed altogether.
Oiled walnut base
Adds an extra touch of value and elegance to your stereo installation.

Dual 604 turntable


The Dual 604 is direct drive turntable
You may have noticed that most turntable stories begin and end with the drive system. The tonearm is more or less an afterthought. But not with Dual. Because the tonearm can make a big difference in how records sounds and how long they last. Which is why Dual is very serious about tonearms in our article.
Let's consider the 604 tonearm

The straight-line tubular design provides maximum rigidity with minimum mass. The four-point gimbal centers and pivots the tonearm precisely where the vertical and horizontal axes intersect. And the counter balance houses, two specially-tuned anti-resonance filters that absorb parasitic resonances originating in the tonearm /cartridge system and chassis.
Operation is semi-automatic, with another uniqueDual difference: the machanical sensor. Switch it in and you feel when the stylus is positioned precisely over the 12" and 7" lead-in brooves. At the end of play, the tonearm lifts and returns to its post, and the motor shuts off Automatically.
Now let's talk about the direct-drive system. It employs a newly developed DC electronic motor, with speed regulated by a CMOS integrated circuit and digital reference circuit. Spped accuracy is within 0,001 percent. Wow and flutter are less than 70 dB, as with any great drive system, that's far beyond audibility.
But the important story with any turntable is simply this. The drive system merely turns the record. It's the tonearm that plays it.

Infinity ES-1 headphones



The most acurate headphones ever created. That was the goal.
When Infinity's scientists set out to develop such a stereo component, we determined to start from the highest achievement to date in headphone reproduction - electrostatics - and to remove the previous limitations of electrostatics.
The ES-1 Headphone System demonstrates that accomplishment. And no longer are the finest headphones any less accurate than the finest speakers.
An altogether new diaphragm material is employed in these headphones because it follows dynamic changes much faster and more precisely than the polyester others use. This extremely low-mass material, called Polyurethin, is so responsive as to provide a transient fullness impossible to achieve in the past.
 as a result, Infinity's electrostatic headphones deliver a frequency response of 20 to 25,000 Hz ±2 dB; at a sound pressure level of 100 dB; they show total harmonic distortion of less than 0,3%; their maximum output is a full 118 dB SPL; the realism of their reproduction is startling.
The ES-1 Headphone System consists of one headphone set and the walnut-enclosed adaptor containing power supply and matching transformers. Front-panel output connectors accommodate two headsets; an optional second set is available from your Infinity dealer.
The power supply is to be connected between your amplifier and speakers. Front panel switchingwill let you leave your headphones connected whether you are listening to them or to your speakers. Power supply is also provided with a fast-acting protection circuit to switch off either channel or both in case of overloading that might otherwise damage the unit. A re-set button on the front panel easily puts the circuit back into operation.
Infinity Electrostatic Headphones operate in the push-pull mode, that is, the power amplifier's signal is boosted by the transformer, and constant bias (DC) voltage sets up electrostatic fields which push and pull the diaphragm between two grids.
Infinity coats the Polyurethin of the diaphragms precisely evenly with conductive chemical compounds. The material and the process deliver three benefits:
A high "ratio of extension", the ability to respond to the smallest signal variations and return instantaneously to original tension. Infinity has achieved a marked improvement over polyester, which is 20 times heavier than Polyurethin.
Reduction virtually to zero of the distortion that can be caused when energy is reflected at the suspended edge of a headphone diaphragm.
Voltage spread evenly over the entire diaphragm surface so it will move as a perfect piston with no "hot spots" moving sooner or more than other portions.

As with every Infinity product, the purpose and the result of our using the most advanced technology is to deliver the original, uncolored sound of music exactly as recorded. In the case of the ES-1, you experience a spacious, open quality. Not only can you hear sounds around you (baby's cry, doorbell), but in addition, the music seems to be spread naturally all around you, and not focused unnaturally inside your head.
Your private listening experience with Infinity Electrostatic Headphones will be gratifyingly comfortable, supremely accurate, and totally musical.
