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.

Marantz 5420

  Top loading or front loading. With Dolby or without Dolby. The Marantz stereo cassette deck line has them all. Six decks with design features as exciting as their performance.
The Marantz 5420, for example, keeps wow and flutter down to 0,07%. Plus, it offers a wide frequency response (30 Hz to 17 kHz) and an exceptionally high signal-to-noise ratio (up to 60 dB). All the Marantz decks offer longlife ferrite heads, sophisticated DC servo motor drive systems with total shut-off, tape counters . FET andv IC preamps and the Marantz two-year guarantee on parts and labor.
Marantz stereo cassette tape decks atart at just $269,95. Be sure to see the entire Marantz line including receivers, components and speaker systems at your Marantz Dealer.

 DC Servo Motor for lowest wow and flutter.
heart of the 5420 transport is a DC servo motor - a design that delivers such remarkably reliable speed that the 5420 can claim the incredibly low wow and flutter spec of .07% (WRMS). Here a feedback system corrects for voltage drops, tape drag or other factors that cause speed fluctuation. And a large, balanced heavy duty flywheel connects directly from the motor shaft to transport without the intervening gears that also can affect speed accuracy.
Ferrite heads mean longer life.
At that crucial interface - where tape meets head - the 5420 uses only the best and most durable heads - ferrite. These last up to 200 times longer than standard permalloy heads. They feature precise, even head gap for optimum frequency response and reduced phase shift, and mirror smooth head surface for better tape head contact with minimal tape abrasion and oxide built-up.
Bias/eq adjustments - often an arduous and confusing process of different switching combinations - are simplified by Marantz with 3 clearly-labeled push-switches.  Each pushbutton sets both bias and eq - one for standard ferric-oxide tape, one for chromium dioxide tape and one for ferri-chrome tape.
Built-In adjustable stand that changes the angle of the control panel from flat to 20 degrees.

 Full 4-input mixing console with pan pot and master gain control.
Four inputs - any combination of mic and line -  are operated by four individual slide potentiometers plus one master gain control for fade-in /fade-out. Two pan pot controls permit inputs 3 and 4 to be assigned to either left, center or right stage. Can operate as a separate mixing panel for master quality recordings with external tape recorders.
Built-In Dolby that works with built-in mixing console; permits external Dolby processing an other tape recorders.
Ideal for encoding Dolby on reel-to-reel decks. Functions as a fine external mixer-with Dolby has 25 microseconds deemphasis switch for FM Dolby. Unit can be used with Dolby equipment to achieve dual-process Dolby.
 One button each for Normal,CrO2 and FeCr tapess automatically selects both bias and EQ.
Eliminates confusing, combination adjustments of separate bias and EQ switches Single control calibrates both bias EQ automatically for best frequency response on any cassette tape.
Large VU's plus LED's assure accurate, easy to read recording level control.
Recording levels on the 5420 are measured two ways. Large 3½-inch professional VU meters measure the average loudness of a musical passage, for optimum basic recording level. Then, two LED's indicate peak or transient overloads. Responding far more quickly than VU meters, LED's are ideal for indicating these transients - short, sudden burst of high-level signal that cause severe distortion or even tape saturation.
