 The Imperial I and Imperial II Speaker Systems.

Before Marantz undertakes to create any high-fidelity component, we must take into consideration a most awesome responsibility; the product must be the finest in the world. That is the tradition of Marantz. Thus we did non step lightly into our task of designing speakers worthy of bearing the Marantz name. The Imperial speakers represent the culmination of a long, hard look at the state of the art. By Marantz audio and acoustical engineers and master interior and furniture designers. Just as important were the professional musicans, thoroughly knowledgeable in the audio field, who inspired, guided, and approved every phase of the creation of this masterpiece. The result - in keeping with the Marantz tradition - is as perfect a speaker system as modern technology will allow. 

Available in two enclosure styles, the Imperial features a three-way design incorporating five speakers: a 12" Quadlinear woofer, a pair of mid-range drivers, and a pair of high-frequency reproducers. The unique Quadlinear woofer has an exclusive fou-magnet design for critical control of  flux distribution in the voice-coil gap. The result is absolutely linear travel of the voice coil, ensuring unmatched transient response and eliminating speaker deterioration. Separate "brilliance" and "presence" controls are built in for acoustical balancing. Hear and compare the marantz Imperial with speaker costing twice as much.  Your ears will convince you that Marantz  long-awaited entry into the speaker field was worth waiting for.

Marantz Model 2

 The Marantz Power  Amplifier has been designed and constructed to give a long, trouble-free life of line listening quality. Here is the type of performance and workmanship that previously was found only in high quality Broadcast or Laboratory equipment. A built-in metered test instrument permits simple, accurate adjustments for optimum performance.

 "The Model 2 power amplifier followed in 1956. largely completed by Sidney Smith, it was a very successful tube design using EL34's in ''ultra-linear'' (push-pull) configuration.

… some sources cite the Model 2 as the beginning of Smith's exclusive concentration on power amplifiers while Saul focoused his attention on preamplifiers,…" (from Marantz History)

 40 Watt / 20 Watt Switch

This unit has been designed primarily as a 40 watt ultralinear amplifier. Speaker systems of a lower power rating could easily be damaged by unwanted pulses coming through at full power. To protect these systems we have incorporated a switch which changes the output connections to Triode operation limiting the power output to 22 or 23 Watts. This control, located near the output terminal strip, is marked '40 Watt UL' and '20 Watt TRI'.

 Input Connections

There is a choice of three input connections to the Marantz Power amplifier.

Pre-Amp: This input is recommended for most preamplifiers. At this connection a 2 volt signal will drive the amplifier to it's full output. A subsonic filter rolls off frequencies below 20 cycles so as to supress speaker "breathing" and other subsonic disturbances.

High Gain, Filtered: For preamplifiers that have a low output voltage capability. Also may be used where loudspeaker has very low efficiency. A signal of 0,7 volts is required here for full 40 watt output. Subsonic filtering is also in effect.

High Gain, Unfiltred: Same as above in sensitivity but without the subsonic filter, response being maintained to below 2 cycles. This input is direct to the input grid and is used in testing frequency response or for special applications where subsonic response is needed.

 Output Connections

When not using Variable Damping:

Use "Ground Return" (center terminal) on loud speaker output terminal strip together with impedance tap on right which matches speaker.

Variable Damping control must be switched off for proper operation.

To use Variable Damping:

Instead of usual ground return, connect to corresponding "Variable Damping Return".

Turn "variable Damping" control on and adjust to desired damping factor.

Specifications

Power Output:  40 Watts ( 80 Watts peak). "Ultra-Linear" operation.

20 Watt Triode Operation. Switch changes output connections to protect speaker of low-power rating.

Pream Input: 2 V RMS into 285 k Ω

Response (has been deliberately rolled off approx. 5 dB at 100 kHz to control transient response):

At 40 Watts : Within 0,1 dB from 20 Hz - 20 kHz, within  1 dB from 15 Hz - 45 kHz

At ½ Watt : ±1 dB from 2 Hz - 50 kHz

Marantz Model 3

 Marantz Electronic Crossover

A considerable improvement in clarity and smoothness of reproduction is obtained when a loudspeaker is connected directly to the amplifier terminals without intervening reactive networks. Th elow internal impedance of the amplifier then tends to dampen spurious speaker resonances. In multi-speaker system it would be necessary to accomplish the crossover at an earlier stage in order to supply separate amplifiers with the frequency range required for each speaker. The Marantz Electronic Crossover was designed for this purpose.

 This new unit embodies typical Marantz quality features. Careful engineering and high grade construction meke this one of the finest instruments of the finest instruments of its type (terminal board wiring, low-noise deposited carbon resistors, precision components, etc.) A basic two-channel unit, it can be cascaded for multi-speaker systems.

Marantz Model 15 (Fifteen)

 The Marantz Model 15 Solid State Stereo Power Amplifier is an instrument without precedend in performance and rugged reliability. As renowned audio authority Julian Hirsch exclaimed, "if any amplifier can be termed ''indestructible''. This is the one." two independant and identical monophonic amplifiers, each with its own power supply, are bracked together and mounted to a handsome gold anodized front panel that matches both the Model 7T preamplifier and Model 10B tuner. Because the channels are completely isolated, you suffer no power loss, "cross-talk', or other interactions that oftentimes occur from simultaneous operation of both channels with only one power supply. The amplifiers are direct-coupled, providing instantaneous recovery from overload and full rated power throughout the full frequency range. At any audio frequency, and on any output impedance from 4 to 16 ohms, the Model 15 is lower than on any other currently available power amplifier. You can use the Model 15 with any loudspeaker on the market, from  a 4 Ω acoustic suspension system to the 16 Ω electrostatic. And, a built-in fool-proof protection circuit gives instantaneous and unobtrusive protection without causing annoying program interruptions.

 All of these features combine to bring you completely reliable operation - year in and year out. The performance of the marantz Model 15 establishes wholly new standards of technical excellence for amplifiers of all types.

 Safety Circuit - A new, current-limiting circuit developed by Marantz protects both output and driver transistors from output short circuits, open circuits, capacitive loads or any type of complex reactive loudspeaker loading. Accidental open - or short-circuiting, even with full-power, 20,000 Hz output is completely safe. Short circuits during operation activate a visual indicator. This unique safety circuit gives instantaneous and unobtrusive protection without causing annoying program interruptions.

Overload Recovery - Instantanous. Clean performance at high peak-clipping levels.

Time Delay Circuit - Loudspeakers are protected agains damage from turn-on "pops" and surges.

 Separate Power Supplies - Channels are completely isolated. No power loss or other interactions from simultaneous operation of both channels.

Crossover Notch - These sharp switching discontinuities have been virtually eliminated in the Maantz Circuit, even at 20,000 Hz. This results in noticeably cleaner performance, especially apparent at normal listening levels.

Front Panel - Matches those of Marantz Model 7T Solid-State Stereo preamplifier Console and Model 10B Stereo FM Tuner in both size and type of finish.

Cabinet or rack mouting available at extra cost

Electronic Time Delay Circuit -  This mutes the signalto the loudspeaker for about five seconds after the unit is turned on, thus elminating the irksome popping noise normally produced at that time by high power supply transistorized units.

Marantz 1030

 The little giant. Little refer to price. Giant refers to quality. Because while the Model 1030 is the least expensive console amplifier Marantz makes - it's still assembled with all the same precision craftsmanship and meticulous construction as the costlier units. It's not quiet as powerful nor does it have as many features.So, what we're really saying is you're not paying extra for extras you don't need. What you do get is 30 Watts or more continuouss power with less than 0,5% distortion. There's a tape monitoring facility and front panel microphone input. The main and remote speakers have convenient quick-connect terminals. Plus, stepped tone controls for easily repeatable settings. The Model 1030 - Thank Marantz for small favors.
