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.

12 crossover points at ½ octave intervals. Adjustable from 100 cps to 7000cps. Separate switch and a balance control for each channel.

12 dB per octave rolloffs with -3dB (non-ringing) "knees". 12 dB down one octave beyond crossover.

Self-powered by remote supply. All 3 dual triode tubes provided with filtered DC on filaments for elimination of Hum problems.

IM Distortion:  2 volts equivalent RMS; less than 0,1%.  15 volts equivalent RMS; less than 1%

Noise:  better than -90 dB below 2 V output

10 dB gain available with balance controls at max.  Normal (Zero dB gain) position indicated.

Cathode follower outputs.

Optional: Dual or Single cabinet in mahogony, walnut or blonde wood.
