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.
