A NEW CROSSOVER FOR THE QUAD ESL-63 & GRADIENT SW-63
LOUDSPEAKER SYSTEM
The new crossover designed by Gradient is carried out following the best High End principles. The
layout of parts and printed circuits made of high quality components are situated in a solid metal
housing so that both external and internal magnetic and electrical interferences are eliminated.
For instance the power supply is positioned far away from the small signal sections. The components
used have passed the golden ear designer's tests, to mention only Burr-Brown's operational
amplifiers.
Also balanced
The crossover is equipped with both balanced XLR and unbalanced RCA connections to suite
every audio system. Desired type is selected by a switch.
Bass level control
The level of bass can be adjusted continuously by a knob at the rear panel. According to the
personal taste and listening room acoustics the bass is easy to adjust. Once found the correct
balance, there is little need for further adjustments.
Stereo/mono switch
When playing warped LPs the cartridge tone arm system may give rise to high level subsonic
frequencies which cause excessive cone excursion and take a lot of unnecessary power from the
amplifier. Mono operation of bass channel will eliminate this.
Q-value adjustment
Terms fast and slow bass are often used by experts when speaking about the quality of bass
response. The Gradient Research Group studied the problem and solved it. The crossover includes
a three position toggle switch to adjust the Q-value.
