Description of Controls

Description of controls
The unit features a comprehensive set of controls to tune the performance of each speaker according to the
conditions of use. The response may be shaped by a combination of three parametric equalisers, each having
a level range of +4.5 / -12 dB, and low- and high-frequency contour controls, the effects of which are illustrated
in figure 19. In addition, level controls are provided to compensate for any differences in gain between both the
subwoofer and LF power amplifiers compared to the MF/HF power amplifier.
To access the front of the unit, pull off the decorative facing plate.
