High Pass Crossover. Because your satellite speakers cannot reproduce bass as accurately as the Servo 1200, optimum system performance is attained by rolling off the low end response of your satellites. The Servo 1200 is equipped with a high pass crossover for this purpose. To use the satellites from the Servo 1200's outputs.

USING EXTERNAL CROSSOVER Velodyne offers an optional external LINE IN/OUT but must locate their Servo 1200 away from system electronics. By installing the external crossover near your electronics all leads between your pre-amp and power amp are kept as short as possible quency integrity is thereby maintained while enabling remote subwoofer installation (see Figure 3).

INSTALLATION OF TWO Although a single Servo 1200 will improve the performance of any additional power and effect of stereo Servo 1200s. Figure 4 shows stereo connection using speaker level inputs. Note that one pair of input/output terminals remain unused on each unit. Stereo connections can also be made with the line level inputs.

low frequencies. Even at 1 watt drive levels, many loudspeakers have 8 to 10% THO at 40 Hz. With the 50 watt drive levels needed to produce realistic bass intensity, these distortion figures rise to astonishing levels. Second the distortion products produced by a nonlinear woofer are much easier to hear than is the fundamental fre quency.

Although our HGS electronics play the most important role in reducing distortion, the Servo Series driver must be carefully engineered and constructed so as not to undo the work that the HGS electronics have done.
