In most installations, the user merely loads crossover settings from the supplied speaker library, and then adjusts
the output trims as required to compensate for amplifier gain differences and speaker efficiency differences.

Figure 5.2c Crossover Overview
In the lower portion of Figure 5.2c, the LFE band is shown. It is not really a crossover since it does not split the
channel into multiple frequency bands. It is similar to a crossover, however, in that a single audio channel is split
into multiple outputs with separate equalization (parametric) and delay. Because of this similarity, the LFE
equalizer is located in the crossover section of the DSP. The additional LFE2 output is only available from the
crossover board’s output connector.

Model Numbers
An optional output board is part of the unit’s assembly that supports a variety of output configurations. Available
output configurations include 8 analog outputs full range and biamp (3 stage crossover channels).
The various JSD-60 options are identified by model number suffixes as shown in the tables below. The first letter
identifies input options such as the presence or absence of Dolby Digital ® and DTS® ® decoding. The second letter
indicates the type of output. Note that all units have analog HI/VI-N in addition to the outputs listed in the tables
below.
A JSD-60DX has 8 AES/EBU input channels, Dolby Digital® and DTS® decoding for alternative content with biamp
analog outputs.
