CD horn EQ
If you need equalization for a constant-directivity horn, set a jumper on
J203 for the amount of boost you need. If you do not want CD horn equalization, do not
place any jumper on J203.

Ultrasonic filtering
If you need ultrasonic filtering, set a jumper on J201 across pins 2 and 3
to enable Channel 2s Low-pass filter and insert a resistor network into RN202 that
corresponds to the desired roll-off frequency. If you do not want any ultrasonic filtering,
set the jumper on J201 across pins 1 and 2 to bypass the low-pass filter.
