NOTE:
• For ordinary speaker systems, we recommend setting the crossover frequency to 80 Hz.
When using small speakers, however, setting the crossover frequency to a high frequency
may improve frequency response for frequencies near the crossover frequency.
Avoid high temperatures.
Allow for sufficient heat dispersion
when installed in a rack.
Handle the power cord carefully.
Hold the plug when unplugging the
cord.
Keep the apparatus free from
moisture, water, and dust.
Unplug the power cord when not
using the apparatus for long
periods of time.
