2) SETTING THE CROSSOVER POINTS FOR THE REAR (MIDRANGE) OUTPUT
Usually the MID output is a BAND PASS design. It’s achieved by setting the MODE switch at
“BP” and using both HIGH PASS and LOW PASS FREQUENCY dials. Set the desired HIGH
PASS frequency anywhere between 40Hz and 1KHz for the low frequency cutoff, and set the
desired LOW PASS frequency anywhere between 1KHz and 12KHz for the high frequency
cutoff.
Selecting HIGH PASS from the MODE switch and using HIGH PASS FREQUENCY dial alone
will remove the high cut off section and allow the midrange output to play up to 20KHz.
Selecting ALL from the MODE switch. This setting will be ideal if you’re using ALL range
speakers capable of reproducing Full frequencies.
3) SETTING THE CROSSOVER POINT FOR THE FRONT (HIGH) OUTPUT
Set the desired frequency cutoff point using the HIGH PASS FREQUENCY dial for your HIGH
output such as Tweeters and/or Compression Drivers. The frequency range for this pair of
channels is 1KHz to 12KHz.
