  When the ducker senses audio from MIC 1 and/or MIC 2(not LINE 3), the volume of all other input
  sources will be attenuated by 24dB. This is useful for paging over background music.
  If you set #6 [ MIC 2 / LINE 3 ] of SET UP DIP switch to [ MIC 2 ], you can use this function with
  two microphones.

Benefits of combining MCA1120 with one or more PCA1120(s).
 a. Additional speaker zones can be added (See Example B).
 b. A passive subwoofer can be added to the system (See Example C).
 c. Both the MCA1120 and PCA1120 include independent Preset EQ and HPF, allowing you to
   tailor the sound of each speaker area.
 d. The MCA1120 Master Volume control can be used to adjust overall system volume for
   all areas since its PRE OUT terminal is variable. In this application, set the PCA1120 volume
   control to the center position (12 o’clock). Alternatively, you can adjust each PCA1120
   volume independently.

1. Set the Input Volume to the position of the center (12 o'clock) connected
to the external source device used by the main .
2. Keep the other input volumes to a minimum.
3. Play back the BGM and adjust the master volume to the optimum volume.
4. With the master volume decided in step 3 fixed, while outputting sound
from other devices and microphones, gradually raise each input volume to
balance the volume.

Installing your amplifier
Do not block any ventilation openings.
By playing your equipment at higher level for a long period, the protection circuit maybe activated by
