It lights up when the speaker output level becomes around - 46 dB or more of the rated
output.
It may not light up when the output level is low. It is not malfunction. Blinks when muted.
(Muting function is done only by IR IN or RS232. This unit does not have this operation.)
PEAK indicator
Lights up when the speaker output level reaches its peak (around - 3 dB from the rated
output).
If it lights continuously, the sound maybe distorted. Lower the volume if necessary.
⑥ BASS / TREBLE
You can adjust BASS (low frequency) and TREBLE (high frequency) from -10 dB to +10 dB.
Use a small screwdriver, etc. .
⑦ Master Volume
Adjust the output level to the speaker and PRE OUT jack. Turning it to the right will increase
the volume. If you add PCA1120, you can raise or lower the system volume by this knob.

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.

Operation
■ MIC 1 Connection
No-voltage contact
Short-circuit current: 3 mA or less
Open circuit voltage: DC 24 V or less
Microphone with contact
・ Mic Ducker and Feedback Suppressor can be used with either MIC 1/2.
・ Connect the microphone with paging function to MIC 1, and wireless microphone to MIC 2.
・ Since there is no phantom power, use battery-powered condenser microphone.
・ Normal dynamic microphone can be used with either MIC 1/2 Input.
Microphone
Microphone
Short the terminals
between [C] and [E]
■ MIC 2 Connection
1. Set #6 [ SET UP ] DIP Switch [ MIC 2 / LINE 3 ] to [ MIC 2 ].
2. Use #7 [ SET UP ] DIP Switch [ MIC2 AMP ] to select between
[ On ] (Mic level) or [ Off ] (Line Level).
If using a wireless MIC, this selection should be based off of the output level of
the microphone receiver unit.
3. Connect the output of the microphone to the MIC 2 terminal with Euroblock.
For the connection method of the shielded wire, refer to the section on MIC 1 Connection.

Step 4 ： Connecting Microphones
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.
・ If the volume is low even if the other input volume is maximized in step 4, lower the input
volume in step 1 slightly and repeat from step 2.
Step 7 : Adjusting Volume

Since some parts such as cooling fans are consumable parts, it is necessary
to replace the parts according to deterioration.
