3.3 Audio Signal Connection
3.3.1 Audio Output
AP3DBL supports mono audio output, and the output voltage is 70V or alterative 100V. With its dual-purpose design, it can be
applied in different areas. The end COM is for grounding. The amplifier to be connected is mono audio output with a rated power at
40Watt, so AP3DBL can be connected with several speakers in parallel connection way (Total power mustn’t be more than 40Watt).
The following figure shows us how to connect with the speakers. Here we take the speakers 10Watt@8Ohms for each as example.

3.3.2 Audio Inputs
AP3DBL provides with 2 stereo audio inputs, one microphone input and one digital fiber audio input. The following figure shows the
audio input ports.
Figure 5 Audio Input Ports
48V phantom power input
When the switch turns to “48V” (It has a good frequency characteristic, high input impedance and high sensitivity in this mode), the
MIC input will provide a 48V phantom power. This is usually used for power supply for condenser microphone, Connection is: “+”
connects to positive, “-” connects to negative and “ ” to ground.
Note: In this mode, only condenser microphone can be connected with.
MIC input
When the switch turns to “MIC” (It has a low frequency characteristics, and wide frequency response in this mode), the microphone
input is used for connecting with dynamic microphone. There are two different connections:
a) Unbalanced connection:
“+” and “ ” connect to ground, and “-” connects to signal.
“-” and “ ” connect to ground, and “+” connects to signal.
b) Balanced connection: “+” connects to positive, “-” connects to negative and “ ” connects to ground.
LINE input
When the switch turns to “LINE” (It has a low frequency characteristics, and wide frequency response in this mode), the microphone
input is used for connecting with normal audio or wireless microphone output. There are two different connections:
a) Unbalanced connection:
“+” and “ ” connect to ground, and “-” connects to signal.
“-” and “ ” connect to ground, and “+” connects to signal.
b) Balanced connection: “+” connects to positive, “-” connects to negative and “ ” connects to ground.
Digital Audio Input
AP3DBL provides with a fiber optical port to connect with digital audio source device. With the SPF optical fiber, the audio signal can
be transmitted faster, more stable, reliable, and can be transmitted over a long distance without distortion.
3.4 System Applications
AP3DBL can be applied in different occasions, such as classroom, small meeting room, lecture hall, bar and hotel etc.
