40W Power Amplifier speakers). COM is for grounding (GND). System Connection Usage Precautions 1) No working with empty load is allowed. 2) Speakers must be connected before power on. System Diagram Figure 3 System Diagram Audio Signal Connection Audio Output PA3V 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.
40W Power Amplifier Figure 4 Audio Output Connection Audio Inputs PA3V provides with 2 stereo audio inputs, one microphone input and one digital fiber audio input. The following figure shows the audio input ports. Dial Switch, to select the MIC input mode, includes MIC (dynamic microphone), 48V (condenser microphone) and LINE (normal audio or wireless microphone).
40W Power Amplifier “-” 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.
40W Power Amplifier Volume/EQ controlling The line volume and MIC volume can be controlled by the buttons. The MIC Volume/LINE volume/LINE bass/LINE treble will be selected by the buttons, and controlled up/down/mute by the function buttons.
40W Power Amplifier IR receiver, works together with the IR remote. Please point the IR remote at the IR receiver when use, to avoid getting out of control as there is no signal detected. 3.5mm jack Insert it into the specialized PA3 socket (3.5mm), to connect the IR receiver with PA3. Figure 9 IR Receiver Operations of Control Software Connection with Computer When the amplifier connects to the COM1 or COM2 of the computer with control software, users can control it by that computer.
40W Power Amplifier Running Environment While the control software is installed, we can activate the software through the RS232 port and set the parameters, to make it able to send RS232 commands to control PA3V. Function Settings With the control software, we can easily switch the input channel, mute the output, check the working status, and adjust the volume etc. Please refer the details in RS232 Communication Commands.

40W Power Amplifier Panel Drawing Figure 13 Panel Drawing Troubleshooting and Maintenance 1) When there is no output audio: Check if there is any signal at the input. Check if there is any signal at the output. We can check these by using an oscilloscope or a multimeter. If there is no signal input/output, maybe the input/output cables broken or the connectors loosen, please change for another cable. Check if the output port number is the same with the controlled one.
40W Power Amplifier Safety Operation Guide In order to guarantee the reliable operation of the equipments and safety of the staff, please abide by the following proceeding in installation, using and maintenance: 1) The system must be earthed properly. Please do not use two blades plugs and ensure the alternating power supply ranged from 100v to 240v and from 50Hz to 60Hz. 2) Do not put the switcher in a place of too hot or too cold.
