3.3 Audio Signal Connection

3.3.1 Audio Output

PA100V supports mono audio output, and the output voltage is 70V or 100V. The end COM is for grounding. The amplifier to be connected is mono audio output with a rated power at 40Watt, so PA100V can be connected with several speakers in parallel connection (Total power mustn't be more than 40Watt).

The following figure shows us how to connect the speakers. Here we take the 100V/10W speakers as an example.

Note: Speakers to be connected should be with constant pressure.

3.3.2 Audio Inputs

PA100V 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).

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.

> 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

PA100V has 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.

Notice: This digital audio input can support/decode PCM format signal only. If the CD/DVD is DTS or AC3 format, please set the player to PCM format output before connecting to PA100V.

3.4 System Applications

PA100V can be applied in different occasions, such as classroom, small meeting room, lecture hall, bar and hotel etc.

4. System Operations

4.3 Operations of Control Software

4.3.1 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.

To control the amplifier, users should use a 3-pole male captive screw to 9-pin HD female connector and use the public COM software.

Figure 10 Connection of RS232 Port

4.3.2 Installation/uninstallation of RS232 Control Software

- Installation

Connect the input source devices and the output device according to the system diagram.
➢ Copy the RS232 control software to one computer, and then connect the RS232 port of this computer and PA100V.
Double-click the EXE program to execute the software.

Here we take the software CommWatch.exe as example. The icon is showed as below:

CommWatch.exe

Figure 11 Control Software

- Uninstallation Delete all the control software files in corresponding file path.

4.3.3 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 PA100V.

4.3.4 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.

The interface of the control software is showed as below:

Notice:

1. The letter inside bracket [] is the variable code, which is changeable.

2. The bracket [] is not included to the RS232 commands.

3. Any dot “.” after the letters is part of the commands.

4. Ducking function:

When input with MIC, the volume of the line audio will be automatically turned down to the preset volume level, if there is no input MIC audio signal after 5 seconds, then the volume will be automatically turned up to the original one. If you need to disable/enable the ducking function, just send the command "610%" again.

5. ID coding

The ID codes of PA100V ranges from 0 to F (hexadecimal), when sending RS232 commands, please take notice of the address of the ID code.

If the address of the ID code is 0, any RS232 command is available.

If the address is in 1\~F, it has one unique ID code (If the ID code is not the same with the address, no RS232 command will work).

While the ID code is in 1\~F, please add "ID/" before sending the command.

For example, if the ID code is 5, the RS232 command needed is "604%", the correct command is in this format: 5/604%.

There is no need to add "ID/" before the command when the ID code is 0.

Examples:

1) Switching the input 2 to the line out, the command is: 2A1.
2) Turning up the volume of line audio, the command is: 603%
3) Preset the MIC volume to "21" degree, the command is: 521%
4) Checking the working status of PA100V, the command is: 600%
5) If the ID code is 0, sending command 601% is able to turn up the MIC volume. If the ID code is 2, sending command 601% will not work, and the MIC volume remains unchanged. The right command is 2/601%.
