Computer Control
Connection
The BG-A1616MD audio processor can be controlled via the provided software on a
Windows 7/10/11 machine. Use a category cable to directly connect to the LAN port of the
processor to your computer or via your local network using the following steps.
Step 1: Install the
“BZBGEARAudioMatrix16.exe” application
on the host computer and change the
computer’s IP address to ensure that IP
addresses of the host computer and the processor (Default IP address: 192.168.0.199,
Subnet mask: 255.255.255.0) are within the same network segment, as shown in the figure
below.
Step 2: Double-click the “BZBGEARAudioMatrix16.exe” icon to run the application on the
host computer.
Step 3: When the application is opened the HOME page will appear as shown below.
Step 4: Click the Network icon on the toolbar at the top .
If there is a red X at the top-right corner of the icon as shown in the figure above, it means
the host computer has not connected with the audio processor.

BZBGEAR BG-A1616MD PRODUCT MANUAL
In such a case, click the icon and a dialog box with a list of IP addresses of all connected
devices will pop up, as seen in the following image.
Step 5: Choose the audio processor’s IP address and click CONNECT, then the processor
will be connected with the host computer. After connection, the CONNECT & SETUP box
(see the figure below) will pop up. You may close it if no such operation is needed.
If the audio processor has been connected with the host computer successfully, the
Network icon will appear as shown below with a green check in the top right corner.
Volume Meter
The volume meters will display the signal level of the various input & output volumes.
The meter has 3 colors (Red, Yellow, and Green) to denote signal levels for the volume
of the 16 inputs and 16 outputs. Red means that volume may be too high to be limited,
yellow indicates the volume is ideal, while green is within a reasonable lower range.

Input Settings
As shown below, clicking the INPUT module on the HOME page or the “IN” tab on
the menu bar will open the INPUT setting page.
The following figure shows the details of the INPUT setting page.
GAIN CONTROL: Indicates the GAIN level of the input signal which can be adjusted.
INVERT: Inverts the polarity of the signal on the input channel.
PHANTOM: Turns on 48V phantom power for the channel.
MUTE: Mutes the input channel, equivalent to clicking the letter M on the INPUT module
on the HOME page.
WHITE: Generates white noise for signal testing.
PINK: Generates pink noise for signal testing.
SINE: Generates a sinusoidal signal for testing and the meter below shows the frequency of
the sine wave.
FADER: Controls the signal level of the test signal.
You can set the signal parameters of an input channel by entering its “CHAN” number in the
menu on the right of the “IN” page. Audio process modules such as EXPANDER,
EQUALIZER, COMPRESSOR and AUTO GAIN CONTROL, are also available in the right
panel.
