Secure Audio and Microphone 4-Port Switch
OVERVIEW
SECTIONSTable of Contents 1
Features
The Belkin Secure Audio and Microphone Switch was designed with
the user in mind for today’s VoIP environments. Below is a summary
of some features incorporated into the Switch.
Dedicated Boards
The Switch features a dedicated printed circuit board for audio and
microphone signals. This keeps the audio signals physically separated
from the microphone signals to reduce the possibility of leakage
between both signals.
No Memory Buffer
The Switch does not have a memory buffer and does not have the
ability to store data. This prevents any keystrokes or other data
input from being unintentionally transferred as you switch between
computers, ensuring the integrity of your data.
Non-Reprogrammable Firmware
The Switch features custom firmware that is not reprogrammable,
preventing the ability to tamper with the Switch logic.
Metal-Plate Firewall
A metal firewall is placed between the audio and microphone PCBs
(printed circuit boards) to reduce the potential of EMI (electromagnetic
interference) leakage.
Tamper-Evident Tape
A holographic security tamper-evident label is placed on the
enclosure to provide a visual indication if the Switch has been opened
or compromised.
Secure Packaging
“Tear away” packaging ensures secure delivery of the Switch as it is
routed to the end user.
Audio and Microphone Switching
The Switch supports both stereo audio and microphone analog
signals. Analog signals are passed through. This allows you to share
headsets, speakers and microphones between computers or
IP phones.
Microphone-Mute Button
The Switch incorporates a microphone-mute button to shut-off the
microphone when the Switch is not in use or while handling calls
where the microphone is not required.
Port Coloring
The included color chips can be inserted into each port-selector
button. Colors can be associated with an established network to
facilitate port identification and reduce user switching error.

Pre-Configuration
Where to place the Switch:
The enclosure of the Switch is designed for desktop configuration.
Consider the following when deciding where to place the Switch:
• your proximity to the port selectors on the front of the Switch
• the lengths of the cables you use to connect your computers/phones
to the Switch
Connection and Installation
Step 1 Connecting the Console to the Switch
Connect your headset, speaker, and microphone to the rear of the
Switch in the “Console” section. (Refer to diagram on page 6.)
Step 2 Power Up
Power up the Switch by connecting the power. The LED for Port 1
should light up solid white a second after power up.
Step 3 Connecting Computers to the Switch
Using the Belkin Shielded Audio/Mic Cable Kit, connect the computers
to a port on the rear of the Switch. Other devices may be connected
with appropriate adapter cables. (Refer to diagram on page 6.)

OPERATING THE AUDIO AND MICROPHONE SWITCH
SECTIONSTable of Contents 12345
Operation
Selecting a Computer Using Port Selectors
Now that you have connected your console and computers to the
Switch, it is ready for use. You can select which computer you wish
to direct audio to by pressing the corresponding port selector on the
front of the Switch. The LED next to the port number will illuminate
to indicate which computer (or port) is currently selected. You may
hear a clicking sound after each switch. This is normal behavior and
indicates a mechanical connection has taken place.
Using the Microphone-Mute Button
The Switch offers a microphone-mute button to shut-off the
microphone when the Switch is not in use or while handling calls
where the microphone is not required.
Enable the microphone mute by selecting the microphone-mute
button. After it is selected, the microphone will be muted and the
microphone-mute LED and current selected port will light up red.
Note only the microphone will be muted. Audio signals will still pass
through uninterrupted.
Attention!
Please note that the default port at power-up is Port 1. In case
of a power failure or if the power is cycled, the Switch will
default to Port 1.
