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:

• 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
