2. Using the included 6’ RCA cable, connect the CHAT 150 VC Breakout Box to both your video conferencing device
and/or TV/monitor, as shown in the following illustration. The cable has two RCA connectors on one end, and five on
the other end, split into two groups with two and three connectors.
The end with two connectors goes to the VC Breakout Box. The blue connector connects to the Audio In port
(identified by the icon), and the black connector goes to the Audio Out port (identified by the icon).
On the other end of the cable, the group with the Red (Right) and White (Left or Mono) connector plugs into the
corresponding audio ports on your TV. This connection allows you to either use the speaker on your CHAT 150 for audio
from the far end, or alternatively you can use the speakers on the TV. See Advanced Settings: Audio Settings in
Chapter 4: Using The CHAT Application for details on using this option.
The group with three connectors goes to your video conferencing device. The Red (Right) and White (Left or Mono)
connectors go to the corresponding Audio Out ports. However, if your video conferencing device does not have left and
right audio out, but only has a single channel (mono), connect the white connector to send a mono audio signal to the
CHAT 150. The black connector is inserted into the Audio In port.
3. Slide the correct power supply clip for your country into the included power supply. The power supply may contain a
plastic shield that must be removed before inserting the clip.

CHATAttach: Connecting Two CHAT Devices
The CHATAttach makes it possible to connect two CHAT devices together for larger conference settings using the
CHATAttach accessory kit.
In order to use the CHATAttach accessory, the following criteria must be met:
Both CHAT devices must be the same model number - both CHAT 150, both CHAT 160 or both CHAT 170 devices -1.
mixing CHAT models using CHATAttach is not currently possible.
Both CHAT devices must have identical firmware versions installed. The firmware must be CHATAttach compatible.2.
To ensure this, download the latest version of the firmware from the Website and configure each device that will
be connected to the CHATAttach accessory with the latest firmware. All older CHAT 150 devices require firmware
updates in order to work with the CHATAttach accessory.
The CHAT device must be at least 5’ apart for best performance.3.
Use the following steps to connect the CHATAttach accessory.
Connect the two CHAT devices using the keyed CHATAttach cable.1.
Position the two CHAT 150 devices so they’re at least 5’ apart from each other.2.
Plug in the CHATAttach power supply.3.
To prevent the power cable from inadvertantly becoming unplugged before, during or after meetings, it
is recommended that the connector end of the cable be secured in some way. One approach is to knot
the male-female connection to prevent this from occurring as shown above.
A recommended professional approach to setting up a conference room utilizing the CHATAttach
accessory is to drill holes near where the CHAT devices will be placed, route the cabling through the
holes and secure them underneath the conference table as shown above.
4. Follow the instructions in the CHAT 150 User’s Manual to setup the CHAT device with a PC.

settings in the CHAT software.
Using with Pre-Defined Device Settings
The pre-defined device settings available in the CHAT application will provide good sound quality for many of the most
popular devices used with the CHAT 150. If you used the procedure in the previous section to configure the CHAT 150’s
settings for one of these devices, test the sound quality before performing any additional tuning. If you are satisfied with
the sound quality, no further adjustments are necessary.
