Quality Standards
Wahsega products achieve the highest standards of performance in
the market by utilizing our complete quality assurance program
encompassing software testing, product design and a multistage
automated factory test program.
Wahsega’s ultimate goal is to provide a solution that is both cost
effective and unsurpassed in quality. By leveraging existing
relationships with suppliers to guarantee premium components at the
lowest possible prices, we are able to ensure Wahsega products are the
finest quality in the market while still offered at highly competitive
prices directly to installers.
In order to achieve the greatest possible voice clarity, all voice and
related algorithms have been individually tested to ensure the highest
potential MOS score. The accumulated error syndrome, which can
cause poor voice quality, is mitigated through this testing process.
Wahsega’s engineering team utilizes a wide array of dedicated test
servers to pull and build the various software projects multiple times
per day. Each automatic build is then run through an extensive set of
automated test cases to ensure the highest performance of each and
every firmware version released. This test case coverage is expanded
on a continual basis.
All Wahsega products are 100% factory tested at the board level
through a bed of nails full functional test, not just an “is it close
enough?” flying probe test. Every finished product is 100% tested again
after the final assembly via an automated test station to ensure the
highest production quality product for installers.
To assure the highest quality standards, all Wahsega products are
designed, developed and manufactured in the USA.

Chapter 2
User Experience
The Carina 2x2 Ceiling IP Speaker receives and plays audio broadcasts
from the Carina Event Manager via multicast and can also place and
answer two-way SIP calls using an IP PBX such as Wahsega’s Paging
Intercom Server (PICS).
The Carina 2x2 Ceiling IP Speaker works with standard call buttons or the
Wahsega Call Button. Advanced functionality can reduce the number of
false alarms from that call button. A brief button press places a SIP call to
one preconfigured number—such as the front office—while a longer
press-and-hold will call a second number, such as a security desk.
An optional room sound reinforcement panel allows users to play audio
from a local source such as a computer or smartphone. Incoming
broadcasts and calls mute the local audio, making sure users never miss
an alert or announcement.
The Carina 2x2 Ceiling IP Speaker has the ability to drive a second,
independent and lower-cost Wahsega speaker up to 20 meters away via
Cat5e or Cat6 cable. For larger classrooms where a second speaker is
needed, the Wahsega Extension Speaker (WL-SPKR-xx-A) can be used to
increase audio coverage without a second PoE homerun. Alternately, the
Carina 2x2 IP Ceiling Speaker can be used in conjunction with the
Wahsega Second Room Speaker (WL-SPKR-xx-2R) for independent control
of two separate rooms, using only one PoE port and cable homerun.
The Carina Event Manager automatically discovers and registers the
Carina 2x2 Ceiling IP Speaker at startup, and all programming and
configuration can be handled individually or in bulk through the Carina
Event Manager dashboard. This greatly simplifies the installation process
and makes it easy to manage the system once installed.
With simple installation and advanced functionality, the Carina 2x2 Ceiling
IP Speaker is perfect for education, healthcare, industrial and commercial
deployments.
Carina 2x2 Ceiling IP Speaker User’s Guide Page 8 v 3.0.1.20200827
Software Capabilities
Wahsega’s Carina IP Speaker is configured centrally at the Carina Event
Manager, which allows bulk configuration as well as individual
customization. This allows access to various settings such as network/IP
address, SIP account and Event Manager configuration, intercom/speaker
and display behavior, panic button call numbers, and administrative
functions such as firmware upgrade and configuration backup/restore.
The configuration is stored in a .JSON file, which is human readable and
can be edited by site administrators.
The Carina IP Speaker configuration is also accessible using an HTTP
Web interface, viewable from any Web browser on the same LAN.
However, all Carina devices should be configured within the Carina
Event Manager’s configuration webpages whenever possible. Any
configuration changes to the IP Display’s individual webpages will be
overwritten by the Event Manager.
Carina 2x2 Ceiling IP Speaker User’s Guide Page 9 v 3.0.1.20200827
Getting Started
1. All Carina devices should be configured within the Carina Event
Manager’s configuration webpages. While it is possible to make
changes at the device’s own webpages, any configuration changes to
the device’s webpages will be overwritten by the Event Manager.
2. Locate and note your Carina IP Speaker’s MAC address. It is printed on
a white sticker located on the rear of the device.
3. Connect the Carina IP Speaker’s main Ethernet port—labeled LAN—to a
network using a Power-over-Ethernet (PoE) Ethernet connection. When
connected, it will power on immediately, and the LINK/ACTV status LED
will begin to blink.
4. Your Carina Event Manager will automatically detect the Carina IP
Speaker when you power up and connect to the network via PoE.
5. On the Event Manager’s Web interface, navigate to the Devices page to
discover your Carina 2x2 Ceiling IP Speaker’s IP address. Look for the
device matching the MAC address you just noted.
6. Following the instructions in the next sections, change Event Manager
settings for your Carina IP Speaker as needed.
7. To apply changes and settings to your Carina IP Speaker, save changes
and reprovision your speaker. This is an important step! Your changes
in Event Manager will not take effect until you have reprovisioned the
endpoint.
Carina 2x2 Ceiling IP Speaker User’s Guide Page 10 v 3.0.1.20200827
Endpoint Configuration
Without Carina Event Manager
If needed, individual endpoint configuration is available via the Carina 2x2
Ceiling IP Speaker’s individual webpages. However, if users choose to
make configuration changes in the speaker’s webpages, those
changes will not be recognized by the Event Manager and will be
overwritten by any configuration changes made to the endpoint in the
Event Manager. For best results, all configuration changes should be
made at the Event Manager and not at the speaker’s individual
configuration webpage.
1. To access an individual speaker’s webpages, navigate to its IP
address in your Web browser (for example, http://123.456.78.9).
Wahsega recommends using Chrome or Firefox for best results.
2. When you access the configuration webpages, the speaker will ask
for a username and password. The default username and password
are admin and admin.
3. On the left side of the page is the Status bar. It shows the speaker’s
current System information such IP address, MAC address, system
time and uptime. The speaker’s SIP account status (default status is
unconfigured and unregistered) is listed under Accounts.
Carina 2x2 Ceiling IP Speaker User’s Guide Page 11 v 3.0.1.20200827
4. To change the IP address settings, go to the Network page and
modify settings in the WAN section. To set the network for DHCP,
click the Dynamic IP radio button. For static IP addressing, click the
Static IP radio button and fill in the relevant IP address fields with
values from your network administrator.
5. Set time and date and change username or password on the System
page. Please note that the Carina Event Manager may be used as a
system NTP server for consistent date and time across the network.
Simply enter carina.wahsega.local as the NTP server and make sure
that NTP is enabled for this endpoint.
6. To change the SIP account settings, go to the Accounts page and
modify settings in the account. Most users will only need to set
Username/Number (the phone number or extension assigned to this
speaker), Domain (the hostname or IP address of your SIP server)
and Password (password for this SIP extension, if needed). You may
also provide a Display Name, which may be used by your SIP server
depending on its configuration.
If your SIP server or proxy server requires an authentication
username that is different from the name entered in
Username/Number, enter it under the Authentication Username field.
7. Load new firmware, backup configuration, or restore a configuration
file on the Management page.
Carina 2x2 Ceiling IP Speaker User’s Guide Page 12 v 3.0.1.20200827
Chapter 3
Configuration in Event Manager
The Carina 2x2 Ceiling IP Speaker should be configured within the

Appendix A
Restoring Factory Settings
Software-based Factory Reset
If you need to erase the configuration settings in your Carina 2x2 Ceiling IP
Speaker, you can do so in one of two ways. Option A returns only IP
settings to factory default, and Option B returns all of the speaker’s
settings to factory default.
Reset Button
Status LED
Figure 1
Carina 2x2 Ceiling IP Speaker User’s Guide Page 29 v 3.0.1.20200827
Option A – Steps for activating a partial factory reset:
1. Start with the PoE cable plugged in and the speaker powered on.
2. Find the green status LED on the face of the speaker. Next to the
status LED, locate the small, black reset button.
3. Press and hold the reset button until the status LED begins to blink.
(If the status light does not begin to blink, reposition and try again.)
4. Once the status light begins to blink, release the button, and the LED
should return to a solid green.
5. You have successfully reset your ceiling speaker’s IP address to its
default DHCP address. You will need to use this new, dynamic IP
address to access your speaker’s configuration webpages again.
Option B – Steps for activating a full factory reset:
1. Start with the PoE cable unplugged and the speaker powered off.
2. Plug in the PoE cable and apply power to your ceiling speaker. As
soon as power is applied, hold the reset button as the status light
begins to blink.
3. Once the status light starts to blink, continue to hold the button for
at least five (5) seconds.
4. After 5 seconds, the status light will flash more slowly, indicating that
the file system has been reformatted and all data has been erased
from the device.
5. Unplug and restart your speaker for the new settings to take effect.
6. If you have previously changed the IP address of your ceiling speaker
to a static IP address, keep in mind that restoring factory default
settings will return your speaker to dynamic IP (DHCP) mode. You
will need to use the new, dynamic IP address to gain access to your
speaker’s configuration webpages once again.
7. You have successfully reset your configuration!
