2. Connecting AudioFetch to Audio Sources
Connect an audio source to one of the 3 input options. CHOOSE ONLY ONE INPUT
CONNECTION. Two popular analog connections are RCA (one red and one white) and a
3.5mm stereo jack (headphone jack). Either one can be connected into the Analog input of
AudioFetch which is a 3.5mm stereo jack. Digital connection options are optical and digital
coax.
Note that RCA and digital coax connections are not the same. A digital coax output (on TV,
etc.) cannot connect into the AudioFetch Express analog input. An RCA analog output (from
TV, etc.) cannot connect into the AudioFetch Express digital coax input. The configuration
management pages can be logged into as described below to determine if a good audio
signal is connected into the channel. When connecting via digital inputs, always choose the
audio source type (in the TV or STB menu) as PCM since Dolby Digital encoded signals are
not supported.

5. Configuration Management –“The Doghouse”
Most applications do not require access the Doghouse Configuration Management
tool since the default settings are adequate. Configuration settings can be viewed
using a web browser on a device (PC, Tablet, mobile phone etc.) that is connected to
the same pre-existing network as AudioFetch Express (when operating in Client
Mode) or connected to the AudioFetchExpress Wi-Fi network (when operating in
Access Point mode).
First, ensure your device is connected to the same network as AudioFetch Express.
Option to use Doghouse on a Windows device: Run the Doghouse Utility found
at www.audiofetch.com/doghouse to locate AudioFetch on the network. Once the
AudioFetch box is displayed, click the “Connect” button to open the starting
configuration page on a browser.
Option to use Doghouse on Android or Apple devices: Search and download
“AudioFetch Doghouse” in the Google Play®(Android OS devices) or Apple iTunes®
(Apple devices with iOS operating system) store.
A username/password is required, default is: ADMIN/admin.

6
You will see a welcome page similar to below:
Use the links in the NAVIGATION section to access each of the configuration pages,
which are described below.
Network Setup
Check the “Use Automatic IP Address” box to AudioFetch receive its’IP address
automatically (from the network’s DHCP server). Or uncheck this box and enter
values for:
Manual IP Address Subnet Mask Gateway
The values entered must be correct for operation with the connected network,
contact your IT network administrator for instructions if needed.

7
After any changes are made on the NETWORK SETUP page, the “Save Settings”
button at bottom of page must be clicked, otherwise the new settings will be lost at
next power cycle. When this button is clicked, the settings are saved and the
AudioFetch Express box will automatically restart. If DHCP assigns a new/different
IP address after the restart, then use the Doghouse Utility again to reconnect to the
Doghouse.

Wi-Fi Module Network Configuration
The Wi-Fi module networking modes may be selected and configured through the
FetchEx Setup Doghouse Page:
There are some important points one must keep in mind when using this page
to reconfigure the network settings of the Wi-Fi module:
Changing to a new Networking Mode will almost certainly cause your
browser to disconnect from the Doghouse (after clicking the “Save
Settings” button)

9
oYou will need to reconnect your PC/device to the AFE via the new
networking mode, in order to re-establish access to the Doghouse
(just like starting from scratch)
Any mistake made in the settings, could cause the AFE to become
inaccessible after the “Save Settings” button is clicked.
For any problem, best course of action is:
oUse the red User Button to restore factory defaults in the Wi-Fi
Module. (This process is described in the next section)
oReconnect to the default AFE Access Point (SSID:AudioFetchExpress)
oAccess the Doghouse
oStart over again entering the desired new network
configuration settings The general steps to reconfigure the
network mode through this Doghouse page are:
1. Connect to the AFE and access the Doghouse via the AFE’s current
networking mode
a. In Access Point mode: Access the Doghouse through the AFE’s Wi-
Fi network
b. In Access Point & Wireless Internet mode: Access the Doghouse
through the AFE’s Wi-Fi network
c. In Wireless Client mode: Access the Doghouse through the
existing Wi-Fi network
d. In Wired Only mode: Access the Doghouse through the existing
Wi-Fi network
2. If for some reason the Doghouse page comes up showing “unspecified”
for the Networking Mode, it means the settings have not been read in yet
from the Wi-Fi module
a. This would typically only occur if you’ve just powered-on the AFE
and managed to connect to the Doghouse very quickly
b. The module settings are read-in approximately 20 seconds after the
module is booted up –reason for this is to allow the module time to
connect to the existing network (in Client Mode for example) in order
to set the current Wi-Fi channel
c. If this situation ever occurs, just wait a few seconds and then click
the “Restore” button, the settings will refresh within a few seconds.
If not, then try again. If still not then power-cycle the AFE.
3. Adjust the desired settings
a. Nothing on this page is activated or saved until the “Save Settings”
button is clicked
4. Carefully review the settings
5. Click the “Save Settings” button
6. Review the warning dialog that pops up
7. Click the “OK” button in the warning dialog – this will:

10
a. Cause the Status LEDs to begin a “marching” pattern to indicate the
save is still in- progress. The march will be: yellow, green, red,
repeat….
b. Save the new settings (they will survive subsequent power cycles)
i. The save will take some time in the module, the LEDs will
continue marching
c. Then, both AFE and Module will be rebooted
8. After the reboot, the new networking mode should be active
9. If any problem after the reboot (ie: new networking mode doesn’t seem
to work), then first thing to try is a power cycle.
This Doghouse page is designed to be as foolproof as possible:
Only those settings applicable for the selected Networking Mode will be
available for editing (automatically grayed out if not applicable)
Once any setting is changed, a warning notice will appear that the new
settings have not been saved. This warning will persist until one of the
following occurs
oRestore button is clicked
oSave Settings button is clicked and OK is clicked in the warning
dialog
There is a “Restore” button that undoes all the changes
A warning dialog will automatically display if the Save Settings button is
clicked and any required settings are missing
oFor example: if encryption has been enabled but no password
entered
Note: The Restore button does a bit more (behind the scenes) than just undo
any changes entered on the Doghouse page. It actually performs a full re-read
of all configuration settings from the module. So this can be considered a full
“refresh” of the displayed info. Mainly this is useful to re-read the current Wi-Fi
channel being used, especially when the AFE is operating in Client Mode.

11
Multi-Box Setup
Where several audio sources exist (multiple TVs, etc.), multiple AudioFetch and or
AudioFetch Express boxes can be operated simultaneously on the same network, the
AudioFetch App will be able to receive audio from all sources (displayed as different
channels on the App).
When connecting more than one AudioFetch box to the same network, each box will
need to be configured with a unique Multi-Box label in order to be seen
independently on the network. The first box should be set to BOX A, the second to
BOX B and so on (see Picture of the drop down menu below).
Note: When multiple AudioFetch boxes are ordered to work together on the same
network, they will be pre-configured for you and this step will not be necessary.

12
Channel Setup
The CHANNEL SETUP shows the installed channel and allows alternate
names/numbers to be assigned. Important: The “Enable” checkbox should be left
checked.
By default the channel name field is blank. The App will display its default channel
number for this box, as described above.
The channel number displayed by the App may be modified by entering an alternate
number in the “Name” field. The App will display the first four characters of the
name entry instead of the usual channel number. Letters may also be entered (CBS,
ESPN, etc.)
IMPORTANT: The “Save Settings” button must be clicked after any changes are
made, otherwise the new settings will be lost at the next power cycle.
Audio Settings
The Audio Settings page is used to monitor audio signal level, verify which input is
connected/active, and to provide audio gain adjustment.
The current audio status (signal level, active input source) is displayed for the
channel selected from the drop-down list (in AudioFetch Express only Channel 1 is
available), and allows the gain to be adjusted. Status begins updating only after
AudioFetch has connected to the network, therefore when using this page be sure

13
the AudioFetch Express box is connected to a working network (or operating in
Access Point Mode).
To set the Audio Gain:
1. Select the desired channel to adjust from the drop-down list
2. Monitor the Peak Audio Status number, if an active audio source is connected
then it will constantly change.
a. If it remains at 0% then check the audio connections, something is
likely wrong in the cabling or audio source
3. Optimum Peak Audio Status is when the status hits 70% to 90% at its
maximum

14
4. If Peak Audio Status is too low or too high, enter a new value for Audio Gain.
Values entered can be numbers like 7 or 9.0 or 12.5 (the tenths digit can only
be “0” or “5”). Acceptable range is -100.0 to 20.0. Press the Enter key or
click the “Save” button to save the new gain value.
a. After saving, you should notice a corresponding change in the Peak
Audio Status level immediately
b. Keep adjusting the Audio Gain until Peak Audio Status is within
optimum range.
System Status
The System Status page shows basic information about the system and connected
users (see example on next page). Not all information is refreshed automatically,
click the “Refresh” button at the bottom of the page to update the display of latest
status.
Click the “Reset Statistics” button to reset the general statistics in the upper area.

15
Click anywhere in the “Connected Users per channel” area and a detailed list of
currently connected users is displayed with various sorting options provided by the
drop-down selector:
AudioFetch provides additional monitoring statistics online, click the link at the
bottom of the page to access the login page for the online reporting service. Contact
AudioFetch support if you have lost or forgotten your online login credentials.

16
Tools & Utilities
The Tools and Utilities page provides means to change the Doghouse
username/password and options for how firmware updates are delivered to the
AudioFetch box.
To change username/password, enter the current credentials into the first two
boxes, then enter the new username/password into the last two boxes and click the
“Modify Name/Password” button.

17
Other Features in AFE Doghouse
The red status LED operates as an audio clipping indicator automatically during
normal operation. It will turn on whenever the audio signal level is above 90% of
maximum (clipping) level. This is especially useful when operating the AFE with
a microphone.
The Doghouse “Tools and Utilities” page contains a “blink the status LEDs” feature:
The check boxes can be enabled/disabled independently causing any of the Status
LEDs to blink at a slow rate. This is just a convenience feature which allows one to
identify with certainty which physical AFE the current Doghouse applies to, especially
useful if there are multiple AFEs connected to a network.

18
The CONTACT & LINKS page contains contact information in case support is
required, as well as a link to the online portal.
6. Restoring Factory Defaults
Procedure:
1. Power up the AFE and allow it to fully boot (about 35 seconds)
2. Press and hold the red User Button until both green and yellow status
LEDs begin flashing
oIt will take about 5 seconds of continuous press before the LEDs
begin flashing
All three status LEDs will turn off during this 5 seconds
oIf the button is released during the 5 second period when all three
status LEDs are off, AFE operation will resume normally with no
restore of defaults.
3. When both green and yellow status LEDs are flashing together, it indicates
the window is “open” for selecting a factory restore for both AFE and
Wi-Fi Module.
oSelect this option by releasing the button during the time both
green and yellow LEDs are flashing together. This does not execute
the restore, it merely “selects” it. The selection is indicated by both
green & yellow LEDs turning on solid, and the red LED turns on also

19
–to indicate this selection is ready to be executed.
4. Or, instead of releasing the button, continue pressing the button and
eventually (about 4 seconds later) the yellow LED will start flashing by
itself, it indicates the window is “open” for selecting a factory restore for
only the Wi-Fi module.
oSelect this option by releasing the button during the time when only
the yellow LED is flashing. This does not execute the restore, it merely “selects”
it. The selection is indicated by yellow LED turning on solid, and the red LED turns
on also –to indicate this selection is ready to be executed.
5. Or, continue pressing the button and eventually (about 4 seconds later) the green LED will
start flashing by itself, it indicates the window is “open” for selecting a factory restore for
only the AFE (all items in the AudioFetch Doghouse).
oSelect this option by releasing the button during the time when only
the green LED is flashing. This does not execute the restore, it
merely “selects” it. The selection is indicated by yellow LED turning
on solid, and the red LED turns on also –to indicate this selection
is ready to be executed.
6. Continuing to press the button down will cause the LEDs to cycle back
through #3-5, in an endless loop (until button is released).
7. Once the button is released the corresponding selection is display with
constant-on LEDs:
ored, green, yellow all on means the selection is: restore both AFE
and Wi-Fi defaults
ored, yellow on means the selection is: restore only Wi-Fi defaults
ored, green on means the selection is: restore only AFE defaults
8. The selection indication will remain on for approximately 5 seconds. If the
button is pressed again during this 5 second window, the selected restore
will be executed. If the button is not pressed, after 5 seconds the AFE will
return to normal operation (LEDs will go back to normal operating mode).
9. After the restore is executed, both Wi-Fi module and AFE will be restarted.
Total process takes about 35 seconds.
Note: There is a “Restore Factory Defaults” link/button in the Doghouse, this
will restore AFE defaults only, and will not affect the Wi-Fi module.

7. Reference Information - Network Traffic
When AudioFetch Express is used in Access Point Mode, the built-in Wi-Fi is
compatible with all required network traffic to/from connected mobile devices.
However when Client Mode is used to connect to a pre-existing network, it is
important to ensure that the required network traffic is able to flow between
AudioFetch Express and mobile devices running the AudioFetch App. In some
cases minor adjustments to network settings may be necessary, this
information is provided to help IT personnel determine and make the required
adjustments.
