Setting Up Surround Audio

To pass surround audio from HDMI inputs to HDMI or S/PDIF outputs you must have an HDMI sink (display, AVR, etc.) that supports
one or more surround formats. Follow these steps to configure the DVX to pass-through surround audio.
1. Connect a source that is capable of providing surround audio to an HDMI input on the DVX.
2. Connect a sink that supports surround audio to an HDMI output on the DVX.
3. See Using a Web Browser section on page 59 and follow the instructions to open the DVX Web Configuration page.
4. To manually select an audio format to request from the source (switcher firmware 1.4.4 or higher):
On the Audio In tab, select the HDMI Input connected to the source.

Select the desired surround format from the HDMI Audio options menu.

5. To pass an HDMI sink's audio capabilities to the source device:
On the Video In tab, select the HDMI Input connected to the source.

Select Mirror Out x from the EDID Mode options menu where x is the output number connected to the surround-capable

sink (see item 6 in the Video In section on page 62 for more information.)
6. In the HDMI Output section of the Audio Out tab, select the HDMI output that is the destination for surround audio and then
Select Input Pass-Thru from the Audio Source options menu (see item 3 in the Audio Out section on page 64 for more
information).
7. If sending surround audio to the S/PDIF output, select the same HDMI output used in step 6 above in the S/PDIF Output
Audio Source options menu (see item 4 in the Audio Out section on page 64 for more information).
8. Route the video from the HDMI input connected to the surround audio source to the HDMI output selected in step 6 above.
Follow these same steps when receiving surround audio from a DXLink input and/or sending audio to DXLink outputs. Connect all
DXLink transmitters/receivers to the DVX, connect sources and sinks to DXLink transmitters/receivers, and select the appropriate
DXLink input/output on the DVX in the steps above.

Embedding Audio on an HDMI Output

Follow these steps to configure an HDMI, DXLink or S/PDIF output to embed audio from a stereo source:
1. Connect either a digital audio source on an HDMI input or an analog audio source on one of the analog audio inputs.
2. Connect an HDMI sink (display, AVR, etc.) that can accept audio over HDMI.
3. See Using a Web Browser section on page 59 and follow the instructions to open the DVX Web Configuration page.
4. In the HDMI Output section of the Audio Out tab, select the HDMI output that is the destination for audio and then select the
analog output you want to embed from the Audio Source options menu. (See item 3 on Audio Out section on page 64 for
more information).
5. Route the desired input audio (connected in step 2) to the analog output chosen in step 4, and it will automatically embed on
the selected HDMI and/or S/PDIF output.
6. In the HDMI Output section, select the Apply EQ check box if you want the audio on the HDMI output to be affected by the
DVX's Volume and Equalizer settings. De-select this box if you want un-equalized, unity gain audio on the HDMI output
(recommended if adjusting volume and EQ at the downstream HDMI sink).
7. To send the same analog audio to the S/PDIF output, select the same Analog output used in step 4 above in the
S/PDIF Output Audio Source options menu (see item 4 in the Audio Out section on page 64 for more information).

Mixing Microphones onto Analog and HDMI Outputs

Follow these steps to connect and mix audio from a microphone input onto the source audio being routed to an audio output. The
Mic inputs can accept both Microphone level and Line level audio.
1. Connect an audio source to one of the microphone inputs on the DVX.
2. See Using a Web Browser section on page 59 and follow the instructions to open the DVX Web Configuration page.
3. On the Audio In / Microphone tab, select the appropriate Pre-Amp gain setting for the input type you are using (see item 7 in
the Audio In/Microphone section on page 65 for more information):
If the input source connected to the microphone input is a line-level signal, adjust the Pre-Amp Gain for that microphone

input to 0.
If the input source connected to the microphone input is a microphone-level signal, adjust the Pre-Amp Gain for that

microphone to a setting above 0 (typical values are between 20 and 30 dB).
4. If the connected microphone requires phantom power, check the Phantom Power check box for that microphone input (see
item 6 in the Audio In/Microphone section on page 65 for more information).
5. In the same section, turn on the connected microphone by checking the Enable check box for that microphone input.
6. On the Audio Output tab, select each analog audio output (see item 1 in the Audio Out section on page 64) and adjust the mix
level as desired for each output (see item 10 in the Audio Out section on page 64).
To hear both program audio and microphone audio on an analog output, start by setting the mix sliders for both the Input

and the Mic all the way up and then make minor adjustments to these sliders to achieve the desired relative audio levels.
To hear only the program audio on an analog output, set the microphone mix levels all the way down (-100) and the Input

mix level all the way up.
