The V-1HD⁺ has multiple ways to connect audio sources:

• Analog XLR - These are the 3 pin locking connectors
• Analog RCA - These are the red and white phono connectors
• Digital HDMI - The video inputs also accept audio embedded within the video signal

This guide covers 2 different workflows:

• Using the V-1HD⁺ to mix all of your audio
• Using an external audio mixer with stereo or mono output to the V-1HD⁺

Muting Audio Channels

---

The first thing you want to do when setting up a V-1HD⁺ is to mute any audio channels you do not plan to use. In most cases, this is some or all of the HDMI inputs.

When you go to the Audio Input menu, the HDMI settings are listed first:

• Input 1 through Input 4 are for the HDMI inputs
• Audio In 1 and Audio In 2 are for the XLR inputs
• Line In is for the RCA inputs

Note that you can also use the Audio Mixer in the iPad Remote App to adjust these settings.

 

Here are some examples. Note that you only want to mute HDMI audio channels you are not using:

• Menu > 8: Audio Input > Input 1 > Input Mute > On
• Menu > 8: Audio Input > Input 2 > Input Mute > On
• Menu > 8: Audio Input > Input 3 > Input Mute > On
• Menu > 8: Audio Input > Input 4 > Input Mute > On
  
  
• If you plan to output a camera's microphone or laptop's audio via HDMI to the V-1HD⁺, do not mute that HDMI input.
• The Digital Gain setting for each embedded audio input is a pre-fader trim you can use to adjust the level before any EQ or Compressor processing.

Tip: When navigating the submenus, press the MENU button to go up one level.

 

Even if your HDMI source does not output any audio, it is recommended to mute that audio channel, because in some cases, the source may generate noise that will be part of your audio mix.

You can also set up Audio Follows Video, which unmutes an HDMI source when it is visible on PGM:

V-1HD⁺: How to Set Up and Use Audio Follow Video in your Audio Mix

 

Muting unused analog input channels is not necessary, so long as the gain and level knobs on the V-1HD⁺ are turned all the way down for those channels:

Microphone Setup

---

This section covers microphones that are connected directly to the V-1HD⁺ mic inputs. If you are using an external audio mixer, you can skip to the next section.

To set up a microphone, first you need to determine what type it is:

• Dynamic
  • These microphones need a lot of head amp (aka preamp) gain
  • They do not need phantom power
• Condenser
  • These microphones need less head amp gain
  • They are more sensitive to noises in the room
  • They need phantom power
• Lavalier
  • These are clip on microphones
  • The amount of head amp gain needed varies
    • Wired
      • These need less head amp gain
      • Can be very sensitive to room and clothing noises
      • They also need phantom power
    • Wireless
      • Head amp gain varies, because the level is also controlled via the mic belt packs
      • In most cases, they do not need phantom power

 

In this example, we connected a dynamic microphone to Audio In 1, and a condenser microphone to Audio In 2:

Once connected, turn up the audio level knobs for Audio In 1, Audio In 2, and MAIN on the V-1HD⁺'s audio mixer to the orange dot at 2 o'clock, which is 0 dB:

 

Next, turn on Phantom Power for Input 2 using the menu:

Menu > 8: Audio Input > Audio In 2 > Phantom +48V > On

 

Next, set your Head Amp (aka preamp) gain using the Gain knobs.

This setting will vary, depending on the microphone, and the voice of the person using it.

 

Turn up the GAIN knob for each mic input until you get a good sounding level, and the Level LED above the Audio In 1 and Audio In 2 knobs are Green or Yellow, but not Red: 

 

Next, press the SETUP button to open the AUDIO INPUT menu on the Multi-View output:

You can also long press this button to enable Stereo Linking for external audio mixers, which will be covered later in this guide.

 

Here are some example settings to review in the AUDIO INPUT menu for the two different types of microphones in our example:

• Dynamic Microphone
  • Audio In 1 > Head Amp Gain > 50 dB
  • Audio In 1 > Digital Gain > 0.0 dB
  • Audio In 1 > Input Level > 0.0 dB
  • Audio In 1 > Pan > Center
    
    
• Condenser Microphone
  • Audio In 2 > Head Amp Gain > 35 dB
  • Audio In 2 > Digital Gain > 0.0 dB
  • Audio In 2 > Input Level > 0.0 dB
  • Audio In 2 > Pan > Center

 

As a general rule, do not pan microphones that people are speaking into, your dialogue should be centered.

Also, do not adjust the Digital Gain setting, this is for advanced setups that need additional headroom for adding EQ and Compression. More info is in the Reference Manual.

If you have a camera microphone that you want to center in the mix, some cameras only pan audio sources left and right. You can center it in the V-1HD⁺ by using the Mono setting:

• Menu > Audio Input > Input X > Mono > 
  • The L Only setting centers the left channel and mutes the right channel
  • The R Only setting centers the right channel and mutes the left channel
  • The LR Mix setting combines and centers both the left and right channels

External Audio Mixer Setup

---

To set up an external audio mixer, there are two ways to connect it using the XLR and RCA inputs.

 

XLR Inputs 1 and 2

This method preserves a balanced connection. XLR and 1/4" TRS connectors are balanced.

Use either a XLR to XLR cable, or if your audio mixer has TRS outputs, use a TRS male to XLR male cable.

Note that TRS cables are very similar to TS cables, which are unbalanced:

 

Turn down all the volume knobs on the V-1HD+ before making connections.

 

Connect your external audio mixer's left and right outputs to XLR inputs Audio In 1 and Audio In 2 on the V-1HD⁺.

 

Press and hold the Setup (Link) button until it is solid green.

• This setting simplifies external audio mixer setup. Audio In 2 will follow Audio In 1's settings, and pan the inputs left and right for stereo.
• You can also find this setting in Menu > Audio Input > Audio In 1 > Setup (Link) SW > On.
• If your external mixer is a single mono output, do not turn on Setup (Link) SW and later check that Pan is Center.

 

Turn the knobs for Audio In 1 and MAIN to the orange dot at 2 o'clock:

 

Next, press the SETUP button to open the AUDIO INPUT menu on the Multi-View output:

 

Check that the following settings match.

• Menu > Audio Input > Audio In 1 > Head Amp Gain > 0 dB
• Menu > Audio Input > Audio In 1 > Digital Gain > 0.0 dB
• Menu > Audio Input > Audio In 1 > Input Level > 0.0 dB
• Menu > Audio Input > Audio In 1 > Pan > Disabled when Setup (Link) SW is on

 

 

Calibration (Advanced)

Output a test tone from your audio mixer to calibrate the signal level. You may need to add a small amount of Head Amp Gain using the GAIN knob to get the signal level to match.

If you are not familiar with calibrating audio levels, you can skip this step, as the mix level will already be very close.

 

The stereo meters on the V-1HD⁺ multi-view and Remote App audio mixer are in dBFS, a digital scale where the highest value is 0dB, and anything over that is clipping. This is not the same as a VU meter.

So, if you output a 1 kHz sine wave test tone at a +4 dBu reference level, it should appear as -16 dBFS on the V-1HD⁺, and 0 dBu reference would be -20 dBFS.

Note that dBu, VU, and dBFS are all different scales, so the values are different between each of them.

 

 

RCA Line Inputs

You can instead connect an audio mixer's RCA outputs to the the RCA inputs on the V-1HD⁺:

 

Then, turn the Line In knob to the orange dot at 2 o'clock:

 

If you need to run a long cable between the audio mixer and video switcher, consider using the XLR inputs for a balanced connection.

If you want a balanced connection but your mixer only has RCA outputs, connect a short RCA cable to a line converter box, which will convert the output to XLR, and you can run that cable a long distance to the V-1HD⁺ with a balanced connection.

Additional Tips

Create A Settings Backup File

Once you have your final audio settings, it's recommended to create a backup file. This can be done saving a file to a USB flash drive using the V-1HD⁺ menu.

More information is on page 40 in the Reference Manual.

 

Prevent Scenes From Changing Audio Settings

When you create a Preset Memory (aka Scene), your audio settings are included. If you do not want your audio settings to be recalled with scenes, you can disable that in the Load Parameter submenu.

• Menu > 11: Preset Memory > Load Parameter - Audio Input > Off
• Menu > 11: Preset Memory > Load Parameter - Audio Output > Off
• Menu > 11: Preset Memory > Load Parameter - Audio Follow > Off

Audio settings will still be saved to scenes, but they will not be recalled.

More information is on pages 38 and 55 in the Reference Manual.

 

Enable Panel Lock for Audio Knobs

If you have a number of people operating the V-1HD⁺, it may also help to enable Panel Lock. This is a feature located in the System menu that allows you to disable specific knobs and buttons on the V-1HD⁺.

• Menu > 17: System > Panel Lock > Audio Level > Off

Note that this locks the Audio In 1, Audio In 2, Line In, and Main knobs.

This is particularly helpful if you have an external audio mixer and do not want anyone to accidentally adjust the Main volume on the V-1HD⁺.

More information is on page 42 in the Reference Manual.
