## Inputs

<guide-columns>

In Miroir Remote, open **Settings → Audio** and select your device. Under **Mic mix**, select the two channels that carry the studio voices together. This mix must contain only the microphones, with no audio returned from the Director 4K.

### Prepare the RØDECaster

On the console, use firmware **1.7.3 or later** and connect the Director 4K to **USB 1**. Keep microphones on matching-numbered faders, with pan centered.

Under **Settings → Outputs → Multitrack → USB**, choose **Pre-fader** or **Post-fader**. In pre-fader mode, **Bypass Processing** records unprocessed audio.

</template>

<template v-slot:rodecaster-routing="">

Under **Settings → Outputs → Routing → USB 1**, choose **Custom** and send only microphones in use, without the USB return.

### Prepare the RØDECaster Pro

On the console, under **Settings → Advanced → Audio**:

- **Multitrack**: enable **USB**;
- **Processing**: enable **USB Mix-Minus**.

<template v-slot:mixer-inputs="">

Use the mixer’s manual to find the USB pair carrying only the microphone mix and the individual channels of your microphones. Enter the **Mic mix** pair in Miroir Remote and adjust the mixer’s USB send if needed.

</template>

<template v-slot:interface-inputs="">

Find the USB channels for the microphone mix and each individual microphone in the interface’s manual. Enter the **Mic mix** pair in Miroir Remote. Configure routing if the interface supports it.

</template>

<template v-slot:output-heading="">

## Outputs

Connect headphones or speakers to your audio device. In Miroir Remote, open **Settings → Audio → Interface outputs**.

</template>

<template v-slot:output-mixes="">
<guide-columns>

For the outputs in use, choose what you want to hear:

- **Monitoring headphones**: studio microphones, content and remote guests.
- **Monitoring speaker**: content and remote guests, without studio microphones.

<template v-slot:figure="">
<guide-figure :height="436" :width="896" alt="USB output pair assigned to the Monitoring speaker mix" src="/images/studio/ui/audio-outputs.webp" path="Settings → Audio → Interface outputs">



</guide-figure>
</template>
</guide-columns>
</template>

<template v-slot:rodecaster-outputs="">

Under **Interface outputs** in Miroir Remote, assign **Monitoring headphones** or **Monitoring speaker** to **Output 1-2**, depending on your listening setup. The corresponding mix is sent to the RØDECaster over USB.

On the RØDECaster, open **Settings → Outputs → Routing**, choose **Custom** for each headphone or **Monitor** output in use and send **USB 1** only. Those outputs then follow the Deck’s mutes.

<template v-slot:rodecaster-pro-outputs="">

Under **Interface outputs** in Miroir Remote, assign **Monitoring speaker** to **Output 1-2**, even when using headphones.

On the RØDECaster Pro, raise the **USB** fader to hear sound from the Director 4K. This console adds local microphones directly to headphones and **Monitor** outputs, even when muted on the Deck. Its **Monitor** outputs therefore cannot provide a microphone-free mix.

</template>

<template v-slot:mixer-outputs="">

Find the mixer’s USB playback channels for your headphones or speakers and enter that pair under **Interface outputs**. Route only the USB return to those listening outputs so they follow the Deck’s mutes.

</template>

<template v-slot:interface-outputs="">

Find the USB playback pair for your headphones or speakers, often **1–2**, and select it under **Interface outputs**. Disable **Direct Monitor** or set **Input/Playback** to **Playback**.

</template>

<accordion-item label="Use your monitoring display’s speakers?">

If your monitoring display has built-in speakers, you can use them instead of separate speakers. They receive the mix without microphones over HDMI or DisplayPort.

## Check the audio

<accordion>
<accordion-item label="No microphone signal">

Under **Settings → Audio**, watch the meters while the person speaks. If no channel responds, check the microphone connection and the device’s USB send.

If individual channels respond but voices are missing from the program, also check the **Mic mix** pair. During the session, check **MIC** and the **Microphones** level in **Live**.

</accordion-item>

<accordion-item label="Picture and voice are out of sync">

This setting corrects **lip-sync**, the timing between sound and picture.

Under **Advanced settings**, adjust the audio delay in milliseconds. If you hear the voice before the lips move, increase the value to delay the sound. If you hear it after, decrease the value without going below **0**. Then click **Save**.
