# \&inputchannels

Sender-Side Option! ([`&push`](https://docs.vdo.ninja/advanced-settings/setup-parameters/push))

## Aliases

* `&channelcount`
* `&ac`

## Options

Example: `&inputchannels=6`

| Value             | Description                                 |
| ----------------- | ------------------------------------------- |
| `1`               | Audio capture device set to mono; 1 channel |
| `2`               | Audio capture device set to 2 channels      |
| `6`               | Audio capture device set to 6 channels      |
| (integer value X) | Audio capture device set to X channels      |

## Details

`&inputchannels=N` tells the audio capture device explicitly to select N-number of audio channels. 

Setting [`&stereo=0`](https://docs.vdo.ninja/advanced-settings/audio-parameters/stereo) will set `&inputchannels=1` by default.

If using [`&proaudio`](https://docs.vdo.ninja/advanced-settings/audio-parameters/and-proaudio) you want want to disable stereo-audio capture, particularly if you are using an XLR to USB microphone preamp that has two channels, but only one microphone connected.

For example, if a guest joins and you can only hear them in the left or right channel, either add [`&mono`](https://docs.vdo.ninja/advanced-settings/audio-parameters/mono) to the view-link or add `&inputchannels=1` to the respective guest invite-link.

### Mono-specific alias

If looking for a memorable parameter to set a guest's audio input to mono (1-channel), [`&monomic`](https://docs.vdo.ninja/advanced-settings/audio-parameters/and-monomic) is the same as `&inputchannels=1`. This was added in VDO.Ninja v22.
