# Connections

> Available inputs on Manta, and how to connect the speakers with analog or digital cables.

> [!WARNING]
>
> Always make sure the loudspeaker is powered OFF before connecting or disconnecting cables.

## Available connections

| Connection | Description |
| - | - |
| Balanced (XLR) | Balanced analogue input and through output. |
| Digital (AES, S/PDIF coaxial and optical) | AES and coaxial input and through output, optical input. Max sampling rate 192 kHz (optical 96 kHz). |
| Unbalanced (RCA) | A stereo input signal is internally mixed to mono. For mono use, simply connect only one of the channels (left or right) or use a Y-split. |
| USB | Connect your laptop to access the parametric EQ and additional settings. Otherwise for maintenance and service only. USB audio is not supported. |

## Analog connection

The easiest way to think of the MANTA is as speakers with built-in mono power amplifiers. This means they can be connected to a pre-amplifier or processor with either RCA or XLR stereo outputs, the same way you would with a power amplifier.

You can also connect the MANTA directly to a source, for instance a network streamer (with volume control).

Your pre-amp or source also needs an additional pre-out or subwoofer output to enable you to connect your subwoofer(s). Using a Y-split is also possible if only one pre-out is available. Using XLR connections and dual subwoofers, you can also connect the subwoofers directly via the speakers using the XLR Through connection. See [Subwoofer integration](https://docs.sigbergaudio.com/speaker-systems/manta/subwoofer-integration.md).

Option: dual subwoofers connected via XLR through

## Digital connection

When connecting digitally (AES or TOSLINK), both speakers will receive a stereo signal. Your MANTA speakers are preconfigured as a L+R pair that will pick up the individual left or right channel.

**1. Find the left and right speaker**

Inspect the serial number label on the rear of the speaker. The identical serial numbers will end with "L" and "R" respectively.

**2. Place the speakers**

Place the speaker labeled "R" as the right speaker, and the speaker labeled "L" as the left speaker.

### Check the channel configuration

Press the **select** button on the speaker and hold it for 3 seconds. Either "Left", "Right" or "Left+Right" will light up to indicate the current configuration.

### Change the channel configuration

If you wish to change the configuration, or accidentally did so: press the **select** button for three seconds and keep pressing. The configuration will change and cycle through "L", "R" and "L+R" every 1.5 seconds.

It can also be done using the HFD software. See [Adjusting defaults](https://docs.sigbergaudio.com/speaker-systems/manta/adjusting-defaults.md).
