X-Connect

High-resolution wireless audio transmission

X-Connect and X-Connect Surround are Nubert's own digital wireless standards for wirelessly networking speakers, amplifiers and other Hi-Fi or home cinema devices. Both variants score with high-resolution signal quality, low latency, stable transmission and simple operation.

Many current Nubert products such as the subwoofers of the nuSub series, the active speakers from the nuPro XS series or the compact integrated amplifier nuConnect ampX already have X-Connect or X-Connext Surround on board. Other Nubert components and compatible devices from other brands can be upgraded in no time using the nuConnect trX adapter.

For the transmission of audio signals, the Nubert X-Connect standards are far superior to conventional WLAN technology. Thanks to stable, bidirectional data connections with low latency and high bandwidth, the Nubert wireless systems achieve the highest sound quality and interference-free connectivity. As a result, both systems enable wireless listening pleasure at the highest level. Multiple transmission frequencies allow interference-free operation in parallel with existing wireless technology.

Examples of X-Connect applications

Two XS-3000 RC are wirelessly connected to each other as a stereo pair.

The XS-3000 RC stereo pair is complemented wirelessly by a subwoofer to form a 2.1 set.

A nuConnect ampX amplifier acts as an interface between traditional passive speakers and modern wireless systems, e.g. in a 2.1 system with passive speakers and a wirelessly connected subwoofer.

A nuConnect ampX integrated amplifier acts as an intermediary between traditional passive speakers and modern wireless systems, e.g. with passive speakers in the main zone supplemented by X-Connect compatible speakers in a second zone. Or the other way around.

AV application: traditional AV receivers are connected wirelessly to rear boxes or subwoofers using a nuConnect trX.

Usage examples for X-Connect Surround

Expand your soundbase wirelessly with dedicated surround speakers from 5.1 to 7.1.4 with full compatibility with Dolby Atmos and DTS:X

Compact and yet extremely powerful AV sets are made possible with the nuXinema preAV. It also allows a mix of traditional wired systems, whether passive or active, and wirelessly linked systems, especially attractive when used with surround and ceiling speakers and subwoofers.

Similarities

Technical underpinnings are identical
Uncompressed, lossless hi-res quality
Minimized latency (19 ms) and uninterrupted transmission
Automatic selection of different frequency bands in the 5 GHz range
Transmission of control commands, e.g. volume setting, tone control, etc.

Differences

X-Connect is optimised for stereo applications, while X-Connect Surround enables convenient connection of speakers in surround mode.

Maximum Channels

X-Connect: 2
X-Connect Surround: 8

Sampling Rate

X-Connect: 192 kHz / 24 bit
X-Connect Surround: 48 kHz / 24 bit

The higher channel count of X-Connect Surround requires a lower sampling rate to efficiently process data volume and latency both technically and acoustically. No compression is applied.

Control Commands

X-Connect: Forward transmission of control commands from master to client devices (e.g., volume, tone control, display settings).
X-Connect Surround: Bidirectional transmission of control commands and information.

This enables the recognition of client devices (possibly with automatic level calibration), and the transmission of control commands such as power on/off or volume adjustment allows for basic operation of the entire system directly from the client devices.

Number of Clients per Channel

X-Connect: Any number, different types can be mixed.
X-Connect Surround: 1

This means that X-Connect Surround allows for automatic volume level adjustment in surround systems and enables the exchange of advanced control commands. Caution when using subwoofers: Only one subwoofer can be connected. If multiple subwoofers are to be wirelessly connected, for example, to a nuXinema preAV, it is recommended to use a nuConnect trX on the Sub Out.
