Description
Dali Sound Hub Compact : Transmitter Wireless
Dali Sound Hub Compact transmits your audio sources to the wireless Dali eco system, which includes Oberon C, Callisto C and Rubicon C speakers. The Sound Hub Compact was designed with compact dimensions and is slim enough to fit behind a wall-mounted TV.
Seamless Integration
Designed with seamless TV integration and Bluetooth audio in mind, the Dali Sound Hub Compact wireless audio preamplifier combines all the functions and interface facilities needed to play the central role in a complete wireless active Hi-Fi system. It can handle a variety of wired digital and analogue sources including HDMI ARC and also pairs with Bluetooth devices such as smartphones, tablets, laptop and PCs to enable wireless audio playback.
The Sound Hub Compact can be installed on a table, shelf or furniture unit or be direct wall-mounted using its keyhole slot features. The system will automatically switch on when a previously paired Bluetooth device is connected and playback initiated. There’s no complex control app to learn, just automatic input switching and intuitive source based volume control.
Reliable Wireless
The Sound Hub Compact and Oberon C wireless connection is highly stable and introduces next to no packet loss. The robust nature of the wireless connection means that the Sound Hub Compact can be located as much as 10 m apart from the speakers without risk of connection failure or signal interruptions.
Sound Hub Compact transmits using a proprietary 30 bit wireless protocol broadcast over the 5.2 GHz or the 5.8 GHz band which is derived from the acclaimed Dali Sound Hub. This transmits uncompressed I2S audio at 24 bit/96 kHz resolution and utilises the remaining six bits for feed-forward error correction, volume control, speaker identification and other functional requirements.
Optical Input
The Sound Hub Compact Optical S/PDIF Input 1 is intended for the connection of CD players or other conventional digital audio sources fitted with a digital optical output. The Optical S/PDIF Input 2 is intended for the connection of TVs fitted with a digital optical output. The auto switch on function of Optical Input 2 is activated by the carrier light in the optical connection, rather than the audio signal, which ensures that the Sound Hub Compact is ready to play TV audio as soon as the TV is switched on.
Wireless Bluetooth
The Sound Hub Compact Bluetooth input features AAC and aptX HD high performance codecs and enables smartphones, tablets, laptop or desktop computers, or any other Bluetooth audio source easily and quickly to play either locally stored or streamed music. Even Bluetooth equipped TVs can be connected to create a completely wireless TV audio solution.
Analogue Input
The analogue line input is intended for conventional audio sources such as CD players or preamplifiers. Turntables can be connected directly if fitted with a line output, or connected via an RIAA phono preamplifier. The analogue input is where audiophile tradition meets the future of wireless active Hi-Fi. The analogue to digital conversion stage following the input generates a high resolution, better than CD, 24 bit/ 96kHz data stream.
Sub-out
The Sound Hub Compact provides a volume controlled, line-level analogue sub output that switches on automatically when a connection is detected. The subwoofer output is low-pass filtered at 100Hz to match the frequency characteristics of the main speakers. When a subwoofer is in use, the audio transmitted to the main speakers is high-pass filtered to reduce its energy content below 80Hz and preserve power handling in the main speaker frequency band.
USB Power
The wireless adaptor incorporates a USB-A socket that’s primarily intended for service and diagnostic use. The USB socket can however also be used to charge a mobile device or to power a media streaming device such as an Amazon Echo or Google ChromeCast Audio, the output from which can then be routed to a Sound Hub Compact input and potentially introduce a voice control element to the system.
IR Signal Receiver
The unit includes a wired IR Signal Receiver accessory that enables it to be located out of line-of-sight of its remote control handset. The IR Signal Receiver is optionally connected to a Sound Hub Compact rear panel socket. Connecting the IR Signal Receiver disables the Sound Hub Compact integrated IR receiver.
