1. SOUND HUB Overview
The DALI SOUND HUB is a control preamplifier and source
selection hub for DALI wireless speaker systems such as the
OBERON C, CALLISTO C and RUBICON C series.
The DALI SOUND HUB takes both wired audio sources and
wireless audio streams and broadcasts them wirelessly to
connected active speakers.
The SOUND HUB has five wired audio inputs and can
also connect to Bluetooth audio devices. The wired inputs
comprise analogue mini-jack and RCA phono sockets, a
coaxial digital input, and two TOSLINK optical digital sockets.
SOUND HUB Bluetooth is compatible with the SBC, AAC,
aptX and aptX HD audio streaming formats. In addition to its
wireless speaker connections, the SOUND HUB is fitted with
mono subwoofer and stereo preamplifier outputs.
The input and output capabilities of the DALI SOUND HUB
can be expanded by the installation of one or two optional
modules:
The NPM-1 and NPM-2i modules employ the BluOS
streaming platform to enable the SOUND HUB to play audio
from a range of network streaming services, music libraries,
internet radio and USB storage. The NPM-2i module differs
from the NPM-1 module by incorporating Apple Airplay 2
streaming technology. Installation and use of an NPM module is
described and illustrated in
The HDMI module adds an input for HDMI ARC or HDMI eARC
equipped TVs and incorporates Dolby Digital and DTS decoding
to enable the SOUND HUB to broadcast to multi-channel
speaker systems. Installation and use of the HDMI module is
described and illustrated in
.
HDMI eARC (sometimes referred to as HDMI 2.X) is a
technology that enables far higher quality audio performance
than HDMI ARC. In particular, eARC is able to transmit up to 8
channels of uncompressed, high-resolution audio from a TV to
audio devices such as a DALI SOUND HUB. If your TV offers
both ARC and eARC connection or settings options, always use
the eARC option to connect your DALI SOUND HUB.
The SOUND HUB can be controlled using either its front
panel controls or the supplied Bluetooth connected remote
control. If an NPM module is installed, the SOUND HUB can
also be controlled via the BluOS Controller app, and if an HDMI
module is fitted a TV remote control can also be used for some
functions.
