At DALI, we believe that digital music should deliver convenience
DALI CALLISTO C:
HI-FI REIMAGINED
and choice without compromise. That’s why we’ve reimagined hi-fi
for the 21st century with the CALLISTO C Wireless Speaker System.
CONNECT PLAY HEAR MORE
Whether you’re listening from a music
server or a smartphone, a CD or a streaming
service, we believe you should hear music
at its ver y best. With a host of inputs, from
traditional wires to Bluetooth aptX HD, plus
future-proofed expansion ports, CALLISTO
C is ready to connect the way you want to.
At DALI, we’re driven by a single-minded
mission: to deliver music to the listener
exactly as the artist intended. Because
we believe that, while the way we listen
to music has transformed, the reason we
listen remains the same: to feel, to laugh, to
cry, to dance… to feel something special.
“The way we listen to music has been transformed.
But the reason we listen remains the same”
The CALLISTO C Wireless Speaker
System brings your digital music to life in
ways you’ve never experienced before.
We do it by combining what we do best –
hand-crafted Danish construction with the
cutting-edge electronics we pioneered in
our award-winning active speaker systems.

DALI SOUND HUB
The DALI SOUND HUB is the brains behind your CALLISTO C
speaker system, wirelessly transferring hi-res audio to your speakers
and automatically switching between multiple sources.
he sound hub brings true nocompromise convenience to music
T
and movie lovers who demand more.
Featuring an auto source sensing system,
and a huge range of digital and analogue
inputs, the sound hub automatically activates
the right input the moment you start playing
music or turn on your TV – so you can just sit
back and enjoy exquisite audio.
Thanks to our low-latency, 30-bit protocol,
the sound hub can transfer an uncompressed
hi-res (24-bit/96Khz) signal to each speaker
and still have headroom for control signals.
That means all you need to worry about is
adjusting the volume using CALLISTO C’s
Bluetooth remote or directly via touch panels
built into the top of each speaker.
BLUETOOTH
With proven wireless technology as standard, the sound hub lets
you stream music to the CALLISTO C system from most devices.
The sound hub supports Bluetooth’s latest, hi-res apt-X HD format,
alongside the AAC format favoured by Apple devices.

transfer to the CALLISTO C speakers
The dual optical inputs are controlled
independently for audio and TV. Seamless
sync between your TV picture and sound is
ensured by the system’s sub-25ms latency
SUBOUT
An LFE type subwoofer output. When
a subwoofer is connected, everything
below 100Hz is sent via this output to

COAXIAL RCA
For direct digital connection between an
audio device and the sound hub. Like the
optical input, it will accept signals from
16-bit/32kHz to 24-bit/192 kHz
USB POWER
The built in USB A port delivers a 5V 1A
output to power connected devices like
Google Chromecast Audio, or charge
a mobile device while playing

DALI TECHNOLOGY
Here at DALI, we’ve made it our life’s work to challenge
perceptions of what great audio is. With CALLISTO C we
take another leap forward because, for the first time, the
entire audio chain is in the hands of our R&D team.
AMP AND DRIVER IN
PERFECT HARMONY
Performance needs power, and designing
an all-new active speaker system like
CALLISTO C required unique amplifier
modules that could be set up to perfectly
match each driver – elevating audio
performance way beyond conventional
passive speakers.
Each CALLISTO C speaker is driven by
a powerful, dual-channel 250W Class D
amplifier, based on patented state-ofthe-art technology chosen for its musical
properties. This works in perfect harmony
with the Power Supply Unit (PSU) and the
signal processing to achieve undistorted,
uncoloured amplification.
HYBRID TWEETER
PERFORMANCE
Our trademark hybrid tweeter module –
a dome tweeter combined with a ribbon
tweeter – allows for amazing rendering of
high frequencies, plus a dispersion of highfrequency audio that outperforms all other
tweeter technologies.
The soft dome membrane is ultra
lightweight and works with the optimised
magnet system to deliver better control and
greatly limited distortion.
The ribbon tweeter, combined with the soft
dome, results in extreme bandwidth and
ultra-wide dispersion. This is the essence
of DALI’s lauded sonic definition.
“By controlling the entire signal path from
source to driver, we are able to elevate audio
performance beyond conventional speakers”
Page 13
THE BEST WOOFER
– BUT BETTER
Taking something great and making it
better is our raison d’être at DALI, so
we borrowed well-known elements from
our OPTICON and RUBICON woofers
and used advanced computer simulation
to optimise the magnet motor. Then we
added a Soft Magnetic Compound (SMC)
pole piece and combined it all to imbue
the CALLISTO C series with an agile and
ultra-low-loss woofer.
Every element of the CALLISTO C woofer
is optimised to work in perfect balance with
the built-in amplifier, and because of this,
the soundstage created is detail-rich, timecoherent and eortlessly immersive.
The result? Music reproduced exactly
as the artist intended.

FUTUREPROOF
EXPANSION
At DALI, we build hi-fi to last for decades, not months.
That’s why we’ve future-proofed the CALLISTO
system with two modular ports that open up a world
of possibilities – now and in the years to come.
dding new features to your
CALLISTO C couldn’t be easier
A
thanks to the sound hub’s twin
expansion ports. Our DALI-designed,
open-standard connector allows new audio
services to be fully integrated and even
enables additional features like multi-room
and multi-channel audio.
BLUOS: WIRELESS WITH MORE
Our first expansion module integrates
Bluesound’s incredible BluOS hi-res
multi-room platform. BluOS is devised
by audiophiles for audiophiles to deliver
the best digital sound quality imaginable
throughout your house. And because
Bluesound is compatible with speakers
from a variety of audiophile manufacturers,
it delivers flexibility, convenience and
choice as well as unparalleled quality.
All of which make it a natural extension
to the CALLISTO wireless family.
