Cyrus ONE HD

Power and scale with a wealth of features

Product Information:

The Cyrus ONE® HD extends the versatility and performance of the original Cyrus ONE adding multiple digital inputs
as well as improving critical signal path components. Conceived as a truly integrated amplifier, just add speakers to
get audiophile quality performance from any source.

Now in its 4th generation, the Cyrus Hybrid Class D amplifier with S.I.D. (Speaker Impedance Detection) calibrates
itself to perform optimally with any loudspeaker it encounters. With 2 x 100W of power, it is capable of driving even
notoriously difficult speakers to exceptional standards.

Inputs now include digital asynchronous USB, Optical, SPDIF and aptX
DAC specifically engineered to produce an optimum performance for each of these inputs. The built-in passive
RIAA MM phono stage is now separated from the main circuit, lowering the noise-floor and providing an even better
performance when directly connected to a turntable.

Control is provided by a dedicated Bluetooth app, downloadable for both Apple and Android devices. This allows full
control of input switching, volume setting, adjustment of the brightness of the display LEDs and configuration of the
AV mode, should you wish to integrate your Cyrus ONE

Cyrus ONE

Bluetooth Enabled - aptX®HD:

aptX® HD compatible Bluetooth enables you to stream
better than CD quality music from your phone/tablet or
computer via a wireless Bluetooth connection, providing
maximum flexibility without the need for a home network or
any complicated set up. This allows everyone in the family
to enjoy their music from their portable devices quickly and
easily.

High-power Amplier:

2 x 100W gives class-leading power output that will drive
most loudspeakers regardless of their size. All that power
enables Cyrus ONE
dynamic range, giving 3D detail and bags of energy without
the need to buy big, bulky, inefficient amplifier boxes.

MM Phono Stage:

Cyrus ONE HD features a built-in phono stage that is
compatible with all Moving Magnet cartridges and requires
no adjustment or extra set up, enabling you to play all your
favourite vinyl from most turntables.

HD features and benets:

HD to present your music with a huge

HD with your existing home theatre amplifier.

Digital and analogue inputs:

Asynchronous USB, optical and SPDIF inputs enable you
to connect your PC, TV, Games Console, CD player, indeed
virtually any source, directly to the Cyrus ONE
analogue inputs include RCA terminals for a turntable
and an AV input that can be set to fixed gain in order to
integrate with a separate AV amplifier.

Class AB Headphone Amplier:

Uniquely, when headphones are connected, the large
toroidal transformer is switched to power just the
headphone section. These huge reserves of power result
in a high power, high voltage class AB headphone amplifier
that will drive almost all headphones with ease. The
resulting musical performance is on a par with most stand­alone headphone amplifiers

Speaker Impedance Adjustment:

SID – Speaker Impedance Detection automatically matches
the amplifier’s output response to the electrical load of the
loudspeakers. This means that matching Cyrus ONE
to any brand of loudspeaker has suddenly been made so
much easier.

Cyrus ONE HD

Integrated amplifier

ONE HD

The Cyrus ONE HD is designed in a clean, simple, elegant non-ferrous chassis that minimizes eddy currents
and reduces pickup of external noise. Extensive mains supply filtering is used to reduce the impact of this noise
which has the ability to colour the audio performance.

Suggested Systems

The Cyrus ONE HD is an exceptionally powerful
amplifier capable of driving even large form-factor
loudspeakers from almost any analogue or digital
source. It remains a relevant component in high-end
systems costing many thousands of pounds.

The ability to run the Cyrus ONE
amplifier in AV bypass mode enables it to be easily
integrated into any home theatre system whilst still
offering amazing musical performance.

As a high-performance amplifier system, headphone
amplifier, or as an integral part of an AV system, the
ONE

HD is class-leading.

A perfect complement to the Cyrus ONE
Cyrus ONE linear speakers have been specifically
designed to benefit from the Hybrid Class D
topology used in all Cyrus ONE models.
