NOTE: Consult with your authorized Acurus dealer or Acurus
support regarding pricing and availability of expansion
options for your Aries."

system planning and
optimizing
#
In order to experience the best performance from your
integrated amplifier, the entire system needs to be planned
and components carefully selected to work together. Your
authorized Acurus dealer is trained to be able to help you
ensure your components work well together. #
#
The following are some helpful guidelines to ensure your
Acurus integrated amplifier is well-matched to the other
components in your system. #
#
1. Quality loudspeakers can have a dramatic impact on
overall sound quality in a system for a given room
environment. When planning or upgrading a system, as
a rule of thumb, we recommend budgeting for
loudspeakers at or somewhat above the price of your
amplifier electronics. Your Acurus dealer will be able to
advise you on best loudspeaker selection for your
electronics, your environment, and, most importantly,
your listening preferences. #
2. Using higher-efficiency loudspeakers (87dB/W/m or
greater) will reduce the average amount of amplifier
power consumed to produce a target listening loudness.
This effectively helps reserve greater peak amplifier
power when loud transient passages are reproduced. #
3. High-power amplifiers (over 100W continuous into 8
ohms) are generally OK to pair with speakers with
slightly lower power ratings, particularly if subwoofers
are involved. Higher-power amplifiers will tend not to go
into clipping distortion as readily as lower-powered
amplifiers or receivers. Clipping is a type of distortion
that is prone to damage loudspeakers. #
4. Preamps should be chosen with output voltage swing
capability equal to or greater than the amplifier
sensitivity spec for full rated power output (for example,
1.42V for full rated output). Similarly, an ideal preamp
choice has a noise spec less than or equal to that of the
power amplifier. Using the Aries line output with other
Acurus-branded amplifiers ensures a perfect match.#
#
#
#
#
!
ARIES placement and
setup
#
An enjoyable home entertainment experience always begins
with carefully planned placement and setup of system
components. This section will provide guidance on how to
best install your new Acurus integrated amplifier. #
#
Shelf Mounting "
When planning to mount on a shelf, be aware of the physical
dimensions of your Acurus integrated amplifier as outlined in
the section entitled “Technical Specifications”. #
#
It is ALWAYS advisable to: #
1. Provide ample space above the unit (1-2 inches is the
minimum preferred) #
2. Provide plenty of room (at least 1-2 inches) between the
sides of the unit at nearby surfaces or other components #
3. Locate the unit near an AC outlet or power conditioner
and avoid using extension cords or power strips #
4. Locate the integrated amplifier as close as possible to
audio source units such as optical players or music
servers #
5. Use as short length wire leads as practical, especially
on the amplifier inputs #
6. Connect the integrated amplifier to the same mains
circuit as audio source units#
#
It is NEVER advisable to: #
1. Enclose the unit in a cabinet without air flow or
adequate ventilation, particularly across the heat fins
along the side and back of the unit. #
2. Place the unit near a source of moisture such as a
window or a live plant #
3. Place other components in a stack on top of the
amplifier #
4. Place the amplifier on a carpeted surface #
5. Remove the safety ground connector from the AC mains
cord #
#
Rack Mounting "
Your Acurus integrated amplifier can easily be configured to
mount in a standard 19-inch rack cabinet with an optional
Acurus rack mount accessory kit, ARM-3. Hardware and
detailed installation instructions are included with the kit. See
your authorized retailer or contact Acurus to obtain a rack kit
for your Aries. #

Connecting the IR Target"
To enable control of the Aries with an IR remote, the IR
target must be plugged into the rear of the unit. TheAries
IR target is a 5V unit.#
IR target 3.5mm stereo plug
1 – Ground
2 – IR Signal
3 – 5V DC
NOTE: Use only the IR target included with your
Aries. Pin-out and operational voltages of IR target
devices vary. Use of an incompatible device could
possibly damage the unit."
#
#
Mains (AC) Power "
Your Acurus Aries is equipped with a high-quality 14
gauge, 3-conductor power cord. Plug this cord into the
back of the integrated amplifier and then into a nearby AC
outlet. Avoid using any extension cords or plugging into
other components with rear-panel switched outlets. If using
Aries with a power conditioner, ensure that the receptacle
your integrated amplifier plugs into is capable of providing
the full current required. See section entitled “Technical
Specifications” for Aries AC current draw requirements.#
#
Control Networks "
Ethernet: In order to take advantage of Acurus Enhanced
Ethernet Control (E2C), connect the Ethernet port to a
10/100 or faster home network router or switch port via a
standard CAT 5e or newer Ethernet cable. The network
activity indicator near the Ethernet jack illuminates green
when network activity is detected. #
#
This port may also be directly connected to a system
controller utilizing Ethernet command protocols. Contact
your dealer or Acurus Customer Service in order to verify
compatibility with certain control systems. #
#
RS-232: Connect this port to a system controller using a 9-
pin RS-232 serial cable in order to control and monitor the
Aries remotely. Contact your dealer or Acurus Customer
Service in order to verify compatibility with certain control
systems. #
#
#
making system
connections
Your Acurus amplifier is designed for simple, reliable
connections in a variety of system configurations. Following
the instructions below will ensure optimal performance from
your Aries integrated amplifier. #
#
NOTE: Making system connections with AC power
disconnected is ALWAYS recommended."
#
"
Connecting Loudspeaker Outputs "
Use a high-quality loudspeaker cable with sufficient gauge
wire for the loudspeaker run lead length. Be sure to observe
consistent speaker polarity connections (plus (+) and minus
(-) speaker leads) from amplifier to loudspeaker. TheAcurus
Aries is non-polarity inverting.#
#
Physical connection options supported include bare wire,
single banana post, dual banana post, spade connector and
wire lead. #
#
Before powering on the Aries, check to ensure speaker plus
and minus leads are not touching each other or touching
other connectors or the unit chassis.#
#
Connecting Audio Source Inputs "
Use a high quality RCA and/or XLR cabling to connect audio
source devices to Aries inputs. Avoid coiling or bunching up
of cables. Be sure RCA cables are fully inserted into Aries
input jacks so as to avoid hum and other signal integrity
problems. #
#
Trigger In and Out Control"
To enable an external power conditioner or AVR to power on
your Acurus Aries, connect the trigger out from that device
to the the 3.5mm 12V trigger in on the Acurus. The jack is
wired with its tip active and will accept a stereo or mono
plug. #
12V trigger 3.5mm stereo plug
1 – Ground
2 – Ground
3 – Trigger Voltage
NOTE: the front panel power button functions
normally even if the trigger input is used. The Acurus
amplifier will automatically resume control sync with
the external device after the next time system power
is cycled.

The unique Aries v-drop function enables you to keep
audio playing at a reduced listening level when you need to
be interrupted momentarily. It works very similarly to a
mute function. With v-drop, the Aries output volume is
reduced to the level preset in the v-drop settings menu.
Unlike mute, you can still hear a slight amount of audio in
the background. This setting determines the v-drop

ARIES design notes
#
#
#
The Acurus Aries was designed by engineers at Indy Audio
Labs to deliver an audio experience rivaled only by a live
performance. We refer toAries as our “concert system” in one
compact unit. #
#
While other high-end components may draw attention to
themselves cosmetically or sonically, the Aries was conceived
differently. Aries was conceived as a high-end product so
simple to use, so compact and so transparent in operation that
it delivers a dramatic musical event without getting in the way.
The goal of Aries is to deliver a rich user experience in the
least obtrusive manner possible.#
#
To deliver on Aries goal from an audio perspective, a solid,
neutral power amplifier must be utilized. The power amplifier
should be able to reproduce the broadest possible musical
styles without imparting its own coloration on the program
material. We chose 200W per channel as the target power
spec since this tends to support larger rooms and less efficient
loudspeakers with ample power for music transient peaks. We
also wanted to ensure we chose an amplifier design capable
of driving low impedance loudspeakers (3-4 ohms nominal)
with ease. In order to achieve these stringent amplifier
specifications while simultaneously maintain as compact a
chassis as possible, we developed and introduced in Aries
Acurus’ first ever analog class D switching power amplifier
technology. This new Acurus amplifier platform remains true to
Acurus musicality and neutrality while boasting all the
advantages of class-D switching technologies such as
compactness and low heat dissipation. Acurus engineers were
able to achieve all the above design goals with this new
platform, unique to the new Aries integrated amplifier.#
#
At the front end of the Aries, much like other legacy Acurus
integrated amplifiers and pre-amplifiers, care has been taken
to ensure signal paths are kept short and utilize minimal or no
gain stages. This ensures that the source signal is not altered
in any way from audio inputs to internal amplifier front-end
stages. We utilize low-noise, ultra-low-distortion digitally-
controlled volume circuits and discrete high-performance
audio relays for basic source switching, muting and volume
adjustments. Subwoofer filtering is performed in the analog
domain with no DSPs in the signal path. This keeps
processing artifacts out of the signal and maintains the most
natural-sounding performance. #
#
In addition to the subwoofer out, a full left-right pre-amp output
feature is included in Aries. This allowsAries to control an
external amplifier such as an Acurus A2002 driving a second
set of loudspeakers. Or, if additional power is warranted
beyond Aries built-in 400W amplifier platform, an external
amplifier can be connected to allow speaker wiring for a bi-
amplified configuration. TheAcurusA2002 is a perfect match
in gain for this option and would result in delivery of a total of
400W to each loudspeaker.#

The front panel controls of the Aries are modern, minimalist
and meant to be unintimidating for even the listener least
familiar with audio separates. What is required is simply a
basic understanding of the icons and symbols used universally
in modern mobile devices and tablet PCs. TheAries takes full
advantage of this modern graphical approach to
communicating status information. The result is a product
which is easy to learn and operate and conveys a more
modern design approach than most of its peers in the audio
industry.#
#
Like all other Acurus products developed recently by Indy
Audio Labs, the Aries approach to web connectivity provides
the user with the simplest possible means to control their
audio system with a smartphone or tablet. Aries does all the
network “heavy lifting” behind the scenes so that the user
doesn’t need to download any apps or set any network
settings. The user simply enters the IP address displayed on
the Aries screen in their mobile device web browser. The
user’s mobile device then mimics the front panel display of the
Aries for full audio control from anywhere within the home.#
#
As user needs change and as technology advances, an
expansion slot in the rear of the Aries makes the system ready
to evolve. The rear-panel expansion slot in theAries allows for
future cards from Acurus which add 1 to 3 additional inputs
such as digital audio, phono, wireless and other technologies
yet-to-be conceived. Authorized Acurus dealers can provide
additional information about the availability and pricing of
expansion cards as they are released. TheAries owner can
feel confident that Aries can be updated as new source
devices are added to the system. #
#
All-in-all, the Aries is a full-featured, flexible, yet extremely
simple solution for a wide variety of modern 2-channel audio
applications. Whether for pure audio listening, audio-for-video,
audio-for-gaming or any other applications where surround
processing is not needed or warranted, Acurus engineers are
confident that you’ll find Aries delivers an exceptional all-
around experience.#
