ARC (ANTHEM ROOM CORRECTION)
The Easy-To-Use Anthem
Room Correction Kit
Delivers Professional
Results In Any Room
What is ARC?
Simply put, Anthem Room Correction
quickly “corrects” the effects that reflective
surfaces such as walls, floors and ceilings
have on the sound radiating from a
loudspeaker. Removing the effects
of these obstacles allows your audio
equipment to achieve a more natural
sound in any room, as close to the lab
standard as possible.
On a more complex level, ARC is a
proprietary digital signal processing
software that works with a specially-
engineered calibration microphone and
your PC to quickly and easily optimize
audio for your unique listening space.
Anthem engineers developed the
ARC system while researching how
to replicate the audio-lab standard of
performance in non-lab environments.
This groundbreaking research was
conducted in conjunction with
the National Research Council
of Canada, the Canadian
government’s research and
technology organization.
Anthem engineers realized that real
world listening experiences had little in
common with the controlled environment
of the audio lab. That’s because even the
best loudspeakers are affected by room
anomalies like furniture. These obstacles
cause standing waves, resonances, and
reflections that can color the sound
you hear. Imagine the sound waves
coming from your speakers as ripples on
a water surface. That makes it easy for
you to understand how the ripples of
sound bounce off any obstruction they
encounter. You can immediately see the
benefit of removing the obstacles.
ARC digitally compares a room’s acoustic
signature to that of the lab standard. It
measures the response of each speaker
relative to the listening area. Then it uses
advanced algorithms to eliminate the
negative effects of the obstacles in the
room, adjusting response and correcting
phase effects. When ARC removes the
obstacles, what’s left is the lab standard
performance.
ARC also detects how much the room
reinforces low frequencies due to its
boundaries and pressurization. ARC senses
where each speaker’s low-frequency
response declines and sets high-pass filters
accordingly, ensuring natural-sounding
levels of deep, well-blended bass.
ARC does all this, and more, instantly and
automatically. The result is a replication
of the lab standard right in your room,
for “perfect” speaker performance in any
listening space.
How does it work?
The ARC Kit is easy to use, and just a
few simple steps can customize your
loudspeakers for your unique listening
space.
Each ARC-ready component comes
with a complete ARC Kit, consisting of
software and microphone calibration file
from our website, a professional quality
mic stand and high quality connectors.
You will need a Windows-based laptop
computer with a CD drive.
Plug the kit’s custom Calibration
Microphone into your computer and into
your ARC-ready Anthem AVM 60. Place
the microphone at each of the listening
positions in your room (a minimum of
five, maximum of ten), and allow ARC to
take a sound sample from each location.
The proprietary ARC software measures
the difference between the speaker’s
ideal lab-standard response, and their
real-world performance in your room.
Then, its sophisticated DSP accurately
equalizes response and creates intricate
crossover curves so that the performance
of the speakers in your room meets the
ideal lab standard!
Now you’re hearing exactly what our
audio engineers intended you to hear:
Pure, natural, transparent sound, no
matter what challenges your room
presents!
