ANTHEM ROOM CORRECTION (ARC™) – Founder 120H Only
A True Scientific Solution to the Problems of the Room
Anthem Room Correction Technology is a proprietary digital signal processing system
that allows you to quickly and accurately optimize the performance of your Founder
120H to better suit the unique parameters of your room.
By listening to your room's acoustic signature, ARC can tune your equipment to
correct for the performance-robbing effects (reflections, resonances, standing waves,
etc.) of the various surfaces and other obstacles in your room.
ARC is easy to use, and just a few simple steps can customize your Founder 120H
for your unique listening space. ARC is sophisticated, one of the most accurate and
detailed digital room correction technologies available today. ARC will work tomorrow,
too; with constant advances and updates available for download on the Anthem
website.

WHY ARC?

ARC is a state-of-the-art room correction system that analyzes bass response in your
room, and then sets the correct equalization parameters to attain optimal sound. ARC
improves bass response and enhances seamless dynamic blending.
Computer-assisted ARC applies super-efficient Infinite Impulse Response (IIR)
Filters, in addition to Custom Filter Topology, to minimize delay and reduce
processing noise. If any audio artifacts could overcome this unique combination of IIR
plus Custom Filtering, they would be so small as to be completely inaudible. ARC is
just that effective.
ARC requires multiple microphone measurements. Most room equalization methods
work from only a single point source, taking one measurement at the "primary
listening position." ARC measures room response from at least five user-selected
measurement points (up to ten positions may be measured), beginning with a "main
measurement position." Additional measurement positions are symmetrically spaced
a minimum of 2 feet from the first position (see diagram). This multi-measurement
process ensures optimal bass performance throughout the listening area.
Unlike other "Room EQ" systems, ARC applies correction to peaks (modes) and dips
(anti-modes). Correcting both allows ARC to achieve a far more accurate and natural
room response. To limit the demands on the amplifier and maximize signal-to-noise
ratio, ARC applies appropriate limits to this correction.
ARC is Ultra-Accurate! Your own computer's 64-bit floating-point processor does the
hard work of calculating the correction curves, which greatly minimizes the rounding
errors common with less sophisticated room
correction systems

HOW DOES ARC WORK?

The "room correction" process begins when a
test signal generated from your speaker and is
picked up by the ARC calibrated microphone. The
system then runs a frequency sweep to highlight
possible problem areas and determine necessary
adjustments. Once your ARC measurements
are captured by the microphone and saved on
the connected PC, the optimized solutions are
12
calculated by ARC and uploaded to your speaker.
