ANTHEM ROOM CORRECTION (ARC™)
–
Persona 9H 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 PERSONA 9H 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 PERSONA 9H 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 allows for 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 calculated by ARC and uploaded to your speaker. You will hear the difference, with
more realistic, better-blended bass response.
