Introduction
High-End All-Digital Preamp-Processor with Fully Customizable Features for Serious AV
Enthusiasts
The NuForce AVP-18 all-digital HT preamp/processor offers dedicated AV enthusiasts true,
24/192 digital audio performance and superb HD video at an amazing price. With four HDMI
inputs, two optical and two coaxial S/PDIF inputs, the AVP-18 easily accommodates the most
complex system configurations. Supported digital audio formats include:
•DTS-HD Master Audio
•DTS Neo:6
•Dolby TrueHD
•Dolby Pro Logic Iix
•Dolby Pro Logic Iiz.
In order to focus on the best possible digital-to-analog conversion (DAC) performance, the AVP-
18 accepts only digital sources, thus permitting the DAC and following analog stages to include
the same innovative technology utilized in several of NuForce’s high-end audio DACs. In
addition, the AVP-18 offers audiophile-grade analog circuitry throughout, along with a high-
precision analog volume control and superior-quality RCA output connectors, all of which
contribute to the AVP-18’s pristine clarity. For the headphone enthusiast, the unit also includes a
headphone output that provides both standard 2-channel and Dolby surround listening.
Unlike many similar processors, switching between HDMI inputs on the AVP-18 is smooth and
precise. The HDMI output and all four HDMI inputs are fully HDMI 1.4 compliant with 3-D, CEC
and SRC support. For the last word in flexibility, the AVP-18 also accepts an ARC input from
your TV. Indeed, the AVP-18 is so feature-packed we can’t list everything here. ( For further
information, please see Features section below. )
While casual users will find initial setup a breeze, the AVP-18 still provides the demanding
audiophile all of the controls necessary to customize performance to the highest levels of
precision. To get started, connect your digital sources, plug in the calibration microphone
(included), and activate the automatic multi-channel room correction software to adjust for the
inevitable acoustic anomalies typical of most rooms. Once done and with all settings now
stored in memory, you can start enjoying the latest HD audio and video media with the
assurance that you are experiencing the kind of accurate, transparent and musical sound upon
which NuForce’s reputation rests.
While the AVP-18’s automatic calibration routine makes getting started simple and
straightforward, the serious audiophile still has the opportunity to seek perfection by way of an
advanced array of calibration options including:
•Quadruple-bass-management settings
•Eleven programmable, fully parametric equalizers per channel
•Adjustable speaker crossover points, slopes and alignment types
•Balanced and unbalanced subwoofer outputs
•Front channel bi-amplification capability.
With the AVP-18 as its cornerstone, you’ll have the ideal foundation for building the ultimate
audiophile HT system. Add one of our highly acclaimed MCH and MCA Series multi-channel
amplifiers, a full compliment of our award winning Reference Series mono-block amplifiers, or
some combination thereof and you'll find yourself immersed in a universe of true audiophile
cinema and sound.

Setup for Room Equalization
The intelligent acoustic room scanning involves a testing mic. It can automatically test the
number of connected speakers, the optimal inflection point frequency and the distance
between speakers and the audience. Through capturing noise in the room, it will adjust
frequency and time thresholds to solve distorion problem caused by noise. The scanning
system can also automatically set the EQ. The equalizer with 11 segments can maintain the
balance withtin obtave. Before doing the acoustic scanning, please make sure all speakers are
connected.
Connecting the testing mic:
•Connect the test mic included in the package to the SETUP MIC jack on the rear panel
before scanning. Place the mic in the main listening position and parallel with the
listener’s ear when sitting down. Make sure the mic is standing up straight with the
sensor pointing up. In order to ensure the accuracy of the testing, please do not hold or
touch the mic while doing the acoustic scanning.
