• About the NetPA U 8001 SUB
About this Guide
This guide describes the NetPA U 8001 SUB DSP-enabled subwoofer power amplifier, and
discusses how to install, configure, and operate it.
In this guide, the terms “unit”, “amplifier”, and “power amplifier” refer to the
NetPA U 8001 SUB power amplifier.
About the NetPA U 8001 SUB
The Extron NetPA U 8001 SUB is an ENERGY STAR-qualified, Dante®-enabled subwoofer
amplifier with onboard audio DSP, designed specifically for use with the Extron SF 10C SUB
in-ceiling subwoofer speaker, as well as other 8, 4, or 2 ohm subwoofers with similar power
requirements. The NetPA U 8001 SUB can deliver up to 800 watts at 8 ohms, 650 watts at
4 ohms, or 325 watts at 2 ohms.
The NetPA U 8001 SUB is 1U high, half-rack width, and rack-mountable. The amplifier has
mounting holes for 9-inch (22.86 cm) and deeper rack shelves, and is plenum-rated with an
optional flex conduit adapter. The unit is convection-cooled.
Features
• Receives audio from the Dante audio network as well as from analog line level
inputs — Select a channel from any remote Dante-enabled device on the network, or
an analog source, to be brought into the NetPA U 8001 SUB for amplification.
• 800 watts RMS mono output power at 8 ohms — Allows this single amplifier model
to be used in a wide variety of system configurations.
• 650 watts RMS mono output power at 4 ohms
•325 watts RMS mono output power at 2 ohms
•ENERGY STAR qualified amplifier with defeatable auto-standby and fast wake
up — The NetPA U 8001 SUB is an ENERGY STAR qualified amplifier and energy
efficient product that conserves energy and reduces cost. It meets ENERGY STAR
qualification requirements with an auto-standby feature which automatically places the
amplifier into Standby Mode after 25 minutes of inactivity thereby dramatically reducing
power consumption. It quickly returns to full power status in less than 100 ms upon
signal detection, with minimal inrush current. Auto-standby can be disabled if required.
• Mounts in a rack or directly to an SF 10C SUB — Single and dual rack mount
hardware included.
• Onboard DSP with 4x5 mix matrix — Route any input to any output, with or without
processing, crossover supported.

NetPA U 8001 SUB • Introduction 2
• Frequency range optimized for subwoofers — 20 Hz to 1 kHz.
• Convection cooled, fanless operation — Can be stacked without extra rack space
for ventilation. The NetPA U 8001 SUB does not require internal fans or vents for
cooling, ensuring quiet and reliable operation. It generates substantially less heat than
conventional power amplifiers, making it ideal for rack-mount applications where space
is limited (see Rack Mounting Ventilation Recommendations on page 3).
• Extron Patented CDRS - Class D Ripple Suppression — CDRS is an Extron
Patented technology that provides a smooth, clean audio waveform and an
improvement in signal fidelity over conventional Class D amplifier designs. CDRS
eliminates the high frequency switching ripple that is characteristic of Class D amplifiers,
a source of RF emissions which can interfere with sensitive AV equipment such as
wireless microphones.
• Setup and configuration with Extron DSP Configurator Software — Via a Dante
network or USB.
• UL 2043 plenum rated when used with optional Flexible Conduit Adapter Kit —
The NetPA U 8001 SUB meets UL 2043 for smoke and heat release for installation
within a plenum airspace above a drop ceiling when used with the optional Flexible
Conduit Adapter Kit. Above-the-ceiling placement conceals the amplifier to prevent
theft, and is convenient for installing equipment when space inside the room is limited.
• Professional grade signal-to-noise and THD+N performance — The NetPA U
8001 SUB delivers professional grade performance, featuring 100 dB signal-to-noise
ratio and THD+N of less than 0.1%.
• Ultra low inrush current at power up - no need for power sequencing — Allows
multiple NetPA Ultra Series amplifiers to be powered on simultaneously without
overloading power circuits. This eliminates the need for power sequencing.
• Power factor correction - removes harmonic content on AC line — The NetPA
U 8001 SUB features power factor correction technology that smooths out the high
peak currents of the amplifier’s current draw thereby minimizing the presence of high
frequency harmonics on the AC power line and preventing audible artifacts from being
transmitted to other audio equipment in the system.
• Automatic clip limiter — Detects actual onset of clipping. Gain is automatically
reduced without audible artifacts to protect speakers from clipping distortion.
•Multiple protection circuits — Activate during output shorts, thermal overload, or DC
faults to prevent damage to the amplifier and speakers.
•Remote standby port — Enables the NetPA U 8001 SUB to be remotely powered
down when not in use, reducing operating cost.
• 5 mm screw-lock captive screw speaker connectors — Enable simple, secure
connections with 22 to 12 AWG speaker cables.
•Front and rear-mounted signal and protection indication LEDs — Provide
convenient indication of input signal presence and protection circuit activation from both
sides of the equipment rack.
•Front and rear panel over-temperature LEDs — Provides visual indication that the
amplifier temperature has exceeded the optimal value, well in advance of the onset of
thermal protection circuitry.
• Internal Extron Everlast™ power supply — Provides worldwide power compatibility,
with high-demonstrated reliability and low power consumption for reduced operating
cost.
• Extron Everlast Power Supply is covered by a 7-year parts and labor warranty
