Extron electronics NetPA Ultra Series User Manual page 10

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
• 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
