Power factor correction - removes harmonic content on AC line — The NetPA
•
Ultra Series features power factor correction technology that smooths out the high peak
currents of the amplifier 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 Ultra Series to be remotely powered
down when not in use, reducing operating cost.
• High pass filter for high impedance models — The 70V and 100V models feature
a fixed high pass filter on the amplified outputs to prevent saturation of speaker
transformers.
• 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 panel over-temperature LED — 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
