The Hypex NCx500 is a continuation of the excellent NCORE line. Offering nearly 2x the performance improvement over the last generation NC500 OEM module, the NCx500 represents a significant step forward for Hypex amplifiers, with up to 700 watts of power per channel (all channels driven) at extremely low distortion and an imperceptible noise floor level.
The 3ch NCx500 amplifier is perfect for those who want the absolute best amplification for a Front LCR setup; whether it be for Home Theater usage, critical Music usage, or a combination of both.

NOTE: Our 3ch NCx500 amplifier uses an exclusive 2kW SMPS from Micro Audio to fully power all three channels without any of the drawbacks of our competitors, including superior thermal management. The Micro Audio SMPS also brings with it Active Power Factor Correction.

You have a choice of two different gain stages during checkout (both are the same price and both sound identical):
  • Hypex gain stage, which renders our Low/Med/High toggle switch inactive (gain cannot be changed). This configuration is best for use with an AV Receiver and/or when using other Hypex amplifiers in your setup.
  • Buckeye gain stage, allowing for Low/Med/High gain settings via toggle switch on the rear. This configuration is best for use in setups with a source/DAC capable of higher pre-out voltages.
The gain stage can be switched via internal jumpers by the customer if future setups dictate the need to change.

Custom I/O Board:

  • Neutrik XLR connectors
  • Gold plated 5-way speaker binding posts
  • Low, Med, High Gain settings (if using our Buckeye gain stage)
  • Error Indication (via front power LED)
  • Auto Sensing On/Off
  • 12v trigger On/Off
  • Muted soft-start/shutdown (minimizes speaker “pop” when turning on and off)
Gain settings when using our Buckeye gain stage:
  • 4 ohm - 24.2dB/3.3Vrms (High), 19.2dB/5.8Vrms (Medium), 14.2dB/10.3Vrms (Low)
  • 8 ohm - 24.2dB/3.4Vrms (High), 19.2dB/6.0Vrms (Medium), 14.2dB/10.8Vrms (Low)
Gain setting when using the Hypex gain stage:
  • 4 ohm - 26.8dB/2.4Vrms
  • 8 ohm - 26.8dB/2.5Vrms
The Hypex gain stage matches up with the input gain of the Hypex NCxxxMP amplifiers, perfect for those wanting to mix the NCx and NCxxxMP amplifiers (such as for a home theater setup).

While our amplifiers use XLR inputs, it is perfectly fine (and fully supported by Hypex) for customers to use RCA to XLR cables to connect the amplifier to a source that only has RCA outputs.

Our cases may not be much to look at, but unlike our competitors who use overseas manufacturing, we have all of our cases manufactured in Nova Scotia, Canada (Protocase, Inc). This is part of our commitment to keep as much of our amplifiers as "home grown" as possible. It also ensures the highest possible quality aluminum and extremely precise CNC manufacturing.
