CLOSEOUT SALE:
With the release of the Purifi Gen 2 offerings (the 1ET9040BA and the 1ET6525SA), we are discontinuing our 1ET7040SA monoblock offering. In doing so, we are having a closeout sale on our remaining Purifi 1ET7040SA monoblocks. The sale price INCLUDES the upgraded Micro Audio SMPS1k-PFCR2 power supply (which allows the 7040SA monoblock to reach full rated output power compared to our competitors) AND we are also including the Micro Audio Capacitor PCB Board upgrade (4x10000uF).


The Purifi 1ET7040SA is the big brother of the highly regarded 1ET400A. While the 4 and 8 ohm output is nearly identical to the Purifi 1ET400A, the 1ET7040SA shines for those with sub 4 ohm speaker loads (40A peak current capability vs. 25A peak of the 1ET400A). The Purifi 1ET7040SA is capable of up to 950w of power while maintaining extremely low distortion and noise floor levels.

With its completely flat frequency response and ultra high-power output, a pair of our Purifi 1ET7040SA's are a top tier choice for those with critical 2ch listening setups that utilize extremely hard to drive speakers, allowing for users to hear the source material as it should be without any added distortion or "coloring" of the sound.

Custom I/O Board:

  • Neutrik XLR connectors
  • Gold plated 5-way speaker binding posts
  • Low, Med, High Gain settings
  • TI OPA1612 OP Amp
  • TI TPS7A30/49 Voltage Regulators
  • Auto Sensing On/Off
  • 12v trigger On/Off
  • Muted soft-start/shutdown (minimizes speaker “pop” when turning on and off)
  • Clipping Indication (via front power LED)
  • Error Indication (via front power LED)
Gain Settings
  • 4 ohm - 25.5dB/2.4Vrms (High), 20.5dB/4.2Vrms (Medium), 15.5dB/7.5Vrms (Low)
  • 8 ohm - 25.5dB/2.4Vrms (High), 20.5dB/4.2Vrms (Medium), 15.5dB/7.5Vrms (Low)
High input gain setting matches up with the input gain of the Hypex amplifiers, perfect for those wanting to mix Purifi amplifiers with Hypex amplifiers (such as for a home theater setup).

RCA vs. XLR
While our amplifiers use XLR inputs, it is perfectly fine (and fully supported by Purifi) 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.
