RBO Power Ace Master & Power Ace Noi C

1 December 2025

Smart power control and cleaner mains for pedalboards, amps and studio rigs

The Power Ace Master and Power Ace Noi C bring two practical upgrades to any pedalboard, amp or studio setup. The Master offers a clean and convenient way to switch an entire rig on or off, while the Noi C tackles unwanted hum at the power input without touching the protective earth. Both plug straight into any IEC socket, making them easy additions to modern and vintage gear alike.

The Power Ace Master is built for players who want a tidy board and quick power access, using a compact inline switch that avoids crawling under a pedalboard or behind rack gear. Unlike lightweight alternatives, it is rated for higher current, so it works with most pedalboard power supplies and studio equipment. The Power Ace Noi C focuses on ground-loop hum, filtering low-frequency noise at the mains input while keeping the PE connection intact. Its inline IEC design makes it a simple plug-and-play fix for amps, effects units and rehearsal room or venue power, with a blue LED confirming operation.

Key Features:

  • Inline IEC on/off control for convenient rig power management
  • Inline hum and noise reduction without lifting protective earth
  • Compact designs that integrate easily into pedalboards, racks and amp setups

Together, these two accessories offer a practical upgrade for anyone fighting cable clutter or persistent mains noise. Players who gig often, switch between venues or run complex setups will appreciate the reliability and simplicity. A smart pairing for clean power and cleaner tone.
