Know before you buy
Transient Power Correction provides a 45-amp reservoir of current on demand. This ensures that your power amplifiers have immediate access to the energy they need during dynamic musical peaks, preventing the compression that often occurs with standard power strips.
Unlike standard protectors that degrade or fail after a single major surge, the PowerQuest 909 uses non-sacrificial circuitry. It is designed to withstand repeated high-voltage spikes up to 6000V/3000A without needing to be replaced.
The outlets are specialized for different tasks. The 4 high-current outlets are designed for power-hungry components like amplifiers and subwoofers, while the 8 linear-filtered outlets are optimized for source components like DACs, streamers, and preamps to ensure a lower noise floor.
It comes with a high-performance 2-meter PQ-920 AC power cable. This cable is specifically engineered with advanced noise-dissipation technologies to complement the conditioner’s performance.
The unit features Extreme Voltage Shutdown, which monitors the incoming power. If it detects a dangerous voltage level, it will automatically shut down the output to protect your connected equipment from damage.
Yes, the PowerQuest 909 is designed for professional integration and includes a 2RU rack-mounting kit, making it easy to install directly into standard AV equipment racks.
