Power Quest 707

AudioQuest PowerQuest 707

The AudioQuest PowerQuest 707 is an advanced power conditioning model that can be rack-mounted or free-standing in a hi-fi system. The PowerQuest 707 builds on AudioQuest's comprehensive approach to AC power conditioning, addressing noise in a linear manner to provide industry-leading noise cancellation over a wide frequency range (better than -22dB).

The PowerQuest 707 offers advanced linear noise cancellation, including differential mode filtering (8 kHz - 1 GHz), to address asymmetric noise already present on the power line or returned through electronic devices and components. Additionally, it provides ultra-linear noise cancellation by adding Common-Mode filtering (30 kHz - 100 MHz) to address symmetrical noise, which is typically picked up by the AC line, neutral and ground cables.

A notable feature of the PowerQuest 707 is Transient Power Correction (TPC). TPC provides a current reservoir of up to 45 amps of peak power on demand for each amplifier (up to 25 ms), giving the amplifier the low impedance power needed to deliver exciting dynamic contrasts, bass extension and control.

In terms of protection, the PowerQuest 707 is equipped with non-sacrificial overvoltage protection and automatic shutdown under extreme voltage. If excessive surge voltage is detected on the incoming AC line for more than a quarter of a second, the circuit will immediately activate a high current relay, shutting off AC power to all PowerQuest outlets, and flashing the red LED on the front panel activates as a warning for the overvoltage protection. Once the event has passed or the wiring fault has been resolved, the circuit automatically turns back on, giving you confidence in protecting your valuable connected equipment.
