Intended to bring “linear noise-dissipation and non-sacrificial surge protection” to a wider audience, the new lower-priced PQ-303 ($460), PQ-505 ($700), and PQ-707 ($1,300) power conditioners are designed to withstand AC surges and spikes up to 6,000 volts/3,000 amps without sustaining damage and feature automatic shutdown with extreme voltages (up to 140VAC).
Each rack-mountable model (2RU rack ears included) is equipped four High-Current outlets for variable-current components such as amplifiers and powered speakers and eight Source outlets for constant-current devices such as TVs and streaming media players.
The PQ-303 is said to provide linear noise dissipation via a differential filter with an operating range of 30 kHz-1 GHz, while the higher priced PQ-505 and PQ-707 are rated for “ultra-linear” noise dissipation through the combination of the same differential filter (but with a lower 8 kHz rating in the case of the PQ-707) and a common-mode filter with an operating range of 30 kHz-100 MHz. The top-line PQ-707 adds a 45-amp on-demand current reservoir.
Each model ships with a detachable a 6.5 foot (2 meter) “direction controlled” power cable designed to dissipate RF noise and has a flat-to-wall plug. For more information, visit audioquest.com.
