El AudioQuest PowerQuest 505 is a power conditioner This high-performance surge protector is designed to enhance the visual and audio experience in stereo and home theater systems. Its primary purpose is to deliver clean, consistent power to your devices while acting as an impenetrable shield against power surges. It is aimed at home users and audiophiles seeking to maximize signal purity without compromising the safety of their audiovisual equipment.
Filtration ultra-linear noise
The system dual-mode ultra-linear filtration It effectively eliminates interference that degrades the sound and image quality of your equipment. This technology directly targets electrical noise present in your home network, ensuring that your hi-fi or home theater components receive an electrical signal of maximum purity.To achieve this deep cleaning, the conditioner addresses both asymmetrical and symmetrical interference with outstanding effectiveness. This results in a much quieter musical background, where the subtle details of your recordings emerge without distortion or masking, improving the overall dynamics of the system.
The technical features of this filtering module include:
- Differential filter that acts from 30 kHz to 1 GHz
- Common-mode filter that operates as 30 kHz to 100 MHz
- Superior wideband noise reduction -22 dB
In practice, by connecting your audio sources and screens to this power conditioner, you will notice a clear improvement in image sharpness and greater instrumental separation in the sound, free from the usual electromagnetic interference.

Outstanding Features from Audioquest PowerQuest 505
Reduces noise across a wide bandwidth for cleaner sound.
Protect your equipment from voltage spikes without sacrificing performance.
Isolation between outlets to prevent cross-contamination.
It minimizes noise induced by the electrical grid for a better signal.
Protection professional grade electrical
The system non-sacrificable surge protection This ensures your valuable audiovisual equipment remains undamaged in the event of severe power outages. Unlike conventional surge protectors that burn out after a voltage spike, this model withstands repeated power surges of up to 6000V and 3000A without suffering damage to its internal circuits.The function of Extreme Voltage Shutdown (EVS) It acts as a smart shield against dangerous voltage spikes. If the voltage reaches the 140 VACthe main power circuit relay activates in less than 0,25 secondscutting off the power completely to prevent the anomaly from reaching the connected devices.
The advantages of this comprehensive security system are highlighted by its autonomy:
- Continuous protection that does not require replacement of internal fuses
- Sudden cut-off in the event of extreme voltage spikes
- automatic reconnection once the network is stabilized
This way, you can enjoy your stereo or home theater equipment with complete peace of mind. You'll know that even during thunderstorms or sudden power outages, your investment in electronic components is protected by an unbreakable, automatic barrier.

Distribution of isolated outlets
The 12 sockets The rear panel wiring is strategically divided and isolated to prevent cross-contamination between the various components of your system. This electrical organization is crucial because amplifiers and source devices have very different power consumption patterns and can cause interference if they share the same unfiltered line.Intelligent power allocation ensures maximum dynamic performance for every type of connected device. The conditioner reserves specific connections that guarantee the precise current flow required by each link in your sound chain, without compressing dynamic transients.
The output configuration is distributed as follows:
- 8 outlets with linear filtering optimized for constant current sources
- 4 high-current outlets dedicated to variable consumption components
- Total maximum system capacity 15 Amps RMS
By using high-current connections for your power amplifiers, you ensure that the bass retains all its impact. At the same time, the filtered jacks protect and purify the delicate signal from the preamps and DACs, resulting in a pristine soundstage.

Wiring reference PQ-715
Power from the wall is supplied via a detachable power cable. 2 meters, the model AudioQuest PQ-715This cable incorporates industry-leading noise dissipation technologies. It's not just an accessory, but a critical component designed to prevent the first connection segment from acting as an antenna that picks up external radio frequencies.The cable construction employs concentric semi-solid conductors of long grain copper (LGC) which minimize magnetic distortion. Furthermore, it is equipped with a practical flat plug that facilitates installation in tight spaces, flush against the wall or behind heavy furniture, optimizing space management in the home environment.
This cable stands out for integrating the following exclusive innovations:
- Technology ZERO-Tech to transmit current transients without audible compression
- Technology RF/ND-Tech for unprecedented electromagnetic noise dissipation
- Robust transmission capacity 15 amps at 120 V
Thanks to this level of demand right from the plug, the power conditioner receives a much cleaner base power supply, exponentially enhancing the effect of the internal filtering and guaranteeing the best performance of your entire high-fidelity audio system.

Designer and rack mounting
The heavy-duty metal chassis ensures the equipment's durability and provides excellent additional shielding against external electromagnetic interference. With dimensions of 432 mm wide, 86 mm high and 340 mm deepIts standard format allows it to be discreetly placed in any audio furniture, adapting to the aesthetics of conventional receivers and amplifiers.Integration into technical furniture is guaranteed, as its size is exactly equivalent to a component of 2 rack units (2RU)The set includes the corresponding fixing ears, facilitating its screw-on installation in professional cabinets or dedicated home cinema rooms in a safe and permanent manner.
The most relevant physical aspects of this conditioner include:
- Robust body with a net weight of 4,9 kg which provides great stability
- Indicators Status LED front panels for monitoring operation
- Total height of 89 mm when counting the pre-installed insulation feet
Whether you choose to place this surge suppressor on a visible shelf or conceal it in a machine room, its robust construction and mounting hardware ensure a clean installation. The unit remains easily accessible for managing the cabling of up to 12 components simultaneously in a neat and professional manner.
