QUADRAL - AURUM A10S Integated Amplifier
QUADRAL - AURUM A10 S, Stereo Integrated Amplifier.
AURUM A10S
top-of-the-line amplifier
M A5
The AURUM A10S is our high-end streaming full-amplifier – handmade in Germany. It is based on its excellent brother A8. We outbid the whole spectrum of technical and scientific knowledge of circuit technology with our integrated high-end amplifier so you can enjoy an extraordinary level of listening pleasure.
The ability for us to create a powerful reference amplifier that delivers such fabulous dynamics and both a rangy and finely detailed sound reproduction is paramount to our beliefs and objectives.
Level of protection
•Class-AB output stage for low distortion sound and great sonority.
• Undisturbed operation at the highest level through individually decoupled sections.
• Separate power supplies for standby power and digital and analogue modules.
• The wideband filter clears external balanced disturbances from the power grid and unbalanced disturbances from housing and „ground wire“.
Input switching:
• High quality, encapsulated signal relay and hard-gilded contacts for optimum signal transmission.
• Almost wear-free relay for an exceptional long lifetime.
Input Level:
• Particularly low distortion and low-noise due to BI-FET operational amplifiers for the widest frequency range and clear increased dynamics in music reproduction.
• Low-noise operational amplifiers from Analog Devices for a sensitive input stage.
Signal Forwarding:
• Efficient signal transmission with minimized distortion.
• Optimized module architecture for short signal paths.
• High-quality polypropylene film capacitors made in Germany.
• Extreme interference suppression and loss-free signal forwarding through SMD technology (an innovative technology for the production of assemblies).
Real double-mono-construction:
• Separate power supply for each channel, individual signal processing and individual signal amplification for more strength, dynamics and performance reserves.
• Two separately operated, stray power supplies, a transformer and a rectifier for a finely-resolving and stable sound.
• balanced inputs (XLR) for optimal signal transmission. This professional type of connection allows signal transmission with a ground wire exclusively used for shielding and on which itself no signal flow takes place.
Pre-amplifier and full-amplifier:
• Professional, precise and logarithmic working volume adjustment as in the studio with real 1 dB steps.
• Exactly synchronized volume control of the audio channels.
Streaming:
• Streaming service integration with your own AURUM app for (Android / iOS).
• Supported services: Tidal, Airable Radio, Airable Podcasts.
• Wi-Fi 802.11 b/g/n
• Ethernet 10/100 Mbit/s
• LAN RJ45
• USB A for USB storage media
• Supported formats: MP3, AAC, WAV, Flac, WMA, LPCM, ALAC.
