Master Active Cable
Real-time phase correction and noise reduction
Pursuit of Ultimate Detail
Through MAC, you can feel the lowest noise, the strongest dynamics and the most complete information.
Frequency & Space
Layers and trajectories of low and ultra-low frequencies, spatial reverberation and sense of air, and a silent background blackness.
Imaging & Body
Clear sound lines and contours, smooth lines, high cohesion of the audio image, and a precise, distinct sense of solidity.
Tone & Texture
Distinct strength and weakness, a transparent and sweet tone, and soft texture — a full range of sound-quality performance.
Refined Audio Performance
All this comes from Telos' new era of reference-level technology integration.
As it delivers power, MAC detects power-phase drift in real time and corrects it in reverse, while suppressing high-frequency noise and power surges to push the noise floor to its lowest.
With the noise pulled down, the faintest details once buried emerge — transient dynamics, soundstage layering, and the density and luster of tone are all reproduced more cleanly and stably.
Precision Acoustic & Power Control
Combining Telos's innovative technology with carefully selected components to comprehensively enhance stability and sound purity.
Aerospace Material
MAC is made of 6061 aerospace aluminum shell, with a multi-chip low-resonance chassis design, and equipped with Telos' exclusive Quantum resonance circuit inside, which can effectively suppress AC high-frequency noise and 50-60Hz frequency peak surges.
It is also equipped with passive PF, Danish Duelund customized capacitors, precision chip resistors, Telos conductor absolute directional manufacturing, graphene fuses, special solder formula, torque driver locking screws and other technologies.
Signal Correction
The MAC's shell is cut and formed from aerospace aluminum alloy, with 6-sided segmentation suppression technology, and extremely low chassis resonance to ensure the integrity of power transmission. Contains the exclusive Quantum phase correction module, PF correction circuit and high-frequency anti-noise circuit to improve power loop efficiency and suppress abnormal frequencies.
Continuously detects and compares the 60 Hz (or 50Hz) power supply, and sends out a reverse signal to couple the phase-misaligned power supply back to the sine wave waveform, with remarkable effect.
Direction
All components installed on the module comply with Telos's component selection rules, ensuring that resistors and non-polar capacitors are installed in one direction, and the audio and video are clear and embossed.
MAC's live, neutral and ground conductors are arranged in the same direction to optimize sound transmission.
Exclusive Craftsmanship
SMD circuit boards automatically produced by machines need to be compared repeatedly, and soldering of specific temperatures is added to different components, and the solder joints are manually strengthened to improve the integrity of AC power transmission and enhance sound performance.
Use an electronic torque screwdriver to lock the screw to ensure balanced force on the metal clip, improve wire impedance and conduction effects, and make the sound more balanced and smooth.
