New from Danish Audio ConnecT (DACT) is their CT2-10k-1 ultra-fine 0.5dB
stepped attenuator. This is excellent for individual channel control in multi-channel systems, active crossovers, etc.
DACT's attenuators employ a resistor network using Surface Mount Device
(SMD) for ultra-short signal path plus verylow series inductance and stray capacitance. The CT2 series of audio volume controls are high quality stepped
24-position attenuators.
They are designed for maximum sonic quality, accuracy and reliability. This
makes them equally suited for audiophile applications and for professional applications. For many years DACT has been offering extremely high quality master
volume controls with 60dB attenuation range (1, 2, 4, 6, 8 decks).
Their series resistor networks consist of 23 non-inductive, low noise, SMD metal film resistors. The layout of the PC boards and the choice of SMD resistors
reduce the signal path to a minimum length (typical five times shorter than
conventional stepped attenuator designs with leaded resistors).
The PCB design combined with the special resistors also account for the very
low series inductance and the very low stray capacitance. The result is a bandwidth beyond even the most demanding audiophiles’ requirements.
Special care taken to ensure the durability of CT2, therefore all contacts and PCB traces are gold plated to prevent any corrosion. Meanwhile the rotary
switch itself is a gold plated high precision switch manufactured in Switzerland.
Many high-end audio manufacturers and people in the DIY community enjoy
the benefits of using these stepped attenuators in their designs.
They are also used by those who tweak equipment to achieve higher quality music reproduction. High-end sound and specifications Compact design easy
to mount in most existing audio amplifiers as DIY upgrade. Audio volume controls with very accurate attenuation and tracking (0.05dB).
