The Ideal Volume Control for Music Lover

CT1 STEPPED ATTENUATOR
DESCRIPTION:
The Danish Audio connect's(DACT) CT1 is a high quality stepped 24-position attenuator or volume control for high quality amplifiers and other equipment that you can ever owned nowadays.

It is supplied in a two channel (stereo) version with two individual Printed Circuit Boards mounted on a two wafer rotary switch. The series resistor network consists of 23 non-inductive low noise SMD metal film resistors.
The layout of the PC Boards and the choice of resistors has reduced the signal path to a minimum length (Patent is Pending).

All contacts and PC Board traces are gold plated to ensure long-term reliability.
The rotary switch is a gold plated high precision switch manufactured in Switzerland and is a make-before-break type.
The CTl is designed for maximum sound quality, accuracy and reliability.
Standard impedance in stereo are 10K, 20K, 50K, 100K and 250K ohm,  ohmic law type A.
Mono type impedance are 10K, 100K & 250K. Ohmic law type A.
Other custom designed versions are offered.
