VOLUME CONTROLS WITHOUT COMPROMISE FROM
DANISH AUDIO CONNECT: CT1 & CT2
Dact audio attenuators are arguably the finest volume controls available today. Gold plated contacts/wipers, non-inductive surface mounted resistors configured on the shortest imaginable signal path linked by gold plated tracks result in absolute sonic precision. The specifications to follow speak for themselves: -
Resistance tolerance: 0.1%
Attenuation accuracy: 0.05dB
Channel balance: 0.05dB
Contact resistance: 0.01 Ohm
Rotational angle: 300o +/-5o
Capacity between contacts: 0.001nF
Series inductance (10k Ohms signal to ground): 0.0002mH
Attenuation levels/source impedance = 0 Ohms: 0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,
30,34,38,42,46,50,60,
Current ratings: 2 Amps at 2 Volts
0.6 Amps at 24 Volts
0.4 Amps at 42 Volts
Maximum power dissipation of one SMD: CT1 = 125mW
CT2 = 100mW
Operating temperature: -25oC - +85oC
Switching angle: 15o
Distortion: less than 0.0001%
DACT CT3 INPUT SELECTOR SWITCH
The CT3 utilises the same Swiss-made precision mechanism as the renowned CT1 and CT2 attenuator volume controls. This guarantees highest contact pressure and therefore the lowest resistance loss. All switch/wiper contacts are gold plated. Inadvertant shorts either to ground as well as signal sources are totally avoided as both signal path and ground are simultaneously switched, also avoiding unwanted ground loops. The CT3 selector switch offers the selection of 5 stereo inputs.
Gold plating: Layer-thickness of contacts = 8um
Gold plating: Layer-thickness of wipers - 3um
Switching current ratings:
2 Amps at 2 Volts
0.6 Amps at 24 Volts
0.4 Amps at 42 Volts
Operating temp: -25oC - +70oC
Switching angle: 15o
Mechanical life: 25000 operations
Switch operation force: 1.5Ncm
High quality knobs machined from solid stainless steel are available for all DACT switch/attenuators.
Diameter: 25mm
Height: 25mm
Inside diameter: 6mm
All DACT products are presented mounted within a transparent box.
