Volume controls

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.
