DACT CT3-5-4 PCB HIGH END INPUT SELECTOR

 121.06

  • Low noise, non-inductive, metal film SMD resistor network
  • Compact design
  • Entire signal path gold plated
  • Shorter signal path than conventional attenuators with leaded resistors
  • Reduced inductance and stray capacitance
  • Improved sonic quality
  • Improved accuracy – 0.05dB tracking and 0.05dB attenuation accuracy
  • Improved reliability
  • Increased bandwidth
  • Reduced distortion, less than 0.0001%

Description

CT3 is a high quality Audio Selector Switch.
It is based on the same high precision, Swiss made switching mechanism as the DACT CT2 audio attenuators.
CT3 is a non-shorting type of switch making sure neither of the input sources will be short-circuiting each other when the switch is operated.
CT3-5-4/PCB switches two channels simultaneously. For both channels it switches signal AND ground. This is an effective way to minimize the risk of creating ground loops.
In the same way CT3-5-8/wire switches 8 poles.
FEATURES TYPICAL APPLICATIONS
  • 2/4/8-pole switches 2/4/8 channels simultaneously
  • Gold plated contacts for long lifetime even in hot and humid environments
  • High reliability
  • Matches perfectly with DACT CT2 audio attenuators
  • Mechanically “programmable” for 1 to 3 or 5 or 6 postions
  • Input selector in Do-It-Yourself Hi-Fi / audio projects
  • Input selector switch in active or passive preamplifiers
  • Selector switch in professional audio equipment
  • Switch for long lifetime applications
  • Test equipment selector switch

 

Notes
1 Exposure to maximum rating conditions for extended periods of time may affect device reliability
2 Rms voltage, 50 Hz, 60% relative humidity, applied for 1 minute.
3 One cycle is defined as a full rotation from one end stop to the other and return.
4 Measured with 500 VDC for 1 minute.
ANTISTATIC CHARGES

To avoid noises from antistatic charges we suggest that one of the following two precautions is taken:

  1. The CT3 is mounted with electrical connection between its click-house and the equipment chassis.
  2. A 1 MOhm resistor is connected between the CT3 click-house and equipment ground.
