  • Page 18 The setup strategy is dependent on the PA-BUSS Amplifier string. The maximum PA-BUSS audio Signal Output is 0dBm. All Tech Works Amplifiers, provide maximum rated output with a 0dBm input. Therefore all controls, on each Block, and Amplifier may be considered an Attenuator (Below the maximum output level).
  • Page 19 This reduces the number of Microphones & Speakers required in 'large' systems. This also reduces background noise in the system. Tech Works CI-Buss Products provide additional Feedback Prevention techniques: Selective Gain Reduction, “Ducking”, can be very effective. When a Microphone is keyed, the associated speaker can have its level automatically reduced.
