Connections and Cables Balanced vs. Unbalanced Audio Connections Balanced signal connections are preferred in pro audio applications because of their improved immunity to induced hum and noise. A properly shielded and wired balanced input stage on any audio product will reject most unwanted noise (RFI, EMI) picked up by the cable, as well as minimize ground loop problems. Therefore it is always advantageous to use balanced connections when running signal more than ten or fifteen feet, althoug

Typical Applications (cont.) Compression for Feedback Control Procedure: 1. Set up the CLG-600 unit's controls as follows: a. Output level control to -20dB. b. Input Gain control to 0dB. c. Threshold control to -30dB. d. Ratio control to infinity ( ) e. Attack time to 5mS. f. Release time to 1 sec. 2. Adjust equalizer controls to a flat setting, and if the equalizer has an overall volume control, boost it by 10 to 15 dB. 3. Open up several microphone input channels to a

Typical Applications (cont.) Broadcasting Compression has long been used as a tool to make an audio signal appear louder. A good example is in broadcasting, where competing stations with identical transmitters and power attempt to sound louder than each other. Since they are all restricted with respect to maximum audio level (modulation), their best tactic is to squeeze the dynamic range of their programs to just a few dB. The audio output level of the station virtually never changes, and th

Troubleshooting Tips Things to remember Unshielded cables, improperly wired connectors, and cables with broken strands of wire are very common problems. Use quality cables with quality, correctly wired connectors. When using heavy compression, background noise is noticeable during quiet sections of the program as defined in the section on compression, quiet program material is effectively made louder while loud peaks are made quieter. When the program source is thus raised in volume, its nois
