- Page 4 Please read this manual fully before installing or operating the Equaliser. PRECAUTIONS The T L Audio EQ2 Parametric Valve Equaliser requires very little installation, but like all electrical equipment, care must be taken to ensure reliable, safe operation. The following points should always be observed:...
- Page 5 INSTALLATION AC Mains Supply. The equaliser is fitted with an internationally approved 3 pin IEC connector. A mating socket with power cord and mains plug is supplied. All mains wiring should be performed by a qualified electrician with all power switched off, and the earth connection must be used.
- Page 6 When using unbalanced signals, the signal ground may be obtained by linking pins 1 and 3 in the mating XLR connector. Good quality screened cable should be used, particularly for microphone or low level sources, to prevent hum or noise pickup. Unbalanced Line Inputs.
- Page 7 - Pin 2 = Signal Phase (“+” or “hot”), - Pin 3 = Signal Non-Phase (“-” or “cold”). If an unbalanced output is required, pins 1 and 3 should both be connected to ground. Nominal Output Level. A switch on the rear panel allows the output to be matched to equipment at a nominal operating level of +4dBu or -10dBu.
- Page 10 OPERATION. Front Panel. The front panel controls are identified in fig.3 Input Stage. Ensure that the correct input connector, mic or line, is being used and that the front panel switch is set to the appropriate position. Note that both mic and line inputs may be connected at the same time, but only one is selected.
- Page 11 Stereo Switch. Most two channel equalisers require the time consuming and inaccurate practice of attempting to match settings on two sets of controls. The EQ2 provides a simple and quick means of ganging the controls into a full stereo equaliser.
