- Page 2 Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical shock, short-circuiting, damages, fire or other hazards. These precautions include the following: Power supply/Power cord/Grounding Use only floated test equipment. Oscilloscopes, PCs, signal generators, voltmeters, etc. must be connected through a three-to-two-prong adapter to avoid ground loops and other conditions that may damage the amplifier.
- Page 3 Operation Your DDC 500 Series Amplifier is factory programmed to 0dB Output Gain; please take your precautions before applying any audio signal to the input. Read the Amplifier specifications (page 22) before connecting loudspeaker loads. Do not operate the LF, MF and/or HF amplifier sections (depending on the model) to Max Power when all the channels are set to flat response without crossover filters.
