+ 5/- 10% of the nominal rated voltage. Electromagnetic Interference (EMI) Considerable care has been taken in the design of the CA200 to minimize its susceptibility to radio frequency interference and other forms of EMI. Choice of materials, physical layout, grounding prac-... - Page 6 Physical location and cable “dress” can be an important factor in minimizing hum pickup. The installation should situate the CA200 well away from sources (CD player, tuner, etc.) and power (ac mains) cords should be dressed to remain at least 4" (100mm) away from input/output cables.
- Page 7 We recommend the use of an amplifier with an in- put impedance of 20k ohms or higher. The Pre Out is phase cor- rect. See the section on “Getting the most out of your CA200" for an explanation.

This will be the case if the number of phase inver- sions is even (or zero). The CA200 is phase inverting. If your system has an odd number of inversions, (for example, if the CA200 is the only phase inverting unit in the chain) then you must add one phase inversion. - Page 12 The warm up period can be expected to last about half an hour.
