Yes, but there is no applicable standard. I advise clients to include in the user instructions a warning to keep magnetic media (floppy discs, cassettes, credit cards etc.) and VDUs at least 30 cm from the loudspeaker (unless it has a closed-field driver). > I know that higher power pro audio systems are not allowed >to use 'binder post' connections and that they tend to use bicon connectors >in Europe, but I don't know what standard and/or directive is requiring >this. EN60065 and the Low Voltage Directive. Do we use the actual power output, e.g. 3 W, or the PMPO, e.g. 400 W to calculate the output voltage, to see if we need to use the 'safe' type of connector? (;-) Let's see; 400 W in 8 ohms is 56.6 V - yes, we need the safe connector! -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Eat mink and be dreary! ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
