Relax on the balanced output guys! Posted by Chuck Swindoll, Jr. [IP: 216.60.50.43] on January 29, 1999 at 14:50:10: Balanced outputs were invented and used by the pro market (exclusively, mind you, until recently) to keep noise out of the microphone signal cables. Balanced lines are also used to allow phantom power (typically 48 volts) to be sent to condenser mics to power their plates, but at the same time not to allow the voltage to blow-up dynamic microphones. Balanced lines are also needed and used to this day in long snakes (cables that have lots and lots of signal lines in them) that are sent from the performance stage to the house/monitor consoles. These snakes will carry both line level (+4dB or –10dB) and mic level (-60dB) signals in them. Balanced signals are also needed and used on all microphone outputs in any recording studio/facility as the mic cable (which carries the mic signal) is very susceptible to outside interference. Why there is such a big fuss for the Lexicon to have balanced (LINE LEVEL -NOT MIC LEVEL- MIND YOU) outputs is beyond me. Also, if another pre/pro has them, that unit is viewed to be so much better. (interesting thought…) Why on earth a line level signal that is run for maybe 25 feet (though almost always less, as the amps are very close to the location of the pre/pro in most homes) needs to be balanced is beyond understanding. Seems as though a number of businessmen out there wanted to put a neat little cool add-on to their unit to make it look so much better has worked. I hate to tell you this, but they are now laughing their way to the bank, since people seem to think the unit is so much better sounding (and built) if it has these "special-cool" little outputs on its back. Further, most of the consuming public do not even understand what a balanced signal is, why it was invented, and why they would even need it - which they don't in the first place! Come on guys! Let the balanced issue go. Chuck Jr.
