Question about Harman Kardon Audio Players & Recorders
When running the tone test there is a very faint trace of sound from the R surround. I boosted the output to +10 dB (on the R surround) and there was a slightly louder but distorted tone but it really couldn't be heard unless you had your ear right against the speaker. This was the same situation for every mode and source.
Possibly unrelated to this is an audible hum from the unit when it is first turned on for about a minute. I presume something is warming up, but I imagine that either way, the hum shouldn't be there.
The amp that runs the R surround speaker is or has went out in the main amp! also switch speakers around to make sure that one is not blown!

IMPORTANT: When connecting two pairs of speakers, determine the impedance of each pair
by looking on the back of the speakers, in your owner's manual, or by contacting your dealer or manufacturer.
You can listen to two pairs of speakers at the same time ONLY if the impedance of EACH speaker is NOT LESS THAN 8 Ohms.
WARNING: Do not play sets of speakers simultaneously except as recommended above.
Amplifier may overheat.
