Just bought this gorgeous receiver at a yard sale - they said it worked perfectly - it does everything great EXCEPT the left main speakers, front and rear are almost silent. The volume control works but it's 1/100th the volume it should be. All other speaker outputs work fine. I've got no documentation, but I do have tools, a dvm, and a soldering iron, so if somebody knows why this channel seems to be only preamped, or how to further t-shoot it, I might be able to fix it. Thanks in advance for your help!
The Denon 2500 was one of the best ProLogic receivers built, it was a work horse and very little ever went wrong with them.
To make sure you're only supposed to hear right & left speakers, press the Stereo button on the remote. Also recheck your speaker connections - this is the single most overlooked connection problem folks have.
Check the balance control to make sure it's in the center position
Make sure the Tape Monitor is not engaged.
Then, check to make sure that the Pre-Out, Main-In jumpers are connected properly on the rear panel.
If that is not the problem, try pressing the Tone Direct button on the remote (aka Tone Defeat on the front panel).
