Kenwood Basic M2A Shuts Down at Higher Volume

[OnThePike]

Hello all,

The subject line pretty-much says it all. At higher volume, my trusty old Kenwood Basic M2A appears to enter standby mode, cutting off the output and flashing the power indicator.

Here's a list of what's running:

Kenwood Basic M2A Power Amp
Kenwood Basic C2 Control Amp
Kenwood GE-1100 Equalizer
Gemini CS-02 Mixer
Gemini iTrax iPod Mixer
Cerwin-Vega CLS-215 Speakers
Technics SL1200 MKII (1983 originals)

The CV's are hard-wired using about 30-feet lengths of 14g zip cord, properly phased and not touching anything but their intended connectors.

I'm using the mixer output gain as my master volume, with the M2A output controls set to 7 each and the Basic C2 output around 12:00. The mixer input gain is set to about 80%. The mixer channel output varies between sources; usually between 5 and 9 (with 10 being maximum).

Any ideas as to exactly what is causing the M2A to drop out? Any suggestions/comments welcome.

Thanks,

Jeff
