Some help here please.
Marantz AV7702mkII….DC OUT jacks bad
AV7702mkII, new not refurbished, now 11 months old. DC OUT jack #1
now turns the amp (McIntosh MC205, 5 channel) on then immediately turns off. I switched to jack #2
and after 3 weeks decided to ship it to Marantz to repair #1
AV7702mkII manual says:
When a device with DC IN jack is connected, the connected device’s power on/standby can be controlled through lined operation to this unit. The DC OUT jack outputs a maximum 12 V DC/150 mA electrical signal. Use a monaural mini-plug cable for connecting the DC OUT jack. Do not use a stereo mini-plug cable.
MC205 manual says:
The MC205’s Power Control Inputs receive On/Off signals of +5 volts. An additional connection is for controlling the illumination of the MC205 Power Output Meters. The 1/8 inch stereo mini phone plug connects to a McIntosh A/V Control Center Power Control Output.
I was using a 6 foot stereo mini-plug to connect the AV7702mkII to MC205, in order to illuminate the meters.
I’m wondering if the problem is using a stereo pin in the AV7702mkII.
Or the output 12 v DC/150 mA signal Marantz and the input +5 volts of the McIntosh?
If the problem is caused by the stereo plug, I can use a mono and unfortunately loose the McIntosh illumination.
Maybe something is wrong with the McIntosh?
Repair shop just told me, Jack #1
is bad and Jack #2
looks like it's going bad too.
And thoughts on what is happening?
