SOURCE: Audio glitch on Marantz SR-19

It's probably not heat due to the Marantz' large frame and heat-synchs.
This could simply be a mismatch of impedance. The amp is 120w per channel, so make sure the speakers can handle this. Check the impedance (ohms) of the speakers and the amp as well. Clipping can be caused by overpowering the speakers, which could damage the speakers in the long-run.
If this is only from 1 source- (i.e.- Blu-ray player or cable) then it could be digital clipping.. This Marantz can decode 96kHz PCM or normal Dolby Digital & DTS. If this is a Blu-ray it may be streaming 192kHz PCM... (but most likely the Marantz will not even attempt to play that audio)
I hope this helps.

SOURCE: my marantz SR 7400 suddenly shuts down or goes

Most likely you have a speaker short, you need to check the ohms on each speaker disconnected from receiver if they are 8 ohms they should be close to that on the meter no more than a 1 and half ohm varience to what the speaker ohms says on the back. If they are ok you need to disconnect speaker wire from receiver and check for a short in the wire by connecting ohm meter leads to ends of the speaker wire you should get no reading if the wire is good. If this is all good you have a bad output transister in your receiver, but i dout this is the case because these transisters normally short to ground and blow a fuse. Hope you solve your problem good luck

Tip

Marantz SR-7200 reset


This was documented on the Marantz website briefly a year ago and is no longer available. My SR-7200 develops "click/pop" problems and a reset cures it of these issues.

While powered "off," on the front panel, press: A/D + FP +Dimmer (3 buttons) and power the unit on.

This reverts to original (out of box) settings. You then must reprogram input sources, speaker setup, levels and radio stations.

Check to see if your transformer is open or not. Use a DVM and check the ohms to see if it is shorted.

Hello i have a marantz receiver sr7400 fuse


Unplug the unit. Carefully unscrew the screws for the case. Probably 4 screws, 2 on each side of the unit. Remove the cover. Look for the fuses, and replace with exact same type/specs of the faulty fuse. If the fuse, is on a printed circuit board, be careful dislodging the fuse. Hope this helps.
