Sounds like a bad speaker. Do you have more than one speaker hooked up to a single output?

SOURCE: Marantz SR5000 Protect mode

The Marantz SR5000 and others of it's make, design type, and year group are prone to this problem. Many such units can be reset by pressing a sequence of three buttons with sporadic results... the SR5000; however, does not provide any such option. If the "Auto protect" mode comes "on" then you know it's not a simple power supply "fuse" problem that can be fixed for a dollar by opening the case and replacing the glass fuse with one of the same rating value that is stenciled on to the power supply circuit board. (Easier than trying to read the old fuse.) If you can get the schematics and know a bit about replacing electronics parts using a low-power soldering iron, then you might want to take a shot at fixing it; otherwise, it's time for recycling. (Tip: Look for discolouration on a part on a circuit board first, this indicates overheating and a possible short. Then trace the schematic circuit for the "Auto Protect" circuit to diagnose which integrated circuits is at fault.) Typically, it costs more to fix it in a commercial shop than it's worth as someone has to pay the cost of benchtime diagnostics... the repair part is fast once the faulty parts are discovered. There are free sources on-line of the service guide for this receiver; however, downloading the plethora of rar files to assemble a complete manual is a challenge.

SOURCE: Problem with Marantz SR5500 Receiver

Sounds like you have an issue with your electrical circuit. Your receiver could be receiving spikes of current from the electrical wiring in your house.

Review your current electrical situation. Keep in mind that certain outlets are on the same circuit and that running multiple, high-wattage devices on the same circuit can cause issues with some of those devices. Especially when it comes to turning devices on and off.

Many devices take a sudden, rapid charge to power their circuitry the moment you turn the device on. Home audio and HVAC systems are particularly notorious for doing this. Other devices on the same circuit can sometimes suffer influxes of power flow and may either turn off or go into standby mode to protect themselves from the resulting surges.

I've lost audio systems that way... I lived in an apartment building that has wiring most likely dating back into the 40's. I once turned on a space heater on it's max 1500 watt setting and blew my Logitech Z-680 speakers. (The "BOOM" sound that emitted from my subwoofer was AMAZING. I had just blown an amp circuit. It literally exploded inside of the subwoofer. Took pics and everything.)

If you have the means to do so... You might consider re-wiring your electrical circuit. Take into consideration where you're going to run certain devices and wire the system accordingly.

In the meantime, you would want to be sure to buy a HIGH-QUALITY surge protector for the audio system. Spend a few bucks and get a GOOD one with a good warranty on it. Don't use those cheapy ones that we only really use to split the outlet. NOTHING under 1,000 joules.

My receiver sometimes locks itself like that, though. If we have a power outage or the unit is unplugged suddenly, it will keep itself in standby mode until you unplug it, press the power button a few times to discharge any current left in the capacitors and plug it back in normally. Only then will it turn on again.

Let me know what you come up with.

SOURCE: Input signals Marantz SR4003

There are four digital connectors on the back of the unit: 2 optical and 2 coaxial. They are marked a s 1 2 3 4. 1 and 2 are optical, 3 and 4 - coaxial. Also you have front optical connector marked as F.
You can connect 5 digital sources to your receiver. For example, connect your DVD to input 2 (optical) by optical cable and connect your DSS to input 3 by coaxial cable. Assign DVD to digital 2 and DSS to digital 3 in input setup menu.

How do you connect an ipod/ipad to the Marantz sr4001


Anything that has a headphone output can be adapted to feed an RCA cable pair for standard stereo to any audio device with a standard RCA input. Get a cable like the one described here:
