Yes, it can possibly damage the 4802. You are outputting preamplified signal into a preamplifier, as John said. The input voltage from a preamp is higher than that from a decoder or SACD player, which is what the 4802 ext-in is for. It is not designed to take input from a preamp.

I used my M80s with a 75WPC Harman/Kardon receiver for years. Worth a shot, at least.

Hi JBGood,

I got your private message but I thought I'd answer it here for the benefit of other forum readers.
Part of the problem is that you are not specific enough in your use of terms, so we're somewhat confused.
You have two receivers (not integrated amps) and you want to use the pre-outs on one to feed the line-level inputs on the other receiver.
Further to the comments of JohnK and KenC, you can only do this if the inputs are labeled "amp in", which would feed the pre-out input signal to the amplifier section of the other receiver and bypass that receiver's preamp section. You would then use the volume control of the pre-out receiver to control the volume because the volume control is in the pre-amp section of the receiver and controls the pre-out signal level to the amp in the other receiver.

However, if you mean feeding the pre-out signal into a line-input on the other receiver, and into its preamp, NO, don't do this for the reasons mentioned by JohnK and Ken.

Hope that clears things up.

Regards,
Alan

Hi,
Three-channel power amps will run cooler than a five-channel amp, so I'd get the 3-channel amp for the front three channels now.

By the way, despite my hangover referred to in the PM I sent you, I did go through the Denon manual, and Ken/JohnK are correct. The Denon's amp inputs are labeled "Ext. In" on the back panel and on the remote, and seem intended for the low-level analog outputs of an external SACD decoder or the like, which, although the manual is unclear, I suspect those feed the preamp section but bypass all the Denon's Dolby/surround decoders. That's the way my old H/K receiver's external analog decoder inputs are wired, which give you volume control of signals from the SACD player.

Denon receivers, even the cheapest ones, will drive 4-ohm loads without shut-down, unless of course you are trying for extremely high sound level playback and overload the Denon's output capabilities. Just curious why you're not using the Denon to drive your system?

Alan

Alan,

1) the mrx is not very good on 4ohm load I have m80's, vp180 + 2 pairs qs8's and this amp is rated @75 watt on 5 channels..but has the hdmi 3d & arc correction + new processing

2) the denon 150@4ohm each channel..real sweet but the denon has no hdmi & manual correction + 10 year old precessing

I don't neeed the 9.2 precessing or the extra features like hd radio .. I mainly use the setup in HT room watch films, 3d, tv + computer & music

JBG, according to various posts here, the MRX500 is capable of handling 4 ohm loads.
