I love my Marantz 2385 receiver, with my Bose 901 series VI speakers with the equalizer. The sounds are absolutely amazing. One of my most treasured possessions.



re: 2385

Does anyone have an owner's manual? Not a brochure or repair manual, but one that describes all the knobs and switches etc

Marantz 2385 receiver

I was asked to 'repair' a friend's Marantz 2385. He just bought it from someone who said it works perfectly but he won't answer his phone when my friend tries to contact him. Apparently both peak indicators come on when he's switched to FM radio and he's afraid that this will blow his speakers. I checked it out [I am unfamiliar with this model] and the leds do come on at about 30 or more percent of the volume control. When I input a sine wave signal into the auxiliary jacks, the outputs are clean up to maximum level which is almost two hundred watts per channel. I think it's operating normally. I don't have an owner's manual. What do you think? Thank you. Len.

re: Marantz 2385 receiver

Yes normal, it is just a switching the input, to the meters, from the FM out. Only if you hear a thump sound, come out of the speakers, can it possibly hurt them. That is also why there is a turn on delay speaker hook up relay built in. This prevents turn on thump from hitting speakers. If thump is to loud, relay will cut out speakers and protect them, anyway.

It's my new baby. I love the service manual but i have 2 questions:

1- Where i can find the user manual?
2- What type of loudspeakers it have?

Thanks to everyone and to the HFE for the service manual!

PS: sory for my porr english, i'm Brazilian!



I just got a 2385 and it came with a pair of marantz DS-900 Speakers. They seem to be the speakers you would have bought back then with the 2385. I am now in the process of fixing some problems with both and havent heard the sound yet. But the person who gave them to me happened to be the original buyer and he said they served him fine for a few decades.
unfortunately I have no manual either.

Marantz 2385 Manual

Dear Sir or Madame:

Thank you very much for making the repair manual available for this receiver. I bought it new at Robinson Barracks in Zuffenhausen, Germany back in 1978 and according to current Marantz company techs, it still offers the best in stereo high fidelity. You would have thought that by now there would have been vast improvements in sound quality, but apparently not. This manual will enable me to continue enjoying my antique technology for many years to come! Thank you very much once again.

PS: Does anyone have a repair manual for a Marantz DR 4050 CD burner or a manual for Pioneer CS911A speakers?

service info

I greatly appreciate the info. I found one of these behemoths at curb-side awaiting garbage pick-up (can you believe someone tossing one of these??) It is basically in good shape, but needs the TLC that this manual will help provide!
Thanks again,
