Connecting Marantz Power amp to Marantz reciever

Please see my other answers covering the hookup of Marantz amps and preamps.

you need another reciever/amp to power that sub, because that denon reciever is designed for a powered sub,. if you have another old reciever/amp laying around, you can connect the sub out from the denon into an auxillary input of any old reciever/amp, (switched to that input) with speaker wires from old reciever/amp to the passive sub

Whatever video components you have, they should be, depending on inputs on TV, should be run to TV first. Recievers do have pass through ports but, are not the best way to achieve picture and sound. HDMI cables are great but you r reciever may not be able to transfer the video. What I suggest is taht you run your componenets, cable/sat box, DVD, etc. via HDMI, componenet, etc., to TV input, then, run audio out from TV, via(best) digital optical. You can use TV's menu to choose what you watch while, you only have the one input to reciever. Scan your recievers menu to make sure you have selected the proper mode(TV, Aux, Vid2, etc.).. If you run your video unit to TV with component cables, you will have to get your sound through separate cable(s). Component cables have graet video, but do not carry the sound.

Having looked at the manual it makes no mention of connecting a record player. So I think we can assume that there is no built in pre-amp for a magnetic cartridge. So you will need a pre-amp for that. You can use any RCA sockets on the device that are Left and Right audio in. A tape or CD player one will do the job, as long as they are analogue inputs.

The easiest way to think of your equipment is that in it's name is it's function; it "receives" signals. Then sends them out through the speakers. There are only a few exceptions in that there may additional outputs depending on the design...they may be for video or external amplifiers.
All of your components you would like to connect to the receiver will have output connections. Power off all components. Connect those to the labeled input on the receiver. If a component that you are connecting has both audio AND video such as a DVD player or TV, both connections must be made to the same input section to be able to use them simultaneously.

What brand of reciever are you using. Most pioneers have a floating signal ground and the shield of the input at the amp needs to be connected to chassi ground. Also if you had a previous amp failure and the power ground in your old amp opened the current to power the amp will flow through the signal ground of the reciever and burn the copper trace on the circuit board in the reciever. test this by connecting signal cable shield to car reciever chassi.

look on the back of the TV and there should be L/R audio outputs (white & red), connect this to a spare input of your amp via a connecting lead eg. AUX or any other input except PHONO.

hope this helps.

Dear driver800,
Don't you just love it when when someone who knows less than you do tries to answer your question? Why is it people who know little waste everyone's time with suggestions like "read the book"
On the back of your Marantz MR-235 you will find the RCA phono jacks marked Tape 1 Monitor Output these connect to the jacks labeled input on your EQ 140. The corresponding jacks labeled Tape 1 Monitor Input connect to the jacks labeled output on the EQ 140.

Hi spanky

Where to start :) I am excited thinking about them :p You got 2 totally cool pieces of classic vintage gear there in the C2 and the Marantz. I have a C2 preamp myself (gathering dust but wont sell it cos its excellent) and the marantz would be totally cool to have(but then I am a little biased towards 70's vintage marantz). They ruled the roost in HiFi amps throughout that decade.

Because they are both integrated amps, you could use them as standalone systems with a pair of speakers, and just plug your favourite gear into them. If you just wanted to run up a nice sounding HiFi, I would sell the kenwood gear and just keep the Marantz. The Kenwood kr1100 has the edge in power, so if it is grunt you are looking for use that. Because vintage sound is all about stereo, you only really need an integrated amp to get great results.

the specs are
# Kenwood Model Eleven G (KR-11000G) Receiver
120W per channel min RMS, both channels driven, at 8 ohms from 20 to 20.000 Hz with no more than 0.03% total harmonic distortion.
Dynamic power output 440W at 4 ohms
Power bandwidth 5 Hz to 70.000 HZ
Frequency response 5 Hz to 100.000 HZ -1.5dB
Signal to noise ratio 115dB

The marantz is a little lower in power at 75rms a channel, but will have the sonic edge in vintage sound over the kr1100. Look them up on ebay and you will find that they do have some value to collectors and people seeking nice tone. There is an 1152 for sale here for AU$900

Best bet is to fire up the 2 integrated amps,and see how they are going. Run them for several hours to be sure there is no strange noises and crackles. Then decide if you want power or finesse.

You could also run both amps from the C2 preamp by connecting to the Amp in connections to the rear of the integrated amps.

happy to talk to you more about it, hit me with a Fixya if my advice was helpful to you. I would keep the marantz, use that and sell the rest and buy some nice speakers:)

Hi jdwoomer

BEST WAY
Your amp has PreOut and Main In RCA connectors on the rear, you could make up an adaptor cable (or buy one) to split the post vol control signal at this point, and then use line level from here to drive the sub.

OR

Most powered subs have a speaker "high level" input, where the sub "sniffs" off signal from your speaker output. When setup like this the speakers and amp connect to the back of the Sub.

Either way, you can do it... Marantz were making nice gear back then... a collectable these days :) Any questions, I am here to help.
