Adding 2 extra channels to pair a MC7205 with a MX119 pre/pro
I'd like to move my MC7205 into my theater and pair it with my MX-119, but I'll need an extra 2 channels of power to run the 7.1 feature. Is adding another stereo amp to the Mx-119 pretty straightforward, or is there something I should be mindful of? Can I connect the MC7205 to the MX-119 using the serial cable and then use RCAs to connect the other two channels, or will that mess with something the wrong way?
Re: Adding 2 extra channels to pair a MC7205 with a MX119...
Yes, you can connect the MX119 'Multi-Amp' output connection to the MC7205 using a 'Parallel' 25-pin cable. It will send Front_L/R/Center/Surround_L/R signals (5 total) to the MC7205, then use a separate pair of RCAs cable to connect the 2 back-surround signals to another 2-channel amp and you are all set.

Did you try to switch the loudspeakers? Before changing anything always lover the volume and switch off the amplifier. Assuming you tested already different inputs, you can be sure no cable from signal source is out or defect. (or did you nit check that first?). When the amp is switched off, disconnect the speakers and switch left to right and right to the left output.. If the other speaker is quiet now, you are sure it is in the amp. Still his can be anything. You can check the connections between the pre and main amplifier on the back side. When you have an extra set of interlink cables, perhaps you can cross the in and output there too. Take care every time you change something, lower the voltage and switch off the amplifier. Sudden clicks when switching on or changing anything can damage the amp and or the speakers.
Perhaps when you checked this you can locate where the problem is? Speaker, speaker cable, power amp, pre amp, (only a part of the pre amp.
First off before you do it is a specific bulb custom sized. I cannot stress enough how important it is to use the correct bulbs for this application. If you go the cheapy way it will COST in the end. There is a reason for it. I recently had one someone brought in that used the incorrect bulbs and burned the blue to a horrible brown and blue away from the face as well as melted the face a little. Spend the extra and get the bulbs from McIntosh It was a three hundred dollar repair job. You will save by getting the correct bulbs and doing it yourself. I hope this helps pointing the way to save lots of later frustration.
I work with these amplifiers every day and i can tell you that they not made with quietness in mind.
They are mainly used in a club/disco environment and often mounted in a equipment rack hidden in a closet.
Excellent/tough amplifiers if you want power and clean sound ,but
You may find their noise level uncomfortable in a living room.
Hope this help Merry Christmas
These units are capacitor coupled between stages. It sound to me like one or more of those caps are defective. There is an extra stage of amplification for the Phono inputs. Check the phono pre-amp section for defective caps.
It sounds like you want to use the external amp rather than the internal one. If that is the case, just connect the output of the EQ to the input of the external amp. All you are doing is inserting the EQ between the amp stages now. Using the mx-1 rather than the internal amp is no different.
what to remember is pre-amp is before the amplifier then the amplifier to the speakers, go this route, Tuner for radio? from the radio tuner out go to the pre-amp tuner input, then from the pre-amp OUT go to the AMPLIFIER IN, tuner, cd, dvd, tv, any source, if you are using a 2 channel amp and pre-amp this is relatively easy, a little more detailed for multi-channel pre-amps and amps but follow the same path, sound source signal ie. tuner to pre-amp, pre-amp out to amplifier and speaker hookup to amp channels,
HI SIR .THAT IS NOT BIG PROBLEM.ALL YOU HAVE TO DO MAKE SURE THAT YOUR PRE HAVE THE FLL.1 PROPERLLY EARTHED(THE GROUND FROM YOUR AMP ALSO GOES TO THE PRE )2 ASK YOUR ELECTRONIC MECHENIC TO CHECK IF THER'S NO BROKEN GROUND ON THE BOARD INSIDE.
