Re: How do i bridge my mx 1500a because I dont have a...
Hi,
There's a switch on the rear, put this in bridge mode.
Connect you speaker (not under 4 Ohm) on the two red outputs.
Here's your manual. http://media.qscaudio.com/pdfs/mxusr.pdf
turn channel 2 volume down, connect 4 ohm minimum load to the two red binding posts of ch1 and ch2. use channel 1 input to drive the amplifier. dont gorget mx1500a is pin 3 positiveso speakers would be reverse polarity if you are using a diffrent amplifier to drive the other speakers.turn channel 2 volume down, connect 4 ohm minimum load to the two red binding posts of ch1 and ch2. use channel 1 input to drive the amplifier. dont gorget mx1500a is pin 3 positiveso speakers would be reverse polarity if you are using a diffrent amplifier to drive the other speakers.

You have a high power amplifier and the work you propose leaves no room for either error or compromise. If, as you suppose, the output is by complementary pair, the transistors must be matched pairs providing equal gain characteristics.
Unless you have seen inside a complete amplifier of the type you are only guessing at the output stage(s) that could be by module or a multiple transistor output. There also might be other driver stage(s) sharing the same heat sink.
The least you will need is a service manual and an internet search produced a number of results on the below link.
Generally an amp that IS bridgeable uses the positive speaker terminals and some switching method to tell the unit to run as bridged. This is NOT a recommendation to try it on the 5300.
Hi
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
I'm not sure if Lucent has a special bridging procedure, but on most if
not all other amps, when you bridge you DON'T connect two terminals
together. What you do is instead of using the plus and minus
terminals on one channel to one speaker and the other +/- terminals to
the other speaker, you will instead use the plus (+) terminal from one
channel and the minus (-) terminal from the other channel to drive one
speaker and the remaining + and - terminals remain unconnected. Be sure
you use the + and - terminals that are marked for bridging.
Please note, that when you bridge that your speaker load DOUBLES to
EACH channel. In other words, what your amp saw as a 4 ohm
speaker going to one channel alone, it now sees as a 2 ohm speaker on
each channel when bridged. Be sure you know what you are doing
before you bridge and fry your amp. In my experience, if after
bridging your amp works fine for about a month and then fries then you
bridged wrong and ended up with the wrong speaker load on each of the
bridged channels. Be careful. Amps cost a lot to
repair. Good luck.
im from Yamaha service before and i know this model can handle as low as 2ohms per channel. I have to check on my manuals though if bridged. i dont see any reason why it cant. and it has a bridge option input stage... let me get back to you again in the days to come.
