As you can see, there are 8 screws holding the woofer in. Remove them, lift the speaker up, but before you disconnect it....Mark + and - onto the wires...red + and black -. .http://i46.tinypic.com/14l3j0z.jpg
Remove the backplate and the wires are often hold togeter with a tiedrap, so you need a long , how do you call it in english:) , sciccoskind tool or you can try to unplug, the plugs between the powerunit/ amplifier and you speakers . I'm busy rebuildimg m3-8 from m-audio, cause of some where cheap amp/powerunit and did it by hand and i have large hand, but put some tape around the backplatesurrounding for scratches.
And if you have them loose you can remove them.... but why?
Do you think you just can replace them for other once, think again
Make the sure the cables are connected properly to the monitors, as in Left Positive to Left Positive, Left Negative to Left Negative on both ends of the cable. Having one polarity switched can burn out your speaker and internal electronics.... I'm speaking from experience. When you burn up a $400 speaker by incorrectly connecting them... it's a big OOPS that makes you feel pretty dumb. Even as a professional A/V guy, it happens.... and sucks. If this doesn't fix the problem, contact Yamaha or an authorized dealer about it. Could be bad electronics internally, but my guess is it's the cables being improperly connected.
Qualifier: I have 901's in a 7.1 setup and have written many posts on Fixya regarding how to do it right.
NEVER USE MAXIMUM VOLUME FOR ANY PURPOSE UNLESS THE RISK OF ACCIDENTAL SPEAKER DESTRUCTION IS A ACCEPTABLE.
ONLY now it does that? "VERY WEAK" as in attentuated somewhat or is it signal leakage, effectively silence? How is the EQ wired in? Check its own Tape Monitor button.
If you DO NOT have a separate amplifier for the 901's the EQ will affect EVERY speaker and we know that is NOT desired.
If the EQ is in a Tape Loop of a modern AVR and you activate the loop two things will happen: 1) the 901's will sound better and the rest of the speakers will be at risk from excessive amplitude at the extremes; 2) any digital source will be disabled.
Hi, Check too see that somehow a " TAPE MON." button did not get pressed. having the tape monitor engaged will null anything but a tape fronm being played. or it even could be calle vcr mon. but either way peculiar problem. I hope this helps, let us know if it did,write back too if not. Good luck, Prodzilla
Hiya, i assume for now that you mean the 16dip switch. If i remember correctly it is solder directly to board (could be wrong). If you are comfortable with doing this, it will need to be opened and resoldered probably for dry joints. If not then suggest hunting out a friend with some solder experience. A word of caution though, shorting out solder tracks etc could result in damage so only do it if you are comfortable. If the dry joints are really bad (sound like they are) you should be able to see them clearly and resolder (look for not so bright and shiny solder that looks cracked. Magnifier helps)
I have a pair of BX5a monitors hooked up to a video editing suite. One
of the monitors is off. They are powered to a working electrical
supply. They are driven off a Mackie DFX-6 with a 1/4" unbalanced
connection. No blue light on the monitor, no sound or hissing on
If your monitor is crackling and fizzing, that is not a fuse issue, unless the fuse you have installed is underrated. It sounds like you have a bad driver/woofer, and need to get it replaced. CLICK HERE FOR THE REPLACEMENT DRIVER for this model.
