YAMAHA PM1000 EQ QUESTION

[bluesman714]

I am racking up some PM1000 channel strips. I have been reading this forum for a couple of years & have read in several postings that the EQ switches (EQ & High Pass) are pretty useless (in the opinion of the poster). Is this something I need to make available on the face of the racked unit, or is it something that is a set it & forget it item that could be tucked away inside the box?
Mounting the original switches on my recycled faceplate is possible, although a PITA, the orginals are mounted on a small circuit board....two switches mounted on the same circuit board...so I have to use the original spacing. I know lots of people have been racking up these units & really like the sound.....so tell me......Do You Ever Use these Switches, or did you just mount them because they were there?

No, the eq is totally usable, it's just that the frequencies that were chosen for the midrange aren't that usable. It's really easy to change them.

I tried a few different film caps in the eq section (including some el cheapos) and ending up settling on some of the brown Panasonic films. I can't remember what exactly the model number is , but they're in digikey, and if you take down the uF ratings that tubejay ends up using in that post, the Panasonics I'm talking about are one of the few caps in digikey that have all those uF values. They sound cool too. Much more beefy than the cheaper AVX brand.

Jonk, thanks for your response. I have found a way to use the original chassis as a mounting switchplate......problem solved & the switches will be included on the new faceplate.

I would say don't use the original faceplate, not because there's anything wrong with it but because it forces you to use those switches. The mid frequency and hi-pass switches are things you need on the faceplate, but aside from choosing dumb frequencies for the mid EQ, Yamaha also used switches that are, to use an industry technical term, "jiveass bullshit." They are lousy switches that are difficult to operate, always dirty and noisy, and just a pain all the way around. You are very fortunate that they are mounted together on a separate circuitboard because that allows you to ditch that litte circuitboard and use new switches of your own choosing. They can be a different type of switch if you like, perhaps a rotary. You don't need a circuitboard for the switches, you can just hardwire them and mount them on your faceplate. Since none of the controls are attached to the main circuitboard, you can (if you wish) replace all of them, eliminate some of them, or whatever you want to do.
But if you keep the faceplate, then you're kind of stuck using the controls that fit on the faceplate.
