FP33 adjust output

[Kerry Brown]

Go to Radio Shack puchace 2 1200 ohm 1/2 watt resistors, put them in parallel (=600 ohm) across the output of the FP33 pins 2&3 of the XLR. Buy a $5 volt meter at Radio Shack or Home Depot.
Set it to AC , lowest voltage scale and measure the voltage.

Thanks Kerry,

First answer, including emails back and forth to Shure, that is concrete enough given my level of electrical experience

“You understand that if you reset the meters, that will have ZERO effect on the actual LEVELS coming out of the mixer, right?”

No I did not understand this. Thanks. So other than pads there is no way of adjusting the actual levels? Will the sound devices 302 output at the right level (-10)?

PS: I’m sure some one could explain to me how to attach the resistors to the XLR pins. Or how to build the home made pads.

Not true, the first adjustment is for the output level and then you adjust the meters.

I also advise him to find a tech friend to help.

[Kerry Brown] “Not true, the first adjustment is for the output level and then you adjust the meters.”

All this procedure does is reduce the “volume” level (output signal level) using the controls and then adjusts the meter to compensate the reading to match the lower level.

Its no different than simply turning down the “volume” a bit (and just ignoring the meters.)

To reduce the actual output from the mixer, you need pads.

The difference would be very noticeable if, say, there was hum or hiss coming from the output section amp of the mixer.

Just turning down the input controls would reduce the signal level… but would not lessen the noise level.

But adding PADS would reduce the noise level as well as the signal level.

hi guys i need some help with my shure fp 33 when it is no and it is working i test it with camera but the peak/lim is not moving any help thanks ?
