Re: VU BUFFER & PEAK LED KIT BUILD THREAD

A few really dumb questions: To Setup VU Buffer and Peak LED pcb. 1. Connect dc power you are using. VU buffer and peak led can run on +12 to +36vdc @ 30mA so main current draw will usually be the VU meter light. I am using 12 volts-seems to work fine. 2. Send 1kHz tone in at the reference level you...

Re: VU2 stereo VU buffer kit Build thread

Thanks for your quick reply. Another question: What voltage does the yellow LED in the meter use. Is there a place on the PCB board to wire to the meter LED?
Sorry for the dumb questions.

Re: VU2 stereo VU buffer kit Build thread

My kits have arrived. The meters (SEW ST-315) come with no mounting or hook-up instructions. There are 4 solder lugs on the back. I assume 2 are meter inputs and 2 are for the led. Which is which? Which is + and which is -?

Re: VU2 stereo VU buffer kit Build thread

I just purchased the SEW 315 VU meters to go along with the VU2 buffer kits. Do these meters have internal rectifiers?
