Hey guys;

I've built a 5 band version of RGs parametric EQ


I have a prebuilt dual +/-15v supply in a case that I'd like to mount it in. To adapt this circuit for dual supply, is it just a matter of connecting all the grounds to -15v and all the Vb+ to ground?

Thanks

PRR

No.

Chip pins 4 go to V-. All other grounds go to zero V.

Thanks for your reply PRR. There are also connections to Vb+ (i.e., V+/2). Do they also go to 0V?

Thanks again

PRR is correct. All pin 4s on the 5532s go to -15V. Vb (I'm assuming is the reference voltage) goes to 0V.

tempus

Yes, Vb is the reference voltage.

OK I'll give it a try. Thanks for the replies guys
