One of the circuits here has level controls. More importantly, there is very good explanation of the circuits:

I have used the information here to successfully design and build my own circuits.

Thanks. I should be able to use lower value resistors (need to double check the power draw).
You used the formula for parellel resistors. However, a voltage divider looks like resistors in series to me. I will look into this more.

Thanks for the response...
Here is the portion where the control signal (5v DC) enters the circuit (pin 6 of the DIN), passes through the voltage divider and connects to the control pin (3).
It may be hard to read, but the voltage divider is comprised of a 6.8K and a 1K resistor. This...
Hello,
I have what is a really basic question.
I am working with an Voltage Controlled Amplifier which states the following about its control ports (ports 2 and 3):
The 2180 Series VCAs are designed to be
operated with zero source impedance at pins 2 and
3, and an infinite source impedance at...
