Hello all!
First Let me say that I have very little experience in electronic circuit deign. My education did not include IC studies (unfortunately).
The problem:
I have a console with outputs of 150 ohms, they are intended to drive a 600 ohm load.
These outputs I would like to use as the monitor path going into a passive controller (attenuator and a/b/c switch, mute/mono) selecting between multiple monitors.
The controllers inputs are 10k ohm.
In order to use this passive device, I need to construct a device that raises the consoles output impedance into an acceptable range for the controller. I have been told this circuit is a unity-gain opamp current buffer. Correct me on the name, as that may help my research!
Can anyone point me to a circuit diagram or reference material for this type of device?
Thank you
