Pez, could you explain what the buffer circuit actually does? I've always equated buffering to allowing a better impedance match between output and input, and have thought of it as passive. Is that right? If it is passive how can the iTube 2 offer 9 dB of gain?
According to the user's manual the input impedance is 1,000,000 ohms for the buffer and 100,000 ohms for the preamp. What is the recommended ratio of output to input impedance?
Output stage impedance is stated as < 1 ohm and corrected output impedance as <150 ohms. What is a "corrected" impedance?
Thanks In Advance
