=== Preamps ===

Q: Do I get the benefits of the Preamps if I use the ¼ inch inputs on the {{PS1}} Channel 1 or 2

A: Yes. Whether or you use the Input Line (¼ inch) or XLR input the signal flows through the Preamp.

Both XLR and ¼ inch input go through the same preamp but they see a little different conditioning before they get there. The XLR connects to a is balanced low impedance input stage with a lot of gain. The ¼ inch input is unbalanced, has about 20 dB less overall gain but a very high input impedance.

Both XLR and ¼ inch input go through the same preamp but they see a little different conditioning before they get there.

* The XLR connects to a is balanced low impedance input stage with a lot of gain.

* The ¼ inch input is unbalanced, has about 20 dB less overall gain but a very high input impedance.

Q: What is the input impedance of the ¼ inch Channel 1 or Channel 2 Inputs

A: Approximately 1 megOhm.

Here is an illustration that may help.
