USING THE PRA-8
It is as simple as ABC to use and operate the PRA-8. Each of the eight pre-amplifier channels has its own INPUT (1) and OUTPUT (5)
and variable GAIN (2) control.
A. Connect a signal you wish to process to one of the XLR balanced INPUTS (1) on the front of the PRA-8.
B. Connect the corresponding channel OUTPUT (5) on the rear of the PRA-8 to your desired destination (mixer, recorder, etc).
C. Adjust the variable GAIN (2) control of that channel to the desired pre-amplified level. To ensure that you do not over pre-
amplify your signal, a PEAK (CLIP) LED INDICATOR (9) has been provided on the front panel of the PRA-8 for each channel.
When illuminated, this LED indicates that the pre-amplifier for that channel is overloaded and that distortion may result. Turn
down the variable GAIN (2) control for the selected channel until the PEAK (9) LED is no longer illuminated.
