This allows you to monitor the signal level sent post-tube to an external processor unit (switch out)

OUTPUT LEVEL switch
This configures the meter to show the output signal level. This works in conjunction with the output
level assignment switch on the back of the 576. When the rear switch is set to +4 dBu, a meter read-

of 0 VU corresponds to -10 dBV output.
