- like the Rocktron Velocity 100 and from the power amp into two 4x12s, a stereo 4x12 or a stereo 2x12
cabinet. The preamp output is controlled by the master volume control.
LINE OUT - TO RECORDING DEVICE
This 1/4” jack allows you to connect to a PA system or recording device. The Speaker Simulator should be
engaged for the best sound. You may also run the signal out to a power amp with volume controls and
from there into a speaker cabinet. This output is ideal for direct connection to a PA system for live
performances....it eliminates the need to use a microphone with the PA. The line output is not controlled by
the master volume control.

outlet may not be properly grounded. Set the switch to the postion that provides the least amount of “hum”.
