18.FUSE: This protects the unit from dam- age due to overload conditions or power line surges. If the fuse blows, replace it only with the same size and type.

19.AC LINE CORD: Plug this cord into a properly wired, grounded, 120 volt, 60 cycle outlet. DO NOT attempt to defeat the ground connection of this power cord! If your amplifier was purchased outside of the United States, see the unit’s rear panel label- ing for its power rating, and follow the above guidelines.

20.BALANCED LINE OUT: This XLR-type connector supplies a balanced preamp output signal for connecting to a house mixing board, recording console or external amplifier with balanced inputs. The signal can be set to Pre or Post EQ by the Pre/Post switch (#21). The line out signal level can be controlled by the Balanced Line Out Level control (#22).

21.PRE/POST SWITCH: You can select either Pre or Post EQ for the signal at the Balanced Line Out jack (#20) with this switch. When the switch is depressed, the signal at the jack is pre-EQ—a direct output, not affect- ed by the gain, contour, or graphic EQ. When the switch is in the out position, the signal is

post-EQ—the output signal is affected by the gain, contour and graphic EQ controls.

22.BALANCED LINE OUT LEVEL: Use this control to adjust the output signal at the Balanced Line Out jack (#20). This control works independently from the the front panel Master Level control.

Connecting to the Insert jack:

The Insert jack (#13) lets you patch external effects into the amplifier just prior to its power amp stage. Use Crate’s STP201, STP202 or STP203 stereo-to-mono Y-cord or an adapter such as Crate’s YPP117 and 2 1/4” mono signal cables to connect to the effect as shown below.
