15:INSERT: Connect an external effects device via this jack. Use a stereo 1/4” male Y-cord: ring = send, tip = return, sleeve = ground. See the illustration on the panel to the right for more information

16:POWER ON LED: Lights when the amplifier is turned on.

17:POWER SWITCH: Turns the amplifier ON in the up position, off in the down position.

18.POWER CORD (rear panel, not shown): Your GX-1200H is equipped with a heavy-duty grounded three-wire power cord. Be sure this cord is properly plugged into a safely wired grounded 120 volt, 60Hz AC power outlet before use. (If your GX-1200H was purchased outside the United States, refer to the rear panel for power ratings.) For your safety, never attempt to defeat the ground connection on this cord.

19:SPEAKER JACKS (rear panel, not shown): Use these 1/4” output jacks to connect the amplifier to your speaker cabinet(s). Use heavy gauge speaker cables. The GX-1200H can operate into speaker loads as low as 4 ohms.

20:FUSE (rear panel, not shown): Protects the amplifier against damages caused from a faulty AC power source or other problems. If the fuse blows, replace it ONLY with the same size and type fuse. If the fuse blows repeatedly check the AC source; if it’s okay, contact your Crate dealer for service information.

21:CHANNEL SELECT / GAIN FOOTSWITCH JACK (rear panel, not shown): Connect the stereo 1/4” plug of the supplied three-button footswitch here for remote control of the Channel Select and Gain Select settings.

22:REVERB FOOTSWITCH JACK (rear panel, not shown): Connect the mono 1/4” plug of the sup- plied three-button footswitch here for remote control of the reverb on and off.

Connecting to the Insert jack:

The Insert jack (#15) 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.
