GX-212 Amplifier

16:EXT. SPEAKER: Use this jack to connect an extension speaker cabinet to the amplifier. This jack is wired in series with the internal speaker(s).

WARNING: Do not attempt to use head- phones in the Speaker jack! Permanent hearing damage could result!

17:POWER ON LED: This LED illuminates when the amplifier is turned on.

18:POWER SWITCH: Use this switch to turn the amplifier on (top of the switch depressed) and off (bottom of the switch depressed).

19.POWER CORD (rear panel, not shown): The grounded power cord should only be plugged into a grounded power outlet that meets all applicable electrical codes and is compatible with the voltage, power, and frequency require- ments stated on the rear panel. Do not attempt to defeat the safety ground connection.

20:FUSE (rear panel, not shown): This pro- tects the amplifier against damages caused from a faulty AC power source or other prob- lems. 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, con- tact your Crate dealer for service information.

21:CHANNEL SELECT / GAIN FOOTSWITCH JACK (rear panel, not shown): Use this jack to connect the 1/4” stereo plug on the footswitch cable to the three-button footswitch (supplied). This allows you to remotely switch between the Clean and Overdrive channels and between Gain 1 and 2 of the Overdrive channel.

22:REVERB FOOTSWITCH JACK (rear panel, not shown): Use this jack to connect the 1/4” mono plug on the footswitch cable to the three- button footswitch (supplied). This allows you to remotely turn 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 in the illustration below.
