22:POWER CORD: This heavy-duty, grounded, three wire power cord is to be plugged into ONLY a safely-wired, ground- ed 120 volt 60 cycle AC power outlet. DO NOT attempt to defeat the ground connection of this cable! If your amplifier was purchased outside of the United States, see its rear panel for the proper power rating.

23:EXTERNAL SPEAKERS: You may connect the outputs of the GX-40C+/D to your external speakers having a rated impedance of at least 2 ohms each, using these jacks. When connecting speakers, use a matched pair: two with the same impedances, to insure optimum performance from the amplifier. Since these are series conenctions, there is no chance of dam- aging the amplifier with too small of an inpedacne load.

24:STEREO HEADPHONE / LINE OUT JACK: This dual- function stereo jack provides you with a means to connect a pair of stereo headphones for private practice sessions, or to obtain a stereo line-level output signal to send to a recording console, mixing board or to another pair of power amplifiers. The internal speakers are muted whenever a plug is inserted into this jack. The wiring for the jack is as follows:

Tip: Right channel

If your effects device has stereo input and output jacks, use a pair of three-conductor stereo patch cords to connect it. If the device has separate left and right jacks, use a pair of one- stereo-male to two-mono-female Y-adapters to make the con- nections.

26:FOOTSWITCH: Plug a dual footswitch (such as the Crate model FS-60) here to control channel selection and chorus on/off. This stereo 1/4” phone jack is wired as follows:

Tip: Channel select

Ring: Chorus on/off

Sleeve: Common ground

Connecting to the Insert jack:

The Insert jack (#16) lets you patch external effects into the ampli- fier just prior to its power amp stage. Use Crate’s CYC6MS stereo-to-mono Y-cord or an adapter such as Crate’s CA11Y and 2 1/4” mono signal cables to connect to the effect as shown below.

Stereo-to-mono Y-cord: Y-adapter and 2 cables:

Ring: Left channel

Sleeve: Common ground

WARNING: DO NOT attempt to use headphones in the Speaker jacks! Permanent hearing damage could result!

25:STEREO EFFECTS LOOP: Connect the SEND jack to the inputs of your stereo effects device to send a post-EQ, post- chorus, pre-amplified signal for processing. Connect the out- puts of the effects device to the RETURN jack to return the processed signal to the amplifier. The jacks are stereo 1/4” phone jacks, wired as follows:

Tip: Right channel

Ring: Left channel
