22:AC LINE IN: This heavy-duty, grounded, three-wire power cord is to be plugged into ONLY a safely-wired, grounded 120 volt, 60 cycle AC power outlet. DO NOT attempt to defeat the ground connection of this cable! If your GX-140C/CH was purchased outside of the United States, see the unit’s rear panel for its power rating and fol- low the above guidelines.

23,24: POWER AMP 1, 2 SPEAKERS: You may connect the outputs of the GX-140C/CH to your external speakers using these jacks. When connecting speakers use a matched pair; that is, two speakers with the same imped- ance to insure optimum performance from the amplifier. The amp 2 speaker jack (#24) carries the chorus signal (when the chorus is on) while the amp 1 jack (#23) is “dry” (without the chorus effect).

NOTE: The total impedance for each side should not be less than 4 ohms.

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

28:CHANNEL/GAIN SELECT FOOTSWITCH: Plug a dual footswitch (such as the Crate CFP-2 or the “stereo” plug of the Crate CFP-3) here to control Channel Selection and the Gain Select button. The footswitch overrides the front panel switches (#5 and 9) and is wired as follows: Ring = Gain Select, tip = Channels, sleeve = ground.

29:CHORUS/EXPANDER FOOTSWITCH: Plug a single footswitch (such as the Crate CFP-1 or the “mono” plug of the Crate CFP-3) here to control the Chorus/Expander. The footswitch overrides the front panel on/off switch (#17); selection between the Chorus and the Expander is still controlled by the front panel selector switch (#18).

Connecting to the Insert jack:

The Insert jack (#16) 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.

IMPORTANT NOTE ABOUT CERTAIN EXPORT UNITS: In some areas 1/4” speaker jacks are not acceptable for use on amplifiers capable of high output power levels. For this reason the 1/4” speaker jacks on your amplifier may be sealed – in this case, use the Speakon® jacks provided.

25:STEREO LINE IN: When using a stereo effects deivce, connect its output here. This stereo 1/4” phone jack is wired as follows: Ring = amp 1, tip = amp 2, sleeve = ground.

26:STEREO LINE OUT: When using a stereo effects deivce, connect this jack to its input. This stereo 1/4” phone jack is wired as follows: Ring = output 1, tip = out- put 2, sleeve = ground.

If your effects device has stereo input and output jacks, use a pair of three-conductor stereo patch cords to con- nect to 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 connections, as shown to the right.

The GX-140CH is designed with a dual-channel configuration, allowing players to easily switch between clean and distorted sounds. It features a unique Gain control, enabling musicians to dial in just the right amount of overdrive for their style. The footswitchable gain boost option adds an extra layer of flexibility, perfect for transitioning between different playing styles.

On the other hand, the GX-140C is a combo amplifier that also delivers 140 watts of power. This model is equipped with a 12-inch speaker, which produces a rich and full sound that is ideal for gigs of any size.

Additionally, the combo version comes with built-in effects such as reverb, providing an enriched audio experience without needing external pedals.

Both amplifiers incorporate Crate's unique technology, including a dynamic tube emulation circuit that mimics the warm tone associated with classic tube amplifiers. This technology enables guitarists to achieve rich harmonics and responsiveness across a range of frequencies. The tone controls are extensive, providing players with the ability to sculpt their sound precisely to their liking.

In terms of connectivity, both models come equipped with an effects loop, making it easy to integrate pedals into your rig. They also feature a headphone output for silent practice and an external speaker jack for those looking to expand their sound options further.
