G40CXL STEREO
CHORUS AMPLIFIER
We would like to take this opportunity to thank you for selecting a Crate product, and to tell you of our commitment to the design and manufacture of only the finest musical instrument amplifi­cation equipment; built for you, the musician.
You have purchased one of the most innovative sound amplification devices available today. Your Crate amplifier gives you more performance features than ever before; features that you, the musician, have asked for.
All Crate amplifiers are subject to seven or more inspection and testing steps to assure you of a high quality product. The final test for each amp is conducted by a trained musician with the instrument the amp was designed for. Any unit that does not meet the standards of his discrim­inating ear will not be passed.
Since all Crate products are designed, developed and manufactured through the cooperative efforts of engineers and professional musicians, the end result is a product that responds to the musician’s audio requirements, and a product that will serve your needs for years to come.

FRONT PANEL – INPUT SECTION
1. 0dB INPUT JACK: This input accepts a
standard 1/4” phone plug and is suitable for any low to line level signal source such as an electric guitar.
2. -6dB INPUT JACK: This input jack also accepts a standard 1/4” jack but is padded 6 dB for hotter inputs such as tape decks or guitars with hot pickups. If both jacks are used, this input is not padded and will be equal to the 0 dB input jack.
CHANNEL A CONTROLS:
3. GAIN CONTROL: This control sets the
amount of gain for Channel A and is used to vary the amount of distortion. Minimal distortion is achieved with this control rotated counter-clockwise. A fully clockwise setting creates maximum distortion.
4. LEVEL CONTROL: The overall volume of Channel Ais controlled with this knob and should be used in conjunction with the Gain Control (3).
5. SHAPE CONTROL: This is the overall tone control for Channel A. When turned to the left, a setting with heavy emphasis on mid range is achieved. When rotated to the right, the amp cre­ates a “fat” sound with extra boost on lows and highs.
6. CHANNEL SELECT SWITCH: This switch is used to select between Channel Aand Channel B. When using the optional footswitch (23), this switch is inoperative.
CHANNEL A CONTROLS:
7. VOLUME CONTROL: This control sets
the overall listening level of Channel B. This control is independent of any set­ting made in Channel A.
8. LOW CONTROL (Bass): The desired amount of “Bottom” or “Warmth” may be increased or decreased with this knob.
9. MID CONTROL (Mid): The tonal quali­ties of the midrange are very important to a good guitar sound. This knob can “thin-out” the sound when turned down, or “fatten-up the sound when larger amounts are used.
10. HIGH CONTROL (Treble): This knob will affect the upper harmonic range of the guitar. Boosting it sharpens or adds crispness to the sound. For additional effect, use this control in conjunction with the Bright Switch (11).
11. BRIGHT SWITCH: This switch affects the brilliance of the guitar’s sound by adding additional “bite” or sharpness. This switch affects both Channel A and B.
12. DEPTH CONTROL (REVERB): This control allows the player to alter the apparent acoustical qualities of a room. The sound can be altered from very “Flat” or “Dry” when the control is turned off, to that of a concert hall when used in larger amounts.
CHORUS SECTION
13. CHORUS SWITCH: This switch turns
on the stereo chorus when depressed. It must be in this position to enable the chorus footswitch (24).
G40CXL Amplifier
14. DEPTH: This control sets the amount or
depth of the chorus effect.
15. RATE: This control sets the sweep speed of the chorus effect. Together, these two chorus controls determine the overall chorus effect from a slow , “phas­ing” sound to a lively, shimmering effect and beyond. The stereo nature of the G40CXL gives a “three-dimensional” quality to the unit making it sound full and “alive.”
16. INSERT JACK: This stereo 1/4” jack is a line out (tip)/line in (ring) jack.
17. HEADPHONES JACK: Standard stereo headphones may be plugged into this jack. This disconnects all speakers from the unit. allowing private listening.
18. ON/OFF LED INDICA TOR: The amplifi­er is on when this LED is lit.
19. ON/OFF SWITCH: This is a two-posi­tion switch; the down position will turn the unit on, while the up position will turn the unit off.
