OWNER’S MANUAL

Congratulations!

You are now the proud owner of the versatile and powerful Crate GX-140C Combo Amplifier / GX-140CH Amp Head with Stereo Chorus. With two flexible channels, Crate’s patented “Flex Wave” distortion circuitry, a Stereo Effects Loop and three footswitchable functions, the GX-140C/CH offers you more flexibility and performance than any amplifier in its class.

Like all Crate products, your GX-140C/CH is Musician Made in the U.S.A., using only the best components. Extensive testing at the hands (and ears) of skilled technicians and musicians insures you that this amplifier is the absolute best it can be.

In order to get the most out of your new amplifier, we strongly urge you to go over the information contained in this manual before you begin playing.

And thank you for choosing

GX-140C/CH Amplifier

FRONT PANEL:

1: INPUT: Connect your guitar here using a shielded instrument cable.

OVERDRIVE CHANNEL: A high gain channel giving you sounds from a slight edge to serious overdrive.

2:GAIN 1: When active, sets the amount of compression and distortion from the amplifier. At far left, the sound will have a thick compressed quality. As you turn the control to the right the amount of distortion increases. Gain 1 produces less intense distortion than Gain 2 and is active only when the Gain Select switch (#5) is out.

3:GAIN 2: When active, sets the amount of compression and distortion from the amplifier. At far left, the sound will have a thick compressed quality. As you turn the control to the right the amount of distortion increases. Gain 2 is produces more intense distortion than Gain 1 and is active only when the Gain Select switch (#5) is in.

4:SHAPE: Working in conjunction with the Gain 2 control, rotate the Shape control until you find the sound you’re looking for. Turning the control towards the left enhances the mid frequencies; turning it to the right enhances the low and high frequencies. (Only affects Gain 2 when active.)

5:GAIN SELECT: Switches between Gain 1 (out) and Gain 2 (in). A footswitch (see #28, rear panel) overrides this switch.

6:LOW: Adjusts the low frequency output level: to the left reduces the low frequency output; to the right increases it. This control allows a range of 10dB at 80Hz.

7:HIGH: Adjusts the high frequency output level: to the left reduces the high frequency output, to the right increases it. This control allows a range of 10dB at 7kHz.

8:LEVEL: Sets the output volume level from Channel A: in the far-left position there is no output; turning the control to the right increases the output. Use this control along with the Gain and Shape controls (#2, 3 & 4) to create a wide variety of sounds.

9:CHANNEL SELECT: When this switch is pressed in the Overdrive Channel is engaged. The Clean Channel is selected when this switch is out.Afootswitch (see #28, rear panel) overrides this switch. The adjacent LEDs indicate which channel is selected.

CLEAN CHANNEL: A normal gain channel designed to give you crystal clear sounds.

10: LEVEL: Sets the output volume level from the Clean Channel: in the far-left position there is no output; turning the control to the right increases the output level.

11:LOW: Adjusts the low frequency output level: to the left reduces the low frequency output; to the right increases it. This control allows a range of 20dB at 100Hz.

12:MID: Adjusts the mid frequency output level: to the left reduces the midrange output; turning it to the right increases it. This control allows a range of 14dB at 700Hz.

13:HIGH: Adjusts the high frequency output level: to the left reduces the high frequency output; to the right increases it. This control allows a range of 27dB at 10kHz.

14:REVERB, OVERDRIVE: Adjust the amount of reverb for the Overdrive Channel with this control: in the full-left position the output signal is “dry” (no reverb); rotating the control to the right increases the amount of effect.

15:REVERB, CLEAN: Adjust the amount of reverb for the Clean Channel with this control: in the full-left position the output signal is “dry” (no reverb); rotating the control to the right increases the amount of effect.

16:INSERT LOOP: 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. This is a mono pre-chorus effects loop.

17:CHORUS ON/OFF: Turn the Chorus/Expander on and off with this switch. When the switch is pressed in, the Chorus/Expander is active. A footswitch (see #29, rear panel) overrides this switch.

18:CHORUS/EXPANDER: Select between the built-in stereo chorus or the “expander” circuit with this switch. When the switch is pressed in, the chorus section is selected. When the switch is out, the amplifier’s expander circuit is activated, giving the sound a wide-open, “spatial” effect. In order for either effect to be active, the Chorus On/Off switch (#17) must be pressed in.

19:DEPTH: Set the intensity of the chorus effect with this control: in the far left position there will be almost no chorus; as you rotate the control to the right the amount of effect increases.

20:RATE: Set the speed of the chorus effect with this control: to the left for slow, smooth “phasing” sounds, to the right for faster “vibrato” sounds.

21:POWER SWITCH: Turns the amplifier ON in the up position, off in the down position. The Channel LED for the selected channel will light when the amp is switched on.
