Resumen del manual
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 22dB at 80Hz. 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 600Hz. 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 28dB at 10kHz. 14: DSP LEVEL: Adjust the amount of digital signal processing with this control: in the full-left position the output signal is “dry” (no effect); rotating the control to the right increases the amount of effect. The DSP can be turned on and off with a footswitch (#23). 15: DSP MODE: Select the type of digital effect(s) desired with this control. Each category and its central location is called out (delay, flange, etc.) by the markings around the control; there are two variations per effect, as follows: • Slapback delay • Long delay w/regeneration • Light Flange • Heavy Flange • Slow Chorus • Fast Chorus • Chorus w/small room reverb • Chorus w/large room reverb • Small room reverb • Large room reverb 16: INSERT: 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. 17: EXT. SPEAKER: Connect to an extension speaker cabinet with this jack. The jack is wired in series with the internal speaker(s). 18: POWER ON LED: Lights when the amplifier is turned on. 19: POWER SWITCH: Turns the amplifier ON in the up position, off in the down position. 20. POWER CORD (rear panel, not shown): Your GFX-120/212 is equipped with a heavy-duty grounded three-wire power cord. Be sure this cord is properly plugged into a safely wired grounded 120 volt, 60Hz AC power outlet before use. (If your GFX-120/212 was purchased outside the United States, refer to the rear panel for power ratings.) For your safety, never attempt to defeat the ground connection on this cord. 21: FUSE (rear panel, not shown): Protects the amplifier against damages caused from a faulty AC power source or other problems. 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, contact your Crate dealer for service information. 22: CHANNEL SELECT / GAIN FOOTSWITCH JACK (rear panel, not shown): Connect the stereo 1/4” plug of the supplied three-button footswitch here for remote control of the Channel Select and Gain Select settings. 23: DSP FOOTSWITCH JACK (rear panel, not shown): Connect the mono 1/4” plug of the supplied three-button footswitch here for remote control of the DSP on and off. 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 stereoto- 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.
