Congratulations! You are now the proud owner of the compact but powerful Crate MX20RC amplifier. Two versatile channels – one crystal clear and the other with our patented “Flex-Wave” distortion – combined with reverb and a three-band EQ and a switchable Chorus offer you more flexibility and performance than any amp in its class. Our “Flex Wave” circuitry uses sequential cascading gains to deliver distortion which is rich in harmonics and is touch sensitive.
Important Safeguards and Precautions: All Crate products are designed for continuous safe operation. Abiding by the following rules can help prevent damage to your amplifier, yourself and others. • The amplifier is equipped with a three-pronged AC power cord. To reduce the risk of electrical shock, NEVER remove or otherwise attempt to defeat the ground pin of the power cord. • Connect the amplifier ONLY to a properly grounded AC outlet of the proper voltage for your amp.
The Front Panel: 1: INPUT: Use this 1/4” jack to connect your guitar to the amplifier by means of a shielded instrument cable. OVERDRIVE CHANNEL: A high gain channel giving you sounds from a slight edge to serious overdrive. 2: GAIN: Use this control to adjust the amount of distortion for the Overdrive channel. With the control counter clockwise, the sound will have a thick compressed quality. As you rotate the control clockwise the amount of distortion increases.
9: REVERB LEVEL: Use this control to adjust the amount of reverberation: in its full counter clockwise position the signal will be “dry” (without any reverb). As you rotate the control clockwise the amount of reverberation increases. 10: CHORUS: This switch, when depressed, activates the built-in, preset chorus effect to enhance the sound of either channel. 11: HEADPHONES: Use this jack to listen to the amplifier through a pair of stereo headphones.
