Owner's Guide for the CRATE Guitar Amplifier
Guitar Amplifier Congratulations! You are now the proud owner of the Crate MFX1200H Guitar Amplifier. This rugged amp head combines outstanding features with serious clean and distorted sounds. An easy to operate DSP section lets you dial in a variety of digital effects such as delay, flange, chorus and reverb – with its own level control. Channel selection, Crate’s exclusive Shape circuit, and DSP on/off are controllable by the supplied three-button footswitch.
Guitar Amplifier 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.
Guitar Amplifier The Front Panel: 1: INPUT: Use this 1/4” jack to connect your instrument 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 1: Use this control to adjust the input gain for the Overdrive channel. Gain 1 produces less distortion than Gain 2 (#3) and is active when the Gain switch (#5) is in the out position.
Guitar Amplifier the high frequency output. Rotating the control clockwise increases the high frequency output. The High control provides a range of 28dB of boost or cut at 10kHz. 14: DSP LEVEL: Use this control to adjust the amount of digital signal processing to be applied to the signal. In the fully counterclockwise position the output signal is “dry” (no effect applied). As you rotate the control clockwise the amount of effect increases. The DSP may be turned on and off with a footswitch (#17).
