User manual MARSHALL AMPLIFIER JCM800 KERRY KING SIGNATURE

[. . . ] Its always great to spend time with someone who is passionate about their music and tone, and of course, always great to know that it is a Marshall amplifier that feeds it. Dr Jim Marshall OBE and daughter Victoria (Managing Director) Kerry has already been using the 2203KK for some time now, ensuring it met his demands and using it every night as he travelled the world on his 2006 and 2007 tours. You can read his thoughts in this handbook; it makes me feel proud and is such a testament to hard work, that after 40 years, Marshall still provides such inspiration to a guitarist. This is our aim for every guitarist, to give you the amplifier with the tone, feeling and ease of use you want. I would like to wish you every success with your new amplifier and welcome you to the ever increasing Marshall family. Dr. [. . . ] Your Marshall dealer will be able to assist you in finding a Marshall authorised technician. 8. PRE AMP VOLUME Turning this control clockwise overdrives the pre-amp valves and creates a harmonically rich distortion 2. STANDBY SWITCH The Standby Switch is used in conjunction with the Power Switch (item 1) to `warm up' the amplifier before use and to prolong the life of the output valves. When powering up the amplifier always engage the Power Switch first, leaving the Standby switch on `Standby' for 2 minutes, allowing the valves to come up to their correct operating temperatures. Afterwards the Standby Switch can be engaged, enabling the HT without `shocking' cold valves. The Standby Switch should also be used to turn the amplifier `on' and `off' during breaks in a performance. Also, when switching off, always disengage the Standby Switch prior to the main Power Switch. 9. "THE BEAST" Switch and indicator LEDs This switch engages the Kerry King Signature tone. "THE BEAST" switch engages the ASSAULT and GATE circuits. Its LED will light in RED when the expander circuitry is in noise reduction mode (gate closed) and GREEN when the expander is open letting the signal pass without any attenuation. 7. MAINS FUSE The correct value of this MAINS fuse is specified on the rear panel of the amplifier. For safety reasons NEVER attempt to bypass the fuse or fit one of incorrect value. IMPORTANT NOTE: Always ensure that there is a load (speaker) attached before connecting the mains lead. ALWAYS ensure that the correct mains voltage applicable for the country where the 2203KK is being used matches the rating on the rear panel. IMPORTANT NOTE: Your 2203KK should always be completely powered down before the mains lead is removed. Technical Specification Power Output - 100W RMS Dimensions - 750mm x 310mm x 215mm Weight - 21. 5Kg 10. GATE, THRESHOLD The GATE control adjusts the 2203KK internal expander circuitry. This circuitry replaces Kerry's noise gate with an ultra fast studio quality noise reducer unit. Instead of abruptly cutting the sound once the threshold is reached like a noise gate, the expander progressively attenuates the signal following its dynamics. The THRESHOLD control has a program dependent decay ratio allowing very slow decay times for slowly moving guitar signals thus maintaining the natural sustain and very fast decays for staccato rhythms and short pauses. [. . . ] Turning it clockwise increases the mids and fattens your sound, giving it more punch. Turning it anticlockwise reduces the mids, producing a more 'scooped' tone. 6. TREBLE CONTROL This adjusts the top-end. Turning it clockwise increases the amount of high frequencies present in the sound, giving your guitar tone a brighter edge. [. . . ]
