Do not use 2-conductor extension cords or anything other than 3polegrounded outlets for this appliance. Your life may depend on it! Please observe the following points when transporting your Einstein: Einstein is a tube-powered amplifier; therefore it is sensitive to shock especiallyafter playing the amplifier for a while. Please store and transport your amplifiergently and try to avoid extreme temperatures, which might produce condensation,resulting in moisture on internal components.
Chapter Two: Using Your Einstein 2.1 Mains Connections, Power and Standby 2.1.1 Mains/Connection to Power Outlet Please make sure that both switches (Power and Standby) are in the off positionbefore connecting to the mains circuit. Verify line voltage before connecting thepower cord. Never start Einstein without connecting speakers to the properterminals. (See 3.2.5) 2.1.2 Power up, Warm up, Standby off First, turn the Power switch to on (facing up). The indicator light will turn on.
2.1.5 Power Tube Life The power tubes of your amplifier are subjected to a certain aging process. Oncesigns of aging, such as unreliability or unusual noise, are detected, we suggest thatyou replace all power tubes at once. Matched tube sets age relatively evenly, soour experience suggests. This means that if one goes, the others are not far frommeeting the same fate.The aging process manifests itself by a depletion of a thin layer of wolfram on theanodes.
tell a component’s true advantages until it is used inthe right context.A guitar that has very piercing highs could theoretically be tamed down somewhatby using a long guitar cord that offers some high-end attenuation.The loops of your Einstein send signals at higher levels and impedances, whichmakes this section of wiring less sensitive. You should still use reliable and goodquality wiring for all loops. 3.2 Rear Panel Connections 3.2.1 Send/Return Loop The system consists of 2 separate Loops.
Volume control in the rear determines how much effect signal is beingadded to the original signal, which now still flows through the amplifier. There isalways an analog connection between the send and return jacks; a parallel loop!Important: You must set the mix control on the effects unit to 100% wet when using the parallel loop. Otherwise there will be nasty phasing problems resultingin unsatisfactory tone.
3.2.5 Speaker Connections Einstein has 5 speaker jacks. 1 for a 16Ohm load, 2 for 2 16Ohm loads or 1 8Ohm load, and 2 for 2 8 Ohm loads or 1 4 Ohm load. Confusing? Oh yes!Just do what it says on the jacks, and you’ll be fine Chapter Four: Two Pre-Amplifiers 4.1 Pre-Amplifiers and their Jobs The Diezel Einstein comes equipped with 2 different and totally independentpreamps. This allows the artist to play through nearly all musical-styles withouthaving to make major changes to his/her amplifier.
4.1.2 Channel Two (high gain) This channel is voiced for single notes, or for very heavy and massive rhythmguitar. Due to its slight midrange accent and very high gain, it possesses a goodpunch, will play with ease, and gain authority to rule any stage, or studio. The“less is often more” rule applies here also. 4.2 Pre-amplifier Tubes The pre-amps are equipped with 12AX7 tubes in all positions. The preamp tubesare not designed to produce high power output.
Chapter Five: Power Amplifier 5.1 Tone and Volume of the Power Amplifier 5.1.1 Master Volume As the name suggests, this controls the overall, volume of the amplifier. There is also a second, selectable master volume control, which allows volume adjustments via remote control device while playing. 5.1.2 Presence The presence knob controls frequencies over 3kHz.
brand and tube typewill change during production. You can fine-tune your Einstein by havingdifferent type and brands of tubes installed, however, it is imperative that the ampis biased properly. Einstein utilizes 4 power tubes, organized in 2 pairs with dualbias possibility. This allows use of 2 different pairs of power tubes, either thesame or the different types. Yes, this means that in a 4- tube Einstein, you can mix6550’s with EL34’s, or 6L6’s with KT88’s etc.
Chapter Six: Layout of Controls 6.1 Manual Channel Selection The 2 channels of the Einstein can be selected manually by activating the selectswitch for either channel. Alternatively, a foot switch can be connected toremotely control the channel selection. 6.2 Master 2 On/Off Master 2 can be used for all channels, and can also be remotely controlled via theincluded foot switch. This allows instant volume boost, or cut, without fiddlingwith the amp.
Chapter Seven: Maintenance and Cleaning 7.1 Cleaning Never use anything wet to clean the amplifier, any amplifier. Usually, it issufficient to wipe down the outside of the amp with a slightly moist cleaning rag. Do not use abrasive cleaning chemicals. Sometimes a vacuum cleaner can be usedto remove dust and dirt from nooks and crevices. Do not remove the chassis from the housing to clean the amp; the inside of your amp carries dangerous Voltages. 7.2 Care Be gentle with this Amplifier.
