Chapter One: Safety and Warranty 1.1 Safety warnings We would like to stress the importance of the following points, for reasons ofyour personal safety, product longevity and product liability. Do not use the Amplifier in or near wet locations Do not store the Amplifier in damp or wet locations Do not operate the Amplifier on voltages other than those designated on the rear panel of the amplifier. Do not open the panels of the amplifier. No user serviceable parts inside.
Chapter Two: Using Your Schmidt 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 position before connecting to the mains circuit. Verify line voltage before connecting the power cord. Never start Schmidt without connecting speakers to the proper terminals. (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.
2.1.4 Operating Temperature It will take a little more time after warm-up until everything inside the amp is working in sync and to its fullest potential. A trained ear will notice a slightly warmer tone and better complexity in tone after playing the amp for a short while. It’s like stretching before exercising. 2.1.5 Power Tube Life The power tubes of your amplifier are subjected to a certain aging process.
3.1.3 Cable Selection In certain circumstances, it is desirable to match a guitar cord to a specific instrument. One may use the otherwise undesirable qualities of a cord to one’s advantage, if one has the time and patience to experiment with different cords and guitars. This should be done while playing with your band, or while recording. Sometimes it is difficult to tell a component’s true advantages until it is used in the right context.
3.2.2 Parallel or Serial Which is better for you? Read on.There are 2 ways to handle effects signals. The serial loop interrupts the signal path of the Schmidt and the signal is sent to the processor, becomes processed, then sent back to the serial return into the power amp. Digital effects units often digitize this signal once received, then process the signal, convert it back toanalog, then send it to the amp. This is called ADA (analog digital analog) conversion.
3.2.4 Compensated Out A frequency corrected signal will leave this jack if you connect it to a mixer or recording device. Use it to quietly compose or send an auxiliary signal to a console etc. The comp out is located after the pre- and power amp, so it is a must that the amplifier is running either with a speaker or a loadbox (THD HotPlate or similar). 3.2.5 Speaker Connections There are 5 speaker outputs available on the rear panel.
3.2.6 Switching Included with your carton a proprietary footswitch shipped with your amp. Hook a standard mono guitar cable (instrument or speaker, included) between the footswitch and the FS5S-jack on the back of your amp. The footswitch controls all channels, the loop and the reverb.
Chapter Four: Two (and a half) Pre-Amplifiers 4.1 Pre-Amplifiers and their Jobs The Diezel Schmidt comes equipped with 2 different and totally independent preamps each with its own Reverb pot. This allows the artist to play through nearly all musical-styles without having to make major changes to his/her amplifier. The preamps are voiced to deliver the most wanted guitar tone flavors: Clean, Crunch, Heavy, Lead.
4.2 Pre-amplifier Tubes The pre-amps are equipped with 12AX7 tubes in all positions. The pre-amp tubes are not designed to produce high power output. Therefore, their life expectancy is much higher than that of the power amplifier tubes.This is not to undermine their utter importance in overall sound and response ofthe amplifier. Also, annoying defects like crackling noises and low dynamics are directly related to defective preamp tubes.
Chapter Five: Power Amplifier 5.1 Tone and Volume of the Power Amplifier 5.1.1 Channel Volume As the name suggests, this controls the overall, volume of the amplifier’s channel. The more the channel volume is increased, the higher the rate of power amp warmth (until power amp distortion is achieved) will be. 5.2 Power Amplifier Tubes 5.2.1 Function As the name suggests, the power amp section is the part of the amplifier that produces output power, measured in watts.
Chapter Six: Layout of Controls 6.1 Manual Channel Selection On the left of the pots are the switches for the channels and the loop on/off switch. Each switch also has an LED indicator, the loop LED on the left of the switch, the channel’s LED are located between the pots of each channel. . 6.2 Switching If you should prefer to use Schmidt inside a more complex rig, then Diezel provides three switching jacks on the back of the amp (labelled “reverb”, “channel 3/loop”, “channel 1/2”).
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.
If the amp will not switch on, please check this fuse first and in case that the inner fuse of the drawer will need replacement, please only use those values which are labelled underneath the mains jack. The dimension of the fuse is 5x20mm. Also the power tubes have their own fuse and an indicator on the back. In case that the power tubes are faulty the amplifier will stop to operate and you will need a replacement of the power tubes and this fuse. The value of the fuse is labelled to the backpanel (0.
