A full complement of Equalization controls is featured and includes low, middle and high frequency controls for total tonal balance between these frequency bands. We have built into this series a new type of reverberation circuit that delivers over 14 volts RMS to the built in reverberation unit. The preamplifiers, equalization, and reverb circuitry is complemented by a MASTER VOLUME CONTROL for even greater control of sustain, dynamics and sensitivity for recording studio applications. Our exclusive '‘AUTOMIX’’ ciruitry is built into this series for even greater flexibilty and “on stage” versatility. Your new Artist features two channels, “Bright” and “Normal” with four inputs that function along with the Automix footswitch to allow you to play through either channel, both channels in parallel, or both channels in series. Please read the explanation of each input and become familiar with the effects possible with the Automix footswitch. 1 The Bright input places the signal from your instrument into the bright channel only. This channel provides treble boost for a “brighter" sound from your guitar. 2 The Normal input places the signal from your instrument into the normal channel only. 3 The Parallel input places the signal from your instrument into both channels. Plugging into this parallel jack is the same as using a patch cord to bridge into the normal and bright channels, except that the internal circuitry automatically performs the patching function. When plugged-into this jack, both normal and bright channel volume controls are active and the desired blend of each can be found by varying the level of each, relative to the other. 4 The Series input places the signal from your instrument into both channels in series. By placing the channels in series incredible sustain and overload harmonics can be generated. Experimentation with various combinations of volume control settings will yield an infinite variety of harmonic characteristics and sustain durations. These functions can be used in conjunction with the master volume control to avoid driving the power amplifier to full output while seeking the desired effects enabling the operator to obtain sustain and overload effects at very low volume levels, such as those required in some recording studio applications. 5,6 Both the bright and normal channels have separate volume controls. These volume controls set the gain of the input preamp, thereby controlling the sensitivity of the preamp, not the power of the amp. It is entirely possible for the amp to be driven to full power output on very low volume settings if the signal from your instrument is extremely high. Please remember that the volume control does not indicate power output, but the gain of the preamp. 7 The bass control varies the amount of bass response in the system and is very effective in achieving a balanced tonal blend. 8 The middle control enables the musician to tailor the vital mid-range response. Experimentation with the unique middle circuit will show that it is much more effective than conventional circuits. 9 The treble control varies the high end response of the amplifier. 10 The reverb control determines the amount of delayed signal (reverb) blended into the output. This circuit is able to produce tremendous sustain and clarity by properly damping the driver coils of the reverb unit. The reverb is effective in both channels. 11 The Standby Switch removes the B+ supply from the output tubes while leaving the filament voltage on. This function keeps the tubes at operating temperature and allows for instant operation when the Standby switch is thrown. 12 The master volume control is very useful for obtaining a number of effects. The most common use of this control is for obtaining overdrive and sustain at low sound levels. The master volume control is the final gain determining element before the signal is fed into the output amplifier and could more accurately be called a “sensitivity” control. To obtain maximum overdrive and sustain, the individual channel volume controls should be set near maximum, and the output of the system should be adjusted with the ...
