Automix is now standard in this new Deuce series. The Deuce power section is powered by Four extremely rugged and field proven RCA 6L6GC tubes (valves) in a push-pull paralleled circuit that delivers a very conser- vatively rated 120 watts RMS @ 5% THD. The massive power supply consists of a custom built power transformer delivering energy to series-stacked filter capacitors for the ultimate in reliability under field conditions. Because we have chosen to build a larger and better regulated power supply than found in competing units, the Deuce enjoys a substantial advantage in music power that is quite noticable when compared to ordinary amplifiers. The special output transformer matches the tubes to the speakers and allows conservative operation of the four output tubes well within the tube manual specifications. The Deuce is a fully professional portable amplification system utilizing the latest in circuitry to give you all the needed features in a reasonable package. The versatile Deuce series is available with several different speaker combinations to allow for personal speaker preferences. Your new Deuce features two channels, "Effects” and "Normal” with four inputs that function along with the Automix footswitch to allow you to play through either channel, both channels in parallel, both channels in series. Please read the explanation of each input and become familiar with the effects possible with the Automix footswitch. 1 The Effects, input places the signal frpm your instrument into the effects channel only. 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 effects channels, except that the internal circuitry automatically performs the patching function. When plugged into this jack, both normal and effects channel gain 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 gain control settings will yield an infinite variety of harmonic characteristics and sustain durations. These functions can be used in conjunction with the master gain 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 these required in some studio applications. EFFECTS CHANNEL 5 The effects channel gain control sets the gain of the effects channel 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. 6 The treble control varies the high end response of the effects channel. 7 The middle control enables the mid-range response to be tailored to give the amp that "punchy" sound so popular in today’s music. Experimentation with this unique middle circuit will show that it is much more effective than conventional circuits. 8 The bass control varies the amount of bass response in the system and is very effective in achieving a balanced tonal blend. 9 The depth control is used to vary the amount of amplitude modulation (tremolo) of the output signal. The operation of this control is conventional and should present no problem in adjusting for the desired effect. 10 The rate control determines the speed with which the signal is modulated. This control varies the speed of the tremolo master oscillator and should pr...
