Resumen del manual
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 provide any speed desired for modern music. NORMAL CHANNEL 11 The normal channel gain control determines the sensitivity of the normal channel preamp. This control works in the same way as the effects channel gain control. 12 The normal channel treble control varies the high end response of the normal channel preamp. 13 The normal channel bass control varies the amount of low-end response in the normal channel preamp. MASTER SECTION 14 The master reverb control determines the amount of delayed signal (reverb) blended into the output. The master reverb control is effective on both channels and is remotely switchable by use of the Automix footswitch. 15 The master gain 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. Another valuable use for this control Is for controlling the response and noise of the amp in a recording studio. The master gain 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 master volume control. 16 The pilot light indicates when the electrical supply (mains) is supplying power to the amplifier. 17 The fuse is located within the cap of the fuse holder and should be replaced with one of the proper value if it should fail. It is necessary that the proper value fuse be used to avoid damage to the equipment and to avoid voiding warranty. If your amplifier repeatedly blows fuses, the unit should be taken to a qualified service center for repair. 18 The line power switch is of the three position type with the center position being off. The three position switch has two ON positions, one of which is used to ground the amplifier properly. One of the ON positions will yield the least hum or popping when the instrument is touched and this is the position that should be used. For your safety, we have incorporated a 3 wire line (mains) cable with a grounding lug. It is not advisable to remove the ground pin under any circumstances. If it is necessary to use the amp with the old two prong sockets, a suitable adaptor should be used. Much less noise and greatly reduced shock hazard exists when the amp is operated with the proper grounded receptacle. 19 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. 20 The main speaker output jack is where the main speaker must be plugged in. The output in-pedance of this jack is 4 ohms. 21 The external speaker ]ack is designed to allow use of an additional speaker system with the Deuce. This jack does not become operational until the main jack has been connected to a speaker. Due to a special switching jack which connects a separate 2 ohm tap on the output transformer, a 4 ohm load may also be connected into this jack—thus allowing the amp to put out full power into a total impedance of 2 ohms when an extension speaker is desired. The output impedance of the Deuce is 4 ohms when the main speaker jack is used and 2 ohms when both are used. NOTE: No less than a 4 ohm speaker system should ever be connected to either speaker jack. 22 A “Din” Socket is located on the back panel for the Automix footswitch. Care should be taken to properly mate the connectors of the footswitch plug with the respective socket holes. FOOTSWITCH Selector Button As the name implies, the selector button allows you to select between the normal and bright channels. This button is functional with your instrument plugged into either the series or parallel input. Combiner Button The combiner button deactivates the selector button and allows both channels to be in the circuit at one time. The selector button becomes inoperative as soon as the combiner button is depressed. Reverb Button The reverb button activates reverb on both channels. Tremolo Button The tremolo button activates tremolo on the effects channel_ NEVER OPERATE THE AMPLIFIER WITHOUT A SPEAKER LOAD!! This amp is equipped with a shorting system on the main output jack t...
