Anleitung Zusammenfassung
Experimentation with, the unique middle circuit will show that it is much more effective than conventional circuits. (8) The treble control varies the high end response of the amplifier. (9) 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. (10) 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. Another valuable use for this control is for controlling the response and noise of the amp in a recording studio. 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 master volume control. You will discover that many different and pleasing harmonic effects can be obtained by trying different settings of the tone, volume, and master volume controls. It has been found that when operating the amp in the overdriven condition, lower settings of the treble control tend to give a smoother "natural distortion characteristic". The normal background noise (hiss, hum. etc.) can be very effectively controlled for recording studio applications by use of the master volume control. To reduce these noises, reduce the setting of the master volume control. 01) The pilot light indicates when the electrical supply (mains) is supplying power to the amplifier. (12) The Standby switch allows the operator to cut the amp off without shutting off the tube filaments. This places the amp in a "Standby" mode which eleminates the warm up time for the tube filaments when the amp is switched on. (13) The on/off switch is a two position switch which cuts the amp on and off. (14) 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 the warranty. If your amplifier repeatedly blows fuses, the unit should be taken to a qualified service center for repair. (15) The ground switch is a two position switch which is used to ground the amplifier properly. One of the positions will yeild the least hum or popping when the instrument is touched, and this is the position that should be used. (16) 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. (17) The main speaker output jack #1 is a switching type and must be plugged into before the external speaker jack #2 becomes functional. The output impedance of these amplifiers is 4 ohms TOTAL. Other load impedances can be used with a sacrifice in performance. It is not recommended that less than a 2 ohm load be used on these amps to avoid undue loading of the output tubes. (18) The external speaker jack #2 is designed to allow use of additional speaker systems with the amp. This jack does not become operational until the main jack #1 has been connected to a speaker. It is advisable to note that we have provided additional power in this amp to drive more than one speaker system. This additional power could be more than one speaker system can handle. These and all other high power tube type amplifiers must be used in the proper manner to avoid damage to tubes and other internal components. Below are several instructions that MUST be followed when operating high powered tube type equipment. A. NEVER OPERATE THE AMPLIFIER WITHOUT A SPEAKER LOAD!! This amp is equipped with a shorting system on the main output jack to help protect against accidentally turning on the amp without a load. If the speaker patch cord is plugged into the amp, but not connected to the speakers, the amp is NOT loaded anc could cause problems if the amp is turned on and operatec in this manner. The natural induct...
