Resumen del manual
When the external footswitch is plugged in, the reverb return signal can be turned off or on by the reverb switch.) GRAPHIC EQ ASSIGN SWITCH (14) The graphic EQ assign switch on each channel allows “pre-programming" either or both channels to either go through or to bypass the graphic equalizer. This switching assign capability allows the operator to run one channel through the graphic while bypassing the other or to run both channels into or around the graphic. This assign capability takes on even greater importance when utilizing the AUTOMIX function since a tremendous range of variation can be obtained between the channels when one channel is bypassing the graphic while the other is fed into it. GRAPHIC EQUALIZER (15) The Musician amp features a very effective six-band active EQ circuit. Each band has been carefully selected for the proper frequency points, combining characteristics, and precise bandwidth (“Q”) to most effectively handle the spectrum covered by the guitar. This sophisticated equalization system has been created using the latest computer-aided design techniques and has resulted in a circuit that is not only exceptional in performance, but provides remarkable consistency across its frequency range. This equalizer is capable of a 30 dB range; i.e., 15 dB boost or 15 dB cut in each of the six bands. Each channel of the Musician has an assign switch (14) that allows the signal from the respective preamps to be sent either directly to the power amplifier or through the graphic. When this assign switch is in the “up” or “in” position, its signal is routed through the graphic; and when it's in the “down” or “out” positions, that channel's signal is routed directly to the power amp. The action of a graphic equalizer is generally well understood but several precautions should be taken to avoid overboosting the frequency extremes and thus creating difficulties. The graphic equalizer follows the channel equalization which is of substantial effect by itself, and when combined with the boost capability of the graphic, the range of boost becomes tremendous. When running the individual channel low, mid or high boost near full clockwise positions, one should generally avoid overboosting that particular range again in the graphic. This “double EQ” capability enables a fantastic amount of cut or boost but must be used wisely to avoid creating a "boomy" or “muffled” sound when too much low end is boosted, as well as creating “strident”, "screechy”, or noisy operation when too much high end is boosted. One should also be aware that the “double equalization" available also may cause problems in the extreme cut positions since cutting the EQ is the equivalent of reducing the gain for the affected frequency range. Experimentation will quickly illustrate the effectiveness of these equalization controls and generally, no difficulty whatsoever should be encountered. PATCH PANEL A full patch panel has been included to enable patching effects devices “in.line” and also to provide a frequency compensated low impedance output to drive recording or P.A. consoles directly without need of a “direct box" or other amp/mixer interface device. The Musician also features separate out/in jacks from each channel, thereby providing the capability for “stereo" operation or additional “inline" patching capability in each channel. PREAMP OUT (18) / POWER AMP IN (20) To allow “in line” patching of the various accessories, we have included a system of preamp out/power amp in jacks on the front panel. The preamp out is the straight preamp signal which is the sum of the outputs of the two channels plus reverb. The output level is approximately 2 Volts RMS and is a relatively low (600 Ohms) output impedance. The preamp out signal is connected through a switching contact to the power amp input jack and normally the preamp out is internally connected to the power amp's input. This circuit allows basically two modes of operation. When signal is taken from the preamp output, signal is also delivered to the internal power amplifier. If access to the internal power amplifier is needed or if some accessory device such as a noise gate, delay line, effects device, etc., is to be patched “in line”, then the preamp output signal must be connected to the auxiliary unit's input, while the auxiliary unit's output must be connected to the power amp input with shielded cables, thereby placing the auxiliary unit in series or “in line” with the normal signal path. Additional booster amp/speaker combinations should be patched using the preamp output. With this unique patching facility, many interesting effects can be accomplished. LINE OUT (19) Many attempts have been made over the years to patch the preamp circuitry of musical instrument amplifiers directly into recording or sound reinforcement mixing consoles. Most of these attempts have been unsuccessful and have resulted in players and soundmen having to utilize various forms of what is po...
