Abstract
The invention provides a preamplifier of electronic bass zone musical instrument electronic tubes, in particular to a serial signal preamplifier device for enriching the timbre of electronic bass zone musical instruments. This unit was connected in the signal path between the instrument and the amplifier using a standard 1/4 "input socket and a 1/4" output socket. Other effects processors may be placed before or after the preamplifier device. There is a volume control and an overload switch that employs a variable current source drive section to further reduce distortion and enrich the bass register timbre. The variable current drives the 1/2 plates of the 12AX7 tube with a 48vdc plate voltage in the overload position and a 40vdc plate voltage in the normal position. The use of the overload position causes premature failure of the 12AX7 valve and should therefore be economical. EBIP is useful for both solid state and tube amplifier applications.
Description
Technical field
The present invention relates to prime amplifier, relate in particular to a kind of electronic bass register musical instrument tube preamplifier.
Background technology
In nineteen sixty or before and after this, be obvious in the variation aspect the note amplifier tone color.Transistor is the earliest produced during this period in large quantities, and a kind of new technology for the manufacture of signal capacitor is developed out and is used.This new capacitor is less, more easily produces in enormous quantities.
At this moment, most of musical instrument amplifiers remain discharge-tube amplifier, but they bring into use modern signal capacitor.This is so large (for example not as its impact for musical instrument in the bass range of sound for the impact of instrument tamber in the high pitch range of sound, situation when playing by the amplifier of making before the signal capacitor of new technology comes out is compared, and the tone controller of bass guitar changes tone color no longer very significantly).
During the eighties in the later stage sixties 20th century to 20th century, most of musical instrument amplifiers all begin to be produced solid-state amplifier.This amplifier is not improved aspect tone color, but has improved manufacturing process.Before the eighties in 20th century, some amplifier and effect device manufacturer begin to adopt 12AX7 electron tube preamplifier circuit, and sort circuit is more abundant and to reduce aspect distortion be quite effective in the tone color that makes high pitch range of sound musical instrument.Bass range of sound musical instrument is not subject to the impact of same degree, and has developed the new method (such as beating string (slap) group (picking) etc.) of some performance electric bass.The further developing of digital effect processor improved the tone color of bass range of sound musical instrument to a certain extent, the preamplifier circuit that uses in people's (No. the 4644289th, United States Patent (USP)) patents such as Kennedy (Kennedy) (No. the 4672671st, United States Patent (USP)) and Kennedy utilizes the both sides of 12AX7 electron tube, has created a kind of more abundant and the tone color of distortion still less in almost the same with EBIP invention mode.
Invention has been described according to its preferred embodiment.Should be appreciated that, can modify to its form, configuration and numerical value, and not exceed scope of the present invention.
Summary of the invention
The invention provides a kind of electronic bass register musical instrument tube preamplifier, comprising: one has tandem signal adapting amplifier device, a fader and electron tube overload switch that 1/4 " input connects and is connected " output connects.
Described electronic bass register musical instrument tube preamplifier, also comprise: as described herein, in the 12AX7 preamplifier circuit, oil-paper signal capacitor and modern film " orange drips " the type capacitor that is situated between is used combinedly, this has enriched the tone color of bass range of sound musical instrument electronic signal, the output of wherein said modern film " orange drip " type capacitor-coupled to 1/2 12AX7, the Copper Foil oiled paper capacitor of two series connection are arranged in branch road and decoupling zero to ground.
Described electronic bass register musical instrument tube preamplifier also comprises a kind of use of electron tube overload switch, and described switch drives anode at 40vdc or under 48vdc voltage, with further reduction distortion and enrich tone color.
Described electronic bass register musical instrument tube preamplifier also comprises for the dc voltage power supply that drives 12AX7 type electron tube anode (general 153vdc).
Described electronic bass register musical instrument tube preamplifier also comprises the dc voltage power supply (6.3vdc or 12.6vdc) for 1/2 the well heater that drives 12AX7 type electron tube.
Described electronic bass register musical instrument tube preamplifier also comprises a kind of grounded metal box, and this grounded metal box holds the element that is used for eliminating RFI contained in this paper circuit theory diagrams.
This is a kind of very unique device, because it can enrich the tone color of bass guitar, especially enriches the tone color of hanging down octave and semitone on this musical instrument.For create abundanter tone color for other basses ranges of sound musical instrument for, it is also very effective.With oiled paper capacitor and film combinations use modern, that produce in enormous quantities as mentioned above, be particularly unique.
When S1 is in the overload position, but the distortion much less of the tone color of bass guitar under large volume.
Description of drawings
Fig. 1 means the schematic diagram of observing 9 pins on the 12AX7 electron tube from the bottom.Pin 1 and 3 is connected to anode, and pin 2 is connected to the grid on 12AX7 electron tube one side.Pin 6 and 8 is connected to anode, and pin 7 is connected to the grid on 12AX7 electron tube opposite side.Pin 4,5 and 9 is connected to heater strip.
Fig. 2 is the circuit theory sketch of EBIP.
Embodiment
Electronic bass range of sound prime amplifier (being known as hereinafter EBIP) is a kind of a kind of audio frequency preamplifier part of amplifying bass range of sound musical instrument for bass guitar and other.The basis of EBIP invention does not also lie in the circuit theory diagrams that it uses, but is the use at oiled paper capacitor, and in circuit, the thin film capacitor of these capacitors with the modern times is used in combination.Half of its use 12AX7 electron tube, and have one to allow this electron tube overload with the switch of further enhancing effect.(radio frequency interference: reason Radio frequency interference (RFI)), input socket must be isolated with ground due to RFI.
Since the 1950's, never produce oiled paper capacitor for the public's use, but today, their uses in high-end stereo set are risen.In circuit theory diagrams below, C1 is a kind of Mylar (Mai La) oiled paper capacitor.C2-C3 comprises the Copper Foil oil-filled paper condenser of the 0.47uf of two series connection.C4 is " orange drips (orange drop) " capacitors of a kind of modern times, and C5 is a kind of ceramic disc capacitor device (ceramic disc capacitor).All resistors all have 1/2 wattage.The B+ voltage of 153vdc is only a kind of typical voltage, is undertaken some by the numerical value to R1, R2 and R4 and regulates, and other voltage can be worked too.The can of a ground connection holds the electronic component of EBIP.
Described circuit comprises a fader in its final stage (last stage), this EBIP is designed to be held in place in signal circuit between musical instrument and amplifier.
The well heater that is used for described electron tube needs 6.3vdc or 12.6vdc voltage.Although heater circuit is not illustrated in circuit theory diagrams, be incorporated into this, as in this vacuum tube circuit the typical case exist.
EBIP is useful for solid-state and application discharge-tube amplifier.Especially for being effective especially for the bass guitar of some stringed musical instrument brand.Passive acoustic pickup is better, and other effect devices such as distorsion, sound pedal etc. also has improved musical sound.
Invention has been described according to its preferred embodiment.Should be appreciated that, can modify to its form, configuration and numerical value, and not exceed scope of the present invention.
