nunu - myslis toto ?

nunu píše:Predzesilovac ktery dokaze pracovat do velmi male impedance, v konektoru ktery se strka do boxu odpor na snizeni impedance okolo 5k. Protoze predzesilovac to na takto spolehlive vybudi.

na mna treba polopate co treba kupit ? aky predzosilovac ? kam odpor ? do cesty na signal ? to impedanciu zvysi, nie ? cize menej vysok, atd...

nunu - pises do boxu. ale ja myslim nastrojovy kabel medzi gitarou a aparatom.

rastis : nemyslel on hlavu nechat v rezii a v studiu len box ?

pytkin - hej, tam by som si osobne problem nerobil - riadna hruba medena dvojlinka a malo by to ist bez vsetkeho... ale co v pripade trebars komba ?

som si predstavoval, ze pridem sem s trivialnym dotazom medzi samych odbornikov a majitelov studii a len si precitam jednoznacnu odpoved ... asi je to cele nejak inac ... hm.

rastis : ja neviem .. u nas tocime len hlas .. ale ak potrebujes , zavolam minarikovi a spytam sa , ako tocia s henrym

pytkin - to je presne to, co potrebujem - ako toci minarik s henrym

dik.

rastis : taakze .. Henry si tocil bicie a basy a podklady dake vo svojom studiu .. potom tam nastali dake problemy tak ostatne veci tocil u ivana .. Gitary tocil tak , ze mal gitaru priamo do pultu , od tial do zvukovky a amplitube na vstupe .. vypnuty direct monitoring cize pocuvali rovno z amplitube (oneskorene) .. aby sa mu lepsie hralo , tak mu primiesaval do zvuku cisty signal gitary (co je aj pocut v tom videu, myslel som ze je to nasnimala kamera priamo struny) .. ivan tocil rovno zvuk z amplitube a aj cistu gitaru pre istotu ..

Este som sa pytal ivana "Ako osetrit dlhy gitarovy kabel" .. povedal ze to bezne pouziva .. kabel z gitary ide do patchbayu v stene , v studiu vylezie z neho a ide do aparatu .. treba dat pozor na zemnenie .. A treba kvalitny kabel nerobi to ziadny problem .. ze v opuse aj 20m kable pouzivali a pohoda ..

takze amplitube to mi inak tvrdil aj fero griglak, ze doma si s amplitube toci veci... to len my na internete vieme, ze amplitube ja nahovno

dik pytkin.

skusal si sa pytat na zvukarina.cz ?

rastis : jasne .. tuna na fore vieme vsetci vsetko najlepsie !

Tim predzesilovacem jsem myslel cokoli co ma zesileni 1 tvrdy vystup. Jelikoz kdyz se to takto posili je zbytecne aby to pracovalo do takto vysoke impedance co ma vstup na kytaru, tak na konec kabelu mezi zem a zivy dat odpor okolo 5k.

nunu: to nebude fungovat vzdy dobre... preamp a cievka snimaca tvoria jeden RLC obvod a ked tam vrazis impedancny bufer, zmenis zvuk

a co tohle .... www.vhtamp.com/product-news/valvulator1.html. před pár lety se o tom dost mluvilo ... a mělo by to být super ...

VALVULATOR I VACUUM TUBE BUFFER/POWER SUPPLY
Your tone is important to you. You spend countless hours searching for the right guitar and amplifier combination to produce your sound. You experiment with the virtually limitless possibilities offered by today’s staggering array of stompboxes to embellish your sound. And in this process you have also discovered the frustrating loss of signal level, high frequency response and low end punch caused by effects pedals. This annoying degradation of tonal quality is caused by three things:

1) Loss of high frequency response due to cable capacitance.
2) Loss of signal level and high frequency response due to impedance effects.
3) Signal degradation caused by the design of the circuitry in the effects device.

The VALVULATOR I solves all three of these problems using a vacuum tube based Buffer circuit to change your guitar signal from high impedance to low impedance. This low impedance signal is better able to survive the trip from your instrument to your amplifier, including all of the detours in between. You will be amazed at the renewed responsiveness of your instrument as well as the effect on your playing. In addition, the VALVULATOR I input stage utilizes the same circuitry as that found in the input stage of most guitar amplifiers. This means you get the same dynamic feel from your instrument as you would if you were plugged directly into your amp!
Now that you have solved the signal loss dilemma, how do you keep your stompboxes operating at peak performance so your sound will always be there when you want it? The answer is to regulate the power going to the stompbox to insure that it will always be exactly the same voltage, no matter where you are. The Valvulator I provides four regulated and isolated outputs which will supply you with all of the clean regulated power you need to insure maximum signal output and frequency response from you pedal devices. And because the power supply outputs are individually isolated, you never have to worry about ground loop hum.
The VALVULATOR I runs on standard AC wall current, NO WALL WARTS, and is housed is a rugged steel chassis topped with a sleek stainless steel vented cover.
SIZE: 6-3/4”W X 3-1/2” H X 3” D.
WEIGHT: 3 pounds.

kekxik, ano.K lepsimu.

nunu: to pri gitarach nemozes nikdy povedat. single coil zapojeny do akejkolvek lampovej marshalky je cista prasacina, co sa tyka objektivneho pristupu ku kvalite. chcem povedat ze tvoje riesenie urcite zmeni zvuk
