Specificatii | The A-300P MK2 Type UK is hand-built with extreme attention to detail, including point-to-point wiring. Point-to-point was in fact the way that the very best amps used to be manufactured back in the 1950s and '60s when cost was not the primary objective. Nowadays, most everything contains circuit boards instead, whereas with point-to-point wiring, the amplifier is much more dependable and far higher performing. The bottom line is that point-to-point wiring sounds better. It's one of the main reasons why all Cayin amplifiers sound like the classic tube greats from Marantz and McIntosh. In today's marketplace, products that feature point-to-point wiring normally are either at a very premium price point, or they feature sub-par workmanship - with Cayin, you simply have the best engineering at the best price. There are output taps for 4, 8 or 16 ohms. This allows you to fine-tune the sound that you desire. Switching is simple, and listening to the differences is a lot of fun. The A-300P MK2 also has two different NFB (Negative Feedback) settings : 0dB, sweeping soundcsapes for large scenes, large musical dynamic range, increased rhythm and timing -3dB, promotes a more intimate experience with warmer voices, strings, and percussion. The A-300P MK2 also has a unique design which allows for hum/noise adjustments. Adjust the Bias of the 300B's easily and quickly with the built in Bias gauge located on the top panel. Additional design points : A full-function aluminium infrared remote control. Power-on delay function (approximately 30 seconds), protects and extends life of the amp and valves. Power-down and memory function, remembers the last settings used. There is also removable valve cage included at no extra charge. The cage snaps into place simply, so that you can take it on and off with no problem. Keep it on if you wish to add the perfect protection for your tubes, or take it off to show what real, heavy-duty, beautifully engineered classic tube gear looks like.

- Pentru performante optime este necesara pozitionarea boxelor la o distanta de minim 30-40cm de peretele din spate pentru boxele cu bass-reflex in spate, pentru cele cu bass-reflex in fata, recomandam pozitionarea la o distanta de 10-20cm fata de peretele din spate.
- Boxele vor ajunge sa functioneze in parametrii recomandati de producator, dupa minim 50 de ore (ideal 100 ore) de functionare la volum mediu. In aceasta perioada de timp, de “rodaj a boxelor”, sunetul va fi la inceput ceva mai artificial, bass-ul nu va fi inca controlat, inaltele rigide iar vocile usor retinute, pe masura ce boxele vor functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate. Exista boxe care necesita un „rodaj” mai amplu de minim 300 de ore mai ales in cazul celor care au difuzoare de kevlar, carbon sau alte materiale de acest tip. Boxele care se „rodeaza” cel mai repede sunt cele care au difuzoare de celuloza.
- Pentru performante optime este necesar „rodarea” echipamentului, In functie de complexitatea componentelor din aparatul dumneavoastra acesta poate dura intre 30-200 ore.
- Rodajul se face la volum minim, fiind astfel suficient faptul ca acesta este alimentat corect conform manualului de utilizare la 220-230 Volti si trece semnal audio sau video dupa caz prin el.
- Echipamentul supus „rodajului” va ajunge sa functioneze in parametrii recomandati de producator, dupa perioada mai sus mentionata. In aceasta perioada de timp, de “rodaj”, sunetul va fi la inceput ceva mai artificial, bass-ul nu va fi inca controlat, inaltele rigide iar vocile usor retinute, pe masura ce echipamentul va functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate.
- Pentru performante optime este necesara „rodarea” cablurilor, In functie de complexitatea conductorului folosit, cat si geometriei acestuia, „rodajul” poate dura intre 30-100 ore.
- Rodajul se face la volum minim, fiind astfel suficient faptul ca va trece semnal audio sau video dupa caz prin el.
- Cablul supus „rodajului” va ajunge sa functioneze in parametrii recomandati de producator, dupa perioada mai sus mentionata. In aceasta perioada de timp, de “rodaj”, sunetul va fi la inceput ceva mai artificial, pe masura ce cablul va functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate.
