Descriere
Tonewinner presents its AD-8300PA, an 11-channel power amplifier, allowing a home cinema integration, including Dolby Atmos systems. It delivers a consistent power with low distortion for an immersive and dynamic sound reproduction. Coupled with an audio/video preamplifier (sold separately), the AD-8300PA is an excellent solution for entering the world of high-end home theater.
Powerful 11-channel amplification
With the Tonewinner AD-8300PA you can enjoy an impressive amplification that is perfectly adjusted to the channels. Indeed, the left, right and center channels generally requiring more power, these operate at a higher current. They can thus deliver a power of 515W under 4Ω. As for the other 8 channels, they are not left out with a power of 205W under 4Ω.
Each channel benefits from an independent amplifier module – inspired by high-fidelity amplifier designs – and operates with high-power transistors providing 45A output current.
3000W Power supply
To provide such power, the AD-8300PA is equipped with a large 3000W switch mode power supply, which is capable of delivering high power requirements at any time. An essential basis to provide a dynamic and lively reproduction, adapting efficiently to the audio signal.
Balanced and single-ended connections
Simple and efficient, the connectivity of the Tonewinner AD-8300PA allows to connect a balanced or single-ended source. Indeed, each channel has an XLR (balanced) and RCA (single-ended) input connector. The output is made on speaker terminals accepting banana plugs. Moreover, for a practical integration, the amplifier is equipped with a 5V trigger input and output in Jack 3.5mm format. It is thus possible to automatically turn on and off the amplifier and its source thanks to a 5V signal.
Active cooling system
In order to promote good heat dissipation and therefore increased durability, the Tonewinner AD-8300PA integrates an active cooling system. Four fans are triggered when needed and adapt their speed according to the temperatures detected by the sensors of the device.
Protection circuit
In addition to this efficient cooling system and always with a view to durability and reliability, the amplifier embeds a complete protection circuit. It protects the AD-8300PA against short circuit, overload, overcurrent, overvoltage and overheating. If triggered, the short circuit, overvoltage and overcurrent protection can be reset with a button on the back of the unit.

Explicatii in ceea ce priveste rodajul echipamentelor, cat si al cablurilor, asezarea optima a echipamentelor in camera de auditie, importanta acusticii camerei si nu in ultimul rand sistemul de alimentare a intregului echipament:
PENTRU BOXE:
- 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, dar totodata la o distanta de cel putin 50cm fata de peretii laterali. Tineti cont de faptul ca orice piesa de mobilier din incapere, joaca rol de absorbtie fonica, dar si de difuzie fonica daca acestea din urma sunt din materiale ceramica sau oglinzi, geamuri sau alt material reflectorizant. In acest sens, gasiti pe blogul nostru, multiple articole care va pot ajuta
- 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 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 AMPLIFICATOARE, DAC-URI, PREAMPLIFICATOARE, RECEIVER STEREO & HOME CINEMA, SURSE DIGITALE AUDIO-VIDEO:
- 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.
- In ceea ce priveste echipamentul video precum videoproiector, TV, media player, blueray player, necesita un "rodaj" de cel putin 50 de ore. Lipsa acestuia nu va poate oferi maxim de performanta. "Rodajul" se efectueaza prin simpla utilizare a acestuia, intr-un mod conform specificatiilor mentionate de producator.
PENTRU CABLURI:
- 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.

Tratamentul Acustic si Izolarea Fonica
Pentru un sistem echilibrat, trebuie tinut cont pe langa asezarea corecta a boxelor in incapere, al echipamentelor, sistemul de alimentare al acestora, tinand cont de instalatia electrica a locatiei.
