Descriere
The unconstrained dynamism of sound awakens fundamental instincts.
The AP-701 merges all the elements desired in a power amplifier at a high level, creating a new standard.
Independent left/right high-capacity toroidal core power supply transformers, discrete buffer amplifiers and two Ncore modules provide a complete dual mono structure from input to output. Moreover, the input stage of each channel has a fully-balanced design, so the dynamism of input signals is amplified as is, maximizing the innate performance of the speakers.
The cabinet is primarily comprised of 3mm-thick heavy metal plate but has a flexible structure to control vibration. By incorporating joints with suspension functions, the vibration frequency of the entire device is controlled to reproduce open and vibrant sound.
Complete dual mono design includes power supply
With two toroidal core power supply transformers and two Ncore modules, the extravagant circuitry has a complete dual mono structure from input to output. A dual mono structure, in which the channels are each completely mono, prevents interference between the left and right signals and achieves outstanding channel separation. This enables rich audio reproduction that provides a larger sound stage and more three dimensional sound.
High output with a practical maximum of 260 W + 260 W*1 / 170 W + 170 W*2
Hypex Ncore power amplifier modules realize both high efficiency and high audio quality. These two amplifier modules, which were tuned and designed specifically for TEAC, drive the speakers without losing any of the original musical expression, from delicate pianissimo to powerful fortissimo.
*1 4Ω *2 8Ω
Vibration control from flexible structure
The front, side and rear panels are secured with 3mm-thick heavy sheet metal as the primary material. Then, joints that provide suspension are used at the junctures of the front, side, rear and top panels. This enclosure with a flexible structure controls the vibration of the entire device to allow open and vibrant sound reproduction.
Fan-free design achieved with effective ventilation system
Despite the high output of this power amplifier, a fan-free design has been realized with circuit board placement calculated for airflow and precise layout of air inlets and outlets. Heat dispersion is increased by attaching the amplifier modules directly to the bottom panel. Along with the fin structure of the side panels, this reliably abates internal heat.
Extensive design for vibration control
A floating structure keeps the transformers, which can easily cause vibration, detached from the bottom panel. The form of the side panel fins, which provide heat dispersion, have been adjusted to eliminate vibration.
In order to suppress vibrations that affect audio quality thoroughly, the TEAC original pin-point feet that utlize a new mechanism are attached to the bottom panel with appropriate allowance, while a number of screws that fix the circuit boards to the chassis is minimized.
Numerous features for audio quality
The durability of input circuits is ensured by including slits between each connector. In addition, direct wiring without connectors is used from the input circuits to deliver input signals to the discrete buffer circuits without losing any of their clarity.
Low-profile body creates new potential in living spaces
A reduction in height, as well as the chassis depth, enables more freedom of placement. Whether in the living room or a workplace, you can use them to drive your favorite speakers as you like.

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.
