Descriere
The PE-505 is a phono equalizing amplifier with dual monaural and fully-balanced input/output circuits that support balanced MC input.
The development of the PE-505 was achieved by relying on TEAC’s audio technology expertise, focusing on recording and playback, with the goal of accurately reproducing the original intent of the recording producers. The PE-505 will amplify even very faint audio signals picked up by the cartridge, process them without coloration, and then deliver them faithfully in order to keep the listener as close as possible to the original sound that was played before it was engraved on the master disc.
The high precision RIAA correction circuit, as well as both DECCA and COLUMBIA curves are supported. In addition, selectable load resistance for MC cartridges and load capacity for MM cartridges are present; allowing users to optimize the settings for the type of cartridge used and for the condition of the record.
From the head amplifier to the equalizing amplifier sections to the buffer amplifier section on the final output stage; the PE-505 employs a fully-balanced circuit design throughout all stages that amplifies, equalizes, and maintains signal purity of even the most extremely faint audio signals picked up by a cartridge.
Even unbalanced signal on the conventional RCA input is converted to the differential processing mode right after the input terminals.
Absorbing errors on the balanced output, the differential output equalizing circuit delivers a more accurate audio signal. The differential output circuit that cross-multiplied the hot and cold outputs each other. As the result, both signals are equalized for a pure and natural audio signal delivery.
A newly developed NF-type equalizing amplifier achieves less than ±0.05dB of RIAA deviation.
(20Hz to 20kHz)
The PE-505 achieves 106dB on the RCA input*1, and 86dB on the XLR input*2, while the residual noise voltage reaches 10μV on the MM and 85μV on the MC*3 which are sophisticated.
*1 MM *2 MC *3 XLR input
As well as the modern RIAA curve, individual curves on monaural records from DECCA and COLUMBIA issued before the RIAA curve was defined in 1955 are also supported.
The PE-505 equips switchable load-capacity for MM cartridges and switchable load-resistance for MC cartridges. Furthermore, the load-resistance measuring function allows users to select an appropriate load-resistance by pressing the MEASURE key on the front panel to show the total load-resistance value including cable resistance on the gauge.
Also, the Subsonic function shows subsonic signals less than 6Hz on the gauge, while the subsonic filter (17Hz, -24dB/octave) cuts unnecessary low frequency out of the hearing range.
With the quick demagnetize function, both magnetized iron cores of MC cartridges and the step-up transformer are demagnetized by playing back a vinyl record for as short as 30 seconds with the DEMAG position.

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.
