Ретро красота

title

 

Господството на цифровите технологии, онлайн стрийминга на музика и опитите за вкарване на усилватели клас D в нишата на хай-енд аудиото не изместиха класиката от сърцата на аудиофилите. Забелязва се завръщане към дизайна на 70-те, признак, че носталгията по началните години на Hi-FI техниката все още е жива у верните почитатели. За младите ретрото е просто мода. Устойчивото нарастване на търсенето и предлагането на грамофонни плочи е феномен, който преди 10 години щеше да ни се струва абсурден, но днес е охотно приет от аудио индустрията, която набързо произведе невероятно разнообразие от грамофони и аксесоари за тях, а звукозаписната индустрия се завърна към производството на плочи като днес всеки държащ на името си музикант издава албуми и на винил.
Ретро манията е удобен повод някои позабравени фирми да се завърнат в нишата на стерео аудиото с продукти, напомнящи златните им години. Ще ви представим няколко нови модела стерео усилватели, чийто външен вид със сигурност предизвиква фетишистка тръпка у повечето аудиофили.

FREQUENCY RESPONSE: (-3dB points at 1 watt) 0.7Hz to 75 kHz.
INPUT SENSITIVITY: 1.4V RMS BAL for rated output. (25 dB Bal gain into 8 ohms.)
INPUT IMPEDANCE: 300K ohms Balanced.
OUTPUT POLARITY: Non-inverting. Balanced input pin 2+ (IEC-268).
OUTPUT REGULATION: Approximately 1.0dB 8 ohm load to open circuit (Damping factor approximately 8).
OVERALL NEGATIVE FEEDBACK: 15dB.
SLEW RATE: 10 volts/microsecond.
RISE TIME: 4.0 microseconds.
HUM & NOISE: Less than 0.06mV RMS – 112dB below rated output (IHF weighted, input shorted).
POWER SUPPLY ENERGY STORAGE: Approximately 520 joules.
POWER REQUIREMENTS: 105-125VAC 60Hz (210-250VAC 50Hz) 410 watts at rated output, 500 watts maximum, 230 watts idle.
TUBES REQUIRED: 2 – Matched pair KT150 – Power Output; 2 – 6H30 Driver.
