Продаю микрофонный ( линейный DI )ламповый преамп Dizengoff D4 , сделан прибор в Чикаго США !
Заказывал его со штатов и вёз сюда - цены так же можете посмотреть в интернете ( это 799$ + доставка )Редкий зверь в наших краях - пока вообще не встречал таких в СНГ Построен по прототипу консолей 60-х годов вот ссыль какие лампы и что это вообще за прибор

Включался от силы раз 10 , причина продажи - нужен более универсальный инструмент и буду заказывать Slate Digital VMR (S).
Для тех кто реально заинтересован и в Киеве могу подвезти для тестов !!!
Вот ссылки на него в ютубе :

Вставлю ещё описание на англ:
Dizengoff Audio’s D4 is a single-channel mic preamp based on a design created by EMI’s in-house Recording Engineering Development Department, as part of the development of the REDD.51 tube console. Although also installed in various other EMI studios, the REDD.51 was made famous by its tenure in Abbey Road’s Studio 2 from 1964 to ’68, where it was used to record the Beatles and Pink Floyd, amongst others. Dizengoff’s aim “to build affordable tributes to classic recording gear based on the original circuitry but with a Chicago-inspired twist” has resulted in their D4 being a re-engineered and expanded version of the original EMI design, rather than an exact clone.
On the left of the 2U front panel is a vertical line of three toggle switches that activate a 20dB input pad, reverse the polarity of the input signal and route 48V phantom power to the rear-panel transformer-balanced mic input, which is located next to the transformer-balanced line-level output. A quarter-inch jack socket, sitting just below the toggle switches provides a high-impedance instrument DI input.
The original EMI-designed circuit provided only three switched input gain settings (+36, +40 and +46 dB), but the D4 offers many more: there are 12 steps between +20 and +60 dB. These rise in five +4dB steps from +20 to +40 dB, followed by three +4dB steps from+46 to +56 dB and two final +2dB steps to the maximum +60dB. The Trim control, carried over from the original, enables you to increase or decrease gain by approximately ±2-4 dB at each step, the precise amount depending on the position of the Gain switch, and this gives the unit an effective input gain range of +16 to +62 dB.
The D4’s circuitry consists of two circuit boards, one carrying the power supply, with its Nippon Steel R-core mains transformer, and the other the two signal transformers, twin tubes and associated audio circuitry. The input and output transformers are based around the specifications of the originals but were custom designed, and are being made in Chicago as part of Dizengoff’s laudable efforts to use as many locally sourced components as possible. The overall build quality is exceptional, and the components are of a uniformly high standard.
The tube complement comprises an EF86 low-noise pentode in its first stage, followed by a E88CC double triode driving the output, and both appear to be of modern Russian manufacture. The manual suggests that NOS versions of either valve or their equivalents could be fitted as upgrades, whilst warning that, due to the unit’s high supply voltage, an ECC88 cannot be used to replace an E88CC. But before spending an additional £150 or so (at today’s prices) on NOS replacements, it’s probably worth noting that the D4 has a specified frequency response of 20Hz to 60kHz, a signal-to-noise ratio of -90dB at +60dB of gain (10-24kHz bandwidth) and a THD+N figure of one percent at 1kHz (+4dBu, 10-24 kHz bandwidth).
Like its hi-fi equivalents, a tube-based microphone preamp is capable of displaying a high level of fidelity, and the Dizengoff D4 is no exception to that rule. With an AKG C414 B-ULS condenser mic, the D4 produced a clear, detailed delivery that possessed a solid weight in the bass, precise delineation in the mid-range and a crisply etched treble across a range of acoustic stringe
