DBX 166XL Compressor / Limiter / Gate, made in China


Link: dbxpro

Most compressor/gates provide less than musical compression, coupled with gating that swallows transients—or closes early, cutting off decay and reverb tails. The superb engineering in the 166XL ensures that both its compression and gating provide versatility and excellent sonic performance in situations where other compressor/gates typically produce undesirable processing artifacts.

When using the 166XL’s Attack and Release controls, artists and engineers will find that the center settings deliver classic dbx compression, while the full control range produces voicings that extend from slow “leveling” to aggressive “peak” limiting.The 166XL’s advanced gate circuitry uses a completely new, program-dependent timing algorithm to produce ultra-smooth release characteristics—even with complex signals, such as voice or reverb decays. dbx engineers went on to take advantage of the wide dynamic range and high precision of the dbx V1 VCA to design in an extra-wide threshold range and ensure top gating performance for each application.

Tais 20 [Таис 20], December 1993, made in Belarus ¿¿





Синтезатор с автоакомпанементом совершенно случайно, и пожалуй ненадолго, но появился.  По истории человека, принесшего его, образец попал к нему со сборки Минского приборостроительного Завода (иначе называемый Завод Ленина, БелВар, Амкодор-Белвар и т.д.) Причем известен инженер, участвовавший в разработке и создании. Ближайшее родство с Лель 24 ¿¿, серийник отбит 00005, датирован Декабрем 1993 года. То есть, можно громко и сознательно заявить "Экспериментальный образец". Пустует одна "каретка" для микросхемы, позже выясним оставили для сервис-центра разъем под "тестирование", или налицо недостача "драг металлов".

Фото лучшего качества как всегда в скором времени, ток не надо душить :)))

CIAO! 
  

Elektronika Venta-Overdrive PE-12 [Электроника Venta-Overdrive ПЭ-12], 1990, made in USSR




A later (post-communist) Russian overdrive stompbox. The full name of the effect (according to the manual) is "Overdrive Electronika PE-12". That means it was made at the same place as Electronika PE-11 Flanger (the name suggests these two should be close relatives), and Electronika FL-01 Flanger - an earlier example of the same flanger. Sadly, we don't have the schematics scanned. 

Elektronika Compressor-Sustainer [Электроника Компрессор-Сустейнер гитарный эффект, арт. 2113р], May 1983, made in USSR




This is a nameless Compressor/Sustainer made in USSR. Controls on this pedal are distortion, sustain, soft/hard and effect on. In and out sockets are DIN5 five-pin, just like on all the Soviet guitars and effects.

Схематически данный эффект представляет из себя часть Джет-Фазера от той же Электроника.

Elektronika Fazer-2 [Электроника Фазер-2 гитарный эффект, арт. 2110р], July 1983, made in USSR




Fuzz/Vibrato effect from the older Electronika line. Made in USSR in the late 70's.

The controls knobs are labelled 'speed' and 'resonance', and the switch has 'fazer' and 'vibrato' positions. The jacks on the right side are in and out, and the left side features external power supply input.
