The set comes in 2 parts, the case (the heart) and a remote the size of a good book. On the back of the rackmount unit, 1 XLR (the only) input and 2 other times this XLR female to stereo output jack and an external clock (synchronization possible with other effects). Not forgetting of course the RS232 connector to connect the remote.
The reverb works on 16 bits with a sampling frequency of 44.1kHz.
Use to type of machine from the early 80's can be scary, at first, but once one has the remote in hand, we are quickly reassured by this remote effects of news in full any kind thanks to its large LCD display and its many commands. Everything is arranged in a logical and perfectly understandable for a novice not hear ..
The sound is clear, without particular resonance, clean and very soft, and frankly light years away from other productions YAMAHA (even today).
And no offense to the purists, as well as good reverbs QUANTEC, EMT, and AMS of the same period. At finesse, only LEXICON 224 XL can do better, while remaining within the same category and the same time.
A great reverb and really vintage even if that word is too often abused and used indiscriminately, there for the shot, it's real vintage.
Quite difficult to find time (especially in good condition).
Last little detail, new value in 1983: 100 000 francs ..
