Great price, Quick delivery, the document was very usefull A+++++++++++++++
;
Thank´s for your help, I already recived these manual from you
;
Thank you for your manual It has the basic things to and i use the Oszi for Longer Time.

Actually, I was looking for this information for 3 years!...now thanks to you, the manual is on my hands and of great help, cause I understand now where I was doing wrong connections and wires...excellent, I'll be back to you if in need, thank you.

This manual covers the main equipment features only. While it also includes the procedure for saving and loading from the now long obsolete memory cards it does not mention the how to operate with the optional floppy drive interface so I am still at a loss about how to use this! Note that there is a separate manual covering the MIDI interface and programming via the keyboard, not included in this download. You will also need to get hold of this if you want to use the MIDI interface properly. Basically there is little difference between this manual and the free to download manual for the similar PR60 model.
The T4 electro-optical device is the heart of the compressor and its gain reduction characteristics. Its unique characteristics affect the overall sound and character of the LA-610. In addition to the compression curve, the combination of the EL panel and the photo-cell determine the attack and release characteristics of the LA-610. This is one of the most important contributors to the sound of the LA-610. Unlike other compressors which allow the user to adjust these parameters, the attack and release of the LA-610 are completely determined by the T4. There are several important characteristics of the T4 which play crucial roles in the sound of the LA-610. The first is the attack. The LA-2A was the first electro-optical compressor to use an electro-luminescent panel for the light source. Previous attempts at electro-optical compression employed either neon or incandescent lights. Both of these took time to light up, and this delay resulted in slow attacks. The electro-luminescent panel resulted in a faster attack than exhibited by other contemporary devices. The next important aspect is that of the release of the compressor. This is determined almost entirely by the characteristics of the photo-cell. The LA-610 the uses the same cadmium-sulfide photo-cells. The first important aspect of the cell is its �two-stage decay�. After the light is removed from the cell, it releases quickly (40-80 milliseconds) to approximately half of its off resistance. The remainder of its release can take place over as much as several seconds. The next aspect is the �memory� of the cell. This results in two important aspects of the character of the LA-610. The amount of time it takes for the cell to recover after the light is removed depends on how long light had been shining on it and how bright the light. In the case of the LA-610 this results in behavior where the release time is slower if the unit has either been in compression for a while, or the amount of compression is large. This signal dependent release characteristic is critical to the sound of the unit. The amount of compression, as well as the compression threshold, is controlled by the �Peak Reduction� potentiometer. This potentiometer controls the gain of the side-chain circuit. The greater the gain of this circuit, the lower the threshold and the greater the amount of
