Component Engineering STRD-30S Manual 

the LS-30 and three conductor 22 Gauge wire is perfectly adequate for this purpose. The analog audio output from the pre-amp should be two shielded pairs, one for each channel. They can be individual cables, or two pairs in one jacket. Normal audio wire such as you would use for any other purpose is ideal. All of the terminal strips on the analog pre-amp can be unplugged at the pre-amp. The video output cable from the digital pre-amp in the sound head to the Dolby DA-10 or DA-20 is harder to deal with because it is ...

Rear of the LED assembly The LED assembly can now be mounted to the top of the standoff post by means of three 4-40 Flat Head screws. The Lateral Guide can also be reinstalled. The dual lens/pre-amp assembly should now be carefully eased onto the dowel pins in the adapter block and bolted in place. It is a good idea to have the digital video cable already plugged onto the digital pre-amp circuit board before you mount this assembly. Wiring Connect both of the LED’s to the outputs of the LS-30 power supply chassis. The small terminal strips at the rea ...

Analog focus and azimuth alignment Adjust the lateral guide roller until you have agreement between both the Cat. No. 97 and the “Buzz Track”. Adjust the lateral position of the LED for maximum output from both channels. The lateral guide position is important because it also establishes the correct position for reading the digital track. Move the LED in and out and vertically (rotationally) until you have achieved the maximum output from both channels. Gently tighten the clamp screw of the analog mount. Try not to overdo the screw tightening so that the t ...

Adjust the analog LED Alignment Preliminary: Because you are dealing with two soundtracks, and because you are starting from scratch, you will have to go back and forth between the two media while you get everything optimized. Mostly, this means the adjustment of the two light sources. The good news is that as already mentioned, the two optical assemblies have been preset so that you have a beginning point. Their focus and azimuth may not be exactly correct for your sound head, but they will be close enough to get you started. Loosen the clamp screw of bot ...

the reader to adjust for the flattest perf trace and the lowest error rate on the processor display. Large azimuth errors are seen as a tipping of the ‘scope sprocket hole trace. The axis will be the center of the displayed perf trace. The DRAS azimuth number you are looking for is as close to zero as possible. Retighten the clamp screw when both focus and azimuth have been optimized. Final: As a final check run Dolby Cat. 69T and observe both digital and analog levels and the digital error rate. Analog: You can go back a ...
