SOLAR 4 User Guide English MC35732UNPeng SOLAR 4 REO SOLAR PREAMPLIFIER USER GUIDE Your new SOLAR 4 is a preamplifier for optical sound signal reproduction of 16mm and 35mm films The audio stereo signal delivered by the photoelectric cells sc is processed optimally and if necessary denoised by the integrated dynamic noise reduction DNR push button In the case of movies providing mono tone we recommend selecting mo mono mode FORMAT push button ensuring channel identity and improved signal integrity Above all a higher degree of noise attenuation is provided in mono mode With its aux connectors the SOLAR 4 provides an additional stereo input for music and speech messages SOURCE push button After the HiFi equipment has been adjusted to the desired movie volume the aux volume level can be adapted using the level aux knob on the rear Therefore it is quite simple to switch from movie sound to music and vice versa without the neces sity of correcting the volume level Furthermore you can store SOURCE DNR and FORMAT settings that will be restored after every power up Please read the entire guide attentively before putting the SOLAR 4 into operation imp gain hf g imp gainhf g levelL level R DNR FORMAT S Qo HHgsg GAB 0 amp amp photo cell z optical sound level control and DNR on off FORMAT

7. ly low nominal signal level we recommend readjust ing the level L and level R settings so that the level indicators flash occasionally during periods of increased signal level This is a necessary sign to show that the DNR circuit is working with a suitable signal level to achieve an optimal result in noise attenuation After playback of a film with an exceptionally high or exceptionally low nominal sig nal level you should readjust the level L and level R knobs to middle position line marks up If you do not adapt the system manually to extreme signal levels it may affect the sound quality An effective signal level that is too high may reduce the ef fectiveness of the noise reduction an effective signal level that is too low may result in a total attenuation of low sound sequences With the SOLAR 4 being adjusted correctly in every way the optical sound repro duction reaches a high degree of naturalness and clarity 5 12 aux volume CD e g level aux photoelectric cell signal connection diagram The SOLAR 4 is suitable for mono ste reo and Dolby Surround sound for Dolby Surround you need to add a de coder Z Z high level input AUX power pack CD TUNER A HiFi equipment with Dolby Surround decoder and equalizer if necessary 6 12 puueyo yu sio e5 Joyes pu uonesJado IPUI 949 pue 0 1U09 99 9199 13 puueyo 3491 s103e9 IPUI A9 PUL
