Page 13: Selecting Channel / Frequency Setting
Only change the fine tuning (frequency offset) in circumstances where it is absolutely necessary to do so. Once you have changed it, all televisions con- nected to the cable system will need to be calibrated by means of fine tuning to match it. - 13 - HMM 480 / HMM 480 OIRT / HMS 480... -
Page 14: Setting The Output Frequency
Bx 2A OUTPUT Level 0 dB • Use the test receiver to measure the output level of the channel strip and make note of the value. • When adjusting the other channel strip, compare its value with the value noted for the first channel strip. • Measure the output levels of the other modulators used and make notes of their values. - 14 - HMM 480 / HMM 480 OIRT / HMS 480... -
Page 15: Selecting The Audio Signal
C t i n g t h e au d i o s i g n a l In this menu, you can select when using – HMS 480 between the audio settings "STEREO" or "DUAL" or when using – HMM 480 / OIRT between mono audio (Mono L) and the composite signal of the audio signals (Mono L + R). -
Page 16: Final Procedures
• Test the output level of the output collector according to the STC 160 assem- bly instructions and set the output level required for the cable system. • Mount the base plate and the front cover (see STC 160 assembly instruc- tions). - 16 - HMM 480 / HMM 480 OIRT / HMS 480... -
