Audio input level for each of the sources should be equalized so that when switching channels the audio level remains constant This is accomplished in one of two ways e External to the MS 88 using the audio level control of each of the source devices or e Using the optional MS 88 input modules fitted with a stereo pot for each source Video gain is adjusted for each balanced pair destination zone depending on the length and transmission quality of the 4 pair cable used This adjustment is made with the video gain potentiometer in the balanced pair receiver BPRX 40 or BPRX 40V The level is ideally set with an oscilloscope but adequate results can be obtained simply by visualizing the image on its display device The receivers are factory adjusted to produce OdB gain over a 30M 98 unshielded flat cable Video equalization also adjusted in the balanced pair receiver with the video equalization pot corrects for the greater attention of the higher Operation chroma frequencies One again the factory adjustment is for a 30M 98 unshielded flat cable VR level in each of the mini emitters may be adjusted to match the sensitivity of each of the source I R receivers simply by moving the mini emitter around the surface of the devices I R receiver window until stable operation is achieved Unsatisfactory I R performance is usually due to having too much I R energy rather than not enough so moving the mini emitter away

8. f these connectors can drive a single or double I R mini emitter so up to 8 group A and 8 group B devices can be controlled If more devices need to be connected an external I R connecting block or distribution module can be used to increase the number of outputs I R activity is indicated by the two red LEDs called A and B External I R Inputs The 4 pin connector on the I R distribution module provides an input to the two I R groups A and B so that an external wired I R control console can input centralized commands to these two I R groups 7 High Level I R Outputs The 3 pin connector on the I R distribution module provides a high level output from the two I R groups A and B This output is suitable for driving external connecting blocks to increase the number of outputs It is not suitable for driving mini emitters and will destroy them very quickly e ZONE OUTPUT I R DISTRIBUTION MODULE l c SE El ii a e W mi ee BPRX 40 MS 88 TYPICAL MS 88 I R DISTRIBUTION wssavtoe0 Connections Video and audio source device outputs are connected to the input module or modules For balanced output modules either the RJ 45 modular connector or the removable 8 pin screw t
