[. . . ] The center channel speaker should be located on axis with the reference monitoring position and both the left and right surround channel speakers should be at an angle of 110 degrees from the center line. In most applications, surrounds used for music are placed at the same height as the front speakers for a direct sound field. See Figure 1 Satellite Speaker Placement - FILM / POST PRODUCTION 110° FIGURE 1 B C L R D= B 30° Although the above recommendations should work equally well for both film and music production, there may be situations where a more "film" optimized setup is desirable. To correctly relate audio to picture, the recommended angle between left and right speakers is 45 degrees. This narrower monitoring angle should still yield a very satisfactory stereo image. As with the "music" setup, the center channel speaker, should still be located on axis with the reference monitoring position. Unlike music surrounds, which tend to be direct in nature, film surrounds are usually positioned for a more diffused sound field, to simulate the effect of an array of surround speakers used in a theater. For a single pair of surrounds, this can be accomplished by placing them two feet above seated ear height, to the side of the monitoring position and slightly behind the mix position. For larger rooms, it may also be desirable to use multiple surround speakers as an "array". Satellite Speaker Monitoring Height Recommendations It is recommended that all of the satellite speakers be placed at or about seated ear height, as shown in Figure 2. If it is not possible to place the speakers at or about seated ear height, please aim the speakers at the monitoring position. Subwoofer Speaker Placement Although you have great flexibility in positioning a subwoofer, a good starting point is centered between the left and right satellite speakers. This could be under the console, behind the console, etc. Placing the subwoofer closer to a corner or wall will increase acoustic efficiency and may yield better acoustic response in many situations. However, because of the many variables that relate to "in-room" subwoofer performance, we highly recommend experimenting with subwoofer placement. Visit the Blue Sky website for more detailed and specific recommendations. Speaker placement recommendations, with regard to these types of installations, vary greatly on the end users' goals and surround philosophy. For more specific information regarding your particular installation, please do not hesitate to contact Blue Sky directly. www. abluesky. com LS RS Reference Monitoring Position SPEAKER PLACEMENT AS DOCUMENTED IN RECOMMENDATION ITU-R BS. 775-1 FIGURE 2 Center of the tweeter Center of the woofer Mid-point of the woofer and tweeter MONITORING HEIGHT RECOMMENDATIONS Page 10 · User Manual · 5. 1 Speaker Placement BMC MK III USER MANUAL · 10 · SYSTEM WIRING INFORMATION & DIAGRAM Use high-quality, shielded cables to connect your console, workstation or other sources to your BMC MK III and monitoring system. Foil-shielded cables, such as Belden 8451, 8761, or 9501 should do quite well. Other high quality cables are available and those that incorporate better shielding will yield an overall higher noise rejection, lowering your systems susceptibility to external interference. Another important tip to keep in mind when wiring your system is to route all line level cables away from the AC and other power sources, this will reduce the probability of having AC hum emanating from your monitoring system. 5. 1 Channel Output From Console or Workstation bass management controller MK III 5. 1 Channel Output From the BMC going to the monitoring system.
