Optimum subwoofer performance may be obtained by the use of two subwoofers

• AV Applications (film & video)

The standard Left / Right angle for film and TV is 45°. If your loudspeakers have to be installed

behind a perforated screen, a 45° angle positioning will give the best results. For sound for picture

applications, you may also consider a surround array of 4 (or more) surround speakers.

Recommended calibration levels are the following :

Left/right/Center : 75 dBC per channel

Surround Speaker : 72 dBC each

Subwoofer : for film mixing, the subwoofer level has an extra 10dB of headroom. This means that the

subwoofer level should be calibrated accordingly i.e. 85 dB in band.

7 Troubleshooting

Please check that the power switch is set on the ON position and that the mains cable is properly
