NOISE TRIM/ dB LEVEL

 

Owner’s Manual

4.In the ‘System’ select mode with ‘Active View’ open; select ‘NOISE TRIM’ button which presents an option for raising or lowering the level on a per-zone basis as shown below. Each increment (54dB to 72dB) represents a 1dB increase or decrease from the base setting. Select required level button(s) from 54dB to 72dB in the box which activates 1dB ‘trip point’ – repeat settings for zones 1 through 8.

Setting example: If you select 57dB, 63dB and 69dB the masking noise level will raise 1dB as each ambient level is reached this will occur as each level is passed for a total of 3dB masking noise increase as the ambient level passes 69dB. The reverse will occur as the ambient level decreases past the selected ‘trip points’ so that the masking noise level returns to the base level setting.
