Wiring method of Ceiling Speakers

June 16, 2022

When installing the ceiling speaker, the opening distance will be considered, so before installation, you must first check the peripheral parameters of the ceiling speaker and make holes on the ceiling. Usually there are 4 inches, 5 inches, and 6 inches. The opening diameter can be opened according to the opening size specified in the instructions of each ceiling speaker or the manufacturer's atlas. In actual construction, it can be slightly larger, which is more convenient for installation.

Constant pressure ceiling loudspeaker wire usually uses RVS2*1.5 twisted pair wire for indoor iron pipe, and RVV2*1.5 sheath wire is usually used outdoors. If the project site is large, in order to reduce line loss, thicker signal wire can be used. Various external interference signals at the scene are large and the distance is relatively long. The RVVP sheathed cable with shielding can be used, which can sometimes solve various uncertain problems such as noise and humming. For public broadcasts that require fire-fighting broadcast linkage with a strong-cut volume control, a separate power cord for 24V strong-cut triggering needs to be laid.

In the installation of multiple ceilings, the connections between the speakers are wired in parallel. It is necessary to distinguish the positive and negative poles and the 100V70V binding posts, do not confuse them, the power of the binding posts must correspond to the power amplifier. If the ceiling speaker is connected to 70V, then the power amplifier cannot be connected to 100V. In short, the power of the audio should not be less than the power of the power amplifier, otherwise the audio will be at risk of burning out.
