TruVoicelift TeamConnect Ceiling 2 Distribution of Sound with TeamConnect Ceiling 2 Zone Control You can ensure even distribution of sound with no feedback by splitting the loudspeakers and microphones into different zones within the room. The quantity and locations of the zones will be determined by the size and acoustics of the room, the number of listeners, the distance between the microphones and the loudspeakers, and the polar pattern of the chosen loudspeaker. To determine how loud your system needs to be for even coverage and speech intelligibility in the room, you first need to calculate the potential acoustic gain (PAG) and the needed acoustic gain (NAG) (see „PAG/NAG Calculation"). Example: If the presenter is at the front of the room, the sound can be distributed evenly by increasing the loudspeaker level as you move from this zone to the furthest listener. An ideal mix-minus is calculated in the DSP system based on the distances between the person speaking and the listeners, and a matrix mixer ensures that a wellbalanced mix is distributed to each zone. Mix-minus refers to the muting or lowering of loudspeaker volume in zones that have active microphones, eliminating the potential for feedback. Mix-minus is also used when incorporating more than one TeamConnect Ceiling 2 microphone zone in order to enable audience participation. Sound Control When multiple open microphones are operated at the same time, the systems must be balanced against each other. As interactions between presenters and the audience can often be lively, it is important to manage the interaction between microphones, loudspeakers and the persons speaking. To manage active microphones and loudspeakers, we recommend using an external DSP system to control the zones with automatic mixers. This both improves intelligibility and scales up GBF significantly. To give each loudspeaker zone the desired sub-mix, automixers are complimented by powerful matrix mixers. Equalizers (EQ) and notch filters can be used to fine-tune mixed signals to the given room size. Presenter sound control Audience sound control Pick-up of audience voices AN 1300 v1.1 | 01/22
