Description

The LA1525SD hyper directional speaker can deliver a narrow beam of sound to a desired area while preserving silence around it, or allowing the co-existence of different sounds in the same space without mixing or interfering. The audio-beam created by LA1525SD can cut through noisy environments and deliver a headphone-like experience for the listener.

The LA1525SD speaker offers highly directional distribution of sound, which is reproduced clearly – without distortion – even at high volumes. The speaker itself is easy to use – you only need to connect the audio output of your source device (such as portable music player, laptop, DVD-player etc.) with the speaker and you are ready to go.

The LA1525SD hyper directional speaker can be mounted and used in three modes: Spotlight Mode, Virtual Speaker Mode and Sound Shower Mode.

In case the directional speaker is mounted on the same wall – on top or below the digital sign, it needs to point diagonally downwards or upwards respectively, in order for the audio beam to reach all possible heights of users.

The speaker is pointing towards the digital sign (or any other object that you want to draw attention to, by using directional sound) from which the sound beam bounces and arrives at the user indirectly. This situation makes it appear as if the sound originates from the object that it is being reflected from. The actual sound source remains hidden and is not noticed by the user.

Ideally, the directional speaker should be mounted on the ceiling, facing the floor. This creates a typical “sound-shower” situation, making the sound audible only at one spot in the room, while enabling it to be heard by people – of all heights – at the same spot. The sound-shower mode is also the best solution to minimize reflections of the sound and its audibility at different locations around the room. The sound starts to travel from the ceiling, bounces off the floor and is reflected back to the same spot at the ceiling, and so on.
