How large is a ceiling-mounted campus wooden speaker in the public address system?

It is better to specify the plan according to the on-site environment. If you do not observe the actual on-site environment, it is difficult to make an ideal selection and horn placement plan. For the installation distance between ceiling speakers, please refer to this article in the industry: every two The distance between the two speakers is twice the distance from the speaker to the ground, and this installation method usually meets the requirement of uniform sound playback in the whole audience. Configure the power of the ceiling speakers and the layout of the ceiling speakers according to different venue environments. It is necessary to consider the location of the listeners in the entire venue, such as whether they often move, stand or sit more, and the entire venue environment Some factors such as the size of the background noise. The sensitivity level of the ceiling loudspeaker is between 88~93dB; the rated power is 3~10W. Calculated by 90dB/8W, the sound pressure level at 8m away from the speaker is about 81dB. The above calculation does not consider the contribution of the early reflection sound group. Indoors, the contribution of early reflected sound groups and adjacent speakers can increase the sound pressure level by about 2 to 3 dB. According to the above approximate calculations, in venues with ceilings no higher than 3m, ceiling speakers can be arranged evenly at a distance of 5-8m from each other. If you consider background music without considering emergency broadcasts, the distance can be increased to 8-12m.

Campus wooden speaker effect

The audio-visual room uses a speaker layout plan with a full set of surround sound speakers. Of course, this is only an ideal. In reality, the rooms we can get are leftovers selected by others. For example, we are always in the wine cellar, gymnasium. People from behind, indoor golf and even cigars, etc. come to the theater, there are even aisles between stairs and elevators, a loft with a sloping roof on the top floor, etc., which reflects the strong surround sound of the theater. Wall mounting of all speakers>Top mounting of surround speakers>Wall mounting of center speakers>Top mounting of all speakers. Each company has its own ideas about the importance of the arrangement of the center speaker. I think the importance of the center speaker is more important, which also emphasizes the importance of the position of the center speaker, which is relative to the center speaker. The front left and right speakers may also be regarded as surround speakers. We use transparent screens as much as possible. The starting point is to emphasize the importance of the center position, that is, the position of the horizontal height. When the screen is too large (for example, a theater) Add speaker fill between the center and left and right speakers. The idea is to widen the center instead of widening the left and right speakers. If you are a player, the use of multi-channel surround sound is always more direct than virtual surround sound. In any case, you must adjust the position of the speakers according to the actual situation.

The choice of campus wooden speaker system and the main points of installation

1. Speaker selection basis: the average power of each output channel of the IBA Runsheng smart host is 50W (connected to 4-8 ohm speakers), and the voltage is 12V. The impedance is 4~8 ohms, and the speaker selection is based on the above parameters.

2. Speaker power selection: Since the output power of each channel is 25 watts, plus line loss, it is recommended that the speaker power is not less than 15 watts.

3. How to use constant-voltage speakers: Choose ceiling speakers or wooden wall-mounted speakers. Many ceiling speakers have constant-voltage input terminals and constant-impedance input terminals. We choose constant-impedance input terminals. For constant-voltage speakers without constant-impedance input terminals, remove the transformer first, and then connect to the IBA Runsheng smart host.

4. Speaker impedance and parallel connection: If 8 ohm speakers are used, two speakers can be connected in parallel for each left channel or right channel, which is very meaningful for our design.

5. Speaker installation location and sound quality: In order to ensure the stereo effect, the characteristics of people's activities in the room need to be considered when installing the speakers. For example, in the bedroom, install the speakers on both sides of the bed; in the study, install the speakers on both sides of the desk; in the dining room, consider installing the speakers on both sides of the dining table. In general, keeping the distance between the speakers at about 1.5 times the layer height will have a better stereo effect. If the room is large, consider connecting two 8 ohm speakers to the left and right channels respectively to make the sound quality more uniform and the stereo effect is better.

6. Wall-mounted speakers: some rooms do not have a ceiling, only wall-mounted speakers can be installed. The professional design of campus wooden speakers is practical and beautiful. Nanshan Hotel Campus Wooden Speaker Sales

Wiring method of constant voltage power amplifier and campus wooden speaker

Constant voltage power amplifier: As long as the input voltage of the speaker matches the output voltage of the power amplifier, and the total power of the speaker does not exceed the total power of the power amplifier, one speaker can be directly connected in parallel to the output of the power amplifier.

Smallpox speaker: For the bass, it is a speaker that accepts a relatively large current in the audio. It must be directly connected to the power amplifier in order to obtain a relatively large low-frequency current. Connect it to 4 ohms in parallel with the full-tone speaker. If you want better audio, you need to buy a crossover. Extended information: The term constant voltage output can easily cause cognitive errors. In the application of constant voltage amplifiers, it is an AC concept. The effective value of the voltage at full power output is the rated voltage of the constant voltage amplifier, which is neither the constant voltage in the DC concept. Maintaining a constant voltage and current changes with the signal, nor is the effective value of the AC voltage constant in the AC concept.
