What are the differences and advantages of active speakers and passive speakers?
When you buy speakers, will you wander between active speakers and passive speakers? Passive speakers are very popular, but active speakers also have many fans. So, how to choose active speakers and passive speakers? What is the difference between them? What are their advantages?
Active speaker means that the speaker has built-in splitting and amplifying circuit, and only need to connect the power supply and input music signal to make sound. Many monitor speakers in the studio and professional speakers for engineering are active speakers. However, don't think that the synonym for active speaker is expensive and professional, because everyone's common and commonly used computer speakers, Bluetooth speakers, etc. are actually active speakers.
1. No post grade power amplifier, simple system.
One of the significant advantages of active speakers is that there is no need to connect to the rear driver. You can play songs as long as you input audio. It is very suitable for friends who want a simpler sound system. Only a player and a speaker can form a complete system.
2. Save space.
Because the active speaker does not need to be connected to the amplifier, it can save a lot of space for equipment. Very suitable for mobile stage, touring stage, etc. Effortless transportation.
3. Complete support and sound quality are guaranteed.
Since the speaker itself has a complete driving circuit and is equipped with decoding and demultiplexing, plus the input through the digital interface, the sound floor of the active speaker will be more stable, unlike passive speakers that are more affected by wires and amplifiers.
1. The speaker needs to adjust the volume independently
In the design of some active speakers, the output of the left and right channel speakers needs to be adjusted independently, so it will be a little more troublesome to do the volume adjustment. You need to fine-tune the left and right speakers.
2. Need to connect power cable and signal cable
Although the active speaker does not need to be connected to the power amplifier, in addition to the signal line, it is necessary to connect another power cord to each speaker. If the speaker is far away, the connection will be more troublesome.
Passive speakers, contrary to active speakers, do not have a built-in amplifier circuit, and need to rely on the output of the post grade power amplifier or the combined machine to drive the sound.
1. More flexibility in tuning
Due to the need to connect the amplifier drive, the sound bottom of the passive speaker will be greatly affected by the connected equipment and the wire. Sometimes the same set of speakers appears, and it feels completely different to hear it from someone else than from yourself. However, there is more flexibility in tuning in disguise. You can use the characteristics of the signal cable and the amplifier to supplement or improve the performance of the speaker.
2. Just connect the speaker cable
Although it is necessary to connect the amplifier, the passive speaker does not need to connect an additional power cord. It only needs to be connected to the amplifier through the signal line, and the latter can be driven directly to make sound.
Need to promote the post grade power amplifier.
Because passive speakers are too diverse, and the specifications, design and materials are different. If you want to talk about a common shortcoming, it is that you need to connect the amplifier drive, and you need additional equipment and space.
The above is the sharing of some knowledge about active speakers and passive speakers. Maybe it can help you when you struggle with which speaker to buy.
