Which is better, the reward amplifier or the love class amplifier? Don t go back if you advertise! T

I love to make loudspeakers for a longer time and have more experience.

The product technology of the reward is more advanced, and the details are better.

The best-selling model of Aijiao is 2100 or 1505 (actually the same product), and the best-selling model is C902, digital power amplifier, which can be used for 40 hours on a single charge (measured results).

I hope these two companies will get better and better.

The boss of the amplifier is a professor at Zhejiang Wanli Business School, a senior engineer of mechanics, and the amplifier is ahead of Aijiao in terms of R&D strength and market development. The first two-year warranty is the first to be launched by the factory for the series of products, the quality is excellent, the after-sales service is guaranteed, and the choice of the product is your lifelong choice!

1. Classification of teaching loudspeakers.

Teaching amplifiers are mainly used for teachers to teach, and are currently divided into two categories, one of which is waist-mounted teaching amplifiers and the other is wireless teaching amplifiers.

Second, the power of the teaching amplifier.

1. The power of the waist-mounted amplifier is about 8W, the frequency range is within 100 meters, and the timbre requirements are high 2. The power of the wireless amplifier is 35W to 100W, and the transmission distance is long, which is emitted by high-frequency radio waves, and the receiver receives and demodulates and amplified the speaker to work. Both of these are used primarily for the transmission of linguistic information.

Third, the role of the teaching loudspeaker The teacher's voice must be damaged in teaching, there will be discomfort, in order not to affect our students' listening to the class, the loudspeaker will be used to improve the quality of teaching can also effectively protect the voice, on the one hand, it is easy to manage, on the other hand, to help students practice listening. Four. Precautions for the use of teaching amplifiers:

1.When using the amplifier, the microphone should be avoided facing the speaker, and the volume adjustment should be appropriate and clear, so as to avoid distortion and feedback howling.

2.Do not pull or drag the microphone cable during use, otherwise it is easy to have poor contact between the wires.
