Release time：2024-05-21 16:01viewed：times

1. Product Introduction
This equipment uses the new ZC30 loader horn system as the basis, fully demonstrating the composition structure and working process of the horn system.
It is suitable for the teaching needs of schools on speaker system theory and m*ntenance tr*ning.
2. Functional features
1. Real and operational speaker system, fully demonstrating the composition and structure of the speaker system.
Manipulate the switch to truly demonstrate the working process of the speaker system.
2. The panel of the teaching board is made of high-grade aluminum-plastic panels that are impact-resistant, pollution-resistant, fire-proof, and moisture-proof, and the surface is sprayed with primer using a special process; school students can visually compare the circuit diagram and the actual object to understand and analyze the working principle of the system.
3. There are detection terminals installed on the panel of the teaching pendant, which can directly detect the electrical signals of each circuit component of the system on the panel, such as resistance, voltage, current, frequency signals, etc.
4. The panel part of the teaching board adopts a 1.5mm cold plate stamping structure, which has a beautiful appearance; the chassis part is welded with a steel structure, and the surface is treated with spraying technology. It is equipped with a self-locking caster device. The base of the teaching board is equipped with a tabletop of about 40cm , convenient for placing materials, light testing instruments, etc.
5. The teaching board uses ordinary 220V AC power supply, which is transformed into 12V DC power supply through internal circuit transformation and rectification. No battery is needed, which reduces the trouble of charging. The 12V DC power supply has anti-short circuit function.
