BỘ KHUẾCH ĐẠI CÔNG SUẤT NAC-3240

Functions:

1.1U switch appearance design.

Simple and user-friendly engineering design, the front panel displays status signals, and the switch and volume knob are rear-mounted to reduce unprofessional operations and maintenance failures.
Built-in high-efficiency digital power amplifier, constant voltage 100V output, efficiency as high as over 90%.
With front signal input function (1 channel microphone input, 2 channels auxiliary line input, 1 channel network audio), each audio channel has independent volume adjustment. At the same time, the line input supports balanced input, which effectively reduces the access noise during system connection and improves the signal-to-noise ratio of the system.
It has 1 alarm input and 1 alarm output to link peripheral equipment.
Internationally accepted wide-voltage power supply design, with strong power supply voltage adaptability.
Built-in complete protection circuit, supports multiple protection functions such as overload and overheating protection, and supports power supply and line lightning protection and surge protection.
