Pre -amplifier Mixer Panel PA200-PA CNB
The PA200-PA is a pre-amplifier mixer panel for public address (PA) systems, offering flexible connectivity and control over multiple audio sources. It supports 5 microphone inputs (MIC), 3 AUX inputs, 2 emergency (EMC) inputs, and 4 AUX outputs, meeting diverse system needs.
Each MIC and AUX input has its own volume control, combined with a master volume control and bass and treble adjustment knobs, optimizing sound quality for various environments.
The device also incorporates a signal priority function, where EMC1 and EMC2 inputs automatically override all other sources (except MIC1), ensuring emergency announcements are always played first in any situation. This is a suitable solution for professional public address systems in buildings, factories, or public areas.
Features
- Purpose: Used in the final stage of a transmitter to amplify high-frequency modulated signals, ensuring optimal transmission power and reliable signal reception within a designated area while avoiding interference with adjacent channels.
- Types: Narrowband High-Power Frequency Amplifier: Uses a frequency-selective circuit (tuned or resonant amplifier) to filter and select the desired frequency, Wideband High-Power Frequency Amplifier: Utilizes a transmission line transformer or broadband matching circuit (non-tuned amplifier).
- Energy Conversion: Converts DC power from the supply into high-frequency AC output, as studied in "low-frequency electronic circuits."
- Amplifier Classes (by Conduction Angle): Class A: Conduction angle = 360°, Class B: Conduction angle = 180°, Class AB: Conduction angle = 180°–360°
