This document outlines the features and operational guidelines for the DSPPA Mixer Amplifier, a versatile audio solution designed for a wide range of public address applications. The manual emphasizes safe installation and operation, providing detailed instructions to ensure optimal performance and longevity of the device. Users are strongly advised to read the entire manual carefully before installation and use, and to retain it for future reference.
The DSPPA Mixer Amplifier is a comprehensive audio system that integrates mixing, amplification, and various playback functionalities into a single unit. It is engineered to deliver high-quality audio in diverse environments such as schools, stadiums, squares, venues, parks, parking lots, railway stations, airports, villas, and shopping malls. The device supports multiple audio inputs, including microphones, line-level sources, and digital media, offering flexible connectivity for different audio setups.
A key feature of this mixer amplifier is its multi-zone output capability, allowing for independent volume control across six distinct zones. This enables tailored audio distribution, where different areas can receive audio at varying levels or be selectively activated. The system incorporates a robust priority function, ensuring that critical announcements or emergency signals override other audio sources. The priority order is MUTE > EMC IN > SIREN > MIC1 > CHIME > Remote paging > LINE1 = MIC2/LINE2 = MIC3/LINE3 = MIC4/LINE4 = MP3 = BT = FM, with the exception that no chime output occurs during an alarm sound.
The amplifier is equipped with built-in Bluetooth, FM radio, and MP3 playback capabilities, providing a wide array of entertainment and information delivery options. It supports USB and SD card inputs for playing stored audio files, enhancing its versatility as a media player. Remote paging functionality is facilitated through two-channel RJ-45 interfaces, which offer zone control and a strong cut function, supporting up to six cascaded paging stations per channel with transmission distances of 300m-600m.
For emergency situations, the device includes a 1-channel EMC alarm signal input, allowing it to receive and broadcast alarm signals from external systems. It also features SIRNE short-circuit trigger and MUTE short-circuit trigger functions, enabling remote control or control by other equipment for alarm sound output and muting. The system is designed with a power-off memory function, ensuring that it resumes with the last displayed content upon power restoration.
The DSPPA Mixer Amplifier is designed for user-friendly operation, featuring an LCD lattice screen with backlight for clear information display. A five-segment level indicator provides visual feedback on audio output levels.
The front panel offers intuitive controls for managing various audio sources and output zones.
The rear panel provides comprehensive connectivity options.
The infrared remote control provides convenient access to key functions:
The DSPPA Mixer Amplifier is designed with durability and safety in mind, incorporating several features and guidelines for proper maintenance and longevity.
By adhering to these guidelines, users can ensure the safe, efficient, and long-lasting operation of their DSPPA Mixer Amplifier.
