Emb 3-Channel Mixing Amplifier 300 Watts 70V 100V Stereo USB Bluetooth 4-16ohm

The EMB ECP3150 is a rack-mountable mixing amplifier designed to combine microphone, line-level, and digital media sources in one compact PA audio component. It is intended for systems using compatible passive speakers with 4–16-ohm or 100V speaker connections. With a listed maximum power rating of 300 watts, it provides a centralized solution for distributed music and voice playback.

This amplifier suits small commercial, public-address, presentation, and background-music installations where several common audio sources need to share one speaker system. A dedicated microphone input supports announcements or live voice, while two line-level inputs accommodate external playback equipment. Bluetooth and onboard media playback reduce the need for a separate wireless receiver or media player.

The ECP3150 is specified with an 80 Hz–18 kHz frequency response for general music and speech reinforcement. Its bass control is rated at 10 dB at 100 Hz, allowing adjustment of low-frequency presence to better suit the speakers and room. The microphone input is specified at 35 mV and 600 ohms.

Built-in Bluetooth supports wireless audio streaming from a compatible device. The integrated MP3 player is listed as supporting USB storage, flash disks, and SD cards for direct playback. This makes the amplifier practical for installations that need simple local music playback alongside connected source equipment.

For system expansion, the ECP3150 can serve as the amplification and source-mixing point between audio inputs and compatible passive PA speakers or monitors. Its 100V and 4–16-ohm output compatibility provides options for matching the amplifier to the intended speaker wiring approach. It operates from an AC 110V–250V supply.

Design & Installation

The ECP3150 uses a rack-mountable amplifier form factor suited to organized audio equipment installations. Published product information identifies its rack-mount capability, built-in Bluetooth, and onboard media-player functions. Specific chassis materials, rack size, dimensions, and weight are not published in the available product information.

Install the amplifier with compatible passive speakers wired for the selected 4–16-ohm or 100V output arrangement, and connect source devices to the microphone or line-level inputs as needed. Use Bluetooth, USB storage, a flash disk, or an SD card when direct media playback is preferred. Confirm speaker load, wiring method, source connections, and local electrical requirements before installation.
