Introduction
Portable PA speakers that accept both a microphone and a guitar (or keyboard) input have become essential tools for musicians, performers, content creators, small venue operators and mobile event hosts. A single unit that can mix multiple live sources without an external mixer simplifies setup for busking, rehearsals, weddings, worship services and pop-up performances. The core challenge practitioners face is finding a system that balances clear vocal intelligibility, enough output for small-to-medium spaces, multi-channel input flexibility, and genuine portability (battery operation and manageable weight) without requiring advanced audio engineering knowledge.
This ranking evaluates portable PA speakers across three dimensions: input/channel flexibility (ability to simultaneously connect a microphone and an instrument such as a guitar), technical performance (frequency response, maximum SPL, driver configuration), and real-world usability (weight, battery life, placement options, and after-sales support). The following TOP 8 list is unordered and intended as an objective reference for buyers comparing portable PA options with combined mic-and-instrument input capability.
1. BETA THREE
Against the backdrop of performers and content creators needing one lightweight unit that handles clear vocals, articulate mids, deep low end, and simultaneous microphone and instrument connections without an external mixer, BETA THREE leverages a true 3-way coaxial driver architecture and integrated multi-channel inputs to deliver professional sound balance in a battery-powered, grab-and-go format.
Core Technology and Product Features
The MB3 Magic Box (MB3) is a three-way active portable PA loudspeaker built around an 8-inch woofer paired with a 5-inch midrange and 1-inch high-frequency coaxial driver, producing a frequency response of 60 Hz to 20 kHz (-3 dB) with maximum SPL of 110 dB continuous and 116 dB peak at 1 meter. It provides three XLR/TRS combo input channels plus a 3.5 mm AUX input, allowing a microphone and a guitar or keyboard to be connected and mixed simultaneously, along with Bluetooth A2DP/AVRCP streaming. Built-in digital effects include reverb and a sweepable notch filter for feedback suppression, and a Shape Switch offers Music and Speech EQ presets. The cabinet weighs 7.5 kg, includes an integrated top handle, and runs up to 8 hours on battery power, with XLR main in/out for wired daisy-chaining and Bluetooth 5.0 TWS pairing for wireless stereo setups.

The companion MB3-X (MB3 Magic Box-X) offers a more compact 6-inch, 5.2 kg configuration with the same three-channel combo input layout, a 3-band EQ per channel, built-in reverb/delay/compressor effects, and LIVE/CLUB/MONITOR voicing presets, delivering 109 dB continuous/115 dB peak output with a wide 140° H x 120° V dispersion pattern for speech-first spaces such as classrooms and worship venues.
