Audibax Memphis 30 USB - 30W Bluetooth Amplifier with USB/TF Player, FM Radio and Remote Control

The Audibax Memphis 30 USB is a compact amplifier-mixer designed for public address and sound reinforcement systems in commercial and educational spaces. It offers up to 2 × 15 W output into 4–8 Ω, Bluetooth connectivity (2.4 GHz) for wireless playback, and an integrated MP3 player with USB and TF card ports. It features two microphone inputs, one line input, and a pair of RCA input/output connectors, as well as priority and mute functions to emphasize voice announcements. Its lightweight design (150 × 52 × 190 mm, 1 kg) makes it easy to install in counters, control booths, or shallow racks.

It is designed to operate both on mains power (110–230 V~ 50/60 Hz) and a DC power supply (12–16 V), enabling mobile use or power redundancy. For greater reliability in fixed installations, it features a 2 A fuse and protection systems against short circuits, overheating, and overload. Audio quality is supported by a wide frequency response (microphone 100 Hz–20 kHz; line 30 Hz–20 kHz), total harmonic distortion of less than 1% (1 kHz), and a signal-to-noise ratio of >70 dB for microphone and >80 dB for line.

Main features

Frequently Asked Questions

• Can I connect 4 Ω or 8 Ω speakers? Yes, the amplifier supports 4–8 Ω loads. It is not a 70/100 V line amplifier.
• Does it have tone controls (bass/treble)? No, this model does not incorporate tone equalization.
• Does it work with 12V? Yes, it supports 12–16V DC power as well as 110–230V~.
• Is it compatible with microphones? Yes, it has 2 dedicated microphone inputs with priority.
• Does it include a remote control? Yes, it includes a remote control with a CR2032 battery.

Installation and recommendations

• Respect the total impedance of the speakers (4–8 Ω) and the appropriate wiring; in series the impedance adds up and in parallel it divides.
• Place the amplifier in a well-ventilated and unobstructed location to avoid overheating.
• Use stable power supplies and the specified 2A fuse protection.
