Rondson AM120UB 120W Bluetooth Amplifier Preamplifier with USB SD Recorder FM Tuner and 24V Backup
Rack Mount Mixer Amplifier with Backup Power for Critical Installations
The Rondson AM120UB is a 120W mixer amplifier built for professional installations where downtime is not an option. It occupies 2U in a standard 19 inch rack and weighs 12.8 kg.
The standout feature is the 24V DC backup input. When mains power drops, the amplifier instantly switches to battery. Emergency announcements still reach every speaker. Fire alarm paging stays live. Security messages get through. This is not a nice to have. For schools, hospitals and transport hubs, it is a requirement.
Four Phantom Powered Mic Inputs
Four balanced unbalanced XLR inputs. Each input has a switch for MIC or LINE level. Each input has phantom power. Plug in four condenser microphones without external power supplies or inline adapters.
MIC 1 includes priority. Speak into it and music drops automatically. The TEL input works the same way. Phone page cuts through background music instantly.
Complete Media Source Built In
No external players needed. No extra boxes in the rack. The AM120UB includes:
| Source | Function |
|---|---|
| FM tuner | Local radio stations |
| USB port | MP3 playback plus recording |
| SD card slot | MP3 playback plus recording |
| Bluetooth | Stream from any phone tablet or laptop |
The recording function captures live audio directly to USB or SD. Record assemblies, sermons, meetings or training sessions without external recording gear.
Four Output Configurations
One amplifier does the job of four. Select your output type on the rear panel:
| Output | Best For |
|---|---|
| 25V line | Small distributed systems, shorter cable runs |
| 70V line | US standard commercial installations |
| 100V line | UK European standard commercial PA |

Complete Connection Panel

| AMP IN | Return from processor |
| LINE OUT | Feed additional slave amplifiers |

Visual Monitoring
Output level VU meter shows signal level at a glance. No squinting at tiny LEDs. No guessing if you are clipping.
Commercial Grade Protection
Fan cooling for all day operation. Thermal protection shuts down before damage occurs. Overload protection stops input spikes. Short circuit protection saves the amplifier if speaker wires touch.
