The UPM-300 H/V is a high-quality 3-channel flush-mounted mixer, designed specifically for professional applications. It is perfectly suited for conference rooms, presentation areas, or public installations where reliable, space-saving audio control is required. Thanks to its versatile input configuration, the UPM-300 supports a microphone via XLR (with 18V phantom power), a line-level source via RCA connectors, and an additional source via 3.5 mm stereo jack (e.g., smartphone or iPod®).

Each input channel is equipped with its own level control and signal indicator LED for easy monitoring. The symmetrical output ensures noise-free signal transmission, with the output level switchable between 0 dB and +6 dB. The unit is installed in an optional 3-gang flush-mount wall box or surface-mount housing, making it ideal for tight spaces. When combined with the optional PGA-300 Plexiglas cover, the UPM-300 is even ball impact-resistant. An optional 2-button keypad (UPM-002 S) allows for additional user-configurable control functions.
