BST UPP1480 - 480W Single-Channel Power Amplifier

BST UPP1480 - 480W Single-Channel Power Amplifier

The BST UPP1480 amplifier is the ideal solution for professional sound installations and PA systems. With a single-channel output of 480W, it delivers clear and dynamic reproduction in environments ranging from auditoriums to retail and corporate spaces. Its 19" 2U rackable design facilitates integration into standard rack cabinets, while its dual handles allow for easy transport and installation. The combination of multiple inputs and outputs (XLR, 6.35mm jack, RCA, and terminal blocks) ensures maximum versatility when connecting consoles, players, and speakers in 100V, 70V, or 4–8Ω modes.

Main features

• Output power: 480W on one channel.
• Frequency response: 30 Hz – 20 kHz.
• Total harmonic distortion (THD): < 0.5%.
• Line inputs: XLR, 6.35 mm jack, RCA and terminal blocks.
• Loop outputs (link): XLR, jack, RCA and terminal blocks in 100 V, 70 V and 4–8 Ω.
• Active cooling by low-noise fan.
• Dual power supply: 220–240 Vac (50–60 Hz) and 24 Vdc (backup).
• Multiple protection circuits: short circuit, overload, over temperature and continuous output.
• 19" rack format (2U) with two integrated handles.

Product benefits

• Installation versatility: Compatible with PA systems in 100 V, 70 V and low impedance speakers (4–8 Ω).
• Professional Reliability: Advanced protections and dual power supply for continuous operation without interruptions.
• Sound quality: Wide frequency response and low distortion for faithful reproduction of music and messages.
• Easy integration: Standard rack format and universal connections that facilitate mounting and interconnection.

Use cases

Ideal for alarm and PA systems in shopping malls, hospitals, and transit stations; sound reinforcement in auditoriums, conference rooms, and retail spaces; and power backups in facilities where service continuity is critical.

Frequently Asked Questions

• Can it operate on 24 V DC alone? Yes, it allows for emergency power at 24 V DC if the 220–240 V AC power grid fails.
• Is it possible to connect multiple speakers in parallel? Yes, in 4–8 Ω mode, as long as the total impedance is compatible and does not exceed the amplifier's power rating.
• How is the internal temperature controlled? It has a variable-speed fan that adjusts airflow based on the thermal load.
