The IMG Stageline STA-850D is a professional-grade 8-channel digital amplifier designed for multi-zone audio applications. Paired with the LS-280/SW 8-way line splitter, this combination offers versatile audio distribution suitable for venues such as conference centres, auditoriums, and houses of worship. The STA-850D delivers efficient amplification with silent operation, while the LS-280/SW ensures precise signal routing to multiple destinations.
Both units feature robust metal chassis construction, ensuring durability for rack-mounted installations. The STA-850D's fanless cooling design promotes silent operation, making it ideal for environments where noise levels must be minimised. The LS-280/SW's compact 1U rack-mountable form factor allows for efficient use of space in professional audio setups.

The STA-850D and LS-280/SW system delivers consistent, high-fidelity audio across multiple zones with virtually silent operation. Its flexible routing options and comprehensive controls make it ideal for both technical audio engineers and facility managers. Whether integrated into an installed sound system or used in live scenarios, this setup offers precision control, reliability, and easy configuration.
Q: Can the STA-850D be used in quiet environments like recording studios?
A: Yes, its fanless design ensures silent operation, making it suitable for acoustically sensitive environments.
Q: Is the amplifier compatible with 100V line systems?
A: No, the STA-850D is designed for low impedance speaker loads (4 Ω or 8 Ω), not for 100V line systems.
Q: Can I bridge channels for more power?
A: Yes, it supports bridging to 4 x 100 W at 8 Ω, ideal for more demanding speaker setups.
Q: What makes the LS-280/SW useful for installations?
A: Its dual-mode signal routing and individual gain controls make it extremely versatile for zone-based audio distribution.
Q: Are all connections balanced?
A: The XLR connections are balanced, while RCA inputs on the STA-850D provide unbalanced options for greater compatibility.
