Lionbeam lb-4z100 Stereo Class-d Amplifier 1-source 4-zone

Product Description

The LIONBEAM lb-4z100 is a Class-D stereo amplifier designed for distributed audio installations requiring a single source fed to up to four independent zones. It delivers 15 watts RMS per channel to speaker loads and 105 milliwatts RMS per channel to headphone outputs, making it suitable for both background music distribution and localized listening points. The unit runs on 12 volts DC at up to 9 amps and is housed in a black metal enclosure. It includes an onboard speaker protection circuit to safeguard connected loads during startup and fault conditions. Licensed audio installers and low-voltage technicians are the typical trade installing this type of equipment.

The lb-4z100 is well suited to light commercial and residential multi-zone audio applications where a single audio source must be distributed across multiple areas simultaneously. Typical install scenarios include restaurants, retail spaces, offices, and residential whole-home audio systems where zone-level volume control is required. The 4-zone configuration allows independent speaker runs without the need for an external zone controller when source switching is not required.

Key Features

• Class-D amplifier topology for efficient low-heat operation at 12 volts DC
• 15W RMS per channel speaker output across 4 zones
• 105 mW RMS per channel headphone output per zone
• Minimum speaker load resistance of 4 ohms per channel
• Minimum headphone load resistance of 16 ohms
• Onboard speaker protection circuit prevents output damage at power-on and during fault events
• Black metal housing for rack or surface mounting in professional installs

Compatibility

Designed as an OEM-style distributed audio amplifier for 1-source, 4-zone stereo speaker systems using 4-ohm or higher impedance speaker loads.

Installation Notes

Installation should be performed by a qualified low-voltage technician or licensed audio systems installer. Disconnect the 12-volt DC power supply before making any speaker or input wiring connections. Verify that speaker loads meet the 4-ohm minimum impedance requirement before powering the unit to avoid triggering the protection circuit. Local codes governing low-voltage wiring, such as NEC Article 725, may apply depending on jurisdiction.
