LTC Audio PAA150BT - 4-Zone PA Amplifier with USB/SD/FM/Bluetooth (90W RMS)

The LTC Audio PAA150BT is a 4-zone PA mixer amplifier for flexible message and background music distribution in retail, hospitality, educational and public buildings. It features built-in USB/SD playback, an FM tuner , Bluetooth , and three line inputs , plus two microphone inputs with priority on MIC 1 for clear announcements. Low impedance (4–16 Ω) outputs and 70/100 V line outputs are suitable for both conventional loudspeakers and distributed systems. It includes a display , remote control , bass/treble controls, and is housed in a 19″ metal enclosure with front-mounted handles and is powered by a copper transformer for reliability.

Main features

• Output power: 90W RMS (max. 150W).
• Zoning: 4 zones selectable from the panel.
• Audio inputs: USB/SD player, Bluetooth , FM and 3× Line (RCA, 400 mV).
• Microphones: 2× MIC (6.35 mm jack, <15 mV) with priority on MIC 1 .
• Outputs: 4–16 Ω / 70 V / 100 V + line output (RCA).
• Controls: independent volumes (master/line/mic) and bass/treble .
• FM: 87.5–107.5 MHz in 0.1 MHz steps.
• Construction: 19″ metal chassis with front handles and copper transformer .

Technical highlights

• Frequency response: 80 Hz–12 kHz; THD < 2 % (30–20 kHz); S/N > 65 dB (A).
• Input level/impedance (Line): 400 mV. MIC: < 15 mV.
• Power supply: 220–240 V~ 50/60 Hz.
• Dimensions: 480 × 90 × 350 mm (w×h×d); Weight: 7.9 kg.

Product benefits

• Zone management: Send music or announcements only where needed, improving the experience in rooms and hallways.
• Full connectivity: play from USB/SD, mobile via Bluetooth, FM radio or external sources via line.
• Clear messages: MIC 1 priority attenuates music when speaking for always intelligible speech.
• Versatile installation: works with low impedance speakers and 70/100 V networks.
• Professional durability: metal chassis, front handles and copper transformer for continuous work.

Use cases

• Retail and hospitality: ambient music by zone and service announcements.
