Audibax Pro PA2250T - 19″ 2×240 W installation amplifier (Class D, Low-Z/70/100 V) with zone control

Audibax Pro PA2250T - 19″ 2×240 W installation amplifier (Class D, Low-Z/70/100 V) with zone control

The Audibax Pro PA2250T is a 2-channel Class D installation amplifier in 19″ (1U) rack format, designed for professional background music and PA systems in retail, hospitality, education and corporate environments. It offers flexible operation in both low impedance (Low-Z) and 70/100 V lines , with 2×240 W RMS at 8 Ω , Euroblock balanced inputs (2 channels) and volume control per zone (2). The high-efficiency architecture and auto-standby reduce consumption and heat in 24/7 use, while the switchable high-pass filter (70 Hz) and rear gain per channel allow for fast and consistent adjustment. It incorporates status indicators (protection, clip, input and output) and complete protections for stable and safe operation.

Main features

• Power and formats: 2x240 W RMS at 8 Ω; Low-Z / 70 V / 100 V outputs switchable per channel.
• Class D efficiency: lower heat dissipation and continuous silent operation.
• Professional connectivity: Euroblock balanced inputs (2 channels) and Euroblock screw speaker outputs .
• Zone control: 2 independent volumes (one per channel/zone) on the rear panel.
• Signal quality: THD+N < 0.01% (plug), SNR > 80 dB and crosstalk > 60 dB .
• Filtering and adjustment: switchable high-pass filter (70 Hz) and rear gain per channel (DIP).
• Smart operation: auto-standby after 1 minute without signal and automatic reactivation when audio is detected.
• Protections: short circuit, overload, temperature, clip and DC; limiter and peak detection .
• Installation chassis: 1U / 19″ ; 484 × 420 × 44 mm ; 7.3 kg ; power supply AC 100–240 V, 50–60 Hz .

Product benefits

• True versatility: a single unit for Low-Z speakers and 70/100V lines, simplifying design, purchasing and maintenance.
• Clean and fast installation: Euroblock on inputs and outputs for secure rack wiring and agile inspections.
• 24/7 Stable Sound: Class D efficiency, auto-standby and comprehensive protections for maximum reliability.
• Zone tuning without external DSP: Switchable rear gain and HPF optimize intelligibility and dynamic range.

Use cases

• Retail and hospitality: ambient music by zone with long runs at 100 V.
• Education and corporate: classrooms, auditoriums, and offices with discreet sound reinforcement and minimal maintenance.
• Sports and leisure centers: consistent coverage across large areas with simple channel control.

Frequently Asked Questions

• Does it include DSP or network control? No. The PA2250T prioritizes installation simplicity (gain and DIP). For DSP/Network, see the MA DSP series.
• Can it operate in 70/100 V and low impedance? Yes, each channel can be configured for Low-Z or 70/100 V.
• What is the difference between the data sheet and the manual regarding THD? The data sheet indicates THD+N < 0.01% at full power; the manual specifies THD < 0.1% @ 1 kHz, 100 W. Both figures are official and refer to different measurement conditions.
