The Ahuja WSX-551T is engineered for direct integration into commercial 100V constant-voltage public address (PA) and background music (BGM) distribution networks. Operating on high-impedance 100V distributed speaker lines, this unit allows system integrators to parallel-wire multiple speaker units across expansive multi-zone layouts without signal degradation over long cable distances.
100V Line Power Tap Selection and Impedance Matching
The speaker incorporates an internal line-matching transformer with selectable power taps to optimize acoustic output levels for specific room dimensions and background noise profiles. Tapping selection is executed via push-fit female receptacle terminals, ensuring dependable contact without complex wiring modifications.
| Operating Voltage | Power Tap Rating | Matching Impedance | Primary Application |
|---|---|---|---|
| 100V Line | 5.0W (Max RMS) | 2,000 Ω (2 kΩ) | High-ambient noise zones, larger commercial showrooms, dining areas |
| 100V Line | 2.5W | 4,000 Ω (4 kΩ) | Standard office cabins, school classrooms, bank customer service areas |
| 100V Line | 1.25W | 8,000 Ω (8 kΩ) | Low-noise environments, hospital corridors, hotel guest hallways |
PA Amplifier Capacity and Load Budgeting
When engineering a public address system utilizing the WSX-551T, the total wattage load on the amplifier is calculated by summing the configured power tap values across all connected units. The speaker features an input power rating of 5W RMS (with a 7.5W Max threshold), presenting load impedances of 2 kΩ, 4 kΩ, or 8 kΩ corresponding to the 5W, 2.5W, and 1.25W settings.
Integrators must ensure that the total wattage of all parallel-connected WSX-551T speakers does not exceed the continuous 100V output capacity of the central PA amplifier, maintaining standard engineering headroom to prevent clipping and line distortion.
Acoustic Integration and Facility Matching
Equipped with a 12.7 cm (5-inch) full-range speaker driver delivering a sound pressure level (SPL) of 92 dB at 1 kHz (1W/1m), the WSX-551T delivers clean speech intelligibility and background audio reproduction across a broad frequency spectrum of 80 Hz to 15,000 Hz. It is matched for installation across commercial and institutional architectures, including:
- Corporate offices, BPO facilities, and administrative complexes
- Educational institutions and school lecture halls
- Healthcare facilities, clinic waiting areas, and hospital corridors
- Retail showrooms, banking halls, and restaurant dining spaces
- Hospitality environments including hotel lobbies and service areas
Physical and Mechanical Mounting Compatibility
The WSX-551T is housed in a compact white ABS plastic cabinet measuring 179 mm (Width) x 195 mm (Height) x 101 mm (Depth) and weighing 0.80 kg. For installation versatility, the rear panel features an integrated keyhole slot for fast wall hanging, while dedicated front fascia screw mounting provisions allow secure, vandal-resistant fastening to solid masonry, drywall, or partitioned surfaces.
