The efficient Bogen SPT30A 30W Paging Horn is designed for one-way or two-way sound and communication systems with a built-in, variable impedance selector switch for matching the speaker power requirements to a 25V or 70V constant-voltage line. It operates on 30 Watts, 25/70 volt or 8-ohm operation with a rotary tap impedance selector.

Features:

• Maximum speaker power capacities of 7.5W, 15W, & 30W
• Rotary switch-selected power taps on transformer models
• Consistent voltage (70V/25V) and 8-Ohms versions
• High intelligibility and efficiency; ideal for both one-way and talk back applications
• Weatherproof, all-metal construction
• 15 watts; 25/70 volt (SPT15A) or 8-ohm (SP158A) operation
• Tap settings for 70V: 15, 7.5, 3.8, 1.8, 0.9 watts; for 25V: 15, 7.5, 1.8, 0.94, 0.46 watts
• Rotary tap impedance selector on SPT15A
• Tilt and swivel base for easy positioning
