Key Features
- High Power Output: Delivers a maximum power of 300W and a continuous 250W RMS at 10% THD, ensuring your announcements and audio are heard clearly.
- Versatile Inputs: Features 6 Microphone inputs and 2 Auxiliary inputs to accommodate multiple audio sources simultaneously.
- Advanced Output Options: Includes a Preamplifier and Line Output for connecting to a booster amplifier (like the BR-250M) or for recording programs.
- Booster Amp Capability: A dedicated Line Input allows the connection of external mixers, or permits the SSA-250M to be used as a booster power amplifier.
- Instant DC Power Fallback: Ensures uninterrupted performance by instantly transferring to a 24V DC power source (such as two 12V car batteries) if AC mains power fails.
- Safety & Protection: Equipped with a resettable circuit breaker that actively protects the unit against electrical overloads and short circuits.
- Speaker Selector Switch: Comes with a Box Speaker / Driver Unit selector switch. Bass boost is automatically defeated when switched to the Driver Unit position for safer operation.
