Overview of Ahuja SSA-250M 250W PA Mixer Amplifier

The Ahuja SSA-250M is a 250W PA mixer amplifier designed for medium to large public address systems that require dependable performance and flexible connectivity. Featuring 6 microphone inputs, 2 auxiliary inputs and 1 line input, it allows multiple audio sources to be connected simultaneously. The amplifier also includes preamp and line outputs for connecting a booster amplifier or recording equipment. Supporting 4Ω, 8Ω, 70V and 100V speaker systems, along with automatic 24V DC battery backup, the SSA-250M is well suited for schools, places of worship, auditoriums, factories and commercial PA installations.

Steady Power for Public Address Setups

The SSA-250M delivers 250 watts RMS output at 10% THD, with a maximum output of 300 watts. This power output is suitable for medium to large public address setups where sound needs to reach across bigger rooms or open areas clearly.

Multiple Inputs for Flexible Audio Management

This amplifier offers 6 mic inputs, 2 aux inputs, and 1 line input, allowing several microphones and audio sources to be connected together. This makes it convenient for setups that require managing announcements, background audio, and external devices at the same time.

Connectivity and Speaker Compatibility

A preamp and line output allow the SSA-250M to be linked with a booster amplifier or a recording device, while the line input lets it take signal from an external mixer or work as a booster power amplifier. On the speaker side, it supports 4Ω and 8Ω loads along with 70V and 100V line output, making it usable in both compact rooms and larger distributed speaker installations. A box speaker/driver unit selector switch also lets you adjust settings depending on the type of speaker connected.

Built-in Protection and Backup Power

Safety is built into the design with a resettable circuit breaker that guards against overload and short circuits. If the AC power supply fails, the amplifier switches instantly to DC power using a car battery, so audio output continues without interruption. Bass boost is automatically defeated at the driver unit position, which helps protect driver units during use.
