Overview of Ahuja SSA-250DP 250 Watts Mixer Amplifier

The Ahuja SSA-250DP is a 250W PA mixer amplifier designed for medium to large public address systems. It features 6 microphone inputs, 2 auxiliary inputs and a built-in MP3 player with USB and SD/MMC card support. Compatible with 4Ω, 8Ω, 70V and 100V speaker systems, it is suitable for schools, places of worship, auditoriums, factories and commercial PA installations. Automatic DC battery backup helps keep the system running during power failures.

High-Power Performance for Large PA Systems

Delivering 250W RMS output (300W Max.), the SSA-250DP provides powerful, clear sound for voice announcements and background music. Its wide frequency response and adjustable bass and treble controls help maintain balanced audio in different environments.

Flexible Inputs and Speaker Compatibility

The SSA-250DP offers 6 mic inputs, 2 aux inputs, and 1 line input, so several microphones and audio sources can be connected together. A preamp and line output allow the amplifier to be linked with a booster amplifier or a recording device. On the speaker side, it supports 4Ω and 8Ω loads along with 70V and 100V line output, which makes 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 is not interrupted. Bass boost is automatically defeated at the driver unit position, which helps protect driver units during use.
