More Information

Features/General Description of Product:

  • Designed for use in a wide variety of PA applications.
  • SSA-250®M is a 250 Watts Mixer Amplifier with Four Unbalanced Independent Mic inputs and Two Unbalanced Mic Inputs alternate to two Auxiliary inputs.
  • SSA-250®M has a Preamp output for recording the program, a Line output for connecting to a Booster Amplifier and a Line input for connecting to an external PA Audio Mixer.
  • Box Speaker/ Driver Unit selector switch has been provided for protecting the Driver Unit's diaphragm from unwanted low frequencies. Since Box speakers can reproduce the full spectrum of audio frequencies but Driver Units cannot reproduce very low frequencies, the switch should be positioned to the Driver Unit side when Driver Units, Horns and Column speakers are connected.
  • Circuit Protector Device has been provided which safeguards the amplifier against overload and short circuit.
  • Provision for automatic changeover from AC to Battery Operation ensuring continuity of program has been provided.
  • Protection provided against the reverse polarity of Battery connections.
  • Ease of operation, combined with service accessibility has been optimized in the design.
