The Details Related Solution Related Cases Related Video Download


Description:


Used in multimedia classrooms, lecture halls , training rooms and other places where sound amplification is required.


Feature:


*Supports 1-channel microphone , 1-channel stereo line input and line output .

*It has output overload, overvoltage and short circuit protection functions .

*With mute function, 100V broadcast input takes precedence over line input.

*It has 1 microphone volume adjustment, 1 line input volume adjustment, and 2 treble and bass adjustments.

*Built-in HIFI high-fidelity high-end speakers, built-in electronic crossover, high and low frequency units with independent power amplifier drive for better sound quality.

* For acoustic simulation in AFMG EASE / EASE Evac, the T-250BH shares its acoustic data with the ITC T-903B. Please use the T-903B GLL file for T-250BH designs. Both models have the same transducers and dispersion characteristics, so simulation results with the T-903B GLL are representative of T-250BH performance
