iAC 4X125 DSP professional installation amplifier provides both 100V constant voltage and low impedance transformerless outputs. It has Full 4x4 Matrix, enabling complete routing flexibility. Internal DSP processor provides each channel with individual 6-point parametric EQ, high-pass and low-pass filters, limiter, delay and input gate. iAC 4X125 DSP also has full RS232 control and allows for remote control and automation of the amplifier using a standard serial connection.

Amplifier‘s power supply has Power Factor Correction (PFC) circuit that optimizes the power usage of the amplifier, improving efficiency and reducing the strain on the electrical system. This also helps in complying with energy standards by reducing harmonic distortion and improving the power factor. Further power efficiency is achieved with the auto standby feature that automatically powers down the amplifier when it detects no signal input. Once a signal is detected, the amplifier powers back up without manual intervention.
