Multizone power amplifier

Designed for multizone applications.

PA 1504 is a power amplifier featuring 4 channels of 150 W each. Using switches, user can easily combine inputs and edit configuration of the installation.

Depending on switch position, the amplification system changes audio distribution in the different areas (up to 4 audio sources available for each of the 4 areas). PA 1504 can also be used as a sound reinforcement system for a concrete area (mono or stereo, for 1, 2 or 4 different outputs). It is also possible to select between stereo and bridge operating modes.

PA 1504 has individual gain controls on front panel and LEDs that indicate the state of each channel (signal, clip, protections or Bridge mode). The unit is protected from speaker short circuits, thanks to its signal auto-compression function. Output signal automatically drops down if the temperature starts becoming too high. Overvoltage protection eliminates current fluctuations and starting current peaks.
