The JDM power amplifier PA-424DP

Provides quick switching from the AC voltage ~ 220V to DC ±24V. A priority relay contact of the output connector allows to implement an alert when a 3-wire or 4-wire configuration, requiring a supply voltage of ±24V. Input level 0 DB (0,775 V) 66 ohms balanced (2 program and 2 priority inputs). Option module of failure detection (FD-200) allows you to detect speaker line fault or amplifier and using a relay contact allows you to automatically replace the faulty amplifier when using the FS-3381. Protection from overcurrent. Overload protection on the input. Protection from short circuit on output. The presence of output ±24 V to external devices (max. current 500mA). Remote control switching of the amplifier from standby mode. Removable screw connectors for ease of power up the amp. When triggered, the priority control input input level program input (PGM) decays. The presence of priority control input and a priority input. 400Hz low-pass filter to equalize the sound quality.
