PA7002

DSPPA PA7002 - installation power amplifier 1500W for 100V/70V lines and loads of 4-16Ω, rack mountable in a 19" cabinet

The DSPPA PA7002 is an installation power amplifier of 1500W for public address systems and professional audio installations. It works with speakers in 100V and 70V lines as well as low-impedance speakers of 4-16Ω. The operating mode is selected by connecting the "+" wire of the speaker line to the appropriate terminal of 4-16Ω, 70V, or 100V, while the "-" wire is always connected to the common terminal COM. This allows one model to support both extensive zone installations in buildings and systems with low-impedance speakers. The signal is fed into the XLR or 6.3mm jack input. The linking XLR and 6.3mm jack outputs allow for signal transmission and cascading multiple amplifiers. The amplifier is designed for long-term, continuous operation in industrial applications and professional installations. The fan cooling with automatic speed control adjusts performance to the load. Advanced protections safeguard the device and connected speakers against short circuits, overheating, overload, DC voltage, and excessively high input signals. Five LED indicators on the front panel signal the operating status, and the gain control allows for quick level adjustment. The housing with mounting brackets for a 19" rack facilitates installation in the sound system central.
