2x1000w/8¦Ø high power amplifier, professional audio sound equipment, PRO audio sound equipment, pa amplifier system, stereo amplifier, professional power amplifier.
1. High fidelity, can work with any loudspeaker that needs big power easily.
2. Perfect circuit design and high efficient power transistors with fast recovery power supply guarantees the machine to work freely under big power.
3. Complete protection against currents in-rush, DC, shorted, open, close and overheating.

4. Front-to-rear forced airflow path excited by two speed fan allows the machine to work normally in bad conditions.
5. Balance xlr and 1/4trs loop-through input connectors
6. Speakon cord mating twist & lock connector
7. High current binding post output connect
8. Two mono modes ( bridge-mono and parallel-mono) for driving a wide range of load.
