The VP-4DRV is similar purpose of the VP8-DRV,compact size very economic with full-featured best buy. 4 CH input 170W dual purpose designed for 70V/100V output and 8 ohm full range output with high-fidelity specification. The 90 W high voltage outputs effectively match the impendance of a wall mount, out door indoor loud speaker and paging horn speakers,Another 8 ohm 75 W quater inch phone jack outputs connect to STK 2 way SP112 full range speaker or other equivalent products.
- 4 CH 12 input configurations
- Barrier strip 70V/100V output terminals.
- The Mic preamps extra 10dBu input handling capacity.
- Ultra realistic sound with 20kHz response dual variable DRV digital effects
- Convection cooling with large size heat sinks
- FET control quiet power on/off muting circuit.
- Lowest in-rush trodial transformers.
