The Model 7.250 power amplifier features include:
- Single-ended RCA or XLR balanced inputs
- 250 Watts/8 ohms; 400 Watts/4 ohms
- Remote trigger (works with +3.3 to +24 Volts DC)
- Protection against short circuits, device failures, mis-wiring, and internal faults.
- DC offset protection
- Matched output transistors
- High power supply voltage for extra headroom at the outputs
- Stable with mismatched, reactive or unusual loads
- Soft start circuit prevents “Brown outs” when amplifier is turned on
In addition, the Model 7.250 includes high quality RCA (gold plated) and XLR input connectors. The Model 7.250 also includes high-quality, heavy duty speaker output connectors. A trigger input connector allows the Model 7.250 to be powered on and off automatically. |
