Electro-Voice Tour Grade amplifiers, such as the TG7, have a microprocessor controlled operation management system that provides useful features such as compound thermal management (preventing amps from switching off in excessive thermal environment), automatic mains voltage detection and a circuit breaker control that allows the TG-7 to operate on a 30A (120V) or 16A (230V) circuit breaker with normal music signal.
Tour Grade amplifiers use a grounded bridge 3-step class-H topology to ensure the highest acoustic performance and reliability. The TG Series also offers the power and transient response to drive subwoofers along with the low distortion for critical HF signals. The high capacity switchmode power supply provides the headroom needed to ensure high dynamic outputs and reliable operation on extreme low loads.
The TG7 features:
- High-power performance for top-level tours
- Rugged, lightweight package
- 3500 W per channel (2 Ω)
- Grounded Bridge Class-H design
- Switch-mode power supply
- Microprocessor-controlled
- Front LCD panel for operation-mode setup and monitoring
- Slot for optional RCM-26 IRIS-Net-compatible DSP and control module
- 11-level protection package
