[. . . ] TG5 Ultra-High Performance Two-Channel Power Amplifier Key Features: · · · · · · · · Up to 2 x 1900W into 2 Ohms Grounded Bridge Class-H Design Microprocessor Controlled Front LCD-Panel for Operation Mode Set-Up and Monitoring Slot for Optional IRIS-NetTM Compatible Control Module Complete Protection Package Only 14. 2 kg (31. 4 lbs) Designed and Manufactured in Germany Technical Specifications: Load Impedance 8 Ohm 4 Ohm Max. [. . . ] The TG-5 uses 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 and along with the low distortion for critical HF signals. The high capacity switch-mode power supply provides the headroom needed to ensure high dynamic outputs and reliable operation on extreme low loads. Optional IRIS-NetTM (Intelligent Remote & Integrated Supervision-NetworkTM ) Modules available for the TG-5 amplifiers enable state-of-the-art DSP, remote control, networking and unique system supervision ­ down to an individual loudspeaker component. IRIS-NetTM software is an expandable, open architecture application that operates under WindowsTM and supports Ethernet, CobraNetTM, CANBus, USB, and RS-232 interfaces. Several modules are available including the: RCM-26 (DSP, AES/EBU input, GPIO, CANBus), RCM-28 (DSP, GPIO, COBRA-NetTM) and the RCM-20 (no DSP, CAN-Bus) The modules enable different levels of control and monitoring of the amplifier.
