The remote control The 250MR achieves typically 255 W per channel into 8 ohms and 400 W into 4 ohms. Its circuitry acts on IHF tone burst performance is also impressive: typically 300 W into 8 ohms, 550 W into commands received 4 ohms and 1000 (!) W into 2 ohms.

The measure of how well it does this is called the connected to pin 1 COLD ‘common-mode rejection ratio’. In the 250MR this is more than 40 dB, or one hundred times, GROUND and this is permanently fixed as it is set by precision resistors rather than by attempting to balance variable semiconductor properties.
