Bridged Mode

The F1200 / F800 provides a rear-panel switch that allows it to be used in either a Stereo or Bridged mode. When this switch is placed in the “STEREO” (right) position, the F1200 / F800 functions as a true stereo amplifier, where both of the two independent amplifier channels (Channel 1 and Channel 2) can receive dif- ferent input signals and produce independent output signals. However, when the switch is placed in the “BRIDGED” (left) position, the Channel 1 inputs signal is routed to both power amplifiers bridged together, producing a single output sig- nal with a true 1200 watt output into a single 8 ohm channel (in the case of the F1200) or a true 800 watt output into a single 8 ohm channel (in the case of the F800).

WARNING: Bridged mode is to be used only when the F1200 / F800 is con- nected to an 8 ohm speaker load. Use of Bridged mode with speaker loads of 4 ohms or less can result in severe damage to the unit due to excessive heat and current limiting and will void your warranty!

The illustration on the right shows how this works. In Bridged mode, the polarity (phase) of the Channel 2 output signal is reversed relative to that of the Channel 1 output signal. Both channels then process the same input signal, with the speaker load connected so that power is derived from both channels. The effec- tive voltage swing seen by the load is thus doubled, so that the power output is doubled.

When using the F1200 / F800 in Bridged mode, be sure to connect your loud- speaker as shown in the illustrations on page 10 and 11 (and as silkscreened on the rear panel), with the red (+) terminal of the Channel 1 output connected to the negative input of the speaker and the red (+) terminal of the Channel 2 out- put connected to the positive input of the speaker. Do not use the black ground (-) output terminal of either channel (the speaker load must “float” away from the amplifier chassis).
