1. Bridged and Parallel Modes The S700 S1000 provides a rear panel switch that allows it to be used in either a Bridged or Parallel mode When this switch is placed in the STEREO o e center position the S700 S1000 functions as a true stereo amplifier where STEREO both of the two independent amplifier channels Channel 1 and Channel 2 can receive different 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 signal with a true 700 watt output into a single 8 ohm channel in the case of the S700 or a true 1000 watt output into a single 8 ohm channel in the case of the S1000 WARNING Bridged mode is to be used only when the S700 S1000 is connected 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 Bridged Mode The illustration on the right shows how this works In Bridged mode the INPUT polarity phase of the Channel 2 output signal is reversed relative to that of A gt 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 effective voltage swing seen by the load2.
