Bridge Mono Mode
This mode combines the full power capabilities of both channels into a single speaker system. The amplifier internally re-configures so that both
channels operate as a unit. This delivers double the output voltage, resulting in four times the peak power and three times the sustained power into a
single 8 or 4Ω speaker load. The Bridge Mono mode section on page 7 describes the special speaker connection used.
Examples:
• Driving a single 8Ω speaker with the combined 4Ω power of both channels.
• Driving a single 4Ω speaker with the combined 2Ω power of both channels.
Precautions:
• Bridge Mono mode makes it possible to drive thousands of watts into a single speaker. AC current consumption will usually be higher. Avoid
excessive signal level, and make sure the wiring and speaker can handle the power.
• If the load is 4Ω or less and prolonged overloads occur, the amplifier will probably mute for several seconds during peaks, and the circuit breaker
may trip.
• Do not use 2Ω loads.
• Ensure Channel 2 dip switches are set to off (Figure 18), and Channel 2 attenuation control is set to maximum attenuation.
See the additional Bridge Mono precautions on page 7.
Set Channel 2 dip switches, 8 and 10, to off.
