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 4 ohm speaker load. The BRIDGE MONO mode section on page 9 describes the special speaker connection used. Refer to (Figure 21 through Figure 23).

Examples:

Driving a single 8 ohm speaker with the combined 4 ohm power of both channels.

Driving a single 4 ohm speaker with the combined 2 ohm 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 4 ohms 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 2 ohm loads.

See the additional BRIDGE MONO mode warnings on page 9.

70 / 100 Volt Operation

The CMX 2000V can operate in 70 Volt or 100 Volt operation in STEREO mode or BRIDGE MONO mode. Please refer to the above section on BRIDGE MONO mode for proper setup and configuration. Refer to (Table 2) for the power outputs of these modes.
