c. Three channel operation
This configuration demonstrates the flexibility of the PULSE 4x300. Channels 1+2 are bridged and drive a
600W 4 ohm sub-bass speaker. Channels 3 and 4 are used independently to drive two 300W 4 ohm mid-
high speakers using an external crossover unit between the mixer and the amplifier.
d. Four Channels Driving Two Actively Crossed 2 Way Monitors
Capable of driving a pair of 2 way monitors, the PULSE 4x300 is great for tour sound. As all channels are
used independently in this application, the speakers may be 2 ohm impedance if required. See section 7e
of this manual for more information about how to calculate impedance. A crossover to separate the
respective frequencies for the mid bass and horn drivers will be necessary.
