Divergence • This control continuously varies the center image from dead-center (speaker 3) to a phantom-center (equally split between speakers 1 and 2). • With a Divergence setting of "0" the centerpanned channel is routed to the center speaker only (speaker 3). • With a Divergence setting of "100" the centerpanned channel is routed equally to the front left and right speakers (speakers 1 and 2). Low Frequency Effect • This control varies the channel send level to the subwoofer (speaker 4). • This is the only control over channel levels to the subwoofer (speaker 4). • The pan grid has no effect on this adjustment. • With this control set to OFF there is no send level to the subwoofer. • Unity gain is achieved when this control is set to "0.0". 6.1 • Notice the speakers are numbered 1, 3, 2, 5, 4, 7, and 6.
