An adjustment to the speaker impedances enables higher output power to various speakers of different impedance. In a conventional amplifier which is designed for 4 ohm speaker impedance, the output power will drop sharply when using 6 or 8 ohms.

The nerve cells signal muscles in the large intestine to push stool toward the anus.Without a signal to push stool along, stool will remain in the large intestine.1  In a healthy large intestine the nerve cells are found throughout the large intestine. 2  Short-segment Hirschsprung disease. 3  Long-segment Hirschsprung disease.ithout a signal to push stool along, stool will remain in the large intestine. 1  In a healthy large intestine the nerve cells are found throughout the large intestine. 2  Short-segment Hirschsprung disease. 3  Long-segment Hirschsprung disease.
