mike7731 Unregistered guest | What is channel separation, and is 63db good for a headphone output? THD < 0.05% SNR > 90db Channel Separation > 63db yay or nay? |

Separation is exactly what it implies. When a young couple are courting and talking to on another, they are said to be star "crossed". When a married couple are "separated", they do not talk to each other. Same thing in audio. |

Panama Canal ADVERTISEMENT waterway across the Isthmus of Panama, connecting the Atlantic (by way of the Caribbean Sea) and Pacific oceans, built by the United States (1904--14) on territory leased from the republic of Panama. The canal, running S and SE from Limon Bay at Colon on the Atlantic to the Bay of Panama at Balboa on the Pacific, is 40 mi (64 km) long from shore to shore and 51 mi (82 km) long between channel entrances. The Pacific terminus is 27 mi (43 km) east of the Caribbean terminus. The minimum depth is 41 ft (12.5 m). http://education.yahoo.com/reference/encyclopedia/entry?id=35824 |
