Hi Scott; I have defintely heard of this being done. What is important here is that the CD player has a variable output controlled by a remote which you have. I would turn the gain controls on the power amp to full. Yes, you do not have a pre-amp as your middleman for this method. Some purists think this is a great way to listen to your cd player. The question here I believe has to do with impedance matching. The impedance from the output of the player I believe is quite different than the impedance from the player going thru a pre-amp.
Heart Rate. An adult catâs heart normally beats 140 to 220 times per minute with an average of 195 beats per minute. Newborn kittens have a heart rate of 220 to 260 beats per minute. To check your catâs pulse rate, put your hand on the inside of the rear leg at mid-thigh. You should feel the femoral artery pulsing near the surface.
When we listen to your cat's heart, we are listening for the rate, rhythm, and sounds. A normal cat heart rate is about 120-150 at home, and about 150-220 at the vet clinic due to stress. The sound should be crisp and clear and have a regular pattern to it. The heart has four chambers, two ventricles and two atria. The lub dub sound that we hear when we listen to your cat's heart is the closing of the valves as the blood is being moved through your cat's heart. Anything that changes how the heart pumps or that affects the valves closing can cause abnormal heart sounds. Today, when we listened to your cat's heart, we heard: Heart murmur / Heart arrhythmia / Tachycardia / Muffled heart sounds / Pounding heart sounds.
