Some additional and useful features are,
1. Source can be renamed
2. Each source volume can be adjusted and maintained seperatly
3. Source DB level can set to fixed, this is very useful connecting AVR pre-out to integrated to drive front speakers. I have done this and home cinema become better than before
Amplifier burn-in myth ? Saw this on carton box of CA 851A
Someone asked this question @ their FAQ section,
Question
Running in the amplifier - why?
On my amplifier box it says that i need to run the amplifier for at least 36 hours constant for optimum performance - is this the case or can i just use my amplifier normally and over time this 36 hours will build up?
Answer
The running in process is to allow for the time taken for certain components (such as capacitors) to settle and perform at a constant. The amplifier will sound good out of the box, and will only improve as it is run in. This running in time can vary, but we generally quote about 36 hours.
You can do this all at once if you want your amplifier to be run in quickly, or you can use your amplifier normally and allow the 36 hours to build up over time. The overall result is the same.
