Sorry, but I could not help myself -- those specifications SUCK -- aside from speaker output power. Signal to Noise of 80 dBA (cd spec is 100 -- no wonder most people think MP3s sound good) 10k ohms is 10 times more resistance than 1k (average and still crappy).

Don't believe me? Let's plug that puppy into a board and compare it to something with 5V @ 100 ohms not 10K!

 

One thing I like about my panasonic is 5v Pre-Outs at 60 ohm
the s/n is 96db too... funny that a panasonic would have beter specs than the alpine

 

first of all, Alpine rates their pre amp outputs with a 10 kohm load, not with an output impedance number, that way you know that the pre-outs will deliver x volts into y load of a typical input impedance, and not just 2 volts at some magical load that may not deliver anything close to what it says at typical input impedances. second, the 80 dba rating is for the amp section, all newer Alpine cd players are rated at 105db s/n from their cheapest unit right up to their expensive ones. f#1 is at 115 db for the older cd unit. Just go to their website and download one of the manuals, it's all right there. Third, you don't win more sound offs than everyone else put together with noisy equipment!!

 

1. Output impedance is the resistance against the voltage coming out of the deck -- less impedance means more voltage gets through

2. 80 DB for the amp is still crappy (80 db is what most radio sections are rated at)

3. Loss voltage with high impedance is a great way to introduce noise into a system -- if you have more voltage, you need less gain -- less gain, less potential for noise and overdriving the amp.

 

1. they have not given a rating for output impedance. They have essentially guaranteed that you will get 2 or 4 volts with 10kohms of resistance. I prefer to know what I'm getting at least, than to not know what happens when a high load is introduced.

2. That's dbA, as in "A" weighted. Add 20-30 to that number for db.

3. Possibly a big problem in poorly installed systems.

 

I think we need a whole new forum on how to read and interpret specifiactions. And lessons on the CEA standards, so that all manufaturers have a level playing field to compare against.
I'm glad someone picked up on the "/10k" meaning into a 10k load, and someone else picked up on the dBA, yes the "A" makes a big difference, and that that spec was for the deck power only, which you can completely power down anyway. I've never used the deck power.
But i don't think all that belongs here. There was a question asked and answered.

 

Thats how road gear competes with Alpines specs.
