What do these specs mean for me?

post #1 of 4
Thread Starter 

What I have here are the output power specs for my Marantz SR6005 A/V Receiver. They e-mailed me the specs today and heres what they said:

 

Headphone Output Spec:
Frequency response: 10 Hz~100 kHz,  +1, -3 dB (mode DIRECT)
Max voltage output: 1V
Output impedance: 377 ohms

 

 

What affect do these specs have when using high quality headphones? 1v doesnt seem like a lot, and how does output impedance affect performance?

 

Sorry, I dont have the receiver or headphones in hand yet,...

Just looking for opinions on how well this would work for headphones.

Anyone?

Frequency response by itself seems probably just fine, not much reason to expect otherwise.

 

With some sets, 377 ohms output impedance would be drastically bad.  Others, not really a problem.

 

Max voltage output should probably depend on what the impedance of the headphones is.  1 V is kind of a low number, considering the output impedance is so high.  My guess would be that if it really means 1 V, that's for say 16 or 32 ohms headphones, which is kind of a "standard" impedance (but not really).  So hopefully it would be a lot more for higher impedance headphones, which is what you'd expect with a device with such a high output impedance.

If you have questions, ask.
