HD580-650) can be useful for attachment directly to some of the more robust line outputs around, without the use of any headphone amplifier at all. Their impedance is high enough and flat enough that being driven by say 75 ohm impedance sources only...

Is the GTXP6.1's breakout box's headphone jack amplified and or up to what impedance of headphones can it drive without an addon amplifier. I'm looking into getting some nice headphones but i need to know the answer to this first. nVidiot: Message board...

impedance with speakerimpedance. You know speaker impedance is quite dependent on frequency. You know amplifier impedance normaly is about 1% of the speaker impedance. You know no amp or speaker has internal wiring or connectors with low characteristic...

the hell out of it? You have the microphone part of the system that is required to get the sound out, so to speak. The U47 uses a vacuum tube within the microphone shell as an amplifier and impedance converter. That tube requires rather high voltage...

I know that the PC is receiving the input. What am I doing > wrong? >> Thanks in advance. >> Peter Ledden > The Mic/Mixing jack is probably an input. The headphone jack is output, but it is amplified and impedance matched for a headphone, and is not...

discussion on this and other audio newsgroups. This post is not on that subject, and I for one would appreciate not seeing it creep into this thread, as this subject gets enough play already. I t occurred to me that in all this hubub about amplifiers...

guys' speakers - bad sounding speakers will mask an amps sound. 2. The person will equalize his amplifier - since his amplifier has sound qualities he has to equalize to sound flat. Archived from groups: rec.audio.high-end () >From: nousaine@aol.com (Nousaine)...
