I've built a new computer using an Aopen Cobra sound card.(Yes, it's
bottom of the line, but will serve temporarily.) Its output is 6.67 dB lower than calibrated signals I play from a test CD. Also, line inputs and audio signals from Winamp and Windows Media Player are too low compared to my old Ensoniq PCI card. All the mixer gains are at max. That's both mixers, the one with the sound card (C-Media) and the one available through Control Panel/Sound and Multimedia with W2000. Also, if I try to record loud, heavily modulated FM signals at the Line Input, the peaks are 6 dB below max. With the old sound card/mixer, I would have to set one of the gains at 2/3 to prevent clipping. I'm using the same amplified speakers as on the old computer. Any ideas what might be reducing the gain? Thanks, Ray |

I never understand why people buy a 50 horsepower car, understanding that it's 50 HP, and then go ask the mechanic why it won't put out 200 HP. You get what you pay for. |

So what is a 200 HP soundcard? I have a new PC with an intel 925XE MB (intergrated sound) that does not have a sound input point for my TV tuner card. I want to add a very good sound card so that I can have good quality analog input for recording my LP's, plus an on board input for plugging in the TV card. I guess the AOpen Cobra is not the go, but what is? Dave |

I guess the AOpen Cobra is not the go, but what is? If you really want to do it right, and work flexibly with a lot of sources, you'll probably route all of your sources including the analog output of your TV tuner card to an outboard mixer, and then record the output of the mixer with an audio interface that is designed for audio production. Actually, the best TV tuner cards don't have analog outputs, but record through their internal audio interfaces, such as the Diamond PVR 550. By using an internal audio interface, you ensure that the video clock and the audio clock stay in synch. http://www.outpost.com/product/4293404 A good "starter" card might be the Echo Mia or the M-Audio Audiophile 24192. A good small external mixer would be something like a Behringer MXB 1002. |

I never understand why people buy a 50 horsepower car, understanding that it's 50 HP, and then go ask the mechanic why it won't put out 200 HP. You get what you pay for. I wasn't expecting great things from it. Since the gains are low for any of the analog inputs, the problem is probably caused at a common stage of amplification. Typically, the gain through an analog amplifier is set by a resistor. The cost of the resistor doesn't depend on its value. So I can't blame it on the cheap price of the card. I'm not expecting the soundcard to drive speakers; but I do expect enough gain to record full scale and play back at a decent level. Actually, I had read in one other place that some standard changed a couple of years ago as to what voltage level corresponds to max out. I think it said only 1 volt is needed now, vs an old standard of 2. I was trying to confirm this. Thanks for the comment. Ray |

Its output is 6.67 dB lower than calibrated signals I play from a test CD. How are you measuring that? With an number like 6.67 dB, I'm certain that you're doing some sort of digital test. I have a test CD that has tones recorded at 0 dB and -10 dB. I play the tone, then record it with Cool Edit Pro. CEP has an analysis funcion that measures the average and total RMS power of a selection. It reported -6.67 dB for the 0 dB input. When I use CEP to record one of those loud disco FM stations, the peak readings on the level meter are around -6 dB, not 0. That's with the gain controls at max. With the old card, I have to set the record gain at about 2/3 max to prevent clipping. Plus, my ears tell me that the output is dramatically lower than with the old card. Also, line inputs and audio signals from Winamp and Windows Media Player are too low compared to my old Ensoniq PCI card. There is no standard input (or output) level that equates to digital full scale. You get what you get. Any ideas what might be reducing the gain? The design of the card. If you've connected it properly, there's nothing you can do with it. Turn up the volume control on your speakers if you want to hear it play louder. Doesn't solve the problem of not recording loud enough. The way things are now, every time I record something, I then have to waste time amplifying it to get the loudeness I need. Thanks for the comments. Ray |

So highest fidelity and S/N are not the highest priority, especially since after processing I convert them to MP3 (192k rate) for playback via my laptop's sound card. (May seem horrible, but for the 60+ crowd I play for, they are perfectly content.) My old Ensoniq PCI was just right. Unfortinately, I couldn't get it to work with my new computer with W2K, even with all the SoundBlaster updates, so I passed it along with my old W98 computer to a friend. I thought I read that some standard regarding voltage levels at max output was changed, such that the old 2-volt level was cut to 1-volt. I was hoping to confirm that. Ray |

I thought I read that some standard regarding voltage levels at max output was changed, such that the old 2-volt level was cut to 1-volt. Actually, there never really was a 2 volt standard. It's just that up until recently SoundBlaster consumer pack cards tended to have 2 volt max output, while the OEM pack cards only put out 1 volt. I haven't gone through the entire current CL line, but the new cards and USB interfaces that I've checked have been 1 volt devices. I was hoping to confirm that. AFAIK, roger. BTW, using a cheap mixer, you can easily bring the 1 volt output voltage up to just about anything reasonable. Here's something that could work, and is even cheaper than the MXB 1006 is ($99): http://www.samedaymusic.com/product--BEHUB802 |

Wouldn't cobbling up a small amplifier in a little box be the simple
straightforward solution? I mean the solid state kind, not adding a tube and transformers and a B+ supply. You know, a couple of transistors, resistors, caps, or a decent op amp even(!). Nothing tweako. It's for a goddamn deejay. He's playing MP3's. |

I was a little surprised when the new Intel MB didn't have an analog input on the board, like a lot of other sound cards. I might go the Soundblaster route, but Arny Krueger's suggestion of routing inputs through a mixer and out through a decent sound device looks good. A lot of my old tapes will need some work, and I might have some fun along the way. The chosen solution: a cheap Soundblaster card to satisfy the TV card input problem plus an Mbox/protools for the home recording. Dave |

I use to have a SB Live card which I bought as a temp until I decided what card I was going to use. The first thing I noticed was the significant increase in output level with the 24/192. I now set my monitoring fader of my Mackie 1402 to about half of where I normally have it with the SB Live card. The 24/192 is smoother and richer sounding. It makes the SB Live sound like the old cheaper CD players where the lows are too boomy, the highs are too harsh and the midrange is thin. As far as recording goes, I still need to experiment and play around before I can give it a fair assessment. I'm pretty confident this card will suit my particular needs. I took a chance on this card based on the specs without listening to it. So far I like what I hear. Stan |

I can confirm all of your perceptions as follows: That depends on the settings on the M-Audio control panel. The SB Live! comes in a number of models which I will categorize as the OEM models and the consumer pack models. The OEM models have 1 volt maximum output and the consumer pack models have 2 volt maximum output voltage. In contrast M-Audio Delta cards have up to three different output level settings. The highest of them is called "+4" and ranges from about 3 to 6 volts depending on the model. The lower ouptut voltage settings are called -10 and consumer and are as low as 300 millivolts. The 24/192 is smoother and richer sounding. It makes the SB Live sound like the old cheaper CD players where the lows are too boomy, the highs are too harsh and the midrange is thin. I suspect that the frequency response of the Audiophile 24/192 is almost perfectly flat within 0.1 dB 20-20 KHz which is very fine. Again, depending on which model of the SB Live! you have, there are some fairly significant ups and downs in the frequency response curves. These technical reports detail them: http://www.pcavtech.com/soundcards/live!/index.htm That these variations can be heard in a proper level-matched, time-synched blind test is demonstrated at: http://www.pcabx.com/product/ct4830/index.htm As far as recording goes, I still need to experiment and play around before I can give it a fair assessment.

IMO, Consumer should be 1-2 V FS. http://www.m-audio.com/images/en/man...0LT-Manual.pdf puts it at -4 dBv (page 37). I believe there is still 10 dB headroom (page 9) , so FS is +6 dBv or 2 volts. |
