| 425288 | 2006-01-28 00:31:00 | Is there a Impedance match available on the market so I can connect the output of the sound card (mother board in fact) to my stereo system, so I can play the stored music (from Music CDs) on the hard drive. | Eric (378) | ||
| 425289 | 2006-01-28 00:43:00 | The line output of the computer sound "card" will connect to the line input of your stereo. The voltage and impedance will be right. Or "close enough for audio", anyway. You might need a stereo 3.5 mm to 2 RCA plug cord for this. Jaycar have them. It might be marked "Ext in", "Tape In", "CD in", or even "DVD in" on the stereo depending on its vintage. |

| 425291 | 2006-01-29 00:25:00 | The actual impedances don't matter all that much in audio at line level (around 1 V) . I don't think you'll have an input at 250k, even with a valve preamp . More like 50k (or 47k ;)) for a turntable input, and 10k or so for a line input . It's fairly arbitrary . ;) A turntable input will have a RIAA nonlinear response . . . and you'd probably be overloading it anyway . A 'Line Out" and a "Line In" will be matched . Full stop . A "Speaker Out" or "Headphones Out" will probably drive a "Line In", if the level is OK . The mismatch between 8 or 32 ohms and 10k or so won't matter . A "Line In" is supposed to have "flat" response . A "Speaker Out" on almost all modern sound cards is actually a "Line Out" because it's meant to drive amplified speakers, that is, a line-level input amplifier . It may be switchable . If it's light on bass, that may be a well meaning attempt to reduce the effect of "Sub woofers" . Tone controls? |

| 425292 | 2006-01-29 02:58:00 | At home i run flaptops "headphone" output directly to either the input of a mixing desk, or directly to a DI box which provides a balanced output at microphone level, and breaks the earth thus avioding noize issues. The latter is only needed because my set up involves the whole house and feeds balanced mic inputs. At home i'm not feeding the sterio by the computer desk. Lets just say that i am lucky enough to have a neighbours who appreciate my sterio.... They report no shortage of bass at all!!!! :D Here i'm running a 3.5mm sterio jack plug direct into the nasty little amplifier that a friend left us before she went to Oz, works fine. If your lacking bass, i wonder if your running a 5.1 soundcard, where some or all the bass is diverted to a sub that may or may not exsist? |
