Cakewalk UA-1G and Griffin iMic
Has anyone here used the Cakewalk UA-1G USB audio adapter? While the Behringer
UCA-202 is good for the money, it does not provide audio level control for its inputs. Usually that limitation is not a problem, but for the current project, the level control will be helpful. Also, I've used the Griffin iMic (Version 1) for a lot of ad hoc projects, mostly involving playback. Over the weekend, I tried to use it on my HP Elitebook 6930P, and the computer would not output audio through it even though it provided input audio. The unit is quite dated, but so are most of my computers. It acted like a driver was wonked, but I couldn't find any drivers other than the default Windows drivers. |

The UCA-202 records all the significant bits it's capable of, and overloads at a little less than 2V. IF you want to add a level control it really needs to be an analog attenuator before the RCA inputs. You can simply increase the digital file level after it's recorded, or some audio programs will allow you to adjust the gain in real time if you're happy to take the chance on clipping. Trevor. |

Either there is a problem with my unit, Windows installed the wrong driver, or the input gain on the UCA202 is too low. For a totally unrelated reason, I plugged the headphone jack of a portable FM radio into the UCA202. Even though the volume on the radio was loud enough to finish destroying my hearing when using headphones, the maximum level was -22db though the UCA202. If it had been -12db, I wouldn't have complained. I expected it to be low, but not that low. The UA-1G will be here tomorrow, so at least I'll have a point of reference. |

You need to specify for the microphone that playback takes place via the usual soundcard. If you do not do that windows assumes that the usb sound source also is capable of audio playback. The unit is quite dated, but so are most of my computers. It acted like a driver was wonked, but I couldn't find any drivers other than the default Windows drivers. Should be all you need. Look at second time at all the option pages for sound. Kind regards Peter Larsen |

It should give you DFS at approx 2V, IF you want digital FS at a lower voltage you need a pre-amplifier, not a different driver. For a totally unrelated reason, I plugged the headphone jack of a portable FM radio into the UCA202. Even though the volume on the radio was loud enough to finish destroying my hearing when using headphones, the maximum level was -22db though the UCA202. If it had been -12db, I wouldn't have complained. I expected it to be low, but not that low. Seems a bit low, but without knowing the FM radio output, it's hard to say. Anything designed for high sensitivity earbuds for example will not get anywhere near the 2V required by the UCA202 for DFS. Most ADC's without pre-amps are even worse. (When the UCA202 is used in a professional set up with the much higher levels, it requires an attenuator). An ADC with a mic pre-amp front end is what you probably need, or simply use a cheap mixer as a pre-amp if you have one instead. The UCA202 was mainly designed to be used with a cheap Behrenger mixer, or the cheap Behrenger keyboards after all Trevor. |
