My early impressions of the Quant Asylum QA401 - so far, very impressed. Don't know how I did without something like this for so long. Very intuitive to use, had it up and running in minutes. I've spent more time making BNC to XLR cable adaptors! Used the frequency response FFT to get rid of a HF rise in a mic pre input transformer. Made easy work of that.
Software is easy to use as well. All in all a great product. Super value for the price.
OK, what I would like to see added:
- 150 ohm and 600 ohm outputs, in addition to the 47 ohm output. I've made cables with buildout resistors to provides those loads to the mics preamps (150 ohms) and vintage outbard gear (600 ohms) I test.
- Measurement units in software include dBFS and dBV. I don't see much use for dBFS on an analog tester, but that could be a function of my ignorance. I would prefer dBu to dBV, or just to add dBu as a choice. I consider dBV more of a consumer voltage reference.
- offer the choice of higher output of the impulse on freq response measurement. I find gear sometimes responds differently at different input levels, and would like to have the choice to test those different levels.
Pretty nitpicky stuff though. All in all, I would still buy it again without reservation.
One more thing - Mark at QA tech support have been super helpful and responsive. Nice to have good customer service.
