Test Tracks

Here's the one we've all been waiting for: A ceramic cartridge USB turntable. It didn't disappoint. smile.gif

The Crosley did a particularly bad job with the digitally mastered records. The Gorillaz sample sounds like someone applied a crude flange effect.

Worse yet, it skipped five times in the Gorillaz track (two can be heard in the sample). I replayed the track on the Ion turntable just to make sure it wasn't the record. It wasn't.

It made me wonder what's responsible for the skipping. The tracking force seems appropriate: 4.62 grams where, according to Garage 'A Records, the range is 2 5 grams. It could be poor anti-skate adjustment but the channel balance, while by no means perfect, seemed a bit better than the AT turntable.

I'd love to hear your insights on why skipping is such a problem on this loudly recorded LP. Skipping is not a problem on any of the other records I tested with.

The playback is so bad, I wonder if all ceramic cartridge turntables are this bad or just Crosley. I'm inclined to run out and get a different manufacturer's ceramic cart turntable. Grace Digital Audio, I'm looking at you!

Playback problems aside, the Crosley also arrived with serious defects.

As I moved the tonearm over the record to do my first needle drop, a funny thing happened: The platter didn't move.

The power light was on; I could hear the motor running. But the platter wouldn't spin.

I suspected the problem was the belt, which is not accessible without opening up the case. I had a choice to make: Should I play the average consumer and send it in for warranty repair or should I crack it open, voiding the warranty, and see if I can fix it myself?

I opted for the latter.

Sure enough, the belt had slipped off. I reattached it and the platter was rotating once again. I also got some good photos inside the box.

Another problem was the hinges holding the dustcover to the main unit. The metal was bent and the dustcover would fall off unless rested gently. I took it off for the samples.

So far, the Audio-Technica was the only turntable that I didn't have to fix anything on. The Ion turntable arrived with the cartridge and stylus detached.

One last note: The Crosley has built-in speakers along with a tone and volume knob. These knobs have no effect on the analog to digital conversion. I believe they split the signal before it hits the A/D converter. Of course, if you're interested, you can see the two circuit boards in the photo (I have more if you're really curious).

I looked at the Gorillaz LP from all angles and can't find any deformities. This is a new, 190 gram LP in great condition.

My bet is the sheer volume level at which this album is recorded plays a role in the skipping. The waveform on HFN002's "torture test" (at +18dB) is so erratic, the stylus must have been jumping all over the place!
