First off, thanks for all the response. Thanks to 4yanx for clearing up the question on dougdeacon's response. I always thought there must be something wrong with me cause I could never get all of the "esoteric" clues and directions on those test records. I also use regular records for testing also, especially adjusting VTA. I once read a thread were TWL suggested using your ear to adjust VTA, I never thought I could do it but I have gotten better. Shoot when I first started down this road I thought the VTA riser I bought for my Rega was to raise the cartridge to clear the record for when I was using the cueing function on my table. Matching cutter head angles meant nothing too me. I also found an interesting article on anti-skate, "buzzing in the right channel indicates more anti-skate force is required, whereas buzzing in the left channel indicates that less anti-skate is required." (audiophilia.com/features/cartridge-setup.htm) In this same article he mentions the HIFI record azimuth test. He states to adjust the azimuth until the signal is deminished. Lugnut, I do use the turntable basics mirror alignment tool for cartridge alignment, I guess now I can use it to check azimuth also. 4yanx I will try using the turntable basic's mirror for the azimuth test that you mention, also. Thanks TWL for reaffirming every one else's views too. I will also check on the cantilever angle when I get home at 5:00 am and start my listening session! happy spinning
Azimuth&Bias on HIFI test record
I bought a used Grado cartridge on the 'Gon. When I go to set it up, everythings runing smoothly VTA, tracking force, alignment. I then listen to the HiFi test record to test azimuth and bias. Concerning azimuth, the text suggests that the test tone should disappear, when the amplifier is switched to mono, because the signals will cancel each other out. Now my question, should there be dead silence or just a reduction in the test tone? On my set-up, when I push the mono button the tone is greatly deminished but, not completely gone. Concerning bias, on the test record they have you listen to a test tone. Supposedly you adjust your bias/anti-skate to smooth out the high frequency test tone. On my system the tone seems to modulate. Do I increase the bias until the tone stops modulating? Would like any advice from those that have experience with using test records. The Grado Platinum is mounted on a RB300 which is attached to a P3. So what's the scoop Analog elders?
