53 is very quiet. 54 & 55 are square waves ...rec wrote:Which of these sine waves should I be using from the Bink Test CD for setting the limiters on my tops
52. 1kHz inverted polarity
53. 1kHz -60dBFS
54. 1khz Square -2dBFS
55. 1kHz Square 0dBFS
You could use 52. But why not just use track 5, 1kHz?Instructions for using the Bink test CD wrote:Tracks 54-55: Square Waves. Watch out for these tracks! Turn your amps off first! Square waves are sometimes used in destructive testing at audio R&D labs... Don't run them at high volumes if at all. The most vulnerable part of your system are the HF drivers which can fry with square waves! These tracks are useful in setting CD input trims. If your channel input doesn't distort from Track 55 (which slams in at 3 dB above digital ceiling!), it won't distort from nearly any commercially available CD out there. You can also listen for crosstalk on other channels -- it comes through most severely with square waves in neighboring channels. It is not ever necessary to send square waves out to amps and speakers in a normal live sound setup situation.
