Yes, in most ways. The mixers are the same essentially. There can be more money in video, so the sound component typically uses higher quality gear.
Right now 32 bit 96khz sampling rate is studio quality. CD is 16 bit 44kHz. DVD is 16 bit 48kHz. It's a bit of a trick to "dither" down to...
ooops, got that wrong.
-6dB is half voltage and quarter power at the same time. They are all equivalent points on the same log curve. Amazing how hard it is to break a bad habit. Glad I got that mistake out of my head, finally.
Hi Jim:
The 0.775V reference actually came from CBS during the early days of television. Yes, 1mW over a 600 ohm load. It is the heart of the old VU (volume units) meter. It is now referred to as the -10dBV relative to 1V as 0dBV (do the math, you get .775V) reference. This is also known...
Hi folks:
Be careful here. If the original post refers to audio/sound (20Hz to 20kHz), then dB refers to voltage, not power. When referring to sound applications 6dB is half voltage (3dB is half power). dB(voltage) = 20 log (out V/in V). Power depends on load/impedance, which depends on...
