I took a test tone and tried to match the two to get a accurate level. First off how do you get a accurat level in protools. I brought up a waves metter but it shos the level around -16db. It is hard to tell exaclty. I need to see a number. Is there a reason why the Hedd level is hotter? |
best way:
buy a multi meter with enough resolution to read 1.228v. for post (in the U.S.)-20dBFS for recording music -18dBFS = 0 VU (or +4 dBU, or 1.228V)
then roll up your sleeves.
create a new session, whatever bit depth SR you want. select either your A or B trims in the HW dialogue.
new mono aux track, input set to none. assign output to mono out 1. put a signal genny plug-in on the track. set the Genny to -18dB at 1kHz. keep aux track's at fader at unity (0dB).
create as many mono aux tracks as you have analog outputs. assign the input of all these aux tracks to bus 1. cascade the outputs of all these auxes to your outputs starting at output 1 and ending at output X
***IMPORTANT: make sure to use mono outputs not stereo outputs***. Put those faders at unity (0dB).
Using your TRUE RMS voltmeter measure the AC voltage at output 1 -- adjust the A or B potentiometer for 1.228v on each output.
192's are NOTORIOUSLY mis-calibrated form the factory. in fact, high school, they were voted "miss-calibrated"
then you KNOW that it is right ANLOLOG wise.
the A trims are for one set of cal's the B trims are for another set. say you do music AND post. A= -18dBFS B= -20 dBFS.
