Hello everyone, 1st post but lurked and followed the advice here for many, many years. thank you!
I've been having a horrible time trying to configure the Line outs 1&2 on my Mbox to simply output clean audio, and be the monitor outs for my brand new Yamaha HS7 monitors.
What I'm trying to do:
Use the default monitor output setup of my mBox Pro 3 (using outputs 1 & 2 as studio monitor outputs, volume controlled by front panel knob)
What the problem is:
Despite all meters telling me otherwise, and not touching any controls, Line out 2 (the right output) seems to be 50% lower volume than Line out 1, repeatedly, when they should be 100% even and at equal volume, and the driver settings have been unchanged. The internal digital meters show everything to be fine, but what comes out the Line Out jacks is a mess. It also seems to suffer from some harsh digital cracks. The crackling is intermittent, but lowered output on Line 2 out R is constant.
I at first thought it was new cables or the new speakers, but after testing the speakers for several days with every stereo and mono source I could find from iPhones to cassettes, with no problems, the culprit seems to be the Mbox Pro 3.
Before anyone says the obvious, the HS7s were set to unity volume with no adjustments- and they put out 100% evenly on other sources (like iPhone.) I've tested it in Pro Tools, outputting the mac's audio through it, Garage Band, they all seem to have the right output as 50% or more lower, yet meters and drivers settings all show it to be normal. I swapped all the cables and speakers around and still found Line 2's output to be much, much lower than Line 1, despite it being a mono sound source dead center panned. I pulled up a L/R balance test from YouTube, and still had the lowered output on the right. I put the mbox pro 3 into MONO mode and while the file was outputted mono on both channels, Line 2 still had this strange dip in level. I also thought it might be my Apple branded thunderbolt-to-FW800 adapter but the problem seems to happen no matter which FW input I use (the FW800 or the Thunderbolt.) Cycling through the clock sources in PT (which usually fixes any digital clock issues that show up) doesn't fix anything either. Looking at the driver, which I have not changed any settings on, it shows outs 1+2 and the master section to be both correctly hard panned and at unity, just as they should be to reproduce main mix L/R outs.
My signal path is Pro Tools ----> Mbox Pro 3 ----> Line out 1 + 2 -----> 1/4" TRS cables -----> HS7
The only other item in this system not mentioned is an iLok, and the problem happens regardless if PT is reading 44.1k, 48k, 96k, or YouTube audio.
My system is:
MacBook Pro,
OSX 10.8.3
2.7GHz Intel Core i7,
8GB 1600 MHz DDR3 Memory,
Pro Tools 11 version 11.0.2
Any help is appreciated, any more information needed just ask!
I haven't had any issues with outputs 1&2 before, and this mBox's multiple configurations is baffling compared to my old 003- which was 100% rock solid and issue free across 3 PT versions. I have several complex mixes due soon and at this point after a week of issues, I've already lost lots of hours of work, and thus pay. At this point I am stuck, can't fix it, and work has completely halted... please help!
Thanks!
