ProFire Lightbridge WITHOUT a computer

[dortola]

Hi!

I’ve bought the ProFire Lightbridge to monitor my Alesis HD24 and to have a backup recording on my laptop. But in some situations, I just need to monitor what’s going on with the HD24 without using my laptop, through the ProFire Lightbridge headphones. The question is: Is it possible to use it without a computer? Is it fully functional to monitor the "adats ins" without the firewire connection? Of course I use the power supply, so I don’t need the firewire bus for that.

I have an Alesis HD24 and three Focusrite Octopres, and I use just the adat connectors.

Thanks!

Most firewire interfaces claim to work if the computer isn't connected. You need to connect them to the computer to set up routing etc first though. Read the Manual, it will tell you.

I've never tried with mine, but I guess it's not going to work, as you need to install a driver and use it from the computer to set it up: activate/deactivate ADAT ports, clock settings, analog and SPdif I/O...it doesn't have any switches on the front panel (except volume pots, power and HP out)...everything is done via software...
My setup si similar to yours; I use the dual ADAT ports on the pres (Octopres and ISA) to go to both the HD recorder (I have a Mackie SDR) and the lightbridge. So I monitor off the lightbridge/PT combo. I also have a smal rackmount line mixer that I use to monitor the SDR analog out, but once I have verified the signal coming out is OK I do my monitoring/rough mix in PT; after all it's all digital form the pres down the line...so if it's all clocked and synched it's OK. If there's some issue in the analog part (mic or pres) i'd be hearing that too on the PT mix since it's the same exact signal that goes to the SDR.

Hope this helps
