Apogee Symphony I/O - Firmware/Software Release 4.1

I've installed Release 4.1 firmware/software to my Symphony I/O. It's made a significant improvement to the fan noise. And a welcome new feature is a low latency mixer for the Symphony 64 PCIe card mode. With this it's possible to listen to analog input signals from the front panel earphone jacks while rehearsing or tracking. Previously this was possible with USB mode.

In order to pass audio through the low latency mixer, it will be necessary to open up Maestro 2, click on the Output Routing tab, and drag line 1/2 (or whatever channels you use), down to Mixer 1 or Mixer 2.

Very excited about trying this out after the holidays.

Is it possible to setup queue mixes to a separate set of outputs (3/4) for musicians while I monitor the mix?

Also note that there's a kit for minor modification of the chassis - blocking the left-hand vent holes to better direct airflow through the chassis. If you fill out their form they'll send you a specific material to use for the mod. See page 2 of the 4.1 release notes for more info.

Freaking awesome, I have missed the low latency mixer so much.

Regarding the fan noise, is it down to levels where it can be in the same room for tracking, or is isolating it still advisable?

Re the fan noise and tracking, i guess it depends on the application and proximity. The fan noise is quieter and steadier but not inaudible. I was doing some compressor testing with an LDC sitting a cubit from a twin module Sym IO and the fan noise was clearly audible in headphones. But with the mic on the other side of the room for rock vocals it would have been all right I think. This was with tape over the left hand side vents, to drag intake air over the modules.

Makes sense, what cards are you using?

The two modules installed are the 8 analog IO/8 optical IO and the 16 analog out/16 optical in. This box generates some heat when its working. A friend who's into astronomy suggested I look at after-market water cooling for the ADDA chips. Might be worth investigating - though, the fan noise after the 4.1 upgrade is about the same as the Windows box on my desk here at work. Or about the same as my MacPro, just steadier.
