Optimod PC 1100 vs. 1101

E

EP

I am planning on buying one of these cards and I'm wondering what the difference is between the 1100 and 1101 versions.

Also, is there any way to disable the music/speech detector?
 
There's no speech mode on/off button per se. You can set the controls the same as for music, which would effectively make it irrelevant what the detector decides.

As for 1100 vs 1101, if I'm not mistaken 1101 is a replacement for 1100 meaning you won't be able to buy 1100 any more. The new card has more powerful DSP on-board and is available in both PCI and PCIe form as well. I'm not sure what are all the differences exactly, but the 1101 has two WDM drivers (appearing as two sound cards in Windows) and the software features CBS loudness controller (used for TV processing) which 1100 does not.

Goran's post is correct in all aspects. The only things I can add are:

(1) that the 1101 fits in a 3/4-length PCI slot (which makes it work mechanically in more computers than the 1100, which required a full-length slot);

(2) the 1101's CBS Loudness Controller has some improvements (the most important being an attack time control to allow the user to tailor its loudness control to the programming it is processing);

(3) the 1101's processing algorithm is based on the one used in our 6300 and 8585 processors and adds soft knee compression to the 1100 V2's feature list;

(4) the 1101 has a sync input that can lock its internal DSP master clock to an external reference, including AES3, AES11, 1 x wordclock, and 10 MHz. This feature allows the 1101's wave input and output to be locked to a reference frequency, whereas the 1100 could only lock its external AES3 output to a reference frequency, which was done via the digital output's sample rate converter; and

(5) The 1101 has two AES3 digital outputs, whereas the 1101 had only one such output.


The 1101 is a replacement for the 1100, which has been discontinued for almost a year.
