Volume very low - ADAT Outputs - 828mk3

[ben00net]

Hi Everyone,

Hoping someone has the answer to this (i've searched the forums but haven't had any luck)

I'm using my 828mk3 to monitor my mixes and also as an additonal 8 inputs into my M-Audio Project Mix IO (PRE'S on this are pretty crap, MOTU is better)

For some reason the output volume on the ADAT channels is really low once it leaves the unit. The meters register ok, but by the time it gets to protools the volume is gone (ie around -30 on the meters in Protools)

Any thoughts on what could be causing this. The M-audio is also seeing the signal as very low, checking the monitoring software that this comes with (before it hits protools)

I've got the latest firmware version - driver doesnt matter as the unit is not connected to the PC as it's operating outside the function - i followed these instructions on the Motu website - Using a MOTU Audio Interface as a Standalone A/D or D/A Converter
If your MOTU audio interface has a standalone operation mode and digital audio I/O, you can configure it as a standalone analog-to-digital (A/D) or digital-to-analog (D/A) converter.

In this example, an 828mk3 will be configured as a standalone A/D converter using its ADAT optical output by patching its analog inputs to its ADAT outputs:

1.Connect the 828mk3 to the computer by FireWire, and turn on the interface.
2.Open CueMix FX. Choose the Inputs tab, and then enable the Stereo button on the channel strips for analog inputs 1, 3, 5, and 7. (They will now appear as Analog 1-2, Analog 3-4, Analog 5-6, and Analog 7-8.)
3.Choose the Mixes tab, and select Bus 1 in the mix bus menu.
4.Set the mix bus output to ADAT A 1-2 by selecting the output pair in the bus output menu above the mix bus master fader. Set the master fader level to 0 dB.
5.Mute all input channels except Analog 1-2. Set the Analog 1-2 fader to 0 dB. Set the balance control to 0.
6.Select Bus 2 in the mix bus menu.
7.Repeat the process with Bus 2 to route analog inputs 3-4 to ADAT A outputs 3-4. Then continue with Bus 3 (Analog 5-6 to ADAT A 5-6) and Bus 4 (Analog 7-8 to ADAT A 7-8).
8.Open MOTU Audio Setup. Set the 828mk3's sample rate and clock source appropriately.

The 828mk3's sample rate should match the sample rate of any connected digital audio devices. Generally, the 828mk3's clock source should be set to Internal when it is being used as an A/D converter. However, these settings may be changed under some circumstances.
9.Wait about one minute for the new settings to be saved to the 828mk3's internal memory, and then disconnect the FireWire cable from the back panel of the interface.
10.Connect the 828mk3's ADAT A output to the ADAT optical input of another device. If the 828mk3 is the master clock device, then set the second device's clock source to its ADAT optical input, and set its sample rate to match the 828mk3's sample rate.
