Pit1994 Posted June 25, 2014 Share Posted June 25, 2014 I am not able to record a simple guitar sound of my HD500X to Protools 11 via the S/PDIF input of the Firewire 1814. The firewire 1814 doesn't get any synced signal! I connected the Line-6 HD500X to the firewire 1814 input (breakout cable connector, MIDI–S/PDIF–WordClock-input) via coaxial cable (3m, 75 Ohms). The S/PDIF out (HD500X) is well configured. The device screen shows: 1. S/PDIF: matches Outputs 2. Sample rate: 44,1 kHz 3. Level: +0 dB 4. Input-Recording: 1-2 Main Out The Line-6 software control panel (Audio-Midi-Devices 3.61) shows the following Asio settings: 1. Default Buffer Size: 256 2. Default Bit Depth: 24. The Firewire sound device is configured via the M-Audio software-control-panel: 1. sample rate: 44100 Hz 2. Asio buffer size: 256 samples 3. Input: spdif 4. Output: spdif 5. Input port: coaxial 6. Sync source: external - digital When I change the Sync source from internal to "external-digital" then the green message "Locked" changes in to red blinking message: "Unlocked" (Protools not yet launched)! Additional Informations: PC- Windows 7 Home Premium; Firewall Antivirus: deactivated; Driver: Pod HD500X: 4.2.7.1 Driver: Firewire 1814: 5.10.0.5058 Protools version: 11.2.1 Can anybody help me?

DeanDinosaur Posted June 25, 2014 Share Posted June 25, 2014 Check the documentation of the Firewire device : Connect the coaxial S/PDIF output of your external digital audio device to the FireWire 1814’s rear panel coaxial (RCA) digital input. Make sure that spdif is selected as the input under the digital port selection, and that coaxial is selected for the spdif input port. Also make sure that external digital is selected as the sync source in the FireWire 1814 Control Panel’s page. You may alternately use word clock if your S/PDIF source has a word clock output or is locked to the same word clock master Quote Link to comment Share on other sites More sharing options...
bjnette Posted June 25, 2014 Share Posted June 25, 2014 Yeah and double check that the device is set the same sample and bit rate as the POD HD. You might have to disable any line 6 control software and let the interface software determine. Whoops: As I posted I realized your bit depth is unmatched. In s/pdif it is 16 bit only. unless someone knows how to change it? So select 16 bit on your interface. Quote Link to comment Share on other sites More sharing options...
bjnette Posted June 25, 2014 Share Posted June 25, 2014 I rechecked the Advanced guide and it says the s/pdif is a 24bit output but this is not the case. It will only work on 16bit. 24 bit is unselectable via Motu2408Mk III in s/pdif mode. This is not the case for analogue inputs on my interface. They can be configured to 24bit. If it bares out with others on any interface it is a false claim. I always thought it was peculiar to my setup. Quote Link to comment Share on other sites More sharing options...
DeanDinosaur Posted June 26, 2014 Share Posted June 26, 2014 MY HD500 SPDIF works perfectly using 24 bit 48KHZ with EMU Audio Interface. Quote Link to comment Share on other sites More sharing options...
bjnette Posted June 27, 2014 Share Posted June 27, 2014 Good to know Dean! So it is peculiar to my setup then. Cheers Quote Link to comment Share on other sites More sharing options...
