Presonus Audio electronic 26x26 FireWire Recording System user manual Hardware Settings

3 Control Console

3.4 Hardware Settings

Click on the Hardware Settings tab to access the following:

1.) Sample Rate (PC Only*): You can set the sample rate to 44.1, 48, 88.2, and 96k. When set at higher than 48k, the ADAT channel I/O is limited to 8 channels utilizing both ADAT ports and the Dual SMUX standard. A higher sample rate will increase both the fidelity of the recording you will make and the subsequent file size for every audio file.

2.) Buffer Size (PC Only*): You can set the buffer size from 64 to 1024 samples per buffer. The buffer size will affect the latency (roundtrip time it takes audio data to go into the computer and get processed back out to the FIRESTUDIO). The lower the buffer size is set, the lower the latency will be, and the higher the stress will be on your computer. Thus, if you experience digital ‘pops and clicks’ in your audio playback, try adjusting the buffer size higher to reduce the stress on your computer.

*When using a Mac and OSX, the sample rate can only be changed in the Audio MIDI Setup Application. Buffer sized are changed in your DAW.

3.) Clock Source: The clock source setting will determine where the FIRESTUDIO is deriving its clock. Unless clocking to an external device, the clock source should be set to Internal. You can choose between SPDIF, ADAT 1, ADAT 2, or Word Clock when selecting an external clock source. The FIRESTUDIO will sync to the samplerate the external device is set to when switched to any of the external clock sources, and the sync light will be blue if it is in sync.

4.) Terminate BNC: Check this box to terminate the BNC Word Clock input. This may need to be done to achieve stable sync depending on the external device you are syncing to via BNC Word Clock.

5.) Reset Names: Clicking on this button will reset all user-defined names in the Control Console.
