AHosted Mode – Sample Rate

This drop-down menu sets the sample rate of ProFire 610. Note that when using the interface with an ASIO or CoreAudio application, the sample rate can also be determined by your audio application. This parameter may not be editable from within the ProFire 610 Control Panel if your audio application is running. In this case, any changes to the sample rate must be made through the audio application itself. If the application does not provide a way to set the sample rate, quit the application, then change the sample rate through the ProFire 610 Control Panel.

If ProFire 610 is set to External sync, this menu will display the current incoming sample rate, and selection will be disabled. If the unit is set to External sync and an error is detected in the incoming sample rate, the field below the menu will display one of the following two messages:

•Unsupported – an unsupported sample rate is detected

•Unlocked – no valid clock source is detected

If External sync is selected and a sync error is detected, the Power LED 8 will blink.

Hosted Mode – ASIO / WDM Buffer Size

Windows Only

Latency is defined as the time it takes for your input signal to pass through your audio software and appear at the outputs. This latency can result in a delay that is undesirable when overdubbing to existing tracks.

This drop-down menu lets you select the size of the buffer in samples. Smaller buffer sizes result in lower latency, but may not function well with slower systems, causing clicks, pops and dropouts in the audio playback.

The default buffer size is 256 samples. If you are experiencing clicks and pops in your audio, try increasing the buffer size.

Standalone Mode – Sync Source

This drop-down menu lets you select the digital clock synchronization source while operating in Standalone Mode. You can choose to synchronize to the internal clock of ProFire 610 or to have the interface lock to an incoming S/PDIF signal.

Standalone Mode – Sample Rate

This drop-down menu lets you select the sampling rate of the interface when operating in Standalone Mode. Supported sample rates are 44.1, 48, 88.2, 96, 176.4 and 192 kHz.

About External Clock

Digital audio is based on samples. For example, a digital recording at a sample rate of 44.1 kHz contains 44,100 samples, or digital “snapshots,” per second. Each digital audio device has its own internal clock, or crystal, to generate and control the exact rate and timing of these samples during every second. In order for two or more digital audio devices to function together, only one of their clocks can be in control (the Master), while any other devices must be synchronized to that device’s clock (the Slave). Otherwise, the resulting audio will sound distorted, play at the wrong speed, or have clicks and pops.

You can set ProFire 610 to run as the Clock Master (“Internal”) when digitally connected with other digital audio devices:

Connect ProFire 610’s S/PDIF output to the S/PDIF input of another digital audio device and configure that device to synchronize to its S/PDIF input (making it the word clock Slave).

Alternatively, you can set another device to act as the Clock Master and designate ProFire 610 to run as the word clock slave:

Connect the S/PDIF output of your digital audio device to the S/PDIF input of ProFire 610. Select ”External - S/PDIF” as the clock source setting on the Settings tab of the Control Panel. ProFire 610 now runs in sync to the digital S/PDIF signal generated by the other device.

If ProFire 610 is set to External Sync in Standalone Mode, the Sample Rate menu will display “Auto” and the interface will automatically lock to the incoming S/PDIF signal’s sample rate.

If External sync is selected and a sync error is detected, the Power LED 8 will blink.
