AudioFuse 8Pre - Tips & Tricks

af-8pre
Here are some AudioFuse 8Pre tips and tricks.
You will hopefully find these useful.

In standalone, you can also switch modes easily from the front panel:

• Press the Mode button and hold it for 3 seconds.
• The LED of the current mode will begin to flash.
• When the LED of the target mode becomes lit solid, the AudioFuse 8Pre has switched modes.

If the AudioFuse 8Pre is connected to a computer you can use the AudioFuse Control Center to switch between USB and ADAT modes.

USB mode

When the AudioFuse 8Pre is the master clock (Internal clock) and also in USB mode:

  • if you're connected to a MacOS computer you must use the Audio MIDI Setup application to change the clock sample rate

  • if you're connected to a Windows PC you can either use the AFCC or your audio application if it allows this setting.

In this mode:
The clock setting cannot be changed from the front panel.
The sample rate cannot be changed from the front panel.


ADAT mode

Once in ADAT mode, the clock rate can only be changed from the front panel when the AudioFuse 8Pre is in ADAT mode, and when it is using its internal clock (i.e., Sync = INT).

As the Clock button is pressed, the clock rate LEDs will indicate which clock rate has been selected.

If Sync is set to ADAT or WORD the clock rate must be changed from the external device.

The clock rate LEDs will indicate which clock rate is being received, and the LOCK LED will confirm that the two devices are synchronized.

Method 1: Direct USB connections

The advantage of this arrangement is that both devices can be controlled by the computer using the AFCC.
They will be seen by the computer as a single USB audio interface in most cases.

  • Connect the number of optical cables required by the clock rate

    ◦ 44.1k and 48k use ADAT In/Out #1, so you'll need a pair of cables
    ◦ 88.2k and 96k use ADAT In/Out #1 and ADAT In/Out #2, and require two sets of cables

  • Connect both AudioFuse 8Pre units to the computer via USB

  • Put one AudioFuse 8Pre into USB mode and the other AudioFuse 8Pre into ADAT mode.

  • Select Sync = ADAT for the AudioFuse 8Pre unit that is in ADAT mode.


Method 2: Single USB connection + ADAT

This configuration is ideal for operating systems that will not recognize an aggregate device, such as a Windows PC using the ASIO driver or if you are running short on USB input.

  • Connect the number of optical cables required by the clock rate

    ◦ 44.1k and 48k use ADAT In/Out #1, so you'll need a pair of cables
    ◦ 88.2k and 96k use ADAT In/Out #1 and ADAT In/Out #2, and require two sets of cables

  • Connect the first AudioFuse 8Pre to the computer via USB (Do not connect the second AudioFuse 8Pre to the computer)

  • The first AudioFuse 8Pre must be in USB mode and the second must be in ADAT mode.

  • Change the Sync source of the second AudioFuse 8Pre to ADAT.

Connect two AudioFuse 8Pre with Word Clock

  • Connect a BNC cable from the Master device Word Clock Out to the Slave device Word Clock In

  • On the slave device front panel, set the Sync to WORD.

  • From the AudioFuse Control Center, set the Wordclock Impedance to 75 Ohm.

  • Change the Sync source of the second AudioFuse 8Pre to ADAT.

Connect Three AudioFuse 8Pre with Word Clock

  • Connect a BNC cable from the Master device Word Clock Out to the first Slave device Word Clock In

  • On the slave device front panel, set the Sync to WORD

  • From the AudioFuse Control Center:
    ◦ Set the Wordclock Impedance to Hi-Z
    ◦ Set its Pass Thru to ON

  • Connect a BNC cable from the fist Slave device Word Clock Out to the second Slave device Word Clock In
  • From the AudioFuse Control Center:
    ◦ Set the Wordclock Impedance to 75 Ohm
