Default Clock

Use the Default Clock to change the Emulator’s output sample rate (clock rate) to either 44.1 kHz or 48 kHz. This function sets the output rate of the entire machine (analog as well as digital outputs). Digital audio recorders automatically record at the clock rate of the source, so set this control at 48 kHz to record into a DAT recorder.

Ultra Series. This function is tied to analog sampling on the Ultra series Emulators. There are four analog sample rates (22.05 kHz, 24 kHz, 44.1 kHz, 48 kHz), but depending on this setting only two are selectable at a time.

Default clock = 44.1 kHz (22.05 kHz & 44.1 kHz)

Default clock = 48 kHz (24 kHz & 48 kHz)

Change the default clock rate if the analog sample rate you want is not available in the Sample Manage module

v To Change the Default Clock Rate:

1.Press the Master button. The LED illuminates and the Memory Statistics screen appears.

2.Press the Setup function key (F3). Another row of function keys appears.

3.Press the In/Out function key (F2). The Input/Output screen appears.

4.Move the cursor to the Default clock field using the cursor buttons or by pressing the F4 key.

5.Set the Default clock rate using the Data Entry Control, or INC/DEC buttons.

6.Press the Exit button twice to return to the Memory Statistics screen.

Input/Output

Note: If an external word clock is not physically connected, EOS defaults to its internal clock (even though the display is set to an external source).

Word Clock In

This Ultra function selects the Word Clock source. The Word Clock is the master time-base reference for the Emulator audio engine. Normally Word Clock In will be set to Internal to use the internal crystal-based reference. When transferring digital data, the different pieces of gear need to be synchronized to the same master clock. The BNC connector on the rear panel (optional on some models) allows the Emulator to synchronize with an external clock source (a house sync generator or word clock out from another piece of digital gear).

•Internal .Uses the Emulator’s ultra-stable crystal reference oscillator.

•BNC........Uses the word clock received at the rear panel BNC Word

Clock In connector.

• AES ........ Uses the word clock provided by the rear panel AES digital input connector.

•ADAT .....Uses the Word Clock embedded in the ADAT optical data. v To Set the Word Clock Source:

1.Press the Master button. The LED illuminates and the Memory Statistics screen appears.

2.Press the Setup function key (F3). Another row of function keys appears.

3.Press the In/Out function key (F2). The Input/Output screen appears.

4.Change the Word Clock In status. Move the cursor to Word Clock In using the cursor buttons or by pressing the F6 function key. Choose the Word Clock source using the Data Entry Control, or INC/DEC buttons.

5.Press the Exit button to return to the Memory Statistics screen.

WC Phase In/Out

This Ultra function allows you to adjust the phase relationship between input and output sample clocking in order to compensate for clock phase delays in other equipment or when word clock is daisy-chained. On EOS machines, a setting of 0.00 degrees means that the word clock in phase is exactly equal to the word clock out. If you are having trouble synchronizing to other equipment, try adjusting the appropriate word clock phase control to remedy the problem.

WC Phase In. Adjusts the phase relationship between the input clock (BNC, AES, or ADAT) and the digital output embedded data clock.

WC Phase Out. Adjusts the phase relationship between the input clock (BNC, AES, or ADAT) and the Emulator Word Clock output.
