PART II: Tutorial

This tutorial is designed for the first time user of the Model 3000S. It requires that the default settings

conform with the "factory default settings". To reset the unit to the factory default settings press and hold

the push button labeled EXIT while powering up the unit.

A SOURCE is defined as an output device generating the digital audio data stream, and a

DESTINATION is defined as the device receiving the data.

For most applications, the Model 3000S input is connected to the output of a source. The Model 3000S

acts as a "stand alone" source when used as a test tone generator with an internal crystal based

oscillator setting the output sample rate.

The Model 3000S output always drives destination device inputs, at an output sample rate determined

by the Main Screen Mode settings.

Before proceeding further, we recommend reading the introduction of the Operating Instructions in this

manual. The following sections assume familiarity with operation of the push button switches.

Connect one or two source devices to the rear panel connectors marked AES/EBU INPUT XLR plug

and/or S/PDIF INPUT RCA plug (these connections are not needed when the Model 3000S is operated

as a "stand alone" test tone generator).

Connect the Model 3000S to its destination devices via the output plugs marked as AES/EBU OUTPUT,

and S/PDIF OUTPUT. You may use either or both of the outputs simultaneously.

An external Sync source may be connected to the AES SYNC INPUT connector.

Apply AC power to the Model 3000S, and to your sources and destination devices. The Model 3000S

displays its ROM version for 5 seconds (referring to its internal software version). The user may choose

to bypass the 5 second wait by pressing any of the front panel buttons.

The first screen is the main screen. The top line of the LCD (liquid crystal display) shows data

associated with the selected input connector. The choice of input selected is indicated by an LED

located to the left of the LCD display (AES/EBU or S/PDIF LEDs). The SYNC LOCK LED indicates the

lock condition of the sync input, if the selected mode requires sync. The RCV LOCK LED indicates that

the MODEL 3000S has detected a digital audio signal at its input and locked to it.

Press the CURSOR UP button once to view the input selection screen. You may view the present input

selection at the screen and the LED simultaneously. Press the ENTER button to introduce a screen

cursor (on the word AES/EBU or S/PDIF). Press the CURSOR DOWN or CURSOR UP button several

times to view the input selection process.

Press the EXIT button to remove the cursor. Press EXIT again to return to the main screen. (Pressing

EXIT from a screen with no cursor quickly returns you to the main screen. You may choose to use the

CURSOR UP/DOWN buttons to scroll through the screens). You may now view incoming parameters

associated with the incoming data from the selected input on the top display line indicated by "IN:". The

first word (CNS or PRO) indicates Consumer or Professional data format, followed by a number 32, 44

or 48 indicating the frequency coding embedded in the data stream. The next five digit number displays

LE3000S
