the actual data rate measured by the internal counter of the Model 3000S. The last indication (on the
right side of the top line) indicates the emphasis type coding.
Bar-Graph
View the BAR-GRAPH LEDs while your source is playing audio data. Observing the peak-hold action of
the far right LED will help avoid clipping of the audio.
Press the CURSOR UP button to change screens. The screen starting with the word "FINE" is used for
adjusting DISPLAY MODE, METER RANGE, LCD DISPLAY brightness and METER intensity.
Press ENTER to introduce a cursor for FINE: OFF/ON. Select mode using the CURSOR UP/DOWN
buttons. With FINE mode ON, the number to the right (the next cursor position) sets the reference level
in 1 dB steps from -10 to -20 dB. The LED corresponding to the reference level will light continuously on
the bar graph and the level will be displayed in 0.2 dB increments for accurate calibration.
Press ENTER a third time to move the cursor to METER position, then set desired meter range from -00
to -90. Pressing ENTER again, moves cursor to L or H for LED display brightness. Set the desired
intensity using the CURSOR UP/DOWN buttons.
Press ENTER to move the cursor to DISPLAY position, then set for the desired contrast by using the
CURSOR UP/DOWN buttons.
Press ENTER several times, observing how the cursor location moves on the screen. You may "park"
the cursor at any location and edit the settings by using the CURSOR UP/DOWN buttons. Press EXIT to
remove the cursor. This sequence is applicable to all of the screens.
Output Format and Sample Rate Conversion
Find the main screen either by scrolling to it or by pressing EXIT twice. Press the CURSOR UP (or
CURSOR DOWN) button for several seconds to quickly scroll through the screens (This quick scrolling
action will be particularly useful under test tone generator programming of frequency and amplitude).
Press EXIT to return to the main screen.
Press ENTER to introduce a cursor. Set the output data format to CNS (consumer format).
Move the cursor to output frequency indicator and set it as desired.
Move the cursor to the next location. Scroll through the choices. BYPASS setting provides for the output
data transfer rate to be synchronized with the input rate (direct transfer). The other choices change the
sample rate of the output to an internal crystal operation or external sync operation, as well as the 24
BIT ENCODE and 24 BIT DECODE modes, for use with 16-bit 96 kHz digital recorders.
After setting all of the output parameters, press the GO button to activate. (You may press GO before or
after removing the screen cursor with the EXIT button). If GO is not pressed within five seconds of
changing a parameter, the parameters revert to their programmed settings.
Press EXIT to remove the cursor. Press the CURSOR DOWN once to observe further input and output
settings associated with the CNS (consumer output format) selected in the communications screen. This
screen is aimed at controlling COPY PROTECTION AND GENERATION settings. Use the ENTER and
CURSOR buttons to become familiar with these screen settings.
In PRO mode you can change the WORD LENGTH indication. Note that a change in word length
indication is coupled with an actual change in the digital audio data word length. This can be used for
truncation of a long incoming word (up to 24 bits) to a shorter word length. NI (word length not indicated)
is interpreted as 20 bit output word length. Truncation may be done with or without the ACOUSTIC BIT
CORRECTION as explained in Part I.
