Options Screens
Control of the two OPTIONS screens is done in the same manner as previously stated (find the screen
with the CURSOR buttons, ENTER to introduce and move a cursor, CURSOR UP/DOWN for setting
selection and EXIT for removing a cursor). These screens allow the user to configure the Model 3000S
operation as described below:
CLIP AUTO-MAX ON/OFF: When set to ON, the BAR-GRAPH display serves to warn the user when the
audio has reached a peak (maximum or minimum code value). A peak condition will turn the MAX LED
on and start the 0 dB LED blinking (for the corresponding channel). Pressing any button will turn these
LEDs off until the next peak is detected.
DITHER ON/OFF: Use of Acoustic Bit Correction, the built-in noise shaper plus dither is recommended
for truncating from a longer word to a shorter one. See Appendix I for more details of Acoustic Bit
Correction.
READ LEFT/RIGHT CSBITS: When set to LEFT, the Model 3000S reads the digital audio information
from the left channel (this is likely to cover most source material). The user may select the right channel.
Power-Up Preset
The Preset screen starts with "STORE RAM PRESET". You may store the present settings of the Model
3000S into the RAM preset (press GO) or exit the screen.
Test Tones
To generate a test tone, scroll to the test tone screen and set the frequency, amplitude and destination
(left, right or both). To change the frequency or amplitude by large increments, hold down the CURSOR
UP or CURSOR DOWN buttons. For small increments, press the CURSOR UP/DOWN repeatedly.
Press GO to start the tone. You may change settings while the tone is generated. To stop the tone
press EXIT twice (returning to the communications screen).
Note: internal tone generation consists of 24 bits of resolution. The word length at the output is subject
to truncation and dither settings. CNS word length is always 16 bits.
