As the change is selected, the check mark will follow. Note that in elements where PD (Power Down) is
an option, the element can be set up for a specific gain and be powered down also. In this case, the
element is just powered down. Ignore the gain indication. [Note, The Feedthru path is not illustrated on
the screen. It is selected as "MIC" at the ANA OUT Mux.]
The controls to the two on-chip mixers operate slightly different. The SUM 1 mixer inputs are called
MUTE INP and S1S ON and the SUM 2 mixer inputs are called FILT ON and MUTE ANA. Click on these
to select red for OFF and green for ON.
Most changes do NOT take place immediately. The ‘UPDATE” indicator in the upper right corner of the
display will light red to indicate that a change has been indicated but not executed. Click on the UPDATE
button beneath the "UPDATE" indicator to cause all the indicated changes to be made at the same time.
There are two exceptions to the update sequence. If the volume control is changed, it updates
immediately without the need to click on UPDATE. Also, if a Standard Path is selected, it also causes an
immediate change in all the paths.
Standard Paths are very easy to set up. Simply program the chip into a desired state making sure that
the update button (if red) has been clicked on. Then select ADD PATH, name the path as desired and
click on OK. The new path will be added to the list. Paths may be deleted in a similar manner.
Record, Playback, Message Cueing (MC) and Power Down (PD) are directly and immediately controlled
by the buttons in the lower right side of the screen. PD is either red or green to indicate the overall power
status of the chip. Green indicates the chip is powered up.
The bottom center button in this area is the Ignore Address/Use Address select. If IGNORE ADDR is
selected, the chip will begin the “next” operation where the previous operation ended. If USE ADDRESS
is selected, the address indicated in the white block immediately to the left of this button will be used. An
address may be directly entered in this block after positioning the cursor.
