te:
As of the date of publication of this User Manual, there are no Atlas models of prototype diesel locomotives that
have two Prime Movers. Hence, CV52.11 is not currently used in any Atlas Gold Series locomotives.
To change the overall volume of one of the sounds listed in Table 8, perform the following operations:
•
Set CV49 to the Primary Index (second or green column) for the individual sound whose volume you wish
to change by using the value specified in the CV49 column in the table above.
•
Enter the desired Volume level in CV52 to one of the values listed in the third or blue column as follows:
“0” = No sound, “1 – 15” sets volume from the lowest level at “1” to the highest at “15”, with the volume
levels changing in 2 dB increments.
No
te:
Normally, the default volume level for each type of sound is 11.
Example
: To set the overall volume of PrimeMover1 to 0, do the following programming
•
Set CV49 to 10 to select PrimeMover1.
•
Set CV52 to 0 to set the new PrimeMover1 volume.
If you do this programming in
Ops Mode
(recommended) you will immediately hear the effect of the new volume you
have programmed.
4.2.9.2 Changing Volumes of Prime Mover Sound Components (CV127.PI.SI) – Version 9
only
QSI Version 9 firmware for the Quantum Titan sound decoder allows the user to change the volume of not only the
prime mover, but also some of the components making up this overall sound. The sound components whose volumes
may be set individually are:
•
Diesel Prime Mover volume at three different RPM levels (idle, mid-RPM, max-RPM),
•
Exhaust volume at three different RPM levels,
•
Labored exhaust volume at three different RPM levels,
•
Rod knock volume at three different RPM levels,
•
Generator volume at two different RPM levels (idle and max-RPM),
•
Turbocharger volume at two different RPM levels (idle and max-RPM).
This feature will probably be of most interest to intermediate to advanced users, especially to those who are also
railfans. So that you can hear quickly the results of a CV value change, it is strongly recommended that you do all
programing on the main line (
Operations Mode
) rather than on the program track (
Service Mode
). Furthermore,
although this programming may be done with a standard DCC system, it is easier to use (an up-to-date version of) the
Quantum CV Manager
[bundled with the QSI Quantum Programmer and sold by QSI Solutions].
As shown in Table 9 below, a doubly-indexed Configuration Variable (CV127.PI.SI) is used to set the volumes of the
individual sound components.
