clank volume. Either CV can be set between 0 and 255. See Audio Mixer for
more details. If you are installing the Tsunami in a geared engine, you may
wish to disable the rod clank by setting CV 135 down to zero.
If you are using the DDE feature, remember that these CVs set the baseline
(i.e., zero-load ) volume level so take care not to set either volume level too
high or too low as it will limit the range over which the DDE module can make
adjustments. For example, if you maximize the exhaust chuff volume with
CV 131, the DDE will not be able to increase it further when the engine is
subjected to a greater load.
Airpump Control
There are two CVs to adjust the Airpump:
CV 112, Airpump Select Register
CV 132, Airpump Volume
Airpump Select
Most small and medium sized locomotives had a single airpump while heavy
and articulated steam engines often had two airpumps. To select between
single or dual airpumps, use Table L to find the proper setting for CV 112 in
conjunction with the exhaust control mode (see previous section) you would
like to use.
If you are modeling a locomotive that did not have an airpump at all, you can
turn the airpump off by setting the volume down to zero.
Airpump Volume
CV 132 sets the Airpump volume and may be set between 0 and 255. See
Audio Mixer for more details.
Dynamo Configuration
The Dynamo volume is set using CV 133 which may be set to any value
between 0 and 255 as discussed under Audio Mixer.
By default, Tsunami Steam decoders map the Dynamo sound control to the
Headlight and Backup Light functions. See Function Mapping for information
on how to change the Dynamo control over to another function. If you prefer
to turn the Dynamo off altogether, you must also reconfigure the headlight
and backup light to use a different effect (see Lighting Effects) as the Dyno-
Light lighting effect will not turn on when the Dynamo sound is disabled.
