around 70 while the exhaust is comparable to the whistle so it would be set
to a value around 200. To adjust the sound level for a particular effect, set the
corresponding volume to a value between 0 (mute) and 255 (100% volume).
In the EDIT LOCO submenu of the ROUNDHOUSE select the road number
you were just editing and turn the knob to the right. You will see the master
volume first and can begin setting up each of the volume settings as listed on
the table below. The description in the table is identical to how they appear
on your SurroundTraxx display. For example WH MIX : 000 is the whistle
volume level.

Note: Names inside ( ) indicate Diesel sound effects.
A certain level of prudence is needed when adjusting the mixer levels to
avoid the condition known as ‘clipping’ or ‘limiting’, which occurs when the
sum of two or more signals exceeds the capacity of the output channel. As its
name implies, clipping results in the lopping off of the sound signal peaks and
manifests itself as distortion accompanied with a level of clicking or popping
sounds. The System Monitor mode helps to identify clipping as it occurs.
To avoid a clipping condition, consider which sounds are likely to be played at
the same time and take care to ensure that their corresponding mixer levels
are not set too high.
You may wish to make the FX Bus Mixer adjustments at the same time, since
they affect the same individual sound effects and are located adjacent to one
another in the menu - see below.
FX Bus Mixer Parameters
The FX Bus Mixer Parameters dictate the level sent to the echo/reverb sound
effect feature for each of the effects in the table that follows. When adjusting
these parameters, use care to keep the various levels realistic in relation
to each other. For example, you would generally want the echo and reverb
effects to affect a whistle more than a bell.
