First measure the average length (D) of the sound zone in (actual) inches.
Then set the FADER value using the following formula:
FADER = D x R
--------
3.52
where R = Ratio of Scale (i.e., 87.1 for HO, 160 for N Scale, etc.)
You can use the following simplified formulas for each of the popular scales:
For Z Scale, FADER = D x 62.5
For N Scale, FADER = D x 45.5
For HO Scale, FADER = D x 24.8
For S Scale, FADER = D x 18.2
For O Scale, FADER = D x 13.6
The third method simply picks a distance (D), in inches, from the edge of
the sound zone where you want the sound to reach maximum volume.
Again, the system will automatically compensate for faster or slower moving
locomotives. Once you have determined D, use the following formula to find
the correct FADER value.
FADER = D x R
--------
1.76
where R = Ratio of Scale (i.e., 87.1 for HO, 160 for N Scale, etc.)
You can use the following simplified formulas for each of the popular scales:
For Z Scale, FADER = D x 125
For N Scale, FADER = D x 90.9
For HO Scale, FADER = D x 49.6
For S Scale, FADER = D x 36.4
For O Scale, FADER = D x 27.2
1. From System Monitor mode, push the control knob to display
ROUNDHOUSE. Turn the control knob until the display reads AUDIO.
Push the control knob to select the Audio menu.
2. The first display will read SND ZONE: 1. Push the control knob to select
and turn the control knob until it reads FADER: 0001. Set the Fader rate
for this sound zone.
3. Turn the control knob until the display reads BACK. Select this by
pushing the control knob. Now turn the control knob clockwise until the
display reads SND ZONE: 2. Repeat this process, setting the Fade rate
for each sound zone.
Ambient Effects
The AUDIO menu offers echo and reverberation options that you can use to
produce ambient effects within a given sound zone. For example, you might
use echo for realistic sound within a canyon or reverb for a tunnel.
