User manual DALLEE ELECTRONICS ELECTRIC SOUND VERSION 3

[. . . ] IN LOCOMOTIVE ELECTRIC SOUND SYSTEM for various track power by DCv3 rev8 CAUTION: This device can be damaged by static discharge. Please exercise care during installation to avoid this possibility. Discharge yourself to an electrical ground (outlet cover screw) before removing this device from its anti-static bag. Please read instruction sheet completely before attempting to install and operate this product. [. . . ] If you have a HUM or other static noise in the audio output it is because this power is not filtered enough. Add a large electrolytic capacitor (470 mfd @ 25 vDC or larger) across this DC supplies output (when power is off). Make sure you observe the polarity markings of the capacitor ! Gray Gray S4 Red S3 S2 524 SPST switch. Switch shown in the OFF position. Drawn as a spst. Red S1 Stationary AC power installation using track power for notch setting. speaker You can also add an auxillary Amplifier, see pages 8, 9, and 10. Black Switch key: S1 - Horn (momentary) S2 - Bell S3 - Force Cooling Fans S4 - Main sounds off White Red Gray Right Rail Left Rail either rail may be used. Right / Left only used for reference. + ­ ON / OFF switch Red Gray + extra filter capacitor observe polarity ! 524 SPST switch. Switch shown in the OFF position. Drawn as a spst. fixed AC power 10 - 18 vAC you MUST NOT EXCEED 18 volts AC. DC voltage created from AC is 1. 414 X vAC, 18vAC = 25 vDC !A HUM in the audio output is because the DC power is not filtered enough. Add a large electrolytic capacitor (470 mfd @ 25 vDC or larger) across the DC output as shown (when power is off). Make sure you observe the polarity markings of the capacitor ! Gray Gray S2 Red S4 S3 Red S1 5 speaker DCC receiver installation using motor power for Main Sound activation and function control for HORN, BELL, Manual Cooling Fans, Main Sounds ON / OFF Black M White Red Gray Connect motor if present DCC track power input receiver motor leads (Orange / Gray is standard practice). If you are using a seperate receiver merely connect the motor leads to pins 2 (black) and 3 (white) of J3. The sound system presents a load of 480 to 980 ohms (depends on speed set control setting). Make sure that your receiver is operating in the same step mode as the transmitter !! Gray No connection is required to J2. All of the sound system power is supplied from the track via J1. Gray S4 S3 S2 S1 Function key: S1 - Horn (momentary) S2 - Bell S3 - Force Cooling Fans S4 - Main sounds off Connect S1 thru S4 to function control desired. You do not need to connect functions you do not intend on using. S1 - HORN function. Connect to desired function output of module. Some DCC systems offer a momentary type function. It is best to use what the system you are using suggests. Digitrax - use F2 function Wangro - use F3 function Red Red S2 - BELL function. Suggest function as set by DCC system you are using. Digitrax - use F1 function Wangro - use F2 function S2 -> S4 - function. When using an extra receiver you can use either Forward or Reverse lamp function output of module. [. . . ] As shown above, the body shell is used as the backside of the baffle The more speakers, the better the sound (especially when using small speakers as in model locomotives. Four speakers make an ideal configuration. alternative lighting you might also want to consider installing our Adjustable Regulated Lighting board. The RL-ADJ (item 379) comes with four 2. 7v lamps (item 383) but is capable of driving eight lamps, as shown. You can set the intensity desired (1. 25 - 6. 2 volts). [. . . ]
