DALLEE ELECTRONICS Speakers Manual 

diesel locomotives that are designed to operate with conventional DC track power, digital (DCC) or other types of command control systems including radio with either track or battery power, also as a stationary sound unit. Because of its dimensions (2.7" x 0.9" x a ...

permit a higher volume without damage to the individual speakers. A tube with a speaker at each end or a speaker in a doorway at each end of a body shell is an excellent approach. A four speaker approach will yield the highest volume while still maintaining the 8 ...

Battery power - must not exceed 24 volts DC. Use one 9 volt battery or a string of 6 AA or AAA batteries (24 volt DC maximum input). Life depends on volume setting and speaker impedance. Typical operation of most sound systems for one good 9 volt batteries is about 8 hours, AA or ...

Chokes: Item 702 - 1.5 ampere loads Item 703 - 5.0 ampere loads wires with a " " ARE a connection! wires crossing over (without a " ") DO NOT CONNECT! This diagram allows for the use of rechargeable batteries. When track voltage exceeds battery voltage, the sound system will operate from track voltage and ...

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 th ...

problem with any other type, we have not verified it. The sound unit has been designed and operated with WANGRO, DIGITRAX, and LENZ systems to verify DCC operation and compatability. ADD ...

function control for HORN, BELL, Full RPM, Main Sounds ON / OFF Connect S1 thru S4 to function control desired. You do not need to connect functions you do not intend on using. If using as a stationary unit or in a larger locomotive, you can always add one of our 11 or 22 wa ...

switches for HORN, BELL, Full RPM, Main Sounds ON / OFF DC battery power input. Input voltage of 7 to 24 volts DC. Absoulute maximum input is 35 volts DC! If the battery supply is not the same as the receiver supply, connect the gray "-" wire to the "-" of the receiver supp ...

Aristocraft relay board (ART-5490) for HORN, BELL, Full RPM, Main Sounds ON / OFF DC power output. This is the rectified power from the sound system. When operating on DC track power, since the polarity is unknown, the input power must be connected to ...
