不要選擇失速電流消耗超過解碼器額定值
以下程序可用于確定機(jī)車的失速電流：1.將機(jī)車放置在一段軌道上，該軌道由常規(guī)直流電源組供電，N、HO、s和O刻度設(shè)置為12伏，G刻度設(shè)置為16伏。2.如圖1所示，將直流電流表與其中一條軌道饋線串聯(lián)連接。如果您的電源組有內(nèi)置儀表，則可將其用于此目的。3.握住機(jī)車以防止其脫離時，將電源組調(diào)至全開狀態(tài)。4.通過將機(jī)車?yán)卫瓮迫胲壍阑蜃プ★w輪或傳動軸來停止電機(jī)轉(zhuǎn)動。5.為了確保最準(zhǔn)確的電流測量，請確保在此測試期間，電源組電壓保持在12伏（G刻度為16伏）。6.測量電機(jī)失速時機(jī)車的電流。這是失速電流，必須小于解碼器的額定容量
揚(yáng)聲器磁鐵
正確的揚(yáng)聲器外殼的使用再怎么強(qiáng)調(diào)也不為過，不使用揚(yáng)聲器外殼幾乎總是導(dǎo)致音質(zhì)差的原因。幸運(yùn)的是，大多數(shù)蒸汽機(jī)都有一個外殼，只要稍加努力，外殼本身就變成了一個很棒的揚(yáng)聲器外殼。揚(yáng)聲器可以面朝上穿過煤倉，也可以面朝下穿過地板。無論哪種方式都能產(chǎn)生同樣好的聲音。您還需要盡可能使用最大的揚(yáng)聲器來獲得最佳的低音響應(yīng)。更大直徑的揚(yáng)聲器可以在寬度上進(jìn)行修剪，以便它們能夠安裝在柔嫩的外殼內(nèi)。通過構(gòu)建內(nèi)部擋板，它們也可以以一定角度安裝，盡管這會影響DSD模塊的可用空間，但最大的投標(biāo)除外。在小型投標(biāo)中，揚(yáng)聲器應(yīng)安裝在煤倉區(qū)域的前方，那里有較高的墻壁覆蓋揚(yáng)聲器磁鐵。
Do not select stall current consumption exceeding decoder rating
The following procedures can be used to determine the stall current of the locomotive: 1. Place the locomotive on a track that is powered by a conventional DC power pack, with N, HO, s, and O scales set to 12 volts and G scales set to 16 volts. 2. As shown in Figure 1, connect the DC ammeter in series with one of the track feeders. If your power pack has built-in instrumentation, you can use it for this purpose. 3. When holding the locomotive to prevent it from separating, turn the power pack to the fully open state. 4. Stop the motor rotation by pushing the locomotive firmly into the track or grasping the flywheel or drive shaft. 5. To ensure the most accurate current measurement, please ensure that the power pack voltage is kept at 12V (G scale is 16V) during this test. 6. Measure the locomotive current when the motor stalls. This is the stall current, which must be less than the rated capacity of the decoder
Speaker magnet
The correct use of the speaker shell cannot be overemphasized. Without the speaker shell, the poor sound quality is almost always caused. Fortunately, most steam engines have a shell. With a little effort, the shell itself becomes a great speaker shell. The speaker can be face up through the coal bunker or face down through the floor. Either way can produce the same good sound. You also need to use the largest possible speaker for the best bass response. Loudspeakers with larger diameters can be trimmed in width so that they can be installed in soft enclosures. They can also be installed at an angle by building internal baffles, although this will affect the available space of DSD modules, except for the largest bids. In small tenders, loudspeakers should be installed in front of the bunker area, where a high wall covers the speaker magnet.
