最后,要认识到即使PR 15D是一架强有力的高输出设备,最终还是有其局限性,它可能还是需要额外的有 源设备(或重低音扬声器)来提供足够的音响输出或覆盖。在这种情况下,试试看将混音器的电平调低一点 会不会解决问题。

如果在检查了所有所列项目和任何您能想得到可以安全检查的项目之后,系统仍然存在问题,仔细记下所 有情况,咨询您的Peavey 经销商。

保养和维护

您的PR 15D是一台稳定耐久的产品,如果适当维护,能可靠地使用许多年。使用常识,阅读安全须知,避 免危险操作状况。

开展任何养护工作之前,必须将设备从AC电源上断开。请务必使用专业的维修人员。

阳光/

避免长久暴露在直线阳光下,这会造成设备过热和热关机。过分热的操作状况也可能导致热关机。

不要储藏在过热、过冷或湿度过高的状态下。使用前一定要让设备回到室温温度。

清洁

永远不要在插电或开机时清洁PR 15D。当设备完全从AC电源上断开后,使用干布抹去尘土。千万不要在 PR 15D上使用强溶剂,它们可能损坏音箱。不要让任何液体滴进PR 15D

润色上光

要增加外观色泽和保护涂层,仅在塑料箱体表面用手套涂上Armor-All®一类的塑料面保护剂。要注意处理 过后的音箱会很滑手,用干燥、不掉毛的抹布好好地擦一下,减轻这种状况。

检查固定件

经过头几个月的使用后,要检查PR15D的固件是否紧密,包括后面板的螺丝及固定隔音板和后箱体的螺 丝,并在以后定期检查。此设备振动激烈,随着使用会将它们震松。

结构及工程规格

此有源扬声器的频率响应在47 Hz20 kHz。在1米距离,输出能力完全驱动下测量,其音乐源无音响失真 的峰值SPL(声压级)应达到120分贝。此系统应使用一台15"重型低音扬声器和一台RX14压缩驱动高频扬声 器。其标称辐射形态应为水平90°和垂直40°

此有源二分频扩声扬声器系统在后面板上应有一组中阻抗输入连接器,包括一个母式XLR1/4" TRS组合 话筒插头,和二个1/4"话筒插头。靠近每个输入插口各有一个音量控制。其母式XLR1/4" TRS组合话筒 插头有一个增益调整衰减器,支持线路电平输入信号和麦克风电平输入信号之间的切换。

该系统功放应有未过滤频率响应10Hz30kHz,额定功率下偏离不超过+0-1dB,阻尼系数在1 kHz, 8 欧 姆时大于100,哼声和噪声低于额定功率90 dB以上,THD(总谐波失真)IMD(互调失真)低于0.1%。该低音 放大器在8欧姆标称负载时应能胜任150瓦,高频扬声器功放在8欧姆负载下应有50瓦的输出,两者都应包 含各自的DDT压缩。

交错极点三阶斜率线路电平分频器应在2 kHz将输入信号电子分频至高频和低频。低频经过处理,应提供 低音提升,重低音滤波和总体响应波形,而高频则应为恒指向性号角均衡波形和响应波形平衡提供补偿。

箱体结构应是注塑聚丙烯,1/4"的标称厚度,UL防火等级,内装加强肋架。把手应有一个模塑在顶部后 沿,低音扬声器的两边也各有一个。
