如何将对讲机连接到放大器或有源扬声器?

介绍

概述

在某些应用环境中,对讲机的内置扬声器可能无法提供足够的音量。在这种情况下,可以添加外部功放或有源音箱。由于接线点因型号而异,本指南说明如何将不同对讲设备连接到外部功放或有源音箱。

支持型号

Bi12, BHP-S0S16, BHP-S0S16V, BK-DAB-PA2, BK-DAB-PA2S, BK-DAB-PA3, BHP-SOS10, BHP-SOS10V, BHP-SOS10SD, BHP-SOS11V, BHP-SOS11V2

所需设备与工具

1. 一台 Becke 对讲设备(本文以 BHP-S0S16V 为例)、一台 PoE 交换机或 DC 电源,以及一个有源音箱。将设备连接到交换机。

2. 一台用于设置与测试的电脑。将电脑连接到同一台交换机,并确保电脑与设备之间可以通过网络通信。

设备与电脑连接图

将 BHP-S0S16V 连接到交换机,并将电脑连接到同一台交换机。确保电脑与设备之间的网络是可达的。典型的连接示例如图 1 所示。

对讲机连接方法

不同对讲机型号使用不同的外部有源音箱接线点。以下各节说明每个型号组别的连接方法。

Bi12 连接至有源音箱

对于 Bi12,请使用 Audio_out 接口连接有源音箱,如图 2 所示。左侧的端子是音频信号输出,应通过接线端子连接到有源音箱的音频输入线。右侧的端子是 GND,应连接到有源音箱的公共接地端子。

BK-DAB-PA2 连接至有源音箱

对于 BK-DAB-PA2,有源音箱的接线位置如图 7 所示。HEADSET 接口用作音箱音频信号输出。

HEADSET 输出为差分式。如果连接的设备使用差分输入,请连接 HEADSET+HEADSET- 和电源 GND (POWER-)。如果连接的设备使用单端输入,请连接 HEADSET+ 和电源 GND (POWER-)

BK-DAB-PA2 连接至有源音箱

BK-DAB-PA2S 连接至有源音箱

对于 BK-DAB-PA2S,请使用 Line out 接口连接有源音箱,如图 8 所示。右侧的端子是音频信号输出,应通过接线端子连接到有源音箱的音频输入线。左侧的端子是 GND,应连接到有源音箱的公共接地端子。

BK-DAB-PA2S 连接至有源音箱

                                                                                                      图 8. BK-DAB-PA2S 连接至有源音箱

BK-DAB-PA3 连接至有源音箱

对于 BK-DAB-PA3,请使用 Line out 接口连接有源音箱,如图 9 所示。音频信号输出应通过接线端子连接到有源音箱的音频输入线,而 GND 应连接到有源音箱的公共接地端子。

BK-DAB-PA3 连接至有源音箱

                                                                                                  图 9. BK-DAB-PA3 连接至有源音箱
