Shure舒尔515SBGX、515SBG-18X和515SBG-18XF是一款专为语音录制、语言教学实验室、广播及广播站通信设计的低阻抗动态麦克风。它们的特点在于其优化的频率响应和单向(心形)拾音模式,使得它们在语言教学、电话调度、电视、电影录音棚以及现场直播中表现出色。 这些型号的麦克风特别适合需要清晰声音传播的应用场景,如公告、叙述和寻呼系统。它们采用钕磁铁,提高了信号与噪音比,确保在高噪声环境中也能保持清晰度。内置的防震技术在转接头处有效降低了操作时的机械噪音,提供安静的使用体验。 麦克风主体由坚固的铸铁防护网和把手组成,确保耐用性,即使在长期使用或在有震动的环境中也能够保持稳定性能。特别值得一提的是,它们均配备了内置的按压通话(Push-to-Talk, PTT)功能,这个按钮不仅控制麦克风电路,还能够切换到对讲或遥控电路,方便用户在不同的应用场景下进行操作。 所有这三个型号的麦克风都配备了一根四芯线缆,其中两芯是屏蔽的,提供了良好的电磁干扰防护。它们的总长度为45.7英寸,这意味着即使在较长距离的连接下,依然能保持低阻抗特性,确保音质不受电缆长度影响。 Shure舒尔515SBGX系列麦克风以其专业级的性能、易于使用的特性以及出色的适应性,成为音频工程师、播音员和录音工作室的理想选择。无论是固定安装还是手持使用,都能提供稳定且清晰的声音记录和传输。

General Description
515SBGX
515SBG-18X
The Shure Models 515SBGX, 515SBG-18X, and 515SBG-18XF microphones
are low-impedance dynamic microphones designed to be mounted on flexible
goosenecks or fixed pips. Optimized frequency response and a unidirectional
(cardioid) pickup pattern makes them ideal for language labs, paging appli-
cations, and base station communications. They are also recommended for
use as talkback or cuing microphones in TV, film, and recording studios.
Because of their low impedance, these microphones retain their level and
response characteristics even when long lengths of cable are used.
All three models are supplied with a push-to-talk button and a four-conductor
cable (two conductors shielded).
Features
• Frequency response optimized for announcing, narration, and paging
applications
• Cardioid pickup pattern symmetrical about axis
• Neodymium magnet for high signal-to-noise ratio
• Shock-mounted cartridge for quiet operation and low stand/handling
noise
• Tough diecast locking grille and handle
• Built-in push-to-talk button controls microphone circuit and relay or control
circuit
• 45.7 cm (18 in.) gooseneck and mounting flange supplied (515SBG-18X
and 515SBG-18XF only)
Variations
Model 515SBGX: Does not include gooseneck or mounting flange.
Model 515SBG-18X: Includes gooseneck and 76.2 mm (3 in.) diameter
mounting flange.
Model 515SBG-18XF: Includes gooseneck and 44.4 mm (1-3/4 in.) diameter
mounting flange.
Mounting the 515SBG-18X and 515SBG-18XF
Mount the 515SBG-18X or 515SBG-18XF as follows:
1. Thread the supplied hexnut all the way down on the mounting flange.
2. Thread the gooseneck tightly on the flange.
3. Back the hexnut up against the gooseneck, and use a wrench to tighten
the nut firmly against the bottom of the gooseneck.
Mounting the 515SBX onto a Gooseneck
Mount the 515SBGX onto a gooseneck or fixed pipe with a 5/8 in- 27 thread
as follows:
1. Unscrew the black end cap from the microphone.
2. Remove the thin metal washer and the metal spacer.
3. Re-install the washer by sliding it back onto the cable and up into the
end of the microphone.
4. Slip the cable into the gooseneck or pipe and thread the microphone
firmly to the mount.

department at 1-800-516-2525. Outside the United States, please contact
your authorized Shure Service Center.
Connections
These low-impedance microphones are designed for connection to microphone inputs rated at 75 to 300 ohms. Using balanced-line low-impedance cables
permits very long cable lengths without affecting response or level. The RED and BLACK cable leads are the microphone conductors for balanced-line connections;
the shield is connected to the amplifier ground.
For unbalanced operation, connect the BLACK lead to the shield, and use the RED lead as the microphone conductor.
The GREEN and WHITE cable leads are used to control an external relay or control circuit.
