1. 把卡侬(XLR)插头插入麦克风，旋转插头使上面的扣键与麦克
风上的槽口对准，然后将插头推入麦克风，直至扣键定位。
2. 麦克风与连接线分开时，可握住插头，同时按压扣键，然后将
插头从麦克风拉出。

开关的使用
A. 低频衰减：当开关处于 “－”位置时，为无衰减状态，当开关处
“ ”位置时，可均衡近距离拾音时的低频提升效应和降低风噪
声、舞台地板振动声等。
B. 当开关处于“0”位置时，为无衰减状态，当开关处于“-10dB”
时，可使灵敏度衰减-10dB，一般在高声压级大动态拾音场合使
用此功能（如交响乐队的低频鼓、小号等乐器的拾音）。
使用说明
1. 使用时 应先将扩音器或调音台音量控制调小 然后将幻象电源
与麦克风连接好，再打开幻象电源的电源开关，并将音量从小到
大慢慢调节至合适，以免喇叭受到冲击。
2. 用手罩住麦克风头部，或使麦克风接近扬声器，可能产生啸叫声，
遇此情形时，首先降低音量，拉开同扬声器的距离，尽量使麦克
风不同扬声器相对。
3. 麦克风灵敏度高，必须注意不要从高处落下或给予强烈冲击。
4. 麦克风不使用时应存放在干燥清洁的地方，避免在温度、湿度过
高的场所保管或使用，以免影响灵敏度和音色。

Usage
Professional Recording Microphone
TAKSTAR SM-7B is a professional condenser microphone
for recording which adopts advanced SMT, precision
control circuit with Pressure Gradient Transducer cartridge
and a large vapor-deposited gold diaphragm to achieve
high sensitivity, extended frequency response, no crossover
distortion and low self noise.
The Zinc-die casting housing is spray printed. Its standard
XLR (F) connector matches all kinds of audio equipment.
SM-7B is tailored for broadcasting, television studios,
recording studios, stage performances, etc.
Specification
Element: Pressure Gradient Transducer
Polar Pattern: Uni-directional
Frequency Response: 20Hz-20kHz
Sensitivity: -37dB±2dB (0dB=1V/Pa at 1kHz)
Output Impedance: 100Ω±30% (at 1kHz)
Max. Input SPL: 130dB (at 1kHz≤1% T.H.D)
S/N Ratio: 22dB
Low Frequency Attenuation: 100Hz/oct 10dB
Phantom Power Requirement: 48V DC
1.Insert the XLR connector into the microphone. If necessary, rotate the
connector to align the key on the connector and the groove in the
microphone. Push the connector into the microphone until it clicks.
2.To disconnect the cable and microphone, grasp the connector while
depressing the tab. Pull the connector away from the microphone.

A. Low frequency attenuation:
“ ” no attenuation;－
it can balance the low frequency rising effect of short distance “ ”
pickup and reduce the feedback as well as protect from howling;
B. Sensitivity attenuation:
0 no attenuation;“ ”
-10dB” it fixes the sensitivity on –10dB level, shortens the pickup “
distance, eliminates the noise: this function is usually used for high
SPL and large dynamic pickup occasions (i.e. the pickup of low
frequencies of small instruments of symphony orchestra).
1. Turn on your amplifier or mixing board and set the volume control to
minimum position, To connect the phantom power to the microphone
turning on the phantom switch, accommodate the volume control from
low to high so obtained effect to your moderate level for protected the
sauna from pounding.
2. If the head of the microphone is covered by hand or brought close to the
speaker, a howling sound may be generated. To prevent this, first decrease
the volume, then place the microphone so that it is not pointed to the
speaker and that there is a sufficient distance between the microphone
and speaker.
3. The sensitivity of cartridge is very fine, Don't do drop. Hit it or apply
strong shock to it.
4. To maintain the sensitivity and quality of sound reproducing, avoid exposing
it to moisture and extreme temperatures.
