Description

The ECM888B is a 1/4" standard measurement microphone with internal

battery. No external power needed for easier connection to various

devices. Such as real time analyzer, PC based measurements, or palm

size devices. Wide and flat frequency response makes this ECM888B an

ideal measurement and recording microphone.

Features

Cautions

! Wide frequency response from 20Hz to 20KHz.

! 1/4" industrial standard dimension.

! Omni directional.

! Internal battery, 4LV44, 6V battery

! All metal structure, durable and long lasting live time.

1. When the microphone is connected, do not un-screw the microphone

that may cause impact signal to the connected system.

2. Turn off the level on the audio system before disconnecting the

microphone.

3. Battery life time is 300 hours. If the signal is low or no signal,

replace the battery.

4. Before replace the battery, disconnect the microphone from the

system.

5. Insert the battery according to the illustrated polarity on the bo

dy.

Anode shall point toward the XLR3M plug. Cathode shall point to the

capsule tip. If the battery is not properly inserted, the microphone

will not be damaged, but will not work either.

6. To save the battery power, remove the battery when the microphone

will not be used for a long period.

7. Place foam wind screen when in outdoor to reduce wind noise.
