User guide, E5 2 4 d, Xy stereo electret microphone
－3－
The E524D incorporating 2 electret condenser capsules in an XY 90°
arrangement. This popular arrangement provides easy to achieve
stereo Hi-Fi result. Suitable for choir, orchestra, drum sets, solo
instrument or chamber music recording, with good background and
spacious capture.
Cardioid left and right channels emphasis on-axis sound and
suppress rear bound sound that brings the on-axis performance to the
audience and captures minimum direct sound from audience seats.
Matched capsules is vital for stereo microphone, XY arrangement
picks up most sound around axis that demands uniform polar
response across frequency bands in order to reproducing nature
sound. The matched capsules on E524D enable the user to record
nature stereo sound easily.
The E524D's low inherent noise and high sound pressure level allows
to record in very quiet background noise and sustain very high playing
level. The power source can be internal battery or external phantom
power. The package including an XLR5F to 2 XLR3M cable that
connects both channels to the recording device or mixer. Phantom
power to both channel shall be turn-on at the same time. The E524D
works with 9 to 48VDC. The internal battery is ok to leave it in the unit
when using phantom power. The battery can be a automatic back-up
power for phantom power. Phantom power provides better operating
condition, and user don' t need to worry the battery capacity.
The 1.5V battery is an extremely convenient tool for field
assignments, with the same frequency response and same high SPL
ability.
A blue LED power indicator shows the power condition, it will flash
once during power-up. When the microphone doesn't work or signal
become weaker, it is the time to replace with a new battery. Please
insert the battery according to the polarity indication. When the
microphone is not in use, please switch off the power switch to save
power. If the microphone will not be used for an extended period,
please remove the battery to prevent leakage damage. A good quality
