Страница: 2 / 8

Overview
The SGM-250CX and SGM-250MX are short length, condenser shotgun
microphones that are ideal for mounting on video cameras equipped with XLR
microphone inputs. As part of Azden’s 250 microphone model series, you can
expect professional quality sound that preserves the natural characteristics of a
speaking subject. The supercardioid pickup pattern will also minimize the
recording of extraneous noise and better focus on the sound in front of the
camera.
Integrated with each microphone’s design is a hardwired XLR cable for
convenient connection to camera microphone inputs. The CX model includes a
standard, 3-pin XLR output connector for equipment with standard XLR
microphone inputs. The MX model includes a 3-pin mini-XLR connector for
equipment with mini-XLR microphone inputs.

SGM-250CX / SGM-250MX Professional Compact Cine Mic
This microphone’s highly sensitive, condenser element is powered by standard
48 V phantom power, which most standard and mini XLR microphone inputs can
provide. The microphone includes Azden’s SMH-X shock mount which attaches
to a standard size camera shoe slot, as well as ¼”- 20 threaded mounts and
tripods. Also included are diameter expander sheets for universal compatibility
with ring-clamp style microphone mounts.
Power
Phantom power is a DC voltage supplied through a balanced microphone cable
and used to power the electronics of the connected microphone. Most
professional cameras, mixers and audio interfaces with microphone XLR
preamps have the ability to supply phantom power. If the equipment you use
does not, you will have to utilize a separate external phantom power supply.
Most commonly, phantom power is supplied at 48 V. This is the optimum voltage
for the SGM-250CX and SGM-250MX. It is possible that your connecting
equipment supplies a different voltage. This microphone is rated to work on a
voltage between 11 and 50 V, however, performance will degrade with lower
voltages and damage to the electronics could result when using voltages in
excess of this range. It is recommended that you consult the manuals of any
equipment you intend to use with the microphone beforehand. Please note that
the warranty does not cover damage caused by using phantom power beyond
what the microphone is rated for.
Connecting to Camera
To connect the SGM-250CX to a camera, it must have a standard 3-pin XLR
microphone input available. To connect the SGM-250MX to a camera, it must
have a 3-pin mini-XLR microphone input available. The input must also supply
phantom power.
Be aware that for some cameras, it is required that you change the audio
settings in order to use audio from an external microphone. Please check your
camera’s manual.
Diameter Expander Sheets
The SGM-250CX and SGM-250MX come with two diameter expander sheets.
These sheets are made from flexible rubber, have an adhesive backing, and are
meant to be wrapped around the base of the microphone to allow it to better fit
in ring-clamps larger than ø 21 mm. Be careful not to cover the cancellation slots
of the microphone barrel when using the expander sheets.
