    The SGM-250CX is a short length, condenser shotgun microphone that is ideal for mounting on compact digital cinema cameras, as well as DSLR and mirrorless cameras equipped with XLR adapters. Measuring at a mere 6 inches in length, the SGM-250CX can easily stay out of the way. Integrated in the microphone’s design is a hardwired, 13-inch XLR cable for convenient connection to camera microphone inputs. The microphone’s highly sensitive, condenser element is powered by standard 48 V phantom power, which most XLR microphone inputs can provide.

    The SGM-250CX includes Azden’s SMH-X shock mount which mounts to standard size camera shoe slots, as well as ¼”- 20 threaded mounts and tripods. Also included are diameter expander sheets for universal compatibility with ring-clamp style microphone mounts.

    Legendary Natural Sound

    The SGM-250 microphone series has become notable in the industry for its natural, professional sound. Specifically tuned to preserve the natural qualities of a speaking subject. While other manufactures hype-up the bass response on their microphones, making the audio sound muddy, or over-accentuate high mids, making dialogue tracks sound harsh, you can expect the SGM-250CX to accurately record the sound of your scene.

    Not Just A Reference Microphone

    You can rely on the SGM-250CX for great reference audio, but it’s capable of more than that. Its low noise, and wide frequency response performance means it can capture audio good enough for the final cut. Whether you run and gun, mount to a pistol grip or a boom pole, the SGM-250CX can be your go-to mic for great dialogue capture.

    • What is phantom power and does my microphone need it to work?

      Phantom power is a DC voltage supplied through a balanced microphone cable and is used to power the electronics of the connected microphone. Most professional cameras, mixers and audio interfaces with microphone XLR pre amps have the ability to supply phantom power.

      Most commonly, phantom power is supplied at 48V. This is the optimum voltage for Azden's microphones. It is possible that your connecting equipment supplies a different voltage and each Azden microphone has a recommended voltage range that can be used. Be advised that microphone 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.

      In general, if your Azden microphone does not have a battery compartment it will require phantom power to work. Some microphones have the ability to use a battery for power or phantom power, while others may only work on battery. Check your manual or the product page for your model on azden.com to be sure.

      Phantom power is not used at all with lapel, headset and DSLR camera microphones. These microphones do need a power source, but it is a much lower voltage. This type of power is typically called plug-in power (PiP) and is usually provided on mini-jack inputs on cameras and wireless transmitters. Attempting to use phantom power on a microphone that need plug-in power will very likely result in damaging the microphone element.

    • What does cardioid, super cardioid, omni-directional and uni-directional mean?

      All of these terms are used to describe a microphone’s polar or pick-up pattern. The simplest being omni-directional, which means the microphone will pick up sound equally from all directions.

      Cardioid and uni-directional are two interchangeable terms that are used to describe a microphone that is most sensitive to sound coming in directly in-front of the microphone element (on-axis) but will reject some sound coming from the sides and nearly reject all sound coming in from behind. These microphones are better at isolating a sound source in a noisy environment and are best used on a speaking subject up close.

      Super-cardioid is a hyper-directional pick-up pattern, which is very sensitive to all sound in the front of the mic element, and does a very good job at rejecting sound coming in from the sides. Sound sensitivity from the rear is somewhat reduced but not totally. This kind of directionality is found in many of Azden’s shotgun microphones and is best suited for focusing in on sound sources from a distance but can also be used up close.

    • How can I use my Azden microphone with my smartphone or tablet?

      Any of Azden’s microphones with a 3.5mm mini-jack output can be made to work with a smartphone or tablet using the HX-Mi TRRS Mic/Headphone Cable. Compatible Azden microphones include EX-503, EX-503L, EX-505U, EX-50L, ECM-44, HS-9, HS-11, HS12, CM-20D, SGM-990 and SGM-DSLR. Azden’s stereo microphones can work with the HX-Mi but only in mono, since mobile devices do not have stereo microphone inputs. These microphones include SMX-20, SMX-10 and SMX-5. Also available is the SGM-990+i which comes complete with an adapter cable to make it compatible with mobile devices.

    • My microphone is not working properly. Can you repair it?

      Yes we can. See the Service And Warranty page for details. We recommend you give a call first to see if we can troubleshoot your problem over the phone.

    • I have a DSLR, mirrorless or other compact camera. Which Azden microphone is best for me?

      First make sure your camera does have a dedicated 3.5mm microphone input.

      Azden makes a line of camera mount microphones specifically for these types of cameras. The current models are SGM-990, SMX-30, SMX-15, SMX-10 and SMX-5.

    • Where can I buy a replacement shock mount, windscreen or lapel clip for my microphone?

      Yes. You can find these items and more for sale on our website www.azdenproshop.com.

    • Can I use your headset microphones to make phone calls?

      No. While the microphone itself may work for your application, Azden’s headsets do not have a speaker or earpiece for phone use.

    • What does a low-cut filter do on your microphones?

      A low-cut filter is designed to reduce the volume of low frequencies as recorded by the microphone. This can be handy to reduce low frequency background noise such as wind, HVAC systems or traffic. It can also be used to reduce increased bass response due to proximity effect.

      The design of the filter is different depending on which microphone. On the SMX-10 for example, engaging the low-cut reduces low frequencies at 6dB/octave below 200Hz. On the SGM-250, the low-cut rolls off at 160Hz at 3dB/octave.

    • Can I use my Azden microphone in wet conditions?

      Azden’s microphones are not waterproof but should be able to stand up to a little moisture and light rain if exposed infrequently. If you must use your microphone in the rain, it’s best that you try to keep it covered.

    • Which Azden microphones are best for broadcast and film?

      Azden’s SGM line of shotgun microphones are designed for this application. The SGM-3416 and 3416L are Azden’s high performance shotguns, designed to deliver the high quality that any broadcast professional or filmmaker would demand. The SGM-250 and SGM-1X are both great choices for boom work or studio use and were designed with the budget-conscious filmmaker in mind. The SGM-PII and SGM-PDII are great choices for on-camera mounting, with their shorter barrels designed to stay out of view of the camera lens.

    • Can I use rechargeable batteries with my Azden microphone?

      We recommend using standard alkaline batteries. We do not recommend using rechargeable batteries with any of our VHF and UHF wireless units, mixers or microphones. In general, rechargeables will not last as long as standard alkaline batteries.

    • How can I get rid of the hiss in my recordings when using a DSLR camera?

      When most people hear noise in their video recordings, they assume it must be the fault of the connected audio equipment. While this is entirely possible, it is not often the case. The most likely culprit is actually your camera’s low quality microphone pre-amp.

      Why is your camera’s pre-amp not so good? Camera manufacturers tend to put their development dollars into the functions related to photography. Sound is usually an afterthought and unfortunately the mic inputs on most DSLR cameras are designed to be good enough to work, but are far from being a professional audio input.

      Why is the pre-amp adding noise? A microphone pre-amp adds gain (volume) to a connected microphone. And all pre-amps have an inherent noisiness, called a noise-floor. Low quality pre-amps tend to have a higher noise floor and when gain is utilized to increase the volume of the microphone, it also increases the level of the noise floor. This usually manifests as a hiss or white noise being audible in the soundtrack of your video.

      What’s the solution? Whether using one of Azden's DSLR microphones or professional XLR shotguns microphones with a 3.5mm adapter, the best options for better sound quality are to use an audio adapter/mixer (like the FMX-DSLR) or to use an separate portable recording device.

      In both cases, these devices use better, higher quality microphone pre-amps and should reduce any inherent noise present in your video recordings.
