Overview
The SGM-250H is a professional hypercardioid condenser shotgun microphone intended for video production applications. As part of Azden’s Ni-Go-Maru Series (250) microphones, you can expect high-level performance, natural sound quality and excellent build quality, all backed by one of the best product warranties in the industry: a limited 10-Year Warranty against manufacturer defect (online registration required).
The characteristics that set the SGM-250H apart from the rest of the Ni-Go- Maru Series are its hypercardioid mic element and 50% longer interference tube. Together, these design elements combine to create a highly focused pick up pattern that’s more sensitive to on-axis sounds and better at rejecting sound approaching from the sides.
This makes the SGM-250H well suited for recording in challenging acoustic environments. Whether the space you’re in has a lot of unavoidable background noise, or produces significant reverberation, the SGM-250H will do a better job at isolating your speaking subject and recording clear audio.
Low-Cut Filter Switch
When engaged, the low-cut filter switch (a.k.a. high-pass filter) will
attenuate frequencies below 75 Hz at the rate of -3 dB per octave. The switch
has two positions:
It is not recommended that you adjust the low-cut filter switch while recording as doing so may produce an audible noise in your recording.
When to engage the Low-Cut Filter Switch?
It’s most likely best to leave the low-cut filter switch OFF unless your recording environment is plagued with an unavoidable, low-frequencynoise. Fans, electric motors, HVAC systems, cars on a busy road and wind are some examples of what can produce unwanted noise in the lower frequency range. Bear in mind that a low-cut filter cannot totally eliminate noise, but merely reduce it, which in turn can improve the intelligibility of recorded speech.
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 volts. This is the optimum voltage for the SGM-250H. It is possible that your connecting equipment supplies a different voltage. This microphone is rated to work on a voltage between 11 and 50 volts, 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 or Audio Recorder
To connect the SGM-250H to a camera or audio recording device, use a high- quality, balanced XLR microphone cable (sold separately). Be sure that phantom power is switched on for your mic input and be aware that you may also need to adjust your camera’s or audio device’s settings before signal from the microphone can be recorded.
