Large diaphragm condenser microphone with double diaphragm
3 switchable polar patterns
Extremely constant polar pattern over the entire frequency range for full control
Prethos Advanced Preamplifier Technology for extremely low self-noise, very high dynamic range and extremely fast transient response
Only 4dB equivalent noise level (cardioid) and maximum sound pressure of 131 dB for a dynamic range of 127dB (+7 dB compared to previous model)
2 ultra-thin (2.5µm) 24k Gold coated low mass Mylar diaphragm for outstanding transient response
First-class electronic components and gold-plated internal and external contacts
15dB attenuator to capture even loud sources without problems
Three-stage switchable low cut filter
Built-in, three-layer pop filter reduces breath and wind noise
Rumble filter cuts out low frequency noise sources (below 17 Hz)
Scope of delivery:
1 x A44AM ShureLock Microphone Holder
1 x AK44C zippered carrying case
1 x A44ASM ShureLock elastic mount (spider)
1 x RK383 replacement strap for the spider
1 x A44AVB Velour velvet protective pouch
What a large-diaphragm condenser should have:
The KSM44A comes with everything a high-quality and flexible studio microphone should have: a true dual-diaphragm capsule with switchable polar patterns (cardioid, omnidirectional, figure-eight) for a defined and full sound, an extremely low self-noise, very high sensitivity, a wide dynamic range, reduced proximity effect, and a three-stage switchable low-cut filter.
And what it also has in addition:
A spider and a transport case are also included. With its rugged construction and switchable -15dB pre-attenuation, it can also be used on stage, eg. on electric guitars & basses, strings or overheads.
What does the Prethos Advanced Preamplifier Technology do?
The KSM44A utilizes the proprietary Prethos Advanced Preamplifier Technology. A new milestone in amplifier circuit technology, Prethos incorporates an internal circuit architecture that allows for unprecedented transparent sound reproduction. It enables extremely low self-noise (4 dB in cardioid mode), very high dynamic range and outstanding transient response.
Linear and detailed sound
The KSM44A is equipped with premium electronic components such as the two ultra-thin (2.5 µm) and 24k Gold coated low mass Mylar diaphragms. Internal and external connections are also gold-plated.
