sE Electronics X1 A

Cardioid Condenser Microphone

The sE Electronics X1 A is a versatile electret condenser microphone built for vocals, acoustic instruments, guitar amplifiers, percussion, and general recording applications. Its 2/3-inch cardioid capsule combines a wide 20 Hz to 20 kHz frequency response with low self-noise, high SPL handling, a switchable -20dB pad, and a 100Hz low-cut filter for flexible use in home, project, and professional studios.

sE Electronics X1 A Competitive Differences

• 2/3-inch electret condenser capsule provides detailed full-range capture for vocals and instruments
• Switchable -20dB attenuation pad increases maximum SPL handling from 130dB to 150dB
• 100Hz low-cut filter helps reduce rumble, foot noise, proximity effect, and unwanted low-frequency buildup
• 16dBA self-noise supports clean recording of quieter sources
• All-metal chassis provides durability while helping shield the microphone from electrical interference
• Integrated windscreen adds protection against unwanted air movement and plosive noise
• Gold-plated XLR connection provides a durable and reliable balanced audio connection

sE Electronics X1 A Description

The sE Electronics X1 A is designed as an adaptable condenser microphone for engineers, musicians, content creators, and home-studio users who need one microphone capable of handling a broad range of sources. Its permanently biased 2/3-inch electret condenser capsule uses a cardioid pickup pattern to focus on sound arriving from the front while reducing pickup from the rear.

With a frequency response of 20 Hz to 20 kHz, the X1 A is suitable for vocals, acoustic guitars, percussion, amplified instruments, brass, and other full-range sources. Its 16dBA equivalent noise level helps preserve detail when recording quieter material, while a maximum SPL of 130dB without attenuation provides substantial headroom for louder instruments.

Engaging the -20dB pad extends maximum SPL handling to 150dB, making the microphone useful for close-miking high-output sources such as guitar cabinets, drums, and brass instruments. A switchable 100Hz low-cut filter with a 6dB-per-octave slope helps remove low-frequency rumble and can reduce excessive bass caused by close-miking proximity effect.

The microphone is housed in a rugged all-metal body with an integrated windscreen and gold-plated 3-pin XLR output. It operates from standard 48V phantom power and includes a microphone clip and thread adapter for mounting to common microphone stands.
