sE Electronics X1 A Large Diaphragm Condenser Microphone

The X1 A: It Could be Your First Mic, But It's One You'll Want to Keep Forever

There's a New Entry Point to sE's Acclaimed X1 Series, And It's Breaking the Performance Barrier for Every Mic in Its Class (Again)

When it was introduced in 2011, the X1 brought a new level of quality to its price point, competing easily with microphones costing several times as much. But that didn't stop sE from trying to outdo themselves again.

With a newly-developed condenser capsule and an exterior based on the rugged metal chassis of the X1, the X1 A offers first-class sound & specifications at an even better "home studio" cost, featuring an extremely natural frequency response, massive SPL-handling capabilities (150dB!), switchable attenuation and low-cut filters, and a perfectly balanced sensitivity level - so it's at home on absolutely any source.

From Vocals to Acoustic Instruments to Electric Guitars or Percussion, the X1 A is the Perfect Choice for Any Musician Seeking a High-Quality Microphone with an Entry-Level Price Tag

All-Metal Housing and Premium Finish

Unlike the cheaply constructed bodies of some other "entry-level" microphones, the X1 S's all-metal chassis provides efficient rejection of any electrical interference and noise - and the high-quality finish ensures a great look for years to come. 

Completely New Acoustic Design

The X1 A's new condenser capsule design is a work of art, delivering stellar sonic performance on any source with incredible speed, accuracy, and well-balanced frequency response. The electronics have also undergone a complete overhaul, and exhibit better specifications and sound - on and off the bench - than any other microphone in its class.

Attenuation & Low Cut Switches

The -20 dB pad switch on the left provides extended dynamic range, enabling a wide range of applications and close-mic techniques for even the loudest instruments...think super-heavy electric guitars, fortissimo brass instruments, and heavy-footed kick drums. On the right, the 100 Hz low-cut switch helps eliminate low-frequency rumble or footfall noise, and compensates for excessive bass with close-mic techniques (proximity effect).
