Thank you for choosing Senal.
The Senal ENG-18R/RL is a broadcast-quality omnidirectional dynamic microphone. The
omnidirectional dynamic capsule picks up sound in a 360° pattern and does not require a battery
or phantom power, making it a reliable choice for critical field applications. The microphone’s
exceptionally low handling noise and resistance to wind noise and vocal plosives make it perfect for
professional ENG applications like live reporting, interviews, and press conferences.
At multiple areas inside of the microphone, natural rubber with special shock-absorbing properties is
bonded to carbon steel rings to isolate the sealed inner shell from the outer shell. This system helps
protect the microphone capsule from impacts and inclement weather, and dissipates kinetic energy,
dramatically reducing handling noise and resonance due to rustling and knocking.
The microphone incorporates multistage wind protection to minimize wind noise and vocal plosives.
A mesh grill, acoustic foam, acoustic fabric, and a second layer of acoustic foam work to diffuse excess
sound pressure from wind and breath. A fixed rigid carbon-steel ring with a unique bullet-shaped
design disperses breath to minimize vocal plosives.
The EQ curve is tailored for broadcast use, with a gradual low-frequency roll-off to keep out unwanted
rumble, a pronounced midrange to ensure speech intelligibility, and a high-frequency roll-off to
eliminate hiss and sibilant distortion. Whether broadcasting on television, AM/FM radio, or over

Introduction
the internet, the ENG-18R/RL is designed to
ensure that dialogue cuts through the mix, and
can be broadcast live without EQ adjustment.
Both models feature a durable aluminumalloy shaft designed for EMI rejection and
reduced internal resonance. They each come
with a matte black finish for a professional
appearance. The ENG-18RL is slightly longer to
accommodate a mic flag.
