Audio Technica AT831b Miniature cardioid condenser microphone

This clip-on lavalier mic provides crisp, full-sounding voice pickup and excels as an instrument mic, especially for pickup of acoustic guitar with included AT8444 guitar adapter. It offers excellent gain before feedback and suppression of background noise. An integral 80 Hz high-pass filter provides easy switching from a flat frequency response to a low-end roll-off. It operates on battery or phantom power.

The e 608 is a super-cardioid microphone ideal for almost invisible clip-miking
of woodwind (except certain Flutes), brass and drums. A newly developed clamp
and gooseneck mounting enables the capsule to be positioned close to the signal
source for high realism and high-level output.

Features
Rugged reinforced glass-fibre body
Shock-mounted capsule provides low sensitivity to impact and handling noise
Hum compensating coil
Extremely robust connection cable with XLR connector
Delivery Includes
1 e 608
1 microphone clip

The smartLav+ is a broadcast-grade wearable microphone designed for use in a wide range of film, television and broadcast scenarios, or wherever broadcast quality audio is required in a discreet, portable format without the complication and expense of additional wireless equipment.

With the smartLav+ the user simply mounts the microphone on the talent, connects it to a smartphone or tablet headset jack and records via the RØDE Rec app for iOS, or any other audio app of their choice.

By employing a professional quality omni-directional condenser capsule the smartLav+ picks up sound equally from all around the microphone, allowing for versatility when mounting and ensuring a high degree of user-friendly operation.

A foam pop shield is supplied to minimise wind noise and vocal plosives (hard ʽbʼ, ʽtʼ and ʽpʼ sounds), as well as a durable mounting clip with in-built cable management. Its Kevlar® reinforced cable ensures that you never stretch or snap your microphone under normal usage conditions.

The smartLav+ is compatible with any audio app that accepts input from the headset connection, however it has been designed to pair perfectly with RØDEʼs RØDE Rec app for Apple iOS devices. RØDE Rec turns the userʼs iOS device into a fully-featured field recorder, with a wide range of equalisation presets to suit various recording situations, in addition to professional editing functions and the ability to publish to SoundCloud and Dropbox direct from the app.
