Accessories

// 

DTP 40 Mts - Mic mount

Rubber  microphone  mount.  Provides  firm  grip  and  attenuates  structure  borne 
noise . Compatible with 3/8" and 5/8" threads .

// 

LCT 40 Wx – windscreen  

This one is especially useful when using the microphone outdoors, to shield the 
capsule from wind . Can also be used for vocal recordings, to protect the capsule 
from moisture .

//

 

DTP 40 Lb - transport bag 

Microphones which are not in use should not remain on the stand gathering dust 
or be unnecessarily exposed to humidity . Unmount it and put it into the supplied 
DTP 40 Lb transport bag .

//

 LCT 40 SH - shock mount (optional)

A shock mount is recommended for most recording applications as it reduces 
unwanted structure-borne noise .The open front of the shock mount allows you 
to position the microphone as close as you like to the source .

// 

LCT 50 PSx - magnetic pop filter (optional)

The magnetic pop filter was designed to perfectly integrate with the design of the 
microphone and its shock mount. A pop filter not only helps to avoid plosives and 
hisses on your recording, but also protects the condenser capsule from being 
exposed to moisture .

Compatible with LCT 40 SHx, LCT 40 SHW, LCT 40 SH .
