The EL-030 is a 3m(9.8ft) long extension cable for 3-pole (TRS) microphones.
The cable has a lapel clip, allowing you to connect an ETM-001 directly to it and use the ETM-001 as a lavalier microphone when shooting videos with a GoPro, DSLR or for audio recordings with a digital voice recorder like the Zoom H1.
Or you can simply add more length to the ETM-006 and ETM-008 microphones.
Need something longer than 3m? Check out the EL-050(5m, 16.4ft). Need a little shorter? EL-013(1.3m, 4.3ft)
1 x extension cable, 1 x lapel clip, 1 x handy leather pouch
