The XL-TP is an in-line barrel adapter to convert phantom power (12-15 V phantom ONLY) to 12 V T power for T powered microphones. With the 12 or 15 V phantom power setting on Sound Devices MP-1, MixPre, and MP-2 field production products, the XL-TP efficiently provides T power for microphones which require it. Because it works at a the lower phantom level on these products, the XL-TP extends battery life when powering T-powered microphones.
Note: The XL-15 will not work if 48 V phantom power is supplied.
