GENERAL
The Shure FP33 is a three-input, two-output portable ste-
reo mixer designed for professional electronic news gather-
ing (ENG), electronic field production (EFP), and on-loca-
tion film production. The FP33 mixer sets a new standard
for portable mixer performance and features. An exception-
ally low-noise design makes the FP33 ideal for use with dig-
ital transmission links or digital video and audio recording
media, including DAT. Lightweight, compact, and rugged,
the FP33 is designed to withstand the most demanding field
production conditions.
All types of dynamic and condenser microphones may
be used with the FP33. The mixer provides 48 V phantom,
12 V phantom, and 12 V T (A-B) power for operating con-
denser microphones. It will operate for at least 8 hours on
two 9 V alkaline batteries. An external 12-“30 Vdc power
source, such as a Shure PS20 or PS20E ac adapter, may
also be used.
