Specifications
Totally re-engineered and derived from
designs used in Soundcraft’s
acclaimed MH Series professional
live sound consoles, they gift the
LX7ii with an exceptionally open sound
and an almost unnervingly low noise floor.
KEY FEATURES:
• 32 channel frame sizes* •GB30 mic preamp and precision
equalisation circuitry •True 7-bus architecture •2 stereo inputs •2 stereo
returns •Channel direct outputs •Talkback facility •100mm faders
•+48 phantom power •6 aux sends, 4 of which are pre/post switchable
•18dB/octave high pass filter •Group and mix inserts •12-segment LED
metering •Integral universal voltage, switched-mode PSU for light weight
ADVANCED SOUNDCRAFT TECHNOLOGY
NOW COMES IN MEDIUM SIZE
