(1RU) through package with servo-balanced XLR inputs and
1/4" TS outputs for each preamp
• Highest quality components and advanced design with ultralinear, high bandwidth operational amps for no-compromise
crystal clear audio with exceptionally low noise and negligible
distortion

with up to 75dB of gain
• +48V Phantom Power with individual Phantom On/Off switches
and Phantom Power On LED indicators on each channel
• Rugged construction for maximum long-term reliability
