Available in 16 24 and 32 channel configurations the GB2 is designed for installed sound and A/V applications that don’t require all the sophisticated functionality of the GB4 and GB8. However the GB2 is a genuine GB Series console in every respect with sound quality assured by GB30 Mic Pre and Equaliser designs and reliability by the same rugged build quality that has made the GB4 and GB8 so dependable in demanding professional applications. Along with six Aux busses and an integral 6 x 2 matrix four subgroups are provided as two stereo pairs with a unique facility for adjusting the width of the stereo signal across the stereo mix. The channel pan settings are retained on the group outputs while the degree of stereo separation to the mix bus is independently adjustable from full stereo through to mono.
The GB2 also features two stereo input channels with separate mic and line inputs. In normal use the mic inputs are routed to the local channel and the line inputs act as a stereo return to the mix bus. Selecting the line input to the local channel overrides the mic inputs.
FEATURES:
• 16 channel frame size
• 12 busses
• 2 full feature stereo channels
• 2 stereo returns (on stereo channels)
• 6 Aux sends
• 4 sub groups (paired)
• 6x2 output matrix
• GB30 mic preamp and precision equalisation circuitry
• Direct outputs on every channel
• Talkback facility
• 100mm faders
• Switchable 48V phantom powering on every channel
• 100Hz high pass filter
• 12-segment LED metering
• Record output
Line inputs on the stereo channels can also act as a stereo return.
