These 2RU units offer different configurations but share features. The SB 8.8 offers eight mic/line inputs and eight line level outputs. SB i16 offers sixteen mic/ line inputs. Both models feature a pair of redundant RJ45 Dante network connections, a pair of network extension connections, GPIO connectivity and redundant PSU’s. They have individual signal present, phantom power and local attention LEDs to provide intuitive front panel feedback. They feature inbuilt limiters and SSL’s innovative AutoPad system that automatically applies a Pad according to gain setting. The AutoPad is applied if the gain is set at a low value that would require a pad to achieve making the entire possible mic gain range seamlessly available at all times. An Audition feature provides an automatic gain reduction when checking mic levels, greatly simplifying pre show mic checks for operators of any skill level.
