The BLU-Si card is a 32 x 32-channel interface that connects to a BLU link digital audio bus via a standard Cat 5e cable. The BSS BLU-Si card works with these Soundcraft mixing consoles and a wide variety of HARMAN products equipped with BLU link including the dbx PMC16 Personal Monitor Controller, BLU link-enabled BSS Audio Soundweb London devices, and Crown PIP-BLU Programmable Input Processor (PIP) amplifier input/control module.

“The BLU-Si provides an easy way to greatly expand the capabilities of a Soundcraft Si Expression, Si Performer or Si Compact console, without the need to connect the console to a network,” said Noel Larson, Market Manager for Portable PA, Tour and Recording at HARMAN Signal Processing. "For example, a Soundcraft Si Expression or Si Compact 16 can be connected to a dbx PMC16 Personal Monitor Controller to create a highly cost-effective mixing and monitoring system that gives the sound person up to 32 channels to work with and enables everyone in the band to dial in their own personal onstage monitor mix using any combination of up to 16 of these available 32 channels.”

The BSS BLU link is a low-latency, fault-tolerant digital audio bus of 256 channels that can be connected to compatible BLU link-enabled devices using a Cat 5e cable of up to 328 feet in length. The BLU-Si can select sequential banks of 32 BLU link channels and transmits and receives from any BLU link-enabled product.
