Description
Lynx LM-PRE4 Preamp Module
For the first time ever, we have designed and built a microphone preamp to complement the capabilities of the Aurora(n). The Lynx LM-PRE4 not only adds the flexibility of four channels of mic/line/Hi-Z inputs but also adds an additional four channels of A/D conversion. The LM-PRE4 is sonically matched for the Aurora(n) with all the transparency, detail, and flexibility you’ve come to expect from Lynx. The convenience and utility of this new high-performance preamp not only complement the interface but when combined with the Aurora(n)’s built-in microSD recorder the LM-PRE4 transforms the Aurora(n) into a stand-alone mobile recording device. With a total of 16 ins (8 preamp ins plus 8 line ins) and 8 line outs, the Aurora(n) PRE-1608 comes with two LM-PRE4s in either Thunderbolt or USB. The LM-PRE4 and the Aurora(n) PRE-1608 are available now.
Key features
