Preamp Module for the Aurora(n)

For the first time ever, we have designed and built a microphone preamp to compliment the capabilities of the Aurora(n). The 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 compliments 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-PRE4’s in either Thunderbolt or USB. The LM-PRE4 and the Aurora(n) PRE 1608 are available now.
