FMR Audio, +1-512-280-6557 • Balanced Outputs — The RNLA has balanced, non-differential outputs. Although the “cold” part of the signal is not driven (that would be a “differential” signalling scheme), the impedance in both legs are the same, thereby giving your audio the benefit of reduced noise if the RNLA is connected to a balanced line...

We need things done to standards that are very specific and loftier than most. Manu- facturing products here help control important costs and reduce waste (there’s more to producing a product than just considering the costs of labor and parts).

FMR Audio, +1-512-280-6557 new tricks: I’m actually learning to like and find uses for the sonics of the RNLA! • The RNLA has freakin’ Red Knobs — Proof, once again, that there’s “no accounting for taste”, I specified these knobs after a word-association game with my therapist.
FMR Audio, +1-512-280-6557 www.fmraudio.com tion, use the appropriate connectors to mechanically make the connection. For example, if you’re connecting to a destination device with a XLR input connector, then use a 1/4”TRS-to-XLRM cable that passes the TIP signal to XLR pin #2, the RING signal to XLR pin #3 and the SLEEVE to XLR pin #1.
FMR Audio, +1-512-280-6557 • Adjusting the RELEASE control — If you want less compressor action overall, use a slower RELEASE by turning it CW. If you want more coloration, use a faster RELEASE by turning it CCW. • Using the LOG REL control — Engage this function (LOG REL light is illumi- nated) when you want more “pop”...
