avoid adapters as they can pick up interference/hummm from the equipment if it's not grounded. Even if grounded you'll still get a hiss/humm/buzz
Best to get ready made RCA-TRS cables as in one end is TRS the other end is RCA... I personally like the TRS-TRS connection between the 900nexus & RMX, it's really the same signal /quality if you use the RMX's RCA inputs- just avoid adapters & u should be alright
