I have a Slim Devices Transporter that has two RCA outputs and two XLR outputs. I use an Arcam AV8 on analogue direct mode to pass through the Transporter signal. However, I do not know how to get my sub to play in this configuration. Can anyone help? Is there an easy way to do this? I am likely going to be picking up the new JL Audio Fathom 113 in the near future and it has an XLR input and an RCA input but does not have a high level input. In the meantime (presently) I only have an LFE option on an old sub. Any help would be great!! M.
