[. . . ] For a TRS stereo input configuration, connect a Tip-Ring-Sleeve stereo to dual Tip-sleve (mono) RCA jack cable. This is a very specific jack referred to as a insert jack and must be purchase at a specialty store, to the rear panel LEFT and RIGHT RCA Input's on the RA102. This cable may come from a mixer's AUX output for example. To send a mono signal to the RA102: connect a mono XLR or RCA to both the LEFT and RIGHT inputs at the same time this will require a specialty cable. The mono signal will be fed to both the right and left sides of the headphone outputs.

Unpack and inspect the RA102 box and package. If obvious physical damage is noticed, contact the carrier immediately to make a damage claim. We suggest saving the shipping carton and packing materials for safely transporting the unit in the future.

JOIN EXPLANATION: The JOIN section is for connecting RA102's directly together so you can use one source plugged into the first RA102 and by connecting them with the JOIN in and outs you can have as many headphone outs as you have units. To properly connect the JOIN: Plug source material into the first RA102, then plug a TRS 1/4" cable (also referred to as a 1/4" stereo cable) from the JOIN OUT of the first unit into the JOIN IN of the second unit. Repeat the JOIN in and out scheme for as many RA102's as you need, only plugging the source material in the very first unit in the chain.
