Cables and Connections
The XONE:32 uses professional grade 3 pin XLR, 1/4" TRS jack and RCA PHONO sockets. The following
mating plugs may be used:
The microphone input XLR connector is 3 wire balanced. This has 3 connector pins: Pin 1 = ground (screen),
Pin 2 = signal hot (+), Pin 3 = signal cold (-). The jack sockets are the 3 pole TRS type. These are wired to
work with either the balanced TRS or the unbalanced 2 pole TS type plugs without cable modification. The
sockets have 3 connector pins: Inputs and outputs are Tip = signal hot (+), Ring = signal cold (-), Sleeve =
ground (screen). Headphones are Tip = left, Ring = right, Sleeve = ground. The RCA phono connectors are 2
wire unbalanced to connect to equipment such as CD players, turntables and domestic amplifiers.
To ensure best performance, we recommend that you use high quality audio cables and connectors, and take
time to check for reliable and accurate cable assembly. It is well known that many audio system failures are
due to faulty interconnecting leads. Avoid reversing + and - on balanced connections as this will result in
reverse polarity connections which may cause signal cancellation effects. Refer to the cable diagram for how to
wire unbalanced to balanced connections. It is fine to use a Y-adapter to feed one output to several inputs,
but never use a Y-adapter to sum two outputs into one input.
