XONE:02 Service Manual 9
Cables and Connections
The XONE:02 uses professional grade 3 pin XLR, 1/4" TRS jack and RCA PHONO sockets.
The following mating plugs may be used:
The 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.
