WIRING GUIDE FOR THE SPEAKER OUTPUTS

The Nuance Speaker Outputs are 1/4" TRS connections that are
optimized for feeding balanced TRS or XLR inputs on a pair of
powered monitors or power amplifiers. When connecting to balanced
devices, your cables should be wired Tip = Hot (+), Ring = Cold (-), and
Sleeve = Ground (see Fig. 1 below). Should you encounter a ground loop
that causes humming through your speakers, you can disconnect the
ground at the destination end of the cable (Fig. 2).
However, there may be certain instances where you would like to
connect the Nuance to devices with unbalanced inputs, such as 1/4" TS
connectors.
In these cases you should avoid connecting unbalanced TS connectors
to the Nuance Speaker Outputs. Doing so will short out the signal on the
Ring of the TRS jack, which could result in increased distortion. Instead,
you can use TRS jacks with the Ring conductor disconnected, as shown
in Fig. 3 below. TRS to TS adaptor cables should also be avoided unless
you can confirm that the Ring on the TRS is disconnected.
Note that these instructions apply to the Speaker Outputs only. The
Nuance Source Inputs can accept both TRS or TS jacks without issue,
though we recommend using balanced cabling where possible for best
results.
