Unbalanced 1/4” wiring can be done with either a two- or three-conductor (TS or TRS) plug. A
two-conductor (TS) plug automatically grounds the signal negative input, whereas a three-conductor
(TRS) plug, wired unbalanced, provides the option of leaving the negative input open or grounded. We
recommend that you ground the unused negative input (this can be done by wiring the ring and sleeve
of the TRS plug together).
The TRS input is summed through a balanced input amplifier with the XLR input, allowing both inputs
to be used simultaneously. Input specifications apply to both.

Deluxe to proper levels as required.

8. VOLTAGE-SELECT SWITCH: Provides two selections, 115V AC and 230V AC, and should
be set to match the “house supply” (receptacle) voltage of the country or location in which the
speaker is used. The 115V setting is correct for the USA and Japan, while the 230V setting is
correct for most of the UK and Europe.
9. POWER SWITCH: This switch turns the monitor on and off.
