Qt PRO™ Control Unit — OUTSIDE

Qt PRO

Control Unit — INSIDE

INSTALLATION PROCEDURE

CONTROL UNIT

• Mount control unit on wall (3 screws required).

• To power the unit, connect DC end of power brick

to the 2.5 mm barrel jack located toward the top of

the backplane (#3 in diagram above).

• Carefully trim, label, tie-down and attach emitter

homeruns to their designated Zone port. Record

the destination of each homerun on the door label.

Tie-down and attach any power, paging, music

and LAN wires.

• To connect a balanced paging signal, ﬁrst be sure

that the unit is powered OFF. Connect the signal

wires to + and – and the shield to GND. If the shield

is connected to GND at the paging source (e.g. the

PBX), you may want to leave the shield unconnected

at the Qt PRO™. Experiment with shield connected

and unconnected at Qt PRO™ and select approach

yielding best sound performance.
