12 Volt Trigger Outputs
Each of the four zones has its own 12 volt output jack for triggering on amplifiers, cooling equipment or other
devices. The 12V output for a particular zone will be activated when music starts to play in that zone. When
the music stops the 12V trigger will stay on for an additional 30 seconds before turning off. This 30 second
turn-off delay is done to reduce the chance of a triggered amplifier turning off between tracks or from short
pauses in the music. The 12V trigger in each zone is rated at 50mA output.
Note:
If the whole house controller or preamp’s 12V trigger output is a + and – terminal
instead of a 3.5mm mini jack, you can cut off the 3.5mm mini plug from one end of one
of the included trigger wires and attach its bare wires to these terminals. The trigger
plug tip is + (positive) and its sleeve – (negative).
AC Line Power Cord
Connect your sources and preamplifier before you plug in the AC cord.
The power cord supplied with your
4 DAX is an IEC type 18AWG AC cord. The AC ground potential can vary between your AC wall outlets and
the result can be an audible 60Hz (or 50Hz) hum. To help avoid this problem plug your 4 DAX into the same
AC wall outlet, power strip or line conditioner as all your other audio equipment.
Master AC Power Switch
The Master AC Power Switch is located to the right of the AC inlet. Press the side marked “0” for off; press
the side marked “I” for on. This switch will normally be left on but may be turned off if you will not be using
the 4 DAX for an extended period of time or if a lightning storm is imminent. Power amplifiers should always
be turned off before the 4 DAX master AC power switch is moved on or off because this can cause a burst of
sound that can damage your loudspeakers.
