Ext (External) Remote Control
Input Jack
Your Ztuner v.2 accepts the infrared signal of any popular infrared repeater system to facilitate
remote control operation from another room or when your tuner is installed within a closed
cabinet. This connector is a
1
⁄
8
" (3.5 mm) two conductor mini jack; its center conductor (plug tip)
is +, its outer conductor (plug sleeve) is - .
Note
: this input does not require an amplified IR connecting block.
Loop Jack
A Loop out jack is provided as a convenience so you may pass along or “daisy-chain” the
incoming IR repeater signal to another remote-controlled component.
Automatic Turn On Options
For convenience the Ztuner v.2 can be triggered to turn on automatically when a suitable voltage
is applied to its 12V In (input) jack. When automatic turn on is selected the Ztuner v.2 front panel
power button, IR remote power and RS-232 power commands are disabled so that on/off is
determined solely by the triggering preamp or controller.
Man (Manual) Auto Turn On Switch
Man Position
When the Man Auto switch is in its Man (manual) position, the auto turn on function is disabled
and the Ztuner v.2 must be turned on and off manually with the Power button on its front panel
or by the remote handset.
Auto position
When the Man Auto switch is set to its Auto position, the Ztuner v.2 is turned on and off with
an ex9 to +12 volts from your controller or preamplifier. When the external voltage
ceases the Ztuner v.2 will turn off immediately. The Auto switch position disables the front panel
Power button, the remote’s On and Off buttons and the RS-232 commands for on and off.
12V In Connection
The Ztuner v.2 12V input uses a 2.5 mm sub-mini jack. To trigger the Ztuner v.2, plug one end
of the provided cord into this jack and the other end into the source component’s trigger output.
Some components may use a 3.5 mm trigger output jack, so we have also included a trigger
wire with a 3.5mm plug at one end and a 2.5mm plug at the other end.
If the control component’s trigger output is a + and - terminal, you can cut the 2.5 mm plug off
one end of the included trigger wire and attach the bare wires to these terminals. The lead with
the white stripe on it corresponds to the plug’s tip and the unmarked lead corresponds to the
sleeve of the plug.
Note
: If the trigger voltage source is DC, the trigger plug tip must be + (positive) and its
sleeve - (negative). The Ztuner v.2 trigger current draw is a negligible 15 mA.
