Turn On Options Switch
For your convenience, there are three ways the Zcd can be turned on and off.
Manual
: When the Turn On Options switch is set to Manual you may use its front panel
Power button or the remote control’s On and Off buttons.
AC
: When the Turn On Options switch is set to AC the Zcd will never turn off even if you
press its Power button or press the remote’s On and Off buttons.
12V
: When the Turn On Options switch is set to the 12V position the Zcd is turned on and
off with an ex9 V to + 12 V DC voltage from your preamp or system controller.
When the external voltage ceases the Zcd will turn off immediately.
Note:
When the Turn On Options switch is set to 12V or AC the front panel Power button
and remote control On and Off buttons are disabled.
12V In Jack
The Zcd 12V input uses a mono 3.5mm mini jack. To trigger the Zcd On and off, insert the
trigger wire plug into this jack and plug the other end into your preamp or system controller’s
12V output jack. When the Turn On Options switch is set to 12V the Zcd will turn on and off
automatically when your preamp or system controller is turned on or off. The Zcd trigger circuit
draws a negligible 15 mA.
Note:
If the controller’s trigger output is a + and - terminal, you can cut the plug off one end of
the included trigger wire and attach the bare wires to these terminals. If the trigger voltage
source is DC, the trigger plug tip must be + (positive) and its sleeve – (negative). The wire with
the stripe on it corresponds to the plug’s tip and the unmarked wire corresponds to the sleeve of
the plug.
12V Out Jack
The 12V Out Jack will supply 12 volts whenever the Zcd is turned on. You can use this output
to trigger a power amplifier such as the Parasound Zamp v.3 to turn on automatically. This is
particularly useful if you are not using a preamp and the Zcd is connected directly to a power
amp. This output can supply up to 40ma, far more than needed to trigger a Parasound power
amplifier on and off.
RS-232 Control Jack
This DB9 serial port permits the Zcd to be controlled by home automation and control systems
such as Crestron®, AMX®, Control4®, Niles® and Elan®. When the Zcd is connected to such a
device, it can be controlled from keypads or touch-screen panels throughout your house. The
capabilities of such connections, and the programming and interfacing needed will depend on
the automation system you select. Consult your Parasound dealer or custom installer for more
information regarding interfacing an external control system to your Zcd. The complete Zcd RS-
232 protocol can be found at:

AC Line Cord
Connect the AC cord only after you have connected all of the other wires. The power cord
supplied with your Zcd is an IEC standard AC cord. If possible, plug your Zcd into the same AC
outlet that your accompanying audio components (particularly your preamp and power amplifiers)
are plugged into. If different AC outlets are used the ground potential may be higher or lower
between the AC outlets, resulting in audible hum in the system.
