REAR PANEL CONNECTIONS AND CONTROLS continued

Zone 1 2 3 4 Switch

You can ignore this switch if you are using a single Zpre2 in your system.
The Zone switch and remote control handset can select four discrete IR codes 

to control up to four Zpre2s in four zones independently with a single remote 

handset or IR-based system controller.
The Zone switch and remote handset factory default settings are both 1. If you 

move the Zone switch to another number you’ll also have to reprogram the 

remote handset with the same zone number (see Remote Control).  

Note:

 The Zone switch selects a new IR zone code only when the Zpre2 is turned off. If you 

Note:

Note:

move the Zone switch to select a new IR zone code while the Zpre2 is turned on, you’ll need to 

turn it off for a few seconds, then on again.

Ext (External) Remote Jack 

Your Zpre2 accepts the infrared signal of any popular infrared repeater system to facilitate 

remote control operation from another room or when it 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:

 Unlike Parasound Surround Controllers, the Zpre2 Ext Remote input does not require an 

Note:

Note:

amplified IR connecting block.

Automatic Turn On Options

For convenience the Zpre2 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 Zpre2 front panel Power 

button is disabled so that on/off is determined solely by the triggering system master controller.

RS-232 Control Jack

This is a DB9 serial port which accepts commands from your system controller (“write”) and feeds 

back status to be displayed (“read”). The following can be controlled and displayed:
 

- Power on 

 

- Input selected

 

- Volume was adjusted via RS-232

 

- Mute on

Note:

 The RS-232 will feedback when volume level is changed by the RS-232, but  not if it is 

Note:

Note:

adjusted  with the front panel knob or remote control handset. The RS-232 

“read” does not display the actual level because it uses an analog volume 

control which cannot show its setting. In most instances this won’t be an issue, 

since volume level is immediately heard as satisfactory, too high or too low.
“Write” and “Read” RS-232 codes for the Zpre2 are available at our website, 

www.parasound.com. 

Auto - Man (Manual) Turn On Switch

Auto position

When the Auto - Man switch is set to its Auto position, the Zpre2 is turned on and off with an 

ex9 V to + 12 V voltage from your controller or preamplifier. When the external voltage 

ceases the Zpre2 will turn off immediately.

Note:

 The Auto switch position disables the front panel Power button.

Note:

Note:

Man Position

When the Auto - Man switch is in its Man (manual) position, the auto turn on function is 

disabled and the Zpre2 must be turned on and off manually with the Power button on its front 

panel or its remote control.
