14. Power Cable Receptacle
This is a standard IEC power cable receptacle. Plug the power
cable in here and connect the other end of the cable to an
appropriate AC mains power supply.
15. 24VDC Control
This terminal black input accepts an external 24 VDC regardless
of the position of the positive and negative poles. It will activate
the emergency function, which will route the external emergency
message to all zone and utility outputs. It provides an override
control for emergency use.
16. Audio Input
This 1/4" input jack accepts input by balanced or unbalanced
phone plugs. This input works in conjunction with the 24 VDC
CONTROL. When the circuit is activated by a 24 VDC power
supply all other audio input sources will be terminated and
whichever audio source is connected to the emergency audio
will be routed to all zone and utility outputs.
17. Utility Output
This is a standard line-level 1/4" phone jack output for balanced
or unbalanced connections.
18. Zone Outputs
These are standard balanced line-level 1/4" phone jack outputs.
The zone outputs include left (L) and right (R) channel outputs
(zone 4 on the ZX4 only has a mono output channel). There is
also a subwoofer (SUB) output included for better low frequency
performance (ZX2 only). When operating in mono mode, use
the left channel.
19. Remote Level Control
This socket allows for the connection of external volume control
devices to remotely control music. Each remote socket controls
up to two zones. When the REMOTE connection is not made, the
output level of each zone will be according to the level selected
on the mixer. Please use a 10k ohm potentiometer as the remote
level controller.

20. Source Input
These are unbalanced line-level stereo RCA inputs. There are
three stereo music input sources. Each includes a gain control
with a range of -10 dB to +20 dB.
21. Source Link
The source link is an RS-232 D-type 9-pin connector that
distributes the three source inputs to the next compatible zone
mixer in the series. It also functions to receive the source input
from a ZX2 or ZX4 zone mixer. This function allows the source
inputs from one Phonic zone mixer to be used for many other
Phonic zone mixers while simplifying wiring schemes.
22. Paging Control
This RJ45 jack is used to connect a paging control to the ZX2 or
ZX4 mixers. The ZX2 and ZX4's paging control is optional.
23. Paging Microphone Input
This is a balanced XLR jack that is used to connect the output of
a paging microphone to the mixer. It includes a gain control with
a range of +15 dB to -15 dB. The paging microphone connects
to the mixer through an XLR input and the paging control. The
paging control allows users to select the destination of the
microphone's signal. The following is a diagram detailing how to
make the connection.
