INSTALLATION
Rack Mounting
The Phonic ZX2 and ZX4 zone mixers are standard 1U rack
mountable mixers. An additional 4” of depth are needed be-
hind the mixer to allow room for the back panel connectors. To
avoid overheating, be sure that there is enough ventilation space
around the unit for cooling. Do not place the mixer in contact
with, or directly on top of, high temperature devices such as
power amplifiers.
Connectors
ZX2 and ZX4 zone mixers use balanced XLR jacks for paging
microphone input, unbalanced stereo RCA jacks for music input,
and balanced 3-pin phoenix/euroblock phone jacks for emergency
audio input, zone output and utility output. RJ45 jacks provide input
and output for paging and remote level control, while an RS-232
D-type 9-pin connector is provided for source link.
Impedance
The microphone input impedance is less than 2k ohms. The out-
puts of the ZX2 and ZX4 are electronically balanced with out-
put impedance lower than 120 ohms. When driving transformer
coupled loads, it may be necessary to create 600 ohms source
impedance. For this purpose, install two 247 ohm resistors in
series with pin 2 and 3.
Mains Connection
The ZX2 and ZX4 use a standard IEC receptacle and a univer-
sal mains cable to make the AC mains connection. Make sure
all units in the sound system are well grounded. For your own
safety, do not remove the ground connection within the units or
at the supply cable, or fails to make this connection at all. The
audio ground is capacitor decoupled so please isolate it from the
power ground. Do not attempt to solve ground loop problems by
disconnecting the power ground.
Safety Fuse Replacement
A safety fuse protects the unit from serious malfunction. The
fuse will blow in the event of power problems or short circuits. If
this happens, please replace it with an identical fuse only. If the
new fuse also blows right after replacement, there is likely to be
a problem with the unit. In that event, please call your nearest au-
thorized Phonic dealer for service or repair. Never use fuses that
are not rated for the unit. This may cause fire or electric shocks.
Congratulations on your purchase of the ZX2 or ZX4, two- and
four-zone mixers that are ideal for use in all manners of instal-
lations, in such venues as hotels, convention centers, theatres,
restaurants and retail outlets. They offer three stereo line inputs,
one paging microphone input with EQ and ducking depth, and an
emergency input. Two or four zone outputs provide maximum
zone separation and a mono “utility” output is also included for
areas such as restrooms and foyers. Zone and utility outputs
all have individual source selectors and level controls, while the

An emergency interface connector allows for an override control
and insert of emergency message paging. The added option
of remote volume control for each zone makes the ZX mixers a
must have for your zone mixing requirements.
