The ZA series uses a toroidal transformer based Linear
PowerSupplyandnew‘stateoftheart’PowerAmplifier
Integrated Circuits, offering unprecedented amplifier
and load protection.
This is coupled with our ‘Headroom Enhance’ circuitry
based on our core ISC error correction technology,
developed by ARX and incorporated into all our Power
Amplifiers.
It provides maximum power output levels under all AC
mains supply voltages and rated load conditions, elimi-
nating Output Stage clipping.

TheARXZA600isa6channelpoweramplifier,idealfor
any installation requiring multiple amplifier channels.
Individual pairs of channels can be switched to run as
single bridged mono channels for greater output into 8
ohm loads.
OurexclusiveAutoLinkdesignallowsall6channelstobe
linked as required.
Inserting a lead into Channel 1 input will automatically
route that signal to all the other channels as well.

However, if another lead is inserted into the Channel 3
Input,thelinkwill breakandstartagain,routingthenew
signaltochannels3,4,5,and6.Insertinganotherleadat,
say, Channel 5 will do the same.
In this way the ZA 600 can be easily and quickly config-
ured for single and multiple zones without requiring a
zone splitter.
Power Output is 100W RMS per channel/8 ohms, 125
W/4ohms, andBridged/8 ohms 250Wper channelpair
The ARX ZA 400 is an 4 channel power amplifier, ideal
for paging systems, Foreground and Background music
systems, A/V surround systems, Loudspeaker Multi-
Zoningandotherinstallationsrequiringmultipleamplifi-
erchannels. Individual pairs of channelscanbeswitched
to run as single bridged mono channels for greater
output into 8 ohm loads.
Our exclusive AutoLink design, first seen on the ARX
MultiQparametricequalizer,allowsalleightchannelsto
be linked as required.
Inserting a lead into Channel 1 input, for example, will
automatically route that signal to channels 2, 3, and 4 as
well.
However, if another lead is inserted into the Channel 3
Input,thelinkwillbreakandstart again,routing thenew
signal to channels 3 and 4.
In this way the ZA 400 can be easily and quickly config-
ured for single and multiple zones without requiring a
