Introduction
M&K Sound in-wall subwoofer IW28S and amplifier VA500 form an integrated system, designed for easy in-wall
installation.
The amplifier is especially designed to power the IW28S, and cannot be used in combination with any other
products.
The VA500 amplifier features a specially designed three-position EQ switch located on the amplifier front panel,
designed to tune the response of the IW28S subwoofer for the most accurate bass performance in different posi-
tions.
Connecting the VA500 Amplifier
Adjacent to the AC power cord receptacle on the back of the amplifier you will find a voltage selector switch pre-
set at the factory for the proper local voltage.
Always check to make sure that your subwoofer is set to your country’s voltage.
If the input voltage needs to be changed, the correct fuse value must be inserted in the fuse holder next to the
AC socket.
(DIFFERENT FUSE VALUES ARE INCLUDED IN THE ACCESSORY PACK)
100-120 Volt T10AL/250 Volt – 220 Volt T6AL/250 Volt.
(If you have questions about this, contact your M&K Sound dealer)
The VA500 amplifier is provided with a detachable power cord, ALWAYS attach the cord to the subwoofer first,
BEFORE plugging it into the AC wall socket. Do NOT use “switched” power outlet found on the back of some
receivers, processors and amplifiers.
Subwoofer Line-Level In Connection
The VA500 amplifier features phono connectors for
line level input.
Use the line-level subwoofer output labeled “Sub”,
“Sub Out”, “SW”, “LFE” from your surround receiver
or processor.
When connecting subwoofer signal from receiver or
processor to the amplifier, use only Left Mono phono
input on amplifier for correct control of the amplifi-
er’s auto on/off functions.
If using “Y-splitter” phono connector, use Left and
Right inputs.
The phono outputs are not affected by the crossover,
and operate as sub “signal throughput only”.
Speaker Output Connection to Subwoofer
Connect speaker cable between the subwoofer’s push
terminals and the binding posts on the rear of the
amplifier.
The subwoofer’s push terminals accept wire thickness
up to 5 mm /AWG 6 for wiring to amplifier.
The amplifier binding posts accept banana plugs,
spade connectors or “stripped” cable.
In surround system setup, it is important to wire
all speakers correctly for proper phase. It is recom-
mended to use speaker cable with wires marked for
positive
and negative leads, for easy visual check of
connection.
