Operation Manual

Two 4 ohm subwoofers connected (2 ohm load)

Four 4 ohm subwoofers connected (1 ohm load)

NOTE!

The amplifier is 1 ohm stable. This means that you

can connect subwoofers in various connections, in

parallel or in series, as long as the resulting

impedance is not less than1 ohm.

If you have subwoofers with dual 4 ohm voice coils,

connect the coils in parallel to get more power from

the amplifier.

Speaker wiring RA10

RA10 is a mono amplifier made for use with subwoofers

only. The amplifier has two output connectors. These

are internally connected in parallel and are doubled

for easier connection when you have more than one

subwoofer. It is not possible to connect in bridge

mode between the speaker terminals.

The typical setting is around 60 – 80 Hz.

The subsonic filter should be in position IN.
