d) Select a live source component (CD Player/
Tuner/Tape/Disc Recorder/Turntable/Video
Player) on the system’s integrated amplifier or
pre-amplifier.
e) Audio should now be heard when the source
component is played.
a) Turn the Integrated Amplifier or pre-amplifier
volume control to minimum.
b) Press power switch.The LED power indicator
will light up.
c) Without playing any CD Player/Tuner/Tape/
Disc Recorder/Turntable/Video Player, turn
the volume control knob slowly clockwise to
around 30%.You Should only hear a faint hiss.
4Operation
Ensure that your unit is switched off and that the vol-
ume control on the pre-amplifier or integrated ampli-
fier is at its minimum.
Please note that your Exposure 3010S Power Ampli-
fier may take up to 48 hours to “run-in” before reach-
ing its optimal performance. Each subsequent “run-in”
will then take about 20 minutes.
The Exposure 3010S Power Amplifier has a heat sen-
sor which will automatically switch off the power am-
plifier section when an abnormally high temperature
is reached.To reset the output, switch off the amplifier
and allow to cool for 10 to 15 minutes.
a) Connect left and right loudspeakers to corresponding left and right speaker outputs amplifier.
b) Connect (+) terminal of the loudspeaker to (+) terminal of the amplifier.
c) Connect (-) terminal of the loudspeaker to (-) terminal of the amplifier.
Bi-wiring
Bi-wiring may provide a useful gain in subjective performance. Should you
choose this option, please refer to the “Extended Set-Up” section overleaf
for detailed instructions.

Your Exposure 3010S Power Amplifier is equipped with a pair of RCA phono input sockets.
The Exposure 3010S Power Amplifier : Back View
a) Connect cables from RCA Phono inputs of power amp to the PRE-OUT sockets of
pre-amp/integrated amp.
b) Ensure left and right channels are connected appropriately. (Right channel are marked
in red)

Exposure 3010S Power Amplifier Extended Set-Up
Mono Mode
When selected to the Mono mode at the back of the Exposure 3010S Power Amplifier, both channels
are combined into one single channel with the inputs in parallel. This allows each channel to
have the Power supply all to itself for better separation.
Note: In Mono mode, the left input socket is only used. You need to purchase another Exposure Power
Amplifier to operate in stereo. See diagram for connecting a pair of loudspeakers in mono mode.
Bi-wiring
The Exposure 3010S Power Amplifier is fitted with two sets of 4mm loudspeaker connection output sock-
ets for bi-wired connections of loudspeakers. Another pair of speaker wires is required for this operation
for each loudspeaker.
1. Ensure that the links at the speaker terminals between the high frequency and the low frequency
are removed on both loudspeakers.
2. Follow the diagram below for connecting a pair of loudspeakers in bi-wiring mode.
Please refer to the manufacturer of your loudspeakers for advice on the practicality and potential
benefits of bi-wiring.
Bi-amping Mode
The Exposure 3010S Integrated Amplifier can also be used as a pre-amplifier for the Exposure 3010S
Power Amplifier.
The Power Amplifier section of the Exposure 3010S Integrated Amplifier will still be operational, and can
be used in conjunction with the Exposure 3010S Power Amplifier in Stereo mode to provide bi-amping
capabilities for suitable loudspeakers:
1. Check your loudspeaker user manual for the wiring connections.
2. Connect the pre-out sockets on the Exposure 3010S Integrated Amplifier to the input sockets of the
Exposure 3010S Power Amplifier.
3. See diagram for connecting a pair of loudspeakers in bi-amp mode.
Your dealer or local distributor will be able to offer further advice.
Operational Modes
The Exposure 3010S Power Amplifier can be operated in one of three different modes.These are:
Stereo Mode (Factory Default)
The Exposure 3010S Power Amplifier by default is selected to Stereo mode at the back of the unit.
It operates as a conventional stereo amplifier with each channel fully independent of the other.
The majority of 3010S Power Amplifier applications will employ this mode.
Speaker Cable Compatibility
While the Exposure 3010S Power Amplifier is compatible with most types of loudspeaker cables, the
type of cables used can influence the sonic performance of your system. Please ask your Exposure dealer
for advice on loudspeaker cable compatibility and how to get the best from your Exposure 3010S Power
Amplifier.
Note: The Exposure 3010S Power Amplifier is internally protected against damage from short circuits.
However, no such protection is infallible, and damage may occur if positive and negative speaker cables are
inadvertently connected together.

Loudspeaker Compatibility
Although the Exposure 3010S Power Amplifier is able to drive almost any loudspeaker system, the best
results will most likely be achieved with speakers rated at 8 Ohms. For loudspeakers rated below 4 Ohms,
the use of two Exposure 3010S Power Amplifier operating in Mono mode should be considered. See sec-
tion on Operational Modes for further details.
