WARNING

For safety reasons please read the following instructions carefully before attempting to connect
your Epos M subwoofer to the mains.

The M subwoofer is not designed for permanent external use. Being a powered product it would
be damaged by rain water or other contaminants entering into the amplifier via the vent holes and
the wooden cabinet would be damaged if soaked with water.

As with all electrical products, make sure the correct mains voltage is selected by the two way
selector switch on the rear panel marked AC Voltage Selector. If you are in any doubt, contact your
supplier for advice. As a general rule, the amplifier cannot be damaged by supplying lower
voltages than marked on the switch panel, but excessive voltage will cause the mains fuse to blow
or possibly even damage the internal circuitry (if in doubt, ask your dealer/supplier).

Two power cords are supplied as standard with the M subwoofer. These have the international
IEC connector for plugging into the amplifier panel at one end and either of two styles of plug at
the other end.

USA, Canada and Japan

The USA style plug with two flat blades should be used with the voltage selector switched to 115V
operation and a mains fuse rated at 4 Amp inserted in the pull-out drawer.

Europe

The two round pin Euro plug should be used with the AC Voltage selector switched to 230V.

Rest of World

Your distributor/dealer will ensure you have the correct cable. Please check if in doubt.

CAUTION

To reduce the risk of electric shock, do not remove the rear panel. There are no user serviceable
parts inside. Please refer all servicing to a qualified engineer.

The lightning flash with the arrowhead symbol within an equilateral triangle is intended to alert the
user to the presence of un-insulated 'dangerous voltage' within the product's enclosure that may
be of sufficient magnitude to constitute a risk of electric shock to persons.

The exclamation mark within an equilateral triangle is intended to alert the user to the presence of
important safety information featured within this instruction manual.

IMPORTANT SAFETY PRECAUTIONS

VENTILATION

Slots and openings in the cabinet are provided for ventilation and to ensure reliable operation of
the product. To protect it from overheating, these openings must not be blocked or covered.

The openings should never be blocked by placing the product on a bed, sofa, rug, or other similar
surface.

This product should not be placed in a built-in installation such as a bookcase or rack unless
proper ventilation is provided and the manufacturer's instructions have been adhered to.

SAFETY PRECAUTIONS
Read Instructions

- All the safety and operating instructions should be read before the product is

operated.

Retain Instructions

- The safety and operating instructions should be retained for future

reference.

Heed Warnings - All warnings on the product and the operating instructions should be adhered to.

Follow instructions - All operating and use instructions should be followed.

Cleaning - Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or

UNPACKING

The M subwoofer is heavy. (26Kgs/57lbs) For the sake of your health, do not try to lift or carry it
around alone. Two people are required to lift it so please be careful. Get help from a family
member or friend if this product is not installed by a professional person.

The best way to remove the speaker from the carton is to open the top of the carton, roll it over
with the flaps folded out and pull the carton off, leaving the speaker in its protective polyethylene
foam. Pull one foam frame off one at a time and lower the speaker to the floor carefully. Remove
the poly bag and keep it out of the hands of children and babies as it can cause suffocation.

GETTING STARTED

OVERVIEW

The Epos M Subwoofer is an active loudspeaker. In other words, it has an built-in power
amplifier to boost the signal level. Therefore, there is no need for an external power amplifier to
drive it. In addition, the M Subwoofer has a complex filter circuit which boosts sub-sonic
frequencies and is adjustable to allow it to be matched to different room sizes, shapes and user
requirements. The rear panel controls provide a range of adjustments for this purpose.

The M Subwoofer is designed to extend the low frequency response of both 2 channel and multi­channel systems, which each demand a very different tonal balance. This is described later, but
control adjustment and placement in the listening room is important, so please read these
instructions carefully for best results.

QUALITY

The M Subwoofer has a powerful 10" (254mm) loudspeaker driver, with enough magnet strength
and voice coil size to handle very high power levels for long periods without distress. Its cone
diaphragm is very stiff to keep distortion and colouration to a minimum. The rubber suspension
surround is smaller than normal and quite stiff, which also helps to reduce distortion and low
frequency over-hang. In short it has been designed to be more appropriate for a two channel bass
unit than a conventional subwoofer.

To further boost the fidelity of the M subwoofer, it has a very stiff cabinet with extensive internal
bracing, which is rarely found in conventional subwoofers. It has a completely separate section at
the back of the cabinet to house the amplifier, which would normally be found in professional
speakers and not in conventional subwoofers at any price. To further improve the sound quality
Epos does not use port tuning to achieve boost bass extension, which avoids 'chuffing' air
turbulence noises interfering with the fidelity of the speaker.

In short, the M subwoofer is very unusual and can be used to good effect to extend the
frequency response of a stereo system of any quality or price.

INSTALLATION AND SETUP

Having established which power cord to use, select the correct mains voltage for your region with
the selector switch on the back panel. (If in doubt, please read Page 1 again or ask your
supplying dealer for advice). If neither of the two cords supplied are correct for your mains supply
socket, do not proceed until you have contacted your dealer for advice or assistance.

Positioning the subwoofer is important if the best results are to be achieved. Place the subwoofer
where it can be connected easily to the mains power supply and to the output of the receiver or
stereo amplifier used for the rest of your system. Whilst this would normally be close to the
system, be prepared to move it around the room to gain the best results.

The Epos M Subwoofer is a ‘down-firing’ speaker that has four purpose made legs that hold it
50mm above the floor. It also has a plinth that fixes to the ends of the feet with long bolts and
covers the entire bottom of the speaker. Make sure the plinth is bolted to the cabinet with the Epos
badge at the front. The plinth helps to prevent accidental damage to the exposed driver and also
provides a stable platform for the speaker to stand on.

The mains supply can be left connected as it has a low current standby condition which is enabled
when no signal is present for a short while.
