Important Safety Precautions CAUTION SAFETY PRECAUTIONS 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.
Sub Getting Started OVERVIEW The Epos ELS Sub is an active loudspeaker. In other words, that means that it has an in-built power amplifier to boost the signal level. Therefore, there is no need for an external power amplifier to drive it. In addition, the ELS Sub 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 adjustment for this purpose.
Subwoofer Controls In the case of multi-channel system (5.1), connect a shielded cable from the sub-sonic output of your receiver and connect it to the RCA sockets on the back of the ELS Sub marked low level input. You will notice that there are two low level input sockets, marked L and R, which allows for a stereo signal.
Sub Subwoofer Controls 4. Power Switch Turns the subwoofer ‘ON’ or ‘OFF’ (When left in the ON position without a signal allows the ‘STANDBY’ feature to become active). 5. IEC Socket (Mains) Use this socket to connect to an appropriate mains socket via the IEC Power Cable supplied. 6. AC Voltage Selector Switch Please ensure the AC Voltage selector is in the correct position. (See page 2). 7.
Subwoofer Performance STEREO SYSTEMS OVER TEMPERATURE CUTOUT These tend to be difficult to integrate with conventional subwoofers because, for the most part, sub woofers are generally not designed to match them and suit 5.1 systems only. The Epos ELS Sub is different and was conceived as a means of extending the frequency response of a small pair of bookshelf speakers, rather than just producing large outputs at one particular frequency, such as 60 Hz.
Subwoofer Performance & Specifications SOUND PRESSURE LEVELS SPECIFICATIONS It is very easy to get used to high sound pressure levels as the human brain compensates for the level by effectively reducing the perceived level the ear is receiving and allows the person to become used to higher and higher levels until the pain threshold is reached. It is therefore necessary to be aware of this and avoid reaching this sublime state before serious or permanent damage is caused to ones ears.
