Caution Marking Explanation

The lightning flash with 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 point within an equilateral triangle is intended to alert the

user to the presence of important operating and maintenance (servicing)

instructions in the literature accompanying the appliance.

other apparatus (including amplifiers) that produce heat. 9 Do not defeat the safety purpose of the grounding-type plug. A grounding type plug has two blades and a third grounding prong. The third prong is provided for your safety. If the provided plug does not fit into your outlet, consult and electrician for replacement of the obsolete outlet. 10 Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.

Design Safety This apparatus is supplied with a detachable mains cord. For 240V operation a 3.15/S/2, 5A/S/3, 5A/S/5 fuse is fitted in the socket, for 120V operation a 6.3A/S/2, 9A/S/3, 9A/S/5 fuse is fitted. Should the fuse need to be replaced use a similar rated fuse approved to ASTA or BSI 362 standards. Do not use without the fuse cover in place. Replacement fuse covers are available from your distributor.

as explosions by the latest movie soundtracks are delivered with visceral slam. Meanwhile, the classic REL approach of using both High Level + .1/LFE permits richly natural bass to wash through less ambitious tracks allowing for greater enjoyment of the movie experience, no matter the scale of the movie. 212SE reaffirms REL’s relentless pursuit of delivering the best and most varied offerings among subwoofer manufacturers.

The dedicated LFE input meets the tough specification laid down for digital 3/2.1 channels, usually known as 5.1. The output is nominally flat from 35 Hz – 90 Hz. It has a dedicated input level control which enables users to set the LFE level independently of the processor. This is important because not all processors offer control over this significant parameter. The LFE channel is frequently output at 10 dB higher levels than the other channels.

.1 Input: This requires a phono-to-phono cable and is a dedicated true .1 channel. This circuit therefore eliminates the normal Natural RollOff™ Crossover and passes the .1 low-level signal through with only the required 120Hz fourth-order filter. Low-Level Input: These left and right phono inputs allow for conventional connection from a preamplifier and should be used in the rare event that a high-level connection proves incompatible. Connect as shown below.

amplifier because the REL’s amplifier input impedance is 150,000 ohms, in effect producing NO additional load on the rest of your system. • The standard high-level hook up procedure is: attach the red wire to the amplifier’s right positive speaker output terminal; attach the yellow wire to the amplifier’s left positive speaker output terminal; attach the black wire to whichever of the amplifier’s ground output terminals is convenient; plug the Speakon® connector into the Sub-Bass System’s high-level input.

When connecting to a home cinema system where there is a .1/LFE channel output, connect a single phono cable between the sub output of the processor/receiver and the .1/LFE input jack on the REL. 1 Positioning: The optimal position for a REL is in one of the corners behind the main speakers.

been reached, subtle changes to volume and crossover can be accomplished to provide the last bit of complete and seamless integration. With that, set-up is complete. Hint: There may be a tendency to set the crossover point too high and the volume of the Sub-Bass System too low when first learning how to integrate a REL with the system, the fear being one of overwhelming the main speakers with bass. But in doing so, the resulting set-up will be lacking in bass depth and dynamics.

time – important in a unit designed for an exceptionally long working life. These amplifiers are designed to withstand reasonable abuse and overloads. If in doubt, please contact your dealer. We believe that the importance of the electronics, cabinet and drivers being designed to work in harmony is paramount. This approach allows the 212SE Sub-Bass Systems to achieve the highest possible level of fidelity. Overload Protection All REL Sub-Bass Systems are designed as true sub bass speakers.

Note: Due to variations in program material, it is impossible to produce a perfectly reliable standby circuit. Bass rich music or effects will consistently trigger our standby circuit whilst content that is low in volume and possesses little or no bass cannot be relied upon to trip the standby function. Alternatively, the user has the option to leave the unit in the normal operation mode at all times by selecting the “ALWAYS ON” position of the power mode switch.

After initial setup, if you wish to employ the standby mode, simply move the power mode switch into the up position to “STANDBY”.
