If not, consider placing the TV on a cabinet with the 2000Ci on a secure shelf immediately below the TV.

Before connecting the subwoofer please make sure that all the electronics in your system are switched off at the mains. The subwoofer is set to the voltage in your area. If you move to an area with a different voltage, be sure to set the voltage selector to the right setting before connection to the mains supply! Positioning the Subwoofer Bass frequencies are substantially omni directional. Although this means that you can position the subwoofer almost anywhere, the stereo image will still benefit by positioning the subwoofer level with the front loudspeakers and as central to the listening position as possible. This may not be feasible in a multichannel system. If you place the subwoofer close to a wall the bass will be re-enforced therefore in some locations the bass may be boomy and indistinct. The subwoofer should be positioned close to a mains power source. Do not use extension cables. Purchase a longer power cord if necessary. The MAINS ON/OFF switch is the means of disconnecting this apparatus from the mains and is mounted on the rear panel. There should be ample free space between the rear of the cabinet and any wall or other object to allow free unrestricted access to this switch. When positioning the subwoofer ensure the floor is sound with no loose floorboards etc. The air movement from the subwoofer at high volumes is substantial - do not place it close to soft furnishings or objects that may rattle. Do not place objects of any kind on the unit. VOLTAGE LINE RIGHT LEFT OUT CHAIN RIGHT LEFT /MONO HIGH LEVEL110V-1 20V 60Hz 220V-2 40V 50Hz

SUB Above is the Dolby Labs recommended layout for 7.1systems.The 6.1 layout is the same except a single central speaker replaces the two back units. The 5.1 layout has no back speakersPlacement: The Front and Centre speakers should be in line. If this is not possible, consult your processor manual for guidance on adjusting relative centre/front delay times. If you have a 5.1 system, the listening seat can be closer to the rear wall. As always, be prepared to experiment.Bass Management: AV processors offer the choice of ‘Large’ or ‘Small’ for the speakers. If you choose ‘Large’ the speaker receives the full frequency. Choose ‘Small’ and the bass is sent to the Subwoofer. We recommend you choose ’Small’ for the 2000Ci and the 2010i and 2020i wherever they are used in the system. The 2050i should be set to ‘Large’. The subwoofer option should be enabled (set to ‘ON’ or ‘YES’)Levels: When the basic system parameters have been established, put your processor into the ‘setup’ routine. Set up each individual speaker so that the level is the same at the listening position as all the others. If your processor enables you to adjust the delay times, follow the instructions closely as this will profoundly affect the final result. When you play a movie you may think the rear channels are too soft - they aren’t! You may however have to adjust the subwoofer level both at the processor and at the subwoofer. Once set, do not re-adjust these levels.LFE: The LFE channel sends all the bass sound effects to the subwoofer. If speakers are set to ‘Small’ , system bass from those channels is also sent to the subwoofer. If you play the system at extreme levels and/or have the subwoofer level set too high you may overdrive the subwoofer with unpleasant sonic results. If this occurs, reduce the level immediately.Phase: If your speakers are incorrectly wired the bass will be blurred and thin. In this case, check the wiring carefully. If your speaker wire has a tracer along one core, consistently use the striped core to connect all the positive (RED) terminals. In this way the system will always be in phase.Always follow the instructions in your AV processor manual!Cabinet Care Q Acoustics loudspeakers are warranted free of defects in materials and workmanship as follows: Clean cabinets with a barely damp cloth.
