- A mains power cord or cords to suit the country of sale.
- 4 spikes, locking nuts and spike covers.
Check the product carefully. If any items are damaged or missing, report this to your dealer as soon as possible.
We hope you enjoy the Q Acoustics experience.
For any additional info not contained within this manual, support questions and/or requests, please visit our on-line Knowledge Base Portal at www.qacoustics.co.uk/faqs
Preparation
Lift the speaker from the carton by holding the cabinet. Do not touch the driver unit or use the protective bag to lift it. The QB12 is very heavy - get assistance to lift it if necessary.
Thread the locking nut onto the spike and screw all four spikes into the threaded inserts on the subwoofer. If you have a wood or stone floor push a spike protector over each spike before turning the speaker upright. When the speaker is the right way up adjust all the spikes until the loudspeaker is level and stable.
Spikes are sharp. Exercise care! Never place a spiked loudspeaker where it can cause damage! Always move your loudspeakers by lifting them - never drag them!
Positioning
Bass frequencies are substantially omni-directional. Although this means that you can position the subwoofer almost anywhere, the stereo image will still benefit from positioning the subwoofer in line 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 too close to a wall the bass will be reinforced, therefore in some locations the bass may be boomy and indistinct.
The POWER Switch is the means of disconnecting this apparatus from the mains supply and is mounted on the control panel.
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.
All the loudspeakers may be operated close to TV monitors with no ill-effects with the exception of the Q B12 which should not be operated within 500mm of TV screens monitors or other magnetically sensitive equipment. Plasma and LCD screens are unaffected.
Controls and Connections
Controls and Connections
With this switch set to AUTO, when not in use the subwoofer shuts down to save power and switches on when it senses a signal. This can be over-ridden by switching ON.
The Phase Switch (2) changes the phase of the subwoofer so that it works in phase with the rest of the speakers in the system. Place the subwoofer more than 1 metre away from the front speakers and switch the phase between 0^ and 180^ . When the subwoofer sounds louder and fuller then it is in phase.
The Crossover Control (3) changes the pitch at which the subwoofer starts to work. It is recommended that the crossover point is set to the 'AV' setting on the dial when used with a Q Acoustics system. If you are using the subwoofer with a non Q Acoustics system then you can change the crossover point to suit your system.
The Level Control (4) increases or decreases the volume of your subwoofer in relation to the other speakers in the system. Start with the volume at 0 on the dial then turn it up slowly until you can hear it. The subwoofer should be heard as part of the overall sound and not overpower the rest of the system. There is no rule for setting the volume on your subwoofer so experiment with different music and films to set it to your tastes.
The Line Level Input-LFE (6) is Q Acoustics preferred AV connection to the amplifier.
Connect the subwoofer to the output on your AV amplifier or DVD player. Use R and L if your amplifier output is split left and right.
Multi-Channel AV System
For Stereo System connection, see next section.
Connections
For a typical AV system set-up you will need a single RCA phono interconnect. As this cable is likely to be quite long, make sure you get a good quality fully screened cable. Your Q Acoustics dealer will be happy to supply you with a suitable interconnect.
Connect the SUBWOOFER OUTPUT on the AV amplifier to the L/Mono Line input on the subwoofer, pushing the plugs firmly home to ensure a good contact.
Setting Up
Check that all system connections are properly and securely made. Ensure that the subwoofer is switched off.
Set the controls to the following default settings:
| Level | Approximately | half |
| Crossover | Fully clockwise (AV setting) | |
| Phase invert | 0° | |
| Auto on | AUTO or ON |
Plug the supplied power cord into the subwoofer and then into an AC supply socket. Switch on the power at the supply socket and then switch the POWER switch on the subwoofer to 'ON'. The Status light on the subwoofer amplifier panel will glow and the subwoofer is operational.
Check the settings on your AV amplifier to make sure that the subwoofer is set to 'ON' or 'YES'. The subwoofer level on the AV amplifier should be set at its default position or 0dB. You should already have set the speaker sizes and positions for all the other speakers in your system. If you have the option to set the crossover frequency on the other channels make sure this is set appropriately to your speakers. Finally, set the distance (or delay) setting that is correct for the subwoofer position you have chosen.
Multi-Channel AV System
Play some stereo music you are familiar with and experiment with the PHASE setting and LEVEL controls until you hear a seamless blend between the front speakers and the subwoofer. If you can hear the subwoofer standing out it's too loud!
Always bear in mind that the human ear's sensitivity to bass varies enormously with the volume level, hence the need for a wide range of programme material and sound levels.
Many Home Theatre amplifiers have distance settings which build in a time delay depending on the distance of the speaker from the optimum listening position; the sweet spot. The location of the subwoofer is one of the most important aspects of any Home Theatre system, therefore getting these settings correct will give a significant improvement to the system's overall performance.
Do not adjust to more than +/-0.5m from the original measured distance. If it has not been possible to discern any improvement in the tone, try swapping the PHASE switch position on the Q B12 and repeat the exercise. Then re-check the sound with some stereo music again to make sure an improvement has been noticed.
If the Q B12 is subsequently moved relative to the other speakers reset the amplifier's subwoofer distance setting to the new value and repeat the exercise. Once you are happy the optimum setting has been achieved the sound should be full, warm and integrated, with no individual speaker being dominant.
If the subwoofer is triggered on by appliances switching on and off, re-route the input signal cable before taking further measures.
Multi-Channel AV System
When running loudspeaker cables be especially careful not to run them across open floor areas where they could be a source of danger. Run loudspeaker cables around room boundaries whenever possible. Line level signal cables should be run away from mains cables. Never run line level signal cables parallel to power cables especially on long runs.
If the subwoofer is triggered on by appliances switching on and off, re-route the input signal cable before taking further measures.
Placement: 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 bookshelf speakers wherever they are used in the system. The floorstanding should be set to 'Large'. The subwoofer option should be enabled (set to 'ON' or 'YES')
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 speakers
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!
Stereo System
Connect a good quality stereo RCA phono lead to the L and R inputs on the Q B12 and connect the other end to the PRE OUT sockets on the rear of the amplifier. The subwoofer will automatically add the L and R signals together so that no information is missed.
If you wish to use two subwoofer then you can run a single RCA phono cable to each subwoofer and thus have a stereo subwoofer system. Ensure that the L output on the amplifier goes to the left hand side subwoofer and R to the right hand side to preserve the stereo image of the main speakers. The subwoofer will need to be placed close to their respective main speakers and the set-up will need to be done separately for each subwoofer.
Stereo System
Setting Up
Check that all system connections are properly and securely made. Ensure that the subwoofer is switched off. Set the controls to the following default settings:
Level Approximately half
Crossover Minimum (50Hz) for large floorstanders and halfway (100Hz) for bookshelf or small speakers
Phase invert 0^
Auto on AUTO or ON
Plug the supplied power cord into the subwoofer and then into the AC supply socket. Switch on the power at the supply socket and then switch the POWER switch on the subwoofer to 'ON'. The Status light on the subwoofer amplifier panel will glow and the subwoofer is operational.
Play some music you are familiar with and experiment with the PHASE setting and LEVEL control until you hear a good blend between the front speakers and the subwoofer. If you can hear the subwoofer standing out it's too loud!
Always bear in mind that the human ear's sensitivity to bass varies enormously with the volume level, hence the need for a wide range of programme material and sound levels. Once you are happy with the sound you can then fine tune the performance by using the remaining controls.
CROSSOVER: The crossover control determines the frequency above which your subwoofer output begins to diminish. This should be set so that it corresponds with the frequency your main speakers begin to produce a strong output by themselves. The adjustment allows for a smooth handing over between subwoofer and main speaker output. If this setting is too low there will be a 'hole' in the sound where certain frequencies are weak, conversely if it is too high there will be an exaggeration of certain frequencies producing an overpowering bass. You can get an idea of the correct setting from your main speakers' specification sheet. Look for the lowest frequency that the speaker produces (the "-3dB point") under the "Frequency Response" heading. Room positioning has a dramatic effect on low frequency reproduction of both the subwoofer and your main speakers so don't be worried if you find you require a setting which does not correlate with the specified low frequency point of your main speakers.
Aftercare
Cabinet Care
Clean cabinets only with a lightly dampened cloth. Do not use solvent based cleaning materials. Never use abrasives of any kind.
The cabinet surfaces will usually only require light dusting. Should an aerosol or other cleaner be used, apply the cleaner onto the cloth first and not directly onto the product. Test a small area first, as some cleaning products may damage the finish. Avoid products that are abrasive, or contain acid or alkaline agents. Do not use any cleaning materials on the drive units and avoid touching them as damage may result.
Grilles
Grilles should only be cleaned using a soft brush when necessary.
Drive Units
Do not touch the drive units as they are easily damaged when exposed.
