Q Acoustics 2000i Series
Introduction
The Q Acoustics 2000i series is a range of loudspeakers designed to meet the highest expectations of dedicated 2-channel audiophiles and discerning movie enthusiasts. The range comprises:
2010i: Compact Bookshelf speaker with a 100 mm bass driver.
2020i: Bookshelf speaker with a 125 mm bass driver.
2050i: Floorstander with two 165 mm bass drivers
2000Ci: Centre channel with 2 x 100 mm bass drivers, which can be wall mounted if required.
2070Si: 140 Watt active subwoofer with a 2 x 170 mm driver and signal sensing for automatic power on/off.
The 2020i and 2050i speakers are both bi-wireable. All the loudspeakers may be operated close to TV monitors with no ill-effects with the exception of the 2070Si, which should not be operated within 500mm of TV screens monitors or other magnetically sensitive equipment. Plasma and LCD screens are unaffected.
Before making any connections to your loudspeakers make sure that all active units in your system are switched off at the mains.
When switching on your sound system or changing input sources, set the main volume control at a low level. Turn up the level gradually.
NEVER play your sound system at full volume. The position of the volume control is deceptive and does not indicate the power level of the system. Using very high volume settings may damage your hearing.
DO NOT connect your loudspeaker terminals to the mains supply.
EN
DO NOT expose your loudspeakers to excessive cold, heat, humidity or sunlight.
If you play your loudspeakers without their grilles on, be careful to protect the drive units from damage.
DO NOT use makeshift stands. Fit the Q-Acoustics dedicated stand according to the instructions and using any fixings provided. Your dealer will advise you.
DO NOT dismantle the loudspeaker. You will invalidate the warranty.
Unpackingyourloudspeakers
Unpack the speakers fully. Lift the speakers from the cartons by holding the cabinets. Do not use the protective bags to lift them. The 2050i and 2070Si are heavy - get assistance to lift them if necessary.
When manoeuvring loudspeakers, do not drag them across the floor as this may cause damage - lift them before moving them.
In the carton you will find: The loudspeaker/s and this product manual.
In addition the packing for the following models contains:
2050i: A set of floor spikes and spike covers for each speaker. An Allen key to adjust the spikes once fitted.
2070Si: A power cord suitable for the mains supply in your area, 2 x Right angled RCA / Phono cables and an AV Setup CD.
Check the product carefully. If any items are damaged or missing, report this to your dealer as soon as possible.
Retain the packing for future transport. If you dispose of the packing, please do so following all recycling regulations in your area.
Preparation
Fitting the Floorstand Spikes2050i
Thread the spikes fitted with locking nuts half way into the base and return the loudspeaker to the upright position. (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, insert the Allen key into each spike from the top and adjust all the spikes in and out until the loudspeaker is level and stable.
EN
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!
Foam Bung
The 2000i series speakers are rear ported and designed to work best with some space behind them i.e. 200mm or so away from a wall. If you position your speakers close to a wall/ corner then the foam bungs should be inserted into the rear ports or there could be too much bass. The 2070Si subwoofer bass is adjusted using the level controls.
Ensure the bungs are fitted snugly into the port without inserting them too far. You will find the level of bass is reduced but definition and bass extension is increased. Experiment to see what you prefer and try making small changes to the position of the speaker to optimise the final result.
Positioning Passive Loudspeakers
EN
Dolby and the double-D symbol are
trade marks of Dolby Laboratories.
2050i
The 2050i loudspeakers should be positioned at least 200mm from a back wall and 500mm from the side walls. Placing the speakers closer to the wall will increase bass but could cause the sound to boom and lack precision and detail. The speakers should be 2m - 4m apart and central to the seated listener. Turning the speakers slightly inwards will sharpen a stereo image but may cause narrowing of the sound source.

2010iand2020i
The 2010i and 2020i are ideally mounted on Q-Acoustics floor stands or wall mounted. If you are stand mounting, a simple guide is that the treble unit should be at ear level to a seated listener. Wall mounted speakers may be mounted slighter higher with the speaker angled down. Stand mounted speakers should be treated as floorstanding speakers except that the speaker may be placed a little closer to the back wall. Shelf mounting is also possible.
An optional bracket designed specifically to wall mount the Q Acoustics 2010i, 2020i and 2000Ci is available from your dealer. Floor stands for the 2010i and 2020i are also available.
Be prepared to experiment to find the best setup for your taste in your particular listening room.
Effectsloudspeakers
2000Ci
The 2000Ci is designed to be operated close to a TV screen and central to it. It should be placed immediately above or below the screen. If you are using a regular TV set, make sure that the TV is capable of adequately supporting the speaker and has a level top. If not, consider placing the TV on a cabinet with the 2000Ci on a secure shelf immediately below the TV.
If you have a Plasma or LCD monitor, mount the 2000Ci to the wall or other suitable surface immediately above or below the
screen using the Q-Acoustics Wall Bracket.
SurroundSpeakers
400mm
There are recommendations from Dolby labs for 5.1
effects speakers.
Surround speakers should be mounted on either side
of the listener, slightly behind the listening position. The speakers should be sited facing inward either mounted on the side walls of the room or if the room is large, on high stands and with their centres above ear level to a seated listener.
Connecting Passive Loudspeakers
EN
Terminals and Connectors
The 2020i and 2050i are bi-wireable. A bi-wireable crossover has four terminals. The upper pair of terminals connects to the treble (HF) speaker and the lower pair to the bass (LF) speaker/s. As supplied the crossovers are fitted with removable links to connect the terminal pairs. This permits you to connect the loudspeaker conventionally using one pair of cables or in bi-wired mode with two pairs.
The 2010i and 2000Ci have standard two terminal crossovers.

Loudspeaker Cables
Specialist loudspeaker cables will offer a higher standard of reproduction than general purpose ‘bell’ or ‘zip’ wire. Use cable with generous amounts of copper for the front and centre channels. Thin cables reduce the bass and restrict the dynamic range. Surround (rear) channels are less critical.
Speaker cable has a stripe or tracer along one core. By convention
this is connected to the positive terminals. The cables connecting
the amplifier to the front loudspeakers should ideally be the same |
|
length. Never join cables - use complete lengths. |
7mm |
|
|
Preparing Cables |
|
Split the cable to a depth of about 40 mm.
Bare the wire to a depth of 10mm and twist 30mm the ends to gather any stray wires. Crop
the cable leaving 7mm of bare wire exposed.
Connecting a Terminal
Unscrew the terminal anticlockwise to |
Tight |
Loose |
|
expose the mounting hole in the base of |

the terminal column. |
|
|
Insert the bare end of the cable into the hole. Re-tighten the terminal fully hand tight. Make sure there are no stray wires which could touch adjacent terminals.
In the EU it is against safety regulations to use 4mm loudspeaker plugs.

Preliminaries
Unpack the subwoofer following the guidelines given earlier. 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.
2070Si Subwoofer - Operation
Setting Up and Use
Auto Power On: This feature enables you to switch the main system on and off without having to remember to switch the subwoofer on and off as well.
If there is no signal input, after a few minutes the subwoofer will automatically power down into Standby mode. This is indicated by the POWER light on the rear panel changing to red. As soon as the subwoofer senses an input it will automatically switch into operational mode and the power light will again glow green. Some types of music and some TV channels have very little low frequency information in the audio signal in which case the subwoofer may not automatically switch out of standby even though sound is coming from the other speakers in the system. If this happens then the threshold can be adjusted to make the unit more sensitive by setting the auto-on sensitivity to HIGH. Under some circumstances however this setting may make the sub-woofer stay on at all times, this is due to the small amount of noise which will normally be present from the main system amplifier. This noise should disappear when the amplifier is set to standby, thus allowing the subwoofer to turn off again. If the sub-woofer remains on even when the main amplifier is turned off then we recommend you leave the sensitivity switch at MED, the loss of bass will be almost undetectable due to the characteristic response of human ears.
If the level of noise produced by the amplifier is higher than normal, or the connection cables are picking up hum from nearby power cables, the sub-woofer may remain on even when no sound is playing. If hum is noticeable from the subwoofer then you should try moving the cables to reduce the hum pick-up or try a different cable/s. In circumstances where
EN
the problem cannot be easily remedied we recommend trying the LOW setting of the sensitivity switch to see if that allows the sub-woofer to enter standby.
Although the subwoofer can be safely left in standby mode indefinitely, if you are going to be absent from home for a long period, we advise that the unit is switched off at the ON/OFF switch.
The 2070Si Subwoofer also has a fail safe heat protection system. If the amplifier overheats it will shut down momentarily and then resume operation. If this occurs check that the ventilation holes on the control panel are not covered and that the sub-woofer is not placed too close to a source of heat such as a radiator.
Using Multiple Subwoofers: Your 2070Si sub-woofer includes a Line output connection called “Chain out”. In systems where more than one sub-woofer is used this allows the signal to be daisy chained to another one or more sub-woofers. This is just a convenience feature which is an alternative to using a “Y-Adaptor” at the amplifier output. Please note that the signal is a straight pass-through and so all sub-woofers must be setup independently using their controls as normal.
The following section is divided between home cinema installation and standard stereo installation. Please refer to the relevant section for your system.
Connecting the 2070Si
Multi-Channel AV System
Connections
Standard Connection is via the Line level RCA phono Inputs. 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.

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 POWER 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 sub-woofer is set to 'ON ‘or YES. The sub-woofer 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. Set the distance (or delay) setting that is correct for the sub-woofer position you have chosen.
Connecting the 2070Si
Multi-Channel AV System
Setting Up
Play some stereo music you are familiar with and experiment with the Phase invert setting and level control 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. Once you are happy with the sound you can then fine tune the performance by using the included CD.
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. Included with the 2070Si Subwoofer is a CD designed to assist in the setup of the AV amplifiers distance/time delay settings.
EN
Set-Up Disc: The disc contains six tracks, each one plays pink noise (20 Hz to 1000Hz) through a combination of one speaker and the subwoofer.
Track one: |
Subwoofer and Front Left speaker |
Track two: |
Subwoofer and Front Centre speaker |
Track three: |
Subwoofer and Front Right speaker |
Track four: |
Subwoofer and Rear Right speaker |
Track Five: |
Subwoofer and Rear Left speaker |
Track six: |
Subwoofer and all speakers |
Choose whichever front speaker is closest to the subwoofer and play the corresponding track. For instance if it is the front right speaker then play track three. Adjust the amplifier distance/time delay settings for the subwoofer by the smallest amount possible. This can be increased or decreased, it's not important which. For instance if the distance is set to 4m then change it to 4.1m or 3.9m. Listen to see if the pink noise becomes warmer and fuller or thinner in tone.
If you chose 4.1m and the sound became fuller in tone then change the setting again to 4.2m and so on until the sound starts to become thinner again. If however when you changed to 4.1m and the sound became thinner try reducing the setting to 3.9m. In this way it should be possible to find the optimum (warmest) setting.
