Operation
Connecting between the speakers
Firstly, connect the supplied speaker cable between the two speakers. The
wires are coloured differently to identify + and – polarity. Ensure you always
use the gold wire for + and silver wire for – at both ends.
Speaker positioning and assembly
Simply place the speakers either side of the main listening position on an
appropriate flat surface, ideally about 2.0 – 4.0m (2-4 yards) apart.
Alternatively you can use Q M-20 with the Q 3000FSi floor stand or Q 3000WB
wall bracket (available separately), follow the instructions supplied with
these.
- The amplified speaker can be placed in either the right or left position, simply set the left/right switch correctly. The switch sets left or right channel for the amplified speaker.
Adjusting the EQ switch
- You can adjust the bass response of the speakers to suit your desired bass level which is affected by the speaker position in relation to a wall, shelf, or corner. Try listening to your M-20 speakers in each of the three positions, selecting the one that you are most happy with.
- This position will give the most bass output and is suited if the speakers are placed away from walls or corners.
- This position will give a mid-point in bass output and is suited if the speakers are placed close to a wall or on a shelf.
- This position will give the least level of bass output and is suited if the speakers are placed in corners of the room.
Optional subwoofer
A subwoofer may be connected to the SUB outlet as an option. The subwoofer should include level and crossover controls. With the subwoofer connected, play some music with good bass content and adjust the subwoofer controls for the sound you prefer.
Port damping
The Q M-20 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.
- 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.
Powering on
- Connect the power cable to the amplified speaker and plug into a mains outlet.
- Once powered up the standby LED will be on red.
- To switch the system on, press on the remote or the control panel.
- To set the system to standby, press on the remote or long press on the control panel.
Auto standby
The Q M-20 system includes an energy saving auto standby feature. If no music has played for twenty minutes the system will automatically set to Standby.
