    ANALOGUE SIGNAL PROCESSING 7.1 Signal path The SB8A/SB10A input board performs a number of important functions that are useful to understand. Unlike most active/powered speakers, the SB8A/SB10A is 100% analogue, with no DSP or digital conversion. This block diagram shows the internal signal path of the SB8A/SB10A.

  • Page 22: Setup

    S B8A/ S B10A U S e r U i d e SETUP 8.1 Loudspeaker placement To enjoy the full dimension available from stereo choose a listening position midway between the satellites and in front of them so that the angle from the satellites to the listening position is around 90° or greater as illustrated below.

  • Page 23: Installed Vertical Aiming

    SETUP 8.2 Installed vertical aiming When considering your satellites position take into consideration the required coverage area and the average listening position. Avoid aiming your satellites over the audience’s heads as this will increase negative room effects causing poor impact and intelligibility, your audience will enjoy far better sound quality with the satellites aiming towards them.

  • Page 24: Installed Horizontal Aiming

    S B8A/ S B10A U S e r U i d e 8.3 Installed horizontal aiming Avoid aiming your satellites straight into a room, this can increase side wall effects causing coverage gaps between the loudspeakers and poor stereo imaging.

  • Page 25: Timing Optimisation

    TIMING OPTIMISATION 9.1 Position tuning With any multi-way loudspeaker system for maximum accuracy and listening pleasure it’s very important to have the different frequency bands synchronised in time. At the crossover frequency it is even more critical where more than one speaker is reproducing the same frequency range. Bad timing can give a hole in the frequency response due to energy cancellation (out of phase) or good timing can give mutual reinforcement and a seamless join between the mid bass and low mid frequencies (in phase) as illustrated in the following diagrams.

  • Page 26: Using The Polarity Switch

    S B8A/ S B10A U S e r U i d e 9.2 Using the polarity switch to assist phase alignment Whilst playing music with a defined kick drum and percussive bassline, switch the bass polarity to negative. If the mid bass gets weaker in level and impact, switch the polarity back to positive. If the mid bass gets stronger with the polarity set to negative, leave it that way.

  • Page 27: Room Acoustics

    9.3 Room acoustics A typical home environment will have hard reflective walls and ceiling which will add a degree of confusion to all sources of audio in the room. This is often mitigated by carpet, curtains and soft furnishings in general. Sound treatment is usually based on absorbent materials such as curtains or dedicated sound panels.

  • Page 36: 1 Appendix

    Typically this functions by leaving the quieter tracks alone, and turning down the loud tracks. Whilst this is a good idea in principle, when playing music from a phone into the SB8A/SB10A, you may find the maximum output is limited as a result of the volume normalisation. This is because the input sensitivity of the SB8A/SB10A has been chosen for maximum compatibility with the widest range of sources.

  • Page 37: Room Modes

    1 1.2 Room modes Even if you’re not familiar with the terminology, you may have noticed room modes before, when the bass is very loud in one part of the room, and almost non-existent in another part of the room. This because the waves reflect from the walls and produce standing waves or resonances, or commonly, modes.

  • Page 38: Sound Waves

    S B8A/ S B10A U S e r U i d e 1 1.3 Sound Waves Sound waves are modulation of air pressure. The metric unit of pressure is a Pascal, a force of one newton over an area of one meter squared. The dynamic range of audible sound is extremely large, from 0.00002 Pascals (the threshold of hearing) to 20 Pascals (threshold of pain).
