Positioning the Sound. Use the PAN and BLEND

controls to position the sound within the LCR image.

It is possible to dynamically move the sound using

the two controls together but this is not a common

requirement in real world systems. For example,

dynamically panning an actor as he moves across a

theatre stage may be uncomfortable for the front

row listeners who hears the voice move from say

the left speaker upwards to the hung centre

speaker, and then back down to the right rather

than evenly across the stage. Static positioning is

more common in the theatre situation where the ear

adjusts to and accepts the source of the sound.

PAN L. To position the sound at the left speaker

only set PAN fully left and BLEND to LR.

PAN L to C. To position the sound between the

left and centre speaker set PAN fully left and adjust

BLEND clockwise from LR to C.

PAN C to R. To position the sound between the

centre and right speaker set PAN fully right and

adjust BLEND anticlockwise from C back to LR.

PAN R. To position the sound at the right speaker

only set PAN fully right and BLEND to LR.

Focussing the Sound. Typically, a large music

venue or festival may use an LCR system with

vocals and key sounds such as kick and bass fed to

the main centre cluster and backing instruments fed

to the LR stacks. This helps the clarity and

intelligibility of these sounds.

Use BLEND to position each sound in the LR or C

speakers. You can dynamically bring a sound

forward by panning it from LR to C. For example,

use this to improve the focus of a backing

instrument such as guitar for the duration of a lead

solo. Pan it back from C to LR again after the solo.

Blending the Sound between Speakers. In non-

ideal situations where the three speakers do not

cover all the audience evenly, a small portion of

centre cluster lead sounds such as vocals can be

blended into the LR stacks so improving coverage.

Similarly, LR sounds can be blended into the centre

cluster.

Using the two controls you can adjust the balance

smoothly listening to the results and being able to

make small changes without the big jumps in

volume associated with switched routing.

While you could use the matrix to balance groups of

sounds between the speakers, LCRplus lets you

balance the image independently for each sound.
