Surround Monitoring - Tannoy Reveal 501a Owner's Manual

10 SURROUND MONITORING

In order to ensure a uniform acoustical environment, the room should be symmetrical about the centre loudspeaker
axis; room treatments should be applied symmetrically throughout the room. mixed "live end/Dead end" environments
should be avoided. If the lateral speakers are positioned close to walls then the constitution of the wall surfaces should
be identical.
when using either reveal 501a or 601a as the main effects speaker for the front soundstage, placement is a critical
factor for good performance.
In all cases the centre channel speaker should be placed as close to the viewing screen as possible. The viewing
position when seated determines the ideal mounting height, but in all cases this should be as close as possible to ear
height, if this is not possible the monitor should be tilted towards ear height in the mix position. The centre speaker
should be positioned along the centre axis of the picture and the left/ right monitors just outside the picture, ideally
the three front effects speakers would be placed with the front baffles in line with the screen surface. If an acoustically
transparent screen is used, the left/right monitors should be placed just inside the edges of the picture. The surround
speakers should be positioned at the same distance to the mix position as the main front speakers. as the subwoofer/
LFE channel only produces low frequencies it is difficult to localise its position by ear. as a result it could effectively be
situated anywhere in the room, though optimum performance will be gained by placing the subwoofer in the same plane
as the main front speakers. The lFe channel is set at a level 10dB higher than the other channels when mixing therefore
it is important to apply the same in any playback situation
