Sound Reinforcement for Collina for Tsunami Victims

Fayid at Colina for Tsunami VictimsI was called to engineer the sound at Collina for Tsunami Victims held on the 7th of January 2007 at the National Stadium, Male’, Maldives. The event was organized by Haveeru Daily and was broadcast live on TV, radio and on web stream. A mixed line-up from Atoll Records performed two songs – one a theme song for the event and “Mithuraa”.

Two percussionists played a Band Bass Drum and a small snare along with Chinese Drums in the theme song. I had to use gated compressors to clean them up for the mix as there wasn’t a clear definition of tone in the Chinese Drums. As always, I spent a great deal of time cleaning up the tones from the source, for example, from the amps, before the mix.

I had to call in extra help because, the band was setup on the steps of the stadium and we couldn’t run our snake in front of the house. Also, Hambe was on the drums this time and not behind the stage. After a bit of brainstorming on who could understand what I say on the two-way radio, I decided on Fasy.

    After the sound check,you were setting the feedback suppressor. Can you explain me the use of it?and is it necessary in all the gigs?

  • Feedback suppressors eliminate the usually high pitched and undesirable squeals that occur when some frequencies output from the speakers are unintentionally looped back into the microphone or an input device.

    Feedback suppressors are especially useful when dealing with mission critical situations in less than ideal conditions.

    On this occasion, I used the Advanced Feedback Suppressor (AFS) of the dbx Drive Rack PA. The AFS on the Drive Rack PA offers customs settings for both fixed and live filters (that dynamically detects feedbacks as it occurs, in real-time).

    Advanced feedback suppressors are able to notch very tight Qs [Q=frequency/bandwidth] compared to an EQ, resulting in almost negligible or lossless change in the overall frequency envelope. In other words, you won’t notice a change in the shape of the sound while it is eliminating the feedback.

    Do you need it in all your gigs? The answer is No. Feedbacks should first be avoided by proper setting of the gain of the system, with well placed mics and careful consideration of speaker placements in the venue.

    An AFS is generally needed if all else fails or, if there is a high chance that feedbacks are likely to occur.
