Last saturday we had an Indian classical music concert at Neurosciences auditorium. The group consisted of 4 instruments. A violin (Lalgudi G. J. R. Krishnan), a sitar (Gaurav Majumdar), a mridangam (Shreeram Brahmanandam) and a tabla (Kuntal Roy). We employed 3 L1s. See picture for the layout. Three T1 engines were employed. Both the violin and sitar were input to the middle speaker. That had one Bass module. The mridangam went to the the speaker on the left with 2 B1 modules. The table similarly went in to the right speaker with 2 B1 modules. This is a typical indian music concert where artists sat on the stage to perform. The speakers were roughly 8 ft behind the artists.
The artists did extensive sound test. The volumes were cranked up to a point where some feedback was detected. Then the volumes were set to th comfort of the artists. The auditorium seated about 300 (see attached). We had two additional (non-Bose) speakers facing the audience from the 10th row. These were set up just in case, the resulting volume levels were found to be low for the rear rows. Tests shoed the volume level to be very uniform at least for about 20 rows. The preamp output from T1s were connected to mackie 1640VLZ3. Outputs from mixer went into a Canon HD camcorder, Sony PCM-D1 pcm recorder and via an amplifier to the audience-facing speakers.
One young person (Vasista Avvaru) sat with the artists to assist in T1 adjustments during the concert. Very minimal adjustments were needed during the concert. The sound was superior.
The clarity of the sound was incredible. Bose L1s clearly made a very big improvement to the audio.
