Now that all equipment is connected,
controls as follows: Boom-box
control to 5, and CHANNEL 2 & 3 LEVEL control to 0;
receiver “AF LEVEL” to maximum (full clockwise);
To set sound levels in this step, you will need three synchronized swimmers in the following
locations: under the water, on top of the water, and in the bleachers. Connect the Peavey
power cord and tape deck power cord into an audio grade surge protected power strip, then to the
/cassette (or boom-box), and advance the music to a known section
of music that is very loud. Slowly turn up the Peavey
the submerged swimmer indicates (with thumb up or down) that the
sound level is correct and
undistorted. Now turn the
control up or down until the
the bleacher person indicates that the air sound level is correct
(compromise if necessary). The
should not be touched again during the practice or competition
competition, you will need to keep your fingers on the Peavey
knob at all times to keep the sound level consistent from tape to tape. If you have not
trained your ears to recognize a consistent level, you can use a Radio Shack Sound Level Meter
(33-2050 @ $39.99) from your table to observe and maintain a consistent sound level reading in
When playing tapes of varying level and quality during the meet, listen carefully to what you hear
from the air speaker, and use the Peavey
equalizer controls (sparingly) to maintain a consistent sound level and tonal quality.
Always return equalizer controls to 0 position when inserting the next team’s tape. Avoid using
the mid equalizer control or contour controls - leave at 0 position. If you hear distortion in the air
speaker, then the swimmers will also hear this distortion in the underwater speaker -- reduce the
control immediately until the distortion is no longer heard.
Always use the microphone(s)
the air speaker to minimize squeal. Hold microphone
against lips, speak in a strong voice, and turn the CHANNEL
CHANNEL 3 LEVEL knob (wireless mic) up on the Peavey
amplifier until the desired
sound level is reached. If no sound, then fully reduce
the CHANNEL 2 and/or 3 LEVEL
amp, and check the microphone connections and power switch. Once
connections are corrected and/or power is turned on, then turn up the CHANNEL 2 and/or 3
LEVEL knob until microphone sound level adequate.
MICROPHONE SQUEAL -- this is harmful to the swimmers, audience, and the loudspeakers. If
squeal starts, immediately turn microphone off using switch on microphone, then lower
microphone volume control on amplifier.
After using equipment, tear down in reverse order. Inspect all cables for damage. Towel dry the
speaker, and carefully coil the speaker cable inside the cage recess (just as you would coil a
garden hose). Store all equipment in a dry, air conditioned equipment room far from the damaging
