CASCADE MODEL FIFTEEN
Power is switched on or off by pressing the button directly below
the bar-graph window. When the unit is on, one or more LEDs will
always be illuminated. The function of the LEDs is described in
the following section.
• Power-On/Under-Range (Low Signal): This is indicated by the
illumination of any LED on the bar graph. If the sound level in the
room is below the measurement range of the instrument, a green
LED near the bottom of the bar graph will be illuminated.
• Measurement In-Range (Normal Measurements): When the
sound level is within the range of the RSLM, the green LED
will be off and one of the red LEDs in the bar graph will be
illuminated, indicating the relative sound level, in decibels (dB).
• Over-Range: If the sound level exceeds the range of the meter,
0dB through –5dB will all light simultaneously.
• Low Battery: When the battery voltage is too low for accurate
measurements, an LED at the bottom of the bar graph will be
illuminated. Replace the battery.
Do not attempt measurements when this light is on.
RSLM Placement
Determine where in the room you are most likely to sit when
listening to music or watching a movie.This is where you will
want to hold the RSLM during measurements. The RSLM should
be oriented so it can be easily read and held at your seated
ear level during tests.
You must use this same position for all tests.
The RSLM can be mounted on a standard camera tripod.
This will ensure the best results.
Tracks 53–62 of the R.A.B.O.S.Test CD are test tones that can be
used for general diagnostics of your system. They are not used
for R.A.B.O.S. settings.
THE R.A.B.O.S. SOUND-LEVEL METER (RSLM)
The RSLM is a battery-operated, handheld, acoustic measurement
device specifically designed for Infinity R.A.B.O.S. On the face of
the instrument is a light-emitting diode (LED) bar graph that
indicates relative sound level. There are also indicators for
power-on, out-of-range signals and a low battery.
