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.

Figure 2. R.A.B.O.S. Sound-Level Meter

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.

Figure 3. RSLM bar-graph indications

Power-On/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.

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 –5 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.
