JBL rmc User Manual

Chart Paper: As you play test tones on the CD through the system, you will plot the read-
ings on the chart paper. A calibration procedure will ensure that the signals you read will
fit within the window of the meter. Any signals that appear below -16 dB will simply be
entered along the bottom edge of the chart. We recommend you make photo copies of the
chart paper for your use, and keep the original master for future duplication. When dupli-
cating, do not enlarge or reduce the size of the chart.

A view of the chart is shown in Figure 3, with the level scale at the left and the frequency
scale at the bottom. Below the chart are areas for you to enter your collected data:
Frequency (Hz), Level (dB), and Width (%).

The 9-Volt Battery: should be installed in the Sound Level Meter prior to use.

The RMC Remote Bypass Control: when connected to an LSR6328P or LSR6312SP, allows
you to bypass the RMC system from the listening position for before-and-after compar-
isons. You may use mono (tip-sleeve) 1/4” cables such as guitar cables to make the con-
nections as shown below.
