14.1.14. CBT36 Sensitivity and Maximum SPL:
The following graph shows the simulated sensitivity and maximum SPL of the CBT36. Separate curves
are shown above and below the 1 kHz crossover due to different power-handling capabilities of the LF
and HF sections. These curves assume no power limiting by the shading resistors internal to the CBT36
with the system set up in a “pro sound” configuration. See previous comments in section “CBT36
Specifications in Brief:” under specification “Maximum Input Voltage and Power:”
Fig. 32. Graph of the approximate CBT36 2.83 Vrms/1m sensitivity and maximum continuous
and short-term SPL. The levels are frequency dependent and reach a maximum between 80
and 300 Hz. The curves roll off at higher frequencies at 3 dB/octave or 10 dB/decade. Separate
curves are shown above and below the 1 kHz crossover for LF (continuous line) and HF
(dashed line). For max SPL, these curves assume a “pro-sound” configuration of the CBT36
with high-power shading resistors.
