JBL continually strives to update and improve existing products, as well as create new ones. The
specifications and details in this and related JBL publications are therefore subject to change without notice.
*
The Peak Dynamic Power is measured by recording the highest center-to-peak voltage measured across the output of a resistive load equal to
minimum impedance of the transducer, using a 50Hz sine wave burst, 3 cycles on, 17 cycles off.

Other Parameters/Notes:
1. Limiter circuit response must be clean sounding with no apparent pops, noises, or pumping.
1. Limiter circuit response must be clean sounding with no apparent pops, noises, or pumping.
2. Plate dimensions not to exceed 11.81"H x 7.87"W and the plate must be airtight with no possibility of air leaks (plastic cover required).
3. Volume control should be at the input buffer stage in order to lessen the possibility of clipping the input section with highly dynamic audio material.
4. ALL SPECS SHOULD BE MEASURED AT NOMINAL LINE VOLTAGE.
