JBL 3120A

Commentary

A dividing network with a crossover frequency of 1.2 kHz.

After careful testing, we employ high-voltage, non-inductive, non-polar capacitors developed specifically for networks, finely tuned low-loss inductors, resistors that withstand harsh use, and switches for high currents.
In addition, in order to obtain an accurate crossover frequency, a unique impedance correction circuit is used for the low frequency.

The 3120A is designed for two way use. In addition to the conventional trans-3-position attenuation, it is equipped with a high-frequency boost circuit to provide optimum frequency response when a biradial horn is used for SR.
