The JBL 6006 is a highly reliable, conservatively rated amplifier, designed for professional sound engineering applications where a high degree of performance is required.
The circuitry has been carefully designed to reduce the possibil- ity of failure within the specified environmental and electrical conditions. A protective circuit is utilized in this amplifier which makes it virtually impossible to damage it under any conditions of overload, including shorted or grossly mismatched load, inductive load at low frequencies, capacitive load at high frequencies, excessive input signal, white noise or i:istallation errors.
The JBL 6006 can be overdriven by at least ten times normal input voltage, from 40-15 kHz, and eventually produces square waves increasing in RMS value up to about 110 watts at which point the output actually begins to decrease.
The DC fuse is intended as a protective device for the power supply in the event of output stage malfunction. It is not intended to protect the output transistors which are guarded the special circuitry provided. As an indication of high- frequency stability, the JBL 6006 draws only 30% more power from the AC line at 15 kHz, 60W, than at 1 kHz for at least one hour without malfunction or entering the “protect” mode.
