User manual for the Crest Audio Pro-LITE 7.5 Professional Power Amplifier 3602200
The user manual for the Crest Audio Pro-LITE 7.5 Professional Power Amplifier 3602200 provides
necessary instructions for the proper use of the product Pro Audio - Live Sound - Power Amplifiers.
The 2RU, 7500W Pro-LITE 7.5 Professional Power Amplifier from Crest Audio is designed with a resonant switch-mode power supply and high-speed class D topology. The automatic clip limiting (ACL) circuit is designed to ensure trouble-free operation into loads as low as 2 Ω.
The front panel of the Pro-LITE 7.5 features two attenuators for lowering the output signal from 0 to -80 dB for each channel, while the 5 LED indicators offer feedback for both channels of the amplifiers operations including active, DC, temperature, signal, and ACL.
The rear panel provides two combo XLR/1/4" inputs and two 1/4" thru outputs for connecting to additional amplifiers. Speaker output connections include one 2-pin and one 4-pin twist-lock connector, which accommodates two 2-conductor or one 4-conductor speaker cables. The crossover select switch offers three settings: Full Range, Sub, and High Cut. Sub removes frequencies above 100 Hz, while high-cut removes frequencies below 100 Hz. The amplifier provides three temperature dependent variable-speed fans, while protection circuits guard against thermal overload, direct current, incorrect loads, and under & over voltages. The Pro-LITE 7.5 ships with an IEC power cable.
