BTB Project used Crown CTs 600 Power Amplifier for their BGM System
The power amplifier shall be a solid-state two-channel model employing Multi-Mode® (AB+B) output circuitry.The power amplifier shall be a solid-state two-channel model employing
Multi-Mode® (AB+B) output circuitry.
The amplifier shall contain protection circuitry which limits the drive level
placed on the output devices before their SOA (Safe Operating Area) is
exceeded.This protection circuitry shall calculate the instantaneous voltage
across and current through the output devices while factoring in their
simulated junction temperatures to predict how close they are to their
operating limits. This protection shall be called “JTS.”
The amplifier shall contain protection from shorted, open and mismatched
loads, general overheating, DC, high-frequency overloads, under/over voltage
and internal faults.
If an amplifier channel starts to overheat, the Thermal Level Control (TLC)
circuit shall engage that channel’s input compressor in an amount proportional
to the amount of overheating, in order to generate less heat. If the channel becomes too hot for safe operation, the channel shall shut off and the Thermal Indicator for that channel shall illuminate brightly to alert the user that a state of thermal stress or overload has caused the channel to shut down.
The front-panel control shall be a power switch. Rear-mounted controls shall include Channel Level Controls, High Pass Filter Switches (one per channel), and a Mode Switch. The High Pass Filter Switch shall select between fl at and two positions of roll off. The two position Mode Switch selects between Dual or Bridge-Mono operation.
