LEVEL CONTROL Min. fan speed, TPC normal Fan speed Fig.2.1 Front Panel Level Control Amplifier: DP Series The following diagram illustrates the actions taken by the Thermal Management System: Fig.2.2 TPC Load Impedance: Safe with all types of loads. Rated at 4 to 8 ohms in Stereo, 4 to 8ohms in Bridge-Mono and 4 to 8 ohms in Parallel-Mono mode. - Page 11 Channel 1 inputs are active; Both channel volume controls are available. Protection DP Series amplifiers are protected against shorted circuits or mismatched loads, overloaded power supplies, excessive temperature, chain destruction phenomena, input overload and high frequency blowups. They also protect loudspeakers from input and output DC and provide protection from turn-on/turn-off transients.
