Description

The TOA A-506A is designed for PA system applications such as paging, announcements, intercommunications, background music and broadcasting in industrial plants, offices schools, churches, department stores, shopping centers, night clubs, dining rooms, convention halls, auditoriums and recreation areas. The A-506A’s main feature is its ability to withstand overload or short-circuits of output. Because of the TOA-engineered circuitry design, the TOA 500 series amplifier requires no complicated protective circuit to withstand accidents and mismatched output connections that may occur during the installation or use of a PA system. This results in very high reliability. The A-506A comes with 4 microphone inputs, 3 auxiliary inputs and a mag. Phone input. Input 1 (Mic 1) and Input 2 (Mic 2) out of the 4 mic inputs are balanced inputs, while Input 3 (Mic 3) and Input 4 (Mic4) are of unbalanced type. Input 3 and Input 4 can be changed to balanced type with the LI-51 microphone input module (not included). Two condenser microphone can be used with phantom power supplied from Input 1 and 2. And they have a remote volume control circuit on Input 2 as the volume can be adjusted at the microphone even when it is distant from the amplifier. The amplifier is equipped the muting function. It can be used in conjunction with a speaker rated at 4 ohms or with 25volt, 70volt constant-voltage speaker systems. Three auxiliary inputs and a mag. phono input are provided with RCA pin jack. Preamp-Out and Power-Amp-In receptacles are provided for easy connection of a signal processor to the amplifier. Emergency operation can be made by DC power source (24V DC) even in case of AC power failure.
