Hardware Detail 2.1 Power Connection To power the amplifier board, use terminal blocks CONN1. This board need to be powered by two 65V 7.5A power supply. The positive of one supply is connected to +B and the negative connected to Gnd. TABLE 2-2 INPUT CONNECTION Connector Mark Channel Description RCA1A Channel 1 Input RCA connector RCA1B Channel 2 Input 2.3 Output Connections You can use terminal blocks SPKR1A、SPKR1B to output audio signal. FIGURE 2-3 OUTPUT CONNECTION © 2004-2012 Sure Electronics Inc. AA-AB32291Ver1.0Page 5. LEDs are used for indicating PWM mode.
When powered on, after one second delay, the two blue LEDs turn ON which indicates that PWM oscillation is present. This transition delay time is controlled by CSD pin of IRS2092, capacitor CP3.
