TP33-34 & TP35-36: AC VOLTAGES SHOWN ARE FOR MEASUREMENTS TAKEN BETWEEN TP AND CHASSIS GROUND. THE VALUES WILL BE TWICE AS LARGE IF MEASURED WITH THE VOLMETER BETWEEN DIRECTLY ACROSS THE AMPLIFIER OUTPUT (BETWEEN TP33-34, OR TP35-36).
NOTE: 50ASX2 MODULE USES SWITCHING TECHNOLOGY RESULTING IN HIGH FREQUENCY NOISE ( >100kHz) AT THE OUTPUT. RECOMMEND USING A LOW­PASS FILTER (SUCH AS THE AP AUX-0025 SWITCHING AMPLIFIER MEASUREMENT FILTER) FOR OPTIMUM VIEWING AND MEASURMENT OF OUTPUT SIGNALS.
