3. 502B Equalizer Curve
Use the following test set-up parameters when measuring the 502B card's response outputs:
A. Apply a signal of 80 Hz at 1 Vrms and adjust the amplifier's output to 6 Vrms.
B. Reference a dB meter to the output.
C. Measure the response according to the following chart.
4. 802 Equalizer Curve
Use the following test set-up parameters when measuring Full Range or High Frequency response
outputs:
A. Apply a signal of 700 Hz at 1 Vrms and adjust the amplifier's output to 6 Vrms.
B. Reference a dB meter to the output.
C. Measure the response according to the charts in Sections 4.1 and 4.2.
2.2 502A High Frequency Response
IMPORTANT: Set the Input Module's S2 switch to the HF Only (High Frequency) position before
beginning this test.
4.1 802 Full Range Frequency Response
IMPORTANT: Set the Input Module's S2 switch to the Full Bandwidth (Full Range) position before
beginning this test.
