3. Using the Menu arrow, scroll down through the Diagnostics Menu and select AUDIO I/O TESTS.
4. In the AUDIO I/O TEST menu, highlight AUDIO INPUT 1 TEST. Press the Menu
the test. The RV-8 is now set to route audio from the left and right analog inputs labeled 1 to all Main
Zone outputs.
5. Power on the external amplifier. Slowly increase the volume on the external amplifier to a comfortable
listening level.
6. Sweep the oscillator from 20Hz to 20kHz. Verify that clean, undistorted audio can be heard
throughout the frequency sweep.
7. Power down the external amplifier.
8. Once complete, repeat steps 5 through 7 to test the remaining paired RCA outputs (Center/Sub, Side
L/R, and Rear L/R). Repeat steps 5 through 7 to test Analog Inputs 2 through 8. Change the INPUT
TEST selected in step 4 to the next appropriate input. Switch the Oscillator outputs to the RV-8 input
that corresponds to the input selected in the AUDIO I/O TEST menu.
Analog Inputs to Amplifier Outputs Test
This test will verify the audio path between the paired analog inputs labeled 1 to 8 and all analog amp
output channels.
Test:
1. Connect the low distortion oscillator output to the left and right analog audio inputs labeled 1 on the
rear panel of the RV-8.
2. With the RV-8 powered off, connect the RV-8 amplifier front left and front right outputs to the pair of
speakers.
3. Power on the RV-8.
4. Using the Menu /
5. In the AUDIO I/O TESTS menu, highlight the AMP TEST. Press the remote control Menu
engage the test. The RV-8 is now set to route audio from the left and right analog inputs labeled 1 to
all amplifier outputs.
6. Using the volume knob on the front panel of the RV-8, slowly increase the volume to a comfortable
listening level.
7. Sweep the oscillator from 20Hz to 20kHz. Verify that clean, undistorted audio can be heard
throughout the frequency sweep.
8. Lower the volume of the RV-8.
9. Power off the RV-8 and carefully disconnect the front left and front right speaker wires from the RV-8
amplifier outputs and connect them to the side left and side right amplifier outputs.
10. Power on the RV-8 and repeat steps 5 to 7.
11. Repeat steps 5 to 9 to test the RV-8 amplifier outputs for the rear left, rear right, and center channel
outputs.
