Input Clip Indicator Setup
Step 1. Be sure to disconnect all speakers from the
amplifier.
Failure to comply may cause damage to
connected components and/or amplifier.
Step 2. Turn on the source unit with volume set to zero.
Step 3. Adjust the Bass & Treble levels on the source unit to flat.
Step 4. Insert test tone or music CD to play for setup.
Note: Use the 40Hz @ 0dB tone (Track 5) for mono amplifier applications
or the 1kHz @ 0dB tone (Track 7) for multi-channel amplifier
applications. Be sure your x-over is switched to the appropriate filter
setting (LP/HP).
Step 5. Increase the source unit volume until the Input Clip Indicator
illuminates red.
Step 6. Decrease the source unit volume slightly until the light turns
completely o. This establishes your maximum source unit
volume for adjusting the Output Clip Indicator.
Note: Some source units will not clip.
Output Clip Indicator Setup
Step 7. Adjust the Gain knob until the Output Clip Indicator
illuminates to the appropriate color. Repeat for all channel
levels of input.
Step 8. Turn the source unit volume down.
Step 9. Reconnect all speakers. Be sure to maintain
proper speaker polarity.
