Troubleshooting the
Architect
Almost all problems can be eliminated by re-checking the
wiring and settings of the Architect amplifier. If a problem cannot
be solved using the guide below, please call the AudioControl
factory for further assistance.
1. No Sound:
• Verify the Power LED in on.
• Verify Protection LED is Green.
• Verify Channel Status LED is Green.
• Verify Source unit is operating.
• Check the Speaker Connector plug on the rear panel
• Check the AC Power Fuse on the rear panel.
2. Protection LED is Green, but neither Channel Status LED is on:
• Defeat the Signal-Sense circuit using switch on rear panel.
Both Channel Status LEDs should turn on. If they do not,
call the AudioControl factory.
• Verify Source unit is operating.
• Adjust the preamp volume higher.
• Adjust the Input Sensitivity control lower.
3. Channel Status LED is Amber:
• Check speaker leads for short.
• If the Architect is excessively hot (you cannot hold your
hand on the top), turn down the volume and allow it to
cool off. The Status LED should turn back to Green after a
short while. Verify that the ventilation holes on the rear and
sides have not become blocked.
• The speaker impedance may be too low.
4. Protection LED is Amber:
• Something seriously wrong has happened inside the
Architect. Call the AudioControl factory.
5. Speaker Buzzing or Cracking at high volume:
• Reduce the equalizer boost at 45Hz or 150Hz.
• Try a higher PFM filter frequency. The factory setting is
40Hz.
6. There is no audio input signal, but the Channel Status LED
is still Green:
• Check the Signal-Sense defeat switch on the rear panel. If
it is pressed in, the Channel Status LEDs will stay on as
long as the Remote Power Control is enabled.
• The Channel Status LEDs stays on for several minutes
after the audio signal has stopped to prevent prematurely
turning off during quiet passages or disk changes.
