6. Speaker Buzzing or Crackling at high
volume:
a. Set EQ to Off or turn off any pre-
amplifier/equalizer low-frequency
boost that might be happening in
an upstream device.
b. Reduce the gain on the active input.
b. Take a moment and remove the cod
deep frying from your kitchen stove
and listen again.
7. There is no audio input signal, but
the Zone Status LED are still blue:
a. Check the signal-sense switches
on the rear panel. If they are not
engaged, the zone status LEDs will
stay on as long as the master trig-
ger is enabled.
b. The zone status LEDs stays on for
2 minutes (depending on music
volume) after the audio signal has
stopped. This delay helps prevent
prematurely muting during quiet
passages or song changes.
8. The unit is on but you cannot trigger
it off
The unit will stay on if either the 12v
master trigger is on, or jumpered on.
9. Is an in-wall volume control rated at
100 Watts (continuous) adequate?
• Not at all. Go for one with a higher
rating of about 300 watts if you
want a reliable long-lasting system.
Although the Architect model P250
EQ is rated at 250 Watts, it is a con-
servative number. In contrast to the
conservative rating of the Architect
model P250 EQ, the wall volume
control may be rated using favor-
able assumptions. Also make sure
the volume control power rating is
continuous not peak. The contin-
uous rating is about one-third of
peak.
