Troubleshooting - Peavey Aquarius AQ Series Operating Manual

Bluetooth® Range Information
This is a Class 2 Bluetooth® device, and as such is designed to have a typical maximum range of approximately
10m (33 feet).
However, any intervening materials, such as walls, shelves, screens, people, or most anything made of a substan-
tial amount of metal, can reduce and affect that range.
Disconnecting AC Power to the AQ™15
We recommend that the Power switch (3) be used to turn the unit off first, and then the AC power cord can be
removed, this minimizes stress to the power amplifiers and the transducers from turn-off transients. The pow-
er switch has an arc suppression capacitor to help during turn-off, and tends to make a clean disconnect from
the AC power, while the power cord IEC connector can make intermittent contact before finally becoming fully
disconnected, e.g., as when wiggling the cord.

Troubleshooting

No Output at All
First, make sure the unit has AC power and is turned ON. Make sure the LED on the power amp module is
illuminated.
If not, make certain the ON/OFF switch (3) is in the ON position and check the IEC power cord connection (2)
by ensuring it is fully engaged and seated. Make certain the AC line cord is plugged into a working AC outlet.
Once assured your unit is getting AC power, check that the AQ™15 is getting a signal. Temporarily disconnect the
cable running to its inputs and connect it to some other device capable of reproducing the signal (i.e., a power
amp and speaker). If this produces a signal, make sure that all Gain controls being used have been turned up to a
satisfactory level (one-third to halfway).
If the AQ™15 has been subjected to direct sunlight or excessive heat, the built-in thermal protection may have
been triggered. If so, turn off the AQ™15 and let it cool for a sufficient amount of time.
If there is still no output, contact your authorized Peavey dealer or the Peavey International Service Center.
Hum or Buzz
If the AQ™15 is producing a hum or buzz, this can be AC outlet related. Try plugging the AQ™15 into a different
AC outlet. Sometimes, if a different
circuit (breaker) is used for the mixer and for the AQ™15, it can cause hum problems. Unless it is not practical, it
is best to use the same wall outlet (breaker) to supply power to both the mixer and the powered speaker.
Ensure that shielded cables have been used to route the signal to the AQ™15's input. If speaker cables with 1/4"
plugs are used as input cables instead of shielded cables, they will be prone to hum or buzz.
Hum may be ground loop related. It may be helpful to lift the shield ground (Pin #1) on a balanced cable at the
AQ™15 end. Check any input changes carefully by first turning down the level control, before plugging and un-
plugging cables, or lifting the shield ground at the speaker end.
