connectors are mounted in a removable panel
on the rear surface of the box.
The connector input is wired pin 1+ and pin
1-.
Pin 2 is not connected.
Take care when inserting the Speakon
connector twisting the connector until it
locks into place. Reverse the procedure to

Getting The Best From Your QM350i
Suitable Amplification
The QM350i is an 8 ohm enclosure and can
be connected in multiple parallel connections
to an amplifier channel that can operate at
speaker impedances of 4 ohms.
The QM350i is a mid power level high
efficiency system, so ultra high power is not
necessary to obtain high sound pressure
levels. The recommended power range per
amplifier channel is 350 - 500 watts RMS into
an 8
Ω
load or up to 1,000W RMS into a 4 ohm
load. An ideal partner to the QM350i are any
of the Quest QA range of amplifiers. Setting
the QA amplifier’s high pass filter at 35Hz is
recommended for full range applications. If
you are intending to add sub bass speakers,
the high pass filter can be set to 80Hz.
