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 disconnect.
Getting The Best From Your QS350i
Suitable Amplification
The QS350i 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 QS350i 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 QS350i 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.

Reducing low frequency output will make more amplifier
power available for clean vocal reproduction for full range
sound, set the high pass filter to 35Hz
