Getting The Best From Your QM350i
Connections
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.
Two Neutrik™ Speakon model NL-4 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 disconnect.
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 8Ω 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.

QM 350i
User Manual
Speaker cables
Speaker cable needs to be as heavy gauge as conveniently possible for low-loss results.
Light gauge cable (below 1.5mm) will create extra resistance and waste amplifier power.
This particularly applies to long speaker runs. The amplifier’s damping factor statistic
(“punch” for the non technical) is greatly diminished, so keep your speaker cables short and as heavy gauge as practical.
Speaker Placement as a Single Box or in Arrays
The QM350i is intended for use as a single speaker system or as part of a multiple speaker setup with or without sub bass reinforcement. It can also be installed in small arrays of up to three boxes per array for very wide coverage applications. When a group of point source 90 degree speaker boxes are placed together, it is possible to have
“interference effect” between some of the boxes causing uneven frequency response.
This can be particularly noticeable in the mid-high frequency area. If you intend to set up the QM350i as part of a multiple box array, see the section ‘Flying the QM350i’.
When positioning the speaker system on a stage, make sure the HF horn at the top of the speaker box is above the heads of the audience. At full power the output of the
QM350i is very high and hearing damage can result from short to medium term exposure.
When used as a drum-fill monitor on a stage, the box can sit on the stage however consider that the HF horn will be at ear level for the average drummer setup.
For best results when the QM350i is used as a front of house speaker, consider angling the box forward slightly to direct the HF horn to cover the audience area. The HF horn should be aimed away from the ceiling and focused on the intended area of coverage. This will minimize HF reflections, lower the reverberant field in the room and give better intelligibility.
