Frequently asked questions
Does it need a separate amplifier or top speaker?
The subwoofer has its own amplifier, but reproduces bass rather than the full audio range. Use suitable powered top speakers, or top speakers with their own amplification. Arrange the audio source, speakers and required cabling separately.
Which low-pass preset should I use?
Choose 80, 100 or 120 Hz to match the top speakers and system alignment. These are upper low-pass limits, not the point where bass starts. The manual recommends 100 Hz with STINGER G3 full-range speakers. THRU outputs are not high-pass filtered.
Can one unit produce a cardioid bass pattern?
No. The manual specifies three STINGER G3 subwoofers of the same model: two facing forward at 100 Hz and the middle unit facing backward in CARDIOID mode. All three need the same signal and identical MAIN LEVEL settings. Follow the manual layout; this single-unit rental does not include that array.
Are wheels, a cover, cables or a pole included?
No accessory package is specified here. Confirm any required transport protection, dolly, matching mains lead, audio cables and M20 pole when arranging the rental. Check vehicle space against the cabinet dimensions and use suitable handling assistance.
