System set-up

WARNING

! Loudspeaker systems are potentially dangerous objects if used incorrectly. Please ensure that you read this section fully, and contact your local dealer should you be in

any doubt over correct operation procedures.

! Professional loudspeaker systems are capable of producing damage-inducing sound pressure levels, and hence care should be taken when setting your system up,

particularly when it comes to loudspeaker placement within a venue. Damage to the ear can result from levels above 90 dB under prolonged exposure.

Pole-mounted full-range loudspeakers from the XY-215S

The XY-215S can support other loudspeakers using an M20 threaded pole adapter. When mounting in this way, please consider the following:

! Ensure the M20 pole is screwed in tightly, your stand height is locked off and the system is stable.

! Do not stack a second loudspeaker on top of the stand-mounted one.

! Ensure cables are run so as to leave enough slack to enable neat wiring, and thus reduce the risk of the speaker being pulled over. Loose cables should be covered or

taped down wherever possible to reduce trip hazards.

Ground stacking

! Ensure that the floor or stage surface can withstand the weight of the system.

! Wherever possible, avoid high stacks and use ratchet straps to secure loudspeakers together. Please also remember that vibrations from subwoofer systems can shake

other loudspeakers out of place, which may present a toppling hazard. The use of ratchet straps and non-slip material is recommended to prevent this.

Cabling and amplifier selection

The XY-215S is designed to be used with professional power amplifiers providing the following power outputs:

! 1600 W/channel into 4 W

NOTE

A small power amplifier working too hard is more likely to damage a loudspeaker than a large power amplifier working within its operating range.

It is good practice to use an amplifier equal to the programme power rating of the loudspeaker — so as to retain sufficient headroom and good dynamic range. Care should be

taken during operation to avoid amplifier clipping — as this can cause serious damage to your loudspeakers. If in doubt, please contact your dealer who will be happy to assist

you in correct amplifier choice and setup.

Cabling

The XY-215S is supplied as standard with Neutrik SpeakON

the nominal system impedance. Given below are the recommended maximum cable lengths for different cross-sections and impedances.

Protective DSP settings

The XY-215S requires at the minimum an active low pass filter to function correctly. The settings below are given as a starting point — as the user you are given maximum

flexibility to adjust for your taste. To protect the drive unit, it is also advisable to apply a high pass filter to the system to protect the XY-215S drive unit from over-excursion from

frequencies it cannot reproduce.

The higher you raise the cut-off frequency on a high pass filter for an XY-215S, the more headroom and overall sound pressure level output there is available. For most medium-

to-high level applications, we would recommend a minimum of a 40 Hz high pass filter with a 24 dB/octave slope to sufficiently protect the loudspeaker. For higher SPL appli-

cations, we would recommend raising this cut-off even higher. We would stress that the higher the cut-off frequency, the safer the loudspeaker will be.
