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.
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.
Amplifier selection
The XY-1 and XY-2E are designed to be used with professional power amplifiers providing the following power outputs:
XY-1
:
2800 W/channel into 4
W
XY-2E : Passive mode - 540 W/channel into 8 Ω
Bi-amp mode - MF 400 W/channel into 8 Ω
HF 140 W/channel into 8 Ω
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 program 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-1 and XY-2E are supplied as standard with Neutrik SpeakON™ NL4 connectors, wired pin 1+/1-. It is recommended that the resistance of your cable be less than
one tenth of the nominal system impedance. Given below are the recommended maximum cable lengths for different cross-sections and impedances.
Pin 2+/2- on the Neutrik SpeakON™ connectors are wired together to allow link-through with 4-core cables.

Speaker protection and Processor setting
WARNING
The XY-1 and XY-2E require properly adjusted signal inputs optimized. Otherwise speaker units may deteriorate even if the power is below the power handling capacity.
It is recommended to appropriately set the values of signal processing such as crossover frequency, peak limiter, delay, equalizer.
Please see the document provided in these products support site for the recommended values to appropriately use this product.
