For your own safety you should read this section

in full rst!

Risk of electrical shock!

• Connect the device only to a properly wired

and earthed electrical wall socket providing a

mains voltage of 230 V~/ 50 Hz.

• NEVER operate the device if the power plug or

power the cord is damaged.

• NEVER submerse the device in water. Wipe it

only with a slightly damp cloth.

• NEVER expose the device to rain or moisture and

never use it in a damp or wet environment.

• Ensure that the power cord does not become

wet during operation.

• You must NEVER open the housing of the device

or try to repair it. There are no user serviceable

parts inside. Warranty will become void if you

open the housing.

• Do not place objects containing uids, e.g.

ower vases or beer bottles, on or near the

device.

• Notice regarding power disconnection:

To switch the device off and to disconnect it

from the power source the power plug must

be removed from the power socket. For this

reason the device should be placed in a position

where a constant unobstructed access to the

power socket is assured, thus in an emergency

situation you are able to immediately pull out

the power plug. To eliminate the risk of re you

must completely disconnect the power plug

from the power socket after the device has

been used.

• Always grasp the power cord by the plug. Do

not pull on the cord itself and never touch the

power cord with wet hands as this could result

in a short circuit or an electrical shock. Do not

place the device, speaker cabinets or anything

else on the power cord and make sure that it

does not become clamped. Place the power

cord in a position where it can not be trod

on. A damaged power cord can cause a re

or an electrical shock. Check the power cord

from time to time. Should it become damaged

contact our customer service centre to have it

replaced.

• Never manipulate the power cord of the plug. If

a power cord is provided with an earth lead, this

is mandatory to ensure safe operation!

 Riskofre!

• NEVER leave the device unattended while it is

switched on.

• Never cover the ventilation slots of the device

while it is switched on. Avoid placing this device

in locations that provide insufcient ventilation

or hot locations and do not place the device

in direct sunlight or under strong articial

light sources. Otherwise, it may overheat and

become irreparably damaged.

• Do not operate or store the device in hot

locations or near heat sources like stoves,

radiators or the like.

• Do not place any open sources of re, like

candles, on the device.

• When a thunderstorm with the risk of lightening

threatens please disconnect the device from

the mains power.

Risk of personal injury!

• Keep the power cord and device away from

children. Children frequently underestimate

the dangers of electrical equipment.

• Ensure a safe location for the device.

• Do not operate the device if it has sustained a fall or

is damaged. Arrange for the device to be checked

and/or repaired by qualied technicians.

WARNING:

This symbol, wherever it appears,

alerts you to the presence of

uninsulated dangerous voltage inside

the enclosure - voltage that may be

sufcient to constitute risk of shock.

This symbol, wherever it appears,

alerts you to important operating

and maintenance instructions in the

accompanying literature. Read the

manual.

QUICK SETUP

1. Make sure your unit is off. Preferably remove

the AC power cable.

2. Connect your required output device to the XO-

231’s input connector. Commonly, this would

be a mixer’s auxiliary or main output.

3. Connect all of your required input devices to

the device’s output connectors. Commonly

this would be ampliers or active speakers/

subwoofers.

4. Set the mode button on the rear to your needs.

There are two modes total: 2-way stereo and

3-way mono.

5. Turn your devices on in this order: instruments,

mixer, signal processors (including the XO-

231), amps/speakers.

OPERATING THE XO-231

As the XO-231 runs in a variety of different

modes, we have separated this user’s manual by

these different modes and highlighted the control

elements pertaining to each mode as to help

better make the distinction between critical.

Note: on the rear of the device, the labels located

above or below any of the connectors refer to

different crossover modes available. Ensure the

MODE switch and the corresponding connectors

are properly congured as to prevent damage

occurring to your speakers.

XO-231 • USER’S MANUAL

2-WAY STEREO OPERATION

Set the XO-231 to 2-way stereo by ensuring the

XO-231 • USER’S MANUAL

APPLICATION

Measurement & Setup Tools

By using a hand-held spectrum analysing tool

along with pink noise, users are able to better

perfect their system’s sound. Check the operation

manuals for your analyser and pink-noise

generator for many more useful tips on set up.

Play the pink noise through your system and

stand about 5 meters from your speaker to take

measurements with the spectrum analyser.

Setting Input Levels

The input level can be cut and boost by up to 6

dB. Provided the output level of your mixer is set

to an acceptable degree, setting all input controls

to 0 dB should be perfectly acceptable. In the

event that the device you connect to the XO-231’s

input is a consumer level device (i.e. signal level

is as low as -10dBV), using the full amount of

boost that the input level control allows may be

necessary.

Setting Output Levels

Output levels of each individual band can be cut

and boost by up to 6 dB. With the help of an

analyser, all output levels can be set to achieve

a linear frequency response in the system. First

mute each output, leaving the one you wish to

set active, and check crossover frequencies and

levels by playing pink-noise through your system.

Then, when switching on an adjacent band, the

level measured at the crossover frequency should

immediately go up by 3 dB. This can then be

repeated for all output channels.

Setting the Crossover Frequency

The rst thing to keep in mind when setting your

crossover is what frequencies can my speakers

handle? Be sure to check your subwoofer, full-

range speaker or driver’s user’s manual before

setting your crossover frequencies. Keeping the

signal sent to the speaker in the frequency range

ascribed in the user’s manual will ensure your

speakers function smoothly and correctly.

The Linkwitz-Riley lter employed by the XO-231

employs a slope of 24 dB per octave. It may be

interesting to note that, due to the Crossover

Frequency Button on the rear of the device, the

crossover frequency for the low frequency band is

adjustable between 44Hz and 9.3 kHz. This allows

for the low output to be used with full-range

speakers as well as subwoofer speakers.

Subwoofer Output

The XO-231 features an individual subwoofer

output that runs whether in stereo or mono

operation. The subwoofer output, featured in

addition to the low frequency output, allows

exceptionally loud and deep bass to be played

through your system. The subwoofer signal is a

combined mono signal of the channel 1 and 2

input signals.
