SECURITY AND T E ENVIRONMENT
ELECTRICAL SECURITY
Check that the current in the mains connection where the machine is to be installed corresponds to the
power supply of the machine.
To avoid damaging the equipment, electrical shocks, fire or physical injury when you connect or disconnect
the equipment from the power supply, pull the plug firmly out of the mains socket holding the plug, never the
cable.
Always do this with dry hands.
Keep the power supply cable far from sources of heat. Do not put heavy objects on top of it or change it.
Clean dust and dirt off the power supply cable regularly.
Do not open the machine; you could get an electric shock.
CAUTION
While installing the machine, make sure it is switched off and unplugged.
Do not open the machine. Touching the internal parts is dangerous and you could receive an electric shock.
The machine must not be splashed or dripped on. Never place recipients with liquid inside on the machine.
Do not place anything inside the machine.
LOCATION
Place the equipment on a horizontal surface with enough space around it to allow ventilation.
Avoid direct sunlight, heat sources and excessive dust.
Do not place the machine near magnetic fields or static electricity.
Do not use surfaces which vibrate or receive impact.
Do not pile machines on top of one another.
VENTILATION
Never block or cover the ventilation slits on the machine.
Do not expose it to direct sunlight or place it near sources of heat.
PERIODS OF INACTIVITY
When the machine is not going to be used for a long period of time, disconnect it from the mains.
If you are using an adapter, take into account that it will continue using electricity even if the machine is
switched off. If it is not going to be used for a long period of time, disconnect it from the mains.
T E ENVIRONMENT
To save energy, switch the machine off when you are not going to use it for a long time. The machine could
contain substances that are harmful to the environment or human health. To minimize the effect of these
substances the machine must be correctly managed and recycled when you decide to dispose of it.
When you dispose of it remember: it cannot be thrown into a conventional rubbish bin.
If it contains or uses batteries, these must be disposed of separately.
The machine (without batteries) must be disposed of correctly. Put it in a container specially intended for the
collection of electronic and electrical appliances, at the dump or hand it over to the dealer when you purchase
similar equipment, so that the dealer can dispose of it correctly (at no added cost).

DESCRIPTION
- 3-way stereo active crossover frequency divider with subwoofer.
- Audio signal control with individual adjustment of the gains level of the filter in each way (bass, mid, treble
and subwoofer), as well as the frequency cutoff of the subwoofer filter and the mid-bass and mid treble
filters.
- Independent subwoofer output.
CONTROLS AND FUNCTIONS
FRONT PANEL
1.- PO ER: on/off switch.
Note: always switch the unit on before the amplifier and switch it off afterwards, to avoid damaging the
loudspeakers.
2.- CHANNEL 1: channel 1 controls.
3.- SUB OOFER: subwoofer output channel controls.
4.- CHANNEL 2: channel 2 controls.
5.- LO -MID XOVER FREQ: simultaneously adjusts the cutoff frequency for the bass low pass filter and
the lower cutoff frequency for the mid band-pass filter. The cutoff frequencies can be selected from
between 70 z and 1 k z. The filter slope is 24 dB/octave.
6.- MID-HIGH XOVER FREQ: simultaneously adjusts the higher cutoff frequency for the mid band-pass
filter and the frequency cutoff for the treble high-pass filter. The cutoff frequencies can be selected from
between 480 z and 7 k z. The filter slope is 24 dB/octave.
7.- LO CUT 30 Hz: bass cut off with high pass filter with 30 z cut off frequency with a slope of 12
dB/octave, it is used to minimize problems caused by subsonic signals, to avoid noise and buzzing and
to prevent bass echoes in the loudspeakers.
8.- LO GAIN: bass filter gain control (bass output level).
9.- PHASE: this switch inverts the mid audio signal phase 180°. Normally it is not necessary. owever, in
cases it can be. For example, if you use an XLR connector with inverted polarity and also to compensate
phase cancellation.
Note: before touching these controls, always lower amplifier outputs to avoid damaging the
loudspeakers.
10.- MID GAIN: mid filter gain control (mid output level).
11.- PHASE: this switch inverts the treble audio signal phase 180°. Normally it is not necessary. owever,
in cases it can be. For example, if you use an XLR connector with inverted polarity and also to
compensate phase cancellation.
Note: before touching these controls, always lower amplifier outputs to avoid damaging the
loudspeakers.
12.- HIGH GAIN: treble filter gain control (treble output level).
13.- SUB GAIN: sub-bass filter gain control (sub-bass output level).

14.- LO CUT 30 Hz: bass cutoff with a high pass filter 30 z cut off frequency and a slope of 12 dB/octave,
it is used to minimize problems caused by subsonic signals, to avoid noise and buzzing and to prevent
bass echoes in the loudspeakers.
15.- SUB XOVER FREQ: adjust the sub-bass low pass filter cut off frequency. The cut off frequency can be
selected from between 50 and 250 z. The filter slope is dB/octave.
BACK PANEL
1.- INPUT: audio source input, XLR and 6.3 mm jack connectors.
2.- HIGH: treble output, XLR.
3.- MID: mid output, XLR.
4.- LO : bass output, XLR.
5.- OOFER: balanced subwoofer output, XLR.
6.- Power supply fuse holder. If the fuse blows, check possible causes and replace it for one with the same
characterisitcs.

CONNECTION
Switch off all the equipment and disconnect it from the mains before making any connections.
Connect the audio source to the frequency divider input (using the XLR input or the 6.3 mm stereo jack input),
normally it will be the signal from a mixer.
Adjust the filter parameters in accordance with the audio system characteristics.
In the following example you can see a 3-way stereo system plus subwoofer, although it is also possible to
just use the subwoofer output or set a 2-way system using only the bass and treble outputs and equalling
the bass-mid and mid-treble cut off frequency.
In a 3-way stereo system with subwoofer we will connect each frequency divider output to the corresponding
power amplifier and its respective loudspeakers. The subwoofer output will be connected to the sub-bass
amp (mono) that powers the subwoofer, the bass output to the bass amp (stereo), the mid output to the mid
amp (stereo) and the treble output to the treble amp (stereo). Each amp will power its corresponding
loudspeakers.
