This device is intended to be used in a sound reinforcement system. Use the device only as
described in this user manual. Any other use or use under other operating conditions is consid‐
ered to be improper and may result in personal injury or property damage. No liability will be
assumed for damages resulting from improper use.
This device may be used only by persons with sufficient physical, sensorial, and intellectual
abilities and having corresponding knowledge and experience. Other persons may use this
device only if they are supervised or instructed by a person who is responsible for their safety.
DANGER!
Danger for children
Ensure that plastic bags, packaging, etc. are disposed of properly and are not
within reach of babies and young children. Choking hazard!

CAUTION!
Possible hearing damage
The device can produce volume levels that may cause temporary or permanent
hearing impairment. Over an extended period of time, even levels that seem to
be uncritical can cause hearing damage.
Decrease the volume level immediately if you experience ringing in your ears or
hearing impairment. If this is not possible, keep a greater distance or use suffi‐
cient ear protectors.
CAUTION!
Risk of injury due to heavy weight
Due to the heavy weight of the device, at least two persons are required for trans‐
port and installation.

4 Installation
Unpack and carefully check that there is no transportation damage before using the unit. Keep
the equipment packaging. To fully protect the device against vibration, dust and moisture
during transportation or storage use the original packaging or your own packaging material
suitable for transport or storage, respectively.
Establish all connections as long as the unit is switched off. Use the shortest possible high-
quality cables for all connections.
CAUTION!
Risk of injury due to heavy weight
Due to the heavy weight of the device, at least two persons are required for trans‐
port and installation.

NOTICE!
Possible property damage by magnetic fields
Loudspeakers produce a static magnetic field. Therefore, maintain an appropriate
distance to devices that can be adversely affected or damaged by an external
magnetic field.
Use the speaker always having a high-pass filter with a cut-off frequency of at least
70 Hz at a slope of at least 18 dB/oct.

4.1 Tips on handling speakers
We recommend you to set up the speakers in a way, that the sound signals can reach the audi‐
ence unobstructedly. It will often be helpful to mount the speakers on tripods. Thus, the sound
will be evenly spread with maximum range throughout the audience area.
Always use high grade cable to connect your equipment. Otherwise you won't reach max‐
imum sound quality.
For optimum results both impedance and power handling of the speakers must match the
requirements of the amplifier. Always follow the technical specifications of the speakers! The
overall impedance of the connected loudspeakers must not deceed the minimum output
impedance of the amp. The amps max. RMS output power should be 50 % above the power
handling capacity of the connected speakers.
If you notice distortion during operation, either the amp or the speaker is overloaded. This may
permanently damage the amp or the speaker. Always reduce the volume when you hear dis‐
tortion.

4.2 Terminals for wiring ‘Bass to 1’
In order to use the terminals for wiring ‘Bass to 1’, turn the cover of the connector panel so that
the notches are in horizontal position.
1, 2 NL4 terminals, wired in parallel (1+/1– to bass; 2+/ 2– looped-through)
Installation
Achat 212 Sub-LM
15

With this wiring option, you can connect the bass directly using a two-wire cable (wires 1+/1–).
If you are using four-wire cables, you can use heads that receive their signal via wires 2+/ 2–
and loop wires 1+/ 1– through. The bass is connected to wires 1+/1– and loops wires 2+/ 2–
through. The order in which the speakers are wired doesn't matter. Never fall below the min‐
imum load impedance, though.

4.3 Connecting to the Achat system
In order to use the terminals for the Achat system wiring, turn the cover of the connector panel
so that the notches are in vertical position.
3, 4 NL4 terminals, wired in parallel (2+/ 2– to bass; 1+/1– looped-through)
Installation
Achat 212 Sub-LM
17

These terminals allow for easy wiring with four-wire cables, as the heads get their signal via
wires 1+/ 1– and loop wires 2+/ 2– through; the bass is connected to wires 2+/2– and loops
wires 1+/ 1– through. The order in which the speakers are wired doesn't matter. Never fall
below the minimum load impedance, though.
