• Outstanding Sound Quality
• Lightweight and Low-Profile
• Usable Singly or In an Array as a Main or Side-Fill
• Tall, Thin Design Gets Mids and Highs Above Audience
• Permits One Person Set-Up of a emarkable System
The AT312 Attuned Top is a co-axial source array cabinet for
medium to short distance coverage where high output, a small
footprint and very high fidelity are required. It’s compact, simple
to use, easy to set up, attractive and capable of very high output
with superbly uncolored sound and natural musical character.
When combined with subwoofers like the SSP218 Profundo “Dub-ill”
Subwoofer, the result is an extremely high-resolution 4-way active loudspeaker
system with virtually unparalleled frequency response and dynamic power for
its size. Its driver compliment incorporates dual 12” woofers in a vented
enclosure for low frequencies and a 12” closed-back midrange driver with a co-
axially mounted 1.4” exit compression driver coupled to a 40 by 60 degree
horn. The 40-degree horizontal coverage per box allows arrays to be
configured for 80, 120, 160, 200 degrees or more of horizontal coverage. One-
man set up of a substantial system is made easy because the AT312 cabinets
weigh only 86 lbs each.
Dual 12” low frequency drivers were chosen to minimize cabinet frontal area
while delivering the best possible speed and impact in their operating range.
Thanks to the narrow frontal area, the low frequency drivers couple coherently
when multiple cabinets are arrayed, providing powerful mid-bass impact from
a small, lightweight box. The 12” coaxial drivers also serve to minimize frontal
area while maximizing output. The 12” midrange drivers are tightly spaced
and the high-frequency lens is adapted to minimize midrange comb filtering.
The cabinets are built with a 20-degree taper on each side, allowing them to
be tightly packed and maintain the correct 40-degree splay angle to match
the high frequency lens pattern. The 48” tall box elevates the mid and high
frequency radiators to a minimum of 7’6” on center when stacked on the
corresponding subwoofer systems.
Transportation and set-up of the SSP218/AT312 combination is made easy
because the subwoofers serve as a carrier for the tops. In most venues it’s
possible to roll the system into place, lock the casters, tilt up the tops, plug in
the power and signal and have an extremely substantial system ready to play
in a few short minutes by just one person.
When an AT312 is used with a BASSBOSS powered subwoofer the result is
a very effective, practical, high fidelity 3-way active loudspeaker system. In
most venues it’s possible to roll the system into place, lock the casters, tilt up
the tops, plug in the power and signal and be ready to play in a few short
minutes on almost any scale. The simplicity and ease of these components
together will delight anyone who is regularly moving gear, coupled with fidelity
and reliabilty that are industry leading .

SAFE Y INFORMA ION
Read with special attention, as they provide important information. Information regarding use of loudspeakers:
Never stand in the immediate vicinity of loudspeakers driven at a high level. Professional loudspeaker systems are capable
of causing a sound pressure level detrimental to human health. Seemingly non-critical sound levels (from approx. 95 dB
SPL) can cause hearing damage if people are exposed to it over a long period.To prevent potentially dangerous exposure
to high levels of acoustic pressure, anyone who is exposed to these levels should use adequate protection devices.
When a transducer capable of producing high sound levels is being used, it is therefore necessary to wear ear plugs or
protective earphones.
See the manual technical specifications to know the maximum sound pressure level.
In order to prevent accidents when setting up the loudspeakers or loudspeaker stands, make sure they are standing on
a firm surface.
Ensure that all additional hardware, fixings and fasteners used for installation or mobile deployment are of an appropriate
size and load safety factor.
Pay attention to the manufacturers' instructions and to the relevant safety guidelines.
Regularly check the loudspeaker housings and accessories for visible signs of wear and tear, and replace them when
necessary.
Regularly check all load bearing bolts in the mounting devices.
Caution: Loudspeakers produce a static magnetic field even if they are not connected or are not in use.Therefore make
sure when erecting and transporting loudspeakers that they are nowhere near equipment and objects which may be
impaired or damaged by an external magnetic field.
Generally speaking,a distance of 0.5 m (1.5 ft) from magnetic data carriers (floppy disks, audio and video tapes, bank cards,
etc.) is sufficient; a distance of more than 1 m (3 ft) may be necessary with computer and video monitors.
Never attempt to carry out any operations, modifications or repairs that are not expressly described in this manual.
Contact your dealer or BASSB SS support if the product is not functioning properly.
BASSB SS strongly recommends this product is only installed by professional qualified installer who can ensure correct
installation and certify it according to the regulations in force.
The entire audio system must comply with the current standards and regulations regarding electrical systems.
IMPOR AN NO ES
To prevent the occurrence of noise on line signal cables, use screened cables only.All the precautions, in particular the
safety ones, must be and avoid putting them close to equipment that produces high-intensity electromagnetic fields,
power cables and loudspeaker lines.

1. Place loudspeaker in the desired location. Ensure that it is secure and stable.
2. Rotate the input attenuator knob counterclockwise to the lowest setting.
3. Connect signal via the XLR input jack.
4. Check voltage selection switch to ensure it is in the correct position for the AC line voltage being supplied.
WARNING: Severe damage will result if over 140V is applied while switch is in 115V position. If the
voltage selection switch is in 230V position and 115V line voltage is applied, no damage will occur however the
unit will not power on.
5. Check that the Power switch is in the FF position.
6. Connect the amplifier module’s power supply cord using the blue PowerCon™ connectors.To insert, align the
indexing tabs on the Powercon™ connector, insert it into the socket and rotate clockwise until the latch catches.
7. Connect the electrical plug to a power source.
8. Select the desired preset via the PGM SEL button.
9. Turn N the power switch.
10. Check that the MUTE buttons are pressed IN to un-mute the channels.
11. Rotate the input attenuator clockwise to achieve the desired sound level.
The AT312 is equipped with 2 presets. The presets are selected using the PGM SEL button. The button has 2
positions, in for preset 1 and out for preset 2.The presets load into the DSP when the amplifier module is powered
on. Changing the preset select button position while the amplifier is in operation will N T change the setting.To
change the setting, select the position for the desired preset and then power on the amplifier.
Preset 1 includes all the required processing for normal operation. It is recommended that preset 1 be used for initial
setup and under most operating conditions. Preset 2 offers increased high frequency output and is appropriate for
use where greater distances must be covered such as outdoors or in other locations where additional high frequency
content is desirable.
System Setup Addendum:
When connecting multiple loudspeakers in a system, signal can be passed through from one loudspeaker to another
using XLR cables. No processing is applied to the signal as it passes through from the input to the output connectors
in each loudspeaker. Signal can be routed in any sequence because each loudspeaker receives a full-range signal and
applies the necessary processing in order to operate as part of the overall system. It is recommended to run signal
to the nearest box first and patch to the next nearest box in sequence.
The AT312 is equipped with a power pass-through facility that allows multiple boxes to be connected on a single
power source. The total power draw of all units connected through one power input connector cannot exceed
20A.This limits the number of AT312s that can be connected on one power inlet to 2 when using 115V line voltage
and 4 when using 230V line voltage.

If after following the above instructions for setup you have no output from the loudspeakers, please check
the following:
Verify that the green power (PWR) LED is on. If not, check the following:
1. Is the power cord plugged into a live outlet?
2. Is the Neutrik Powercon connector rotated into the locked position?
3. Is the amplifier power switch on?
If the power LED is on, check the following:
Is the green “signal present” LED (SIG) illuminating? If not:
1. Is the signal cable connected to the input?
2. Is the signal cable connected to an operating output at the other end?
3. Is the signal flowing to the input? Check the integrity of the cable.
If the signal LED is illuminating:
1. Is the attenuator turned all the way down or at a very low level?
2. Are the mute buttons engaged?When the button is out, the channel is muted. Make sure that the mute
buttons are pressed IN for normal operation. The mute buttons are next to the program select
(PGM SEL) button.
3. Is the signal flowing to the input full-range? Filters in the signal may remove the operating frequencies
of the loudspeaker receiving them.The signal LED will illuminate at the presence of any signal so while
high-frequency signal will illuminate the LED on a subwoofer, no or very little sound will be heard.
