P ge
The AT312 Attuned Top is a co-axial point-source cabinet for
medium to short distance coverage where 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 Subwoofer or
ZV28 Profundo Sub, the result is an extremely high-resolution 4-way active
loudspeaker system with virtually unparalleled resolution and dynamic
power for its size. Its driver compliment incorporates dual 12” woofers in a
vented enclosure for low frequencies and a 12” midrange driver in a sealed
enclosure with a co-axially mounted 1.4” exit compression driver. Coverage
is 80 degrees conical. One-man set up of a substantial system is made easy
because the AT312 cabinets weigh only 88 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 loudspeaker behaves
as a point-source, which deliver more consistent off-axis performance than
conventional loudspeakers with separate mid and high frequency drivers.
This feature enhances resolution and the consistency also enhances the
loudspeaker's versatility, allowing it to be mounted horizontally or vertically
with no compromise in coverage or performance. 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 4-way active loudspeaker system.
The simplicity and ease of these components together, coupled with fidelity
and reliabilty that are industry leading,will delight anyone who is regularly
moving gear.
Any speaker that has the tweeter horizontally or vertically offset from the
mid-frequency driver produces very different response as one moves through
its coverage area from the tweeter side to the woofer side.This is due to the
different distances the sound has to travel to reach the ears. Due to the
co-axial construction of the AT312 the path length difference between lows
and highs is the same in any direction, allowing extremely consistent off-axis
response regardless of which direction you move away from directly on center.

SAFETY INFORMATION
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 SP ) 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: oudspeakers 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 BASSBOSS support if the product is not functioning properly.
BASSBOSS 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.
IMPORTANT NOTES
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.

SET UP INSTRUCTIONS
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 supplie . WARNING: Severe amage
will result if over 140V is applie while switch is in 115V position. If the voltage selection switch is in 230V position an 115V line voltage
is applie , no amage will occur however the unit will not power on.
5. Check that the Power switch is in the OFF 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 ON 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 NOT 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 A en um:
hen 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.

TROUBLESHOOTiNG
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) ED 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 ED is on, check the following:
Is the green “signal present” ED (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 ED 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 SE ) 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 ED will illuminate
at the presence of any signal so while high-frequency signal will illuminate the ED on a
subwoofer, no or very little sound will be heard.
