Important Safety Precautions

Please note: Alto Professional and inMusic are not responsible for the use of its products or the

misuse of this information for any purpose. Alto Professional and inMusic are not responsible
for the misuse of its products caused by avoiding compliance with inspection and maintenance
procedures. Please also refer to the included safety and warranty manual for more information.

Caution: To reduce the risk of electric shock, do not connect the subwoofer to a power
outlet while the grille is removed.

Stand-Mounting

• Always install subwoofers in accordance with applicable electrical and building codes.

• Install the subwoofer according to its maximum weight. Check the specifications of your

stand or pole to ensure it can support the loudspeaker’s weight. Also, observe all safety
precautions specified by the manufacturer.

• Do not mount multiple loudspeakers on the same stand or pole.

• Always verify that the stand or pole is on a flat, level, and stable surface.

• Inspect the stand (or pole and associated hardware) before each use and do not use

equipment with worn, damaged, or missing parts.

• Always be cautious in windy, outdoor conditions. You may need to place additional weight
(e.g., sandbags) on stand’s base to improve stability. Do not attach banners or similar
items to any part of a loudspeaker system. Such attachments could act as a sail and
topple the system.

• Unless you are confident that you can handle the loudspeaker’s weight, ask another
person to help you lift it onto the stand or pole.

• Make sure your cables are out of the way of performers, production crew, and audience so
they will not trip over them, pulling the loudspeaker off the stand or pole.

Sound Level

Permanent hearing loss may be caused
by exposure to extremely high noise
levels. The U.S. Occupational Safety and
Health Administration (OSHA) has
specified permissible exposures to
certain noise levels. According to OSHA,
exposure to high sound pressure levels
(SPL) in excess of these limits may result
in hearing loss. When using equipment
capable of generating high SPL, use
hearing protection while such equipment
is under operation.

Hours per day SPL (dB) Example
8 90 Small gig
6 92 Train
4 95 Subway train
3 97 High level desktop monitors
2 100 Classical music concert

1.5 102 Riveting machine
1 105 Machine factory

0.5 110 Airport

0.25 or less 115 Rock concert

Features

Rear Panel

1. Power Input: Connect the included power cable to
this input and connect the other end of the cable to a
power source. Make sure the Power Switch is set to
off when plugging and unplugging the cable.

2. Fuse: If the unit’s fuse is broken, power off the
subwoofer and disconnect it from the power outlet,
and then lift this tab to replace the fuse. Replace it
with a fuse that has the appropriate rating (printed
under the unit’s power cable input). Using a fuse with
an incorrect rating can damage the unit and/or fuse.

3. Power Switch: Turns the subwoofer on/off. Make sure
the Volume knob is set to “zero” before turning it on.

4. Power LED: Illuminates when the subwoofer is on.

5. Outputs: Use standard XLR cables to connect these
outputs to a loudspeaker. The audio signal with
frequencies above the subwoofer’s crossover frequency
will be sent out of these outputs. 1 is the left output, and
2 is the right output.

6. Inputs: Use a standard XLR cables (not included) to
connect your sound source to these inputs. 1 is the left
input, and 2 is the right input.

7. Volume: Turn this knob to adjust the subwoofer’s
output volume.

8. Signal/Limit LED: This LED lights up green when an audio signal is sent to the
subwoofer—it flashes at lower levels and lights solidly at higher levels. The LED lights up
red when output limit/protection is active—if the LED is lit red continuously, reduce the
volume of your audio source.

9. Polarity Reverse Selector: Press this switch to reverse the phase of the subwoofer’s
output. Use this to reduce phasing or cancellations caused by the subwoofer’s location in
a listening space (low-frequency signals have longer wavelengths, which can cause these
unwanted effects).

Important: This affects the signal going to the subwoofer’s amplifier only, not the signal
sent to the outputs.

10. DSP Output Mode: Press this switch to toggle between six settings that adjust delay,
crossover frequency and the level of the XLR outputs. The first four settings are specifically
tailored to the Alto Professional TS308, TS310, TS312, and TS315 full-range loudspeakers.
The last two settings may be useful with non-Alto Professional loudspeakers. When a
setting is selected, its corresponding LED will be lit. See Operation > DSP Output Mode
for more details.

Note: The subwoofer will always play frequencies below its crossover frequency, regardless
of the position of this switch.

11. Extended LF: Press this switch to enable or disable the extended low-frequency response
of the subwoofer. When enabled, the corresponding LED will be lit, and the lower
frequencies of the subwoofer will be boosted.

Note: If this function is enabled, make sure that the subwoofer’s extended frequencies do
not cause any phasing or cancellation if they overlap with your loudspeakers’ frequencies.

Operation

DSP Output Mode

For precise signal adjustment, Alto Professional TS3 subwoofers employ Digital Signal
Processing (DSP). This feature gives you a cleaner, more accurate sound. The DSP controls
EQ, distortion detection/limiting, crossover frequency and signal delay with virtual perfection—
and without the production variability inherent in analog filtering. Simply stated, DSP takes an
analog signal, converts it to digital and then performs all the desired modifications and
adjustments in the digital realm, where it’s totally free from the inaccuracies and susceptibility
to added noise that plague analog signal processing. DSP is a major reason why Alto
Professional subwoofers are so clean, dynamic and versatile.

The DSP Output Mode switch on the rear panel of your
subwoofer toggles between six settings that adjust
delay, crossover frequency and the level of the XLR
outputs. This feature optimizes your speaker system
performance while also simplifying your full-range
speaker + subwoofer setup. If you have an Alto
Professional TS3 loudspeaker, using the correct setting
will allow your loudspeaker and TS3 subwoofer to be
time-aligned, crossed over at the ideal frequency and
level-matched.

Press the DSP Output Mode switch to select between the following settings:

• TS308: Matches your TS3 subwoofer with the Alto Professional TS308 full-range speaker.

• TS310: Matches your TS3 subwoofer with the Alto Professional TS310 full-range speaker.

• TS312: Matches your TS3 subwoofer with the Alto Professional TS312 full-range speaker.

• TS315: Matches your TS3 subwoofer with the Alto Professional TS315 full-range speaker.

• High Pass: Employs a 100Hz crossover frequency with no delay or level adjustments. This

setting works quite well with a wide variety of non-Alto Professional speakers.

• Bypass: Bypasses the DSP functions (there will be no crossover, delay or level
adjustments). This setting is ideal for daisy chaining subwoofers.

Once you have selected a setting, the corresponding LED will be lit.

Please Note:

• For the TS308, TS310, TS312 and TS315 options, the system is level-matched when the
Volume control for TS3 subwoofer and TS3 full-range speaker are set to 0dB (12 o’clock).
This simplifies your setup and elevates the overall system performance.

• If you do not have Alto Professional TS3 full-range speakers, you can still use the first four
DSP settings for your existing speakers. Cycle through the six options to find the best
sound and then make any level adjustments that are needed.

Montaje en soporte

• Instale siempre los altavoces de acuerdo con los códigos de electricidad y construcción aplicables.

• Instale el subwoofer de acuerdo a su peso máximo. Compruebe las especificaciones de su

soporte o columna para asegurarse de que pueda soportar el peso del subwoofer. Asimismo,
observe todas las precauciones para la seguridad especificadas por el fabricante.

• No monte varios altavoces en el mismo soporte o columna.

• Verifique siempre que el soporte o columna esté sobre una superficie plana, nivelada y estable.

• Inspeccione el soporte (o columna y elementos de fijación asociados) antes de cada uso y no

utilice equipos con piezas desgastadas, dañadas o faltantes.

• Tenga siempre cuidado en condiciones de viento a la intemperie. Es posible que deba colocar
peso adicional (como bolsas de arena) en la base del soporte para mejorar la estabilidad. No fije
pancartas o elementos similares a ninguna parte del sistema de altavoces. Tales agregados
pueden funcionar como velas y hacer volcar el sistema.

• Salvo que tenga confianza de que puede manejar el peso del subwoofer, solicite a otra persona
que le ayude a levantarlo para colocarlo en el soporte o columna.

• Asegúrese de que los cables estén fuera del camino de los intérpretes, personal de producción y
audiencia, de modo que no tropiecen con ellos y hagan caer el subwoofer del soporte o columna.

Nivel de sonido

La exposición a niveles muy altos de ruido
puede causar pérdidas auditivas
permanentes. La Administración de
