Important Safety Precautions
Please note: Denon Professional and inMusic are not responsible for the use of its products or
the misuse of this information for any purpose. Denon Professional and inMusic are not
responsible for the misuse of its products caused by avoiding compliance with inspection and
maintenance procedures.
Installation
• Always install subwoofers in accordance with applicable electrical and building codes.
• Install the subwoofer according to its maximum weight. Check the specifications of your
stage to ensure it can support the subwoofer's weight. Also, observe all safety
precautions specified by the manufacturer.
• Do not mount multiple subwoofers on the same stand or pole.
• Always verify that the stand or pole is on a flat, level, and stable surface. Also, fully
extend the legs of tripod-style stands, and ensure its legs do not present a trip hazard.
• 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 subwoofer'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.
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
0.50 110 Airport
0.25 or less 115 Rock concert

Bluetooth Pairing
About Range: Delta Series subwoofers use an advanced, extended-range Bluetooth antenna
design, allowing for ranges far greater than traditional Bluetooth devices. The typical range is
approximately 100 feet (30 meters) with a clear line of sight. However, the range may vary
depending on your source device and the environment.
To maximize the range:
• Set your source device on a flat surface and make sure there are no obstacles between
the subwoofer and your device (e.g., walls, furniture, etc.).
• Turn off your source device's Wi-Fi.
• Turn off any unneeded 2.4 GHz devices in the nearby vicinity (e.g., other Bluetooth
devices, baby monitors, Wi-Fi access points, microwave ovens, etc.).
• Try using a different Bluetooth source device (iPad, iPhone, or iPod touch). Bluetooth
signal strength varies between different devices.
To pair the speaker to your Bluetooth device:
1. Do this on one subwoofer only: With the subwoofer powered on, press and release its
Pairing Button. Its Pairing LED will flash.
2. From your Bluetooth device's settings page, enable Bluetooth and select Denon
Professional as the device. When paired successfully, the Pairing LED will light
continuously. (This process may take up to 30 seconds.)
Important: If your device prompts you to enter a PIN code to pair it to the speaker, enter
0000 (four zeros).
3. Once your device is paired to the subwoofer, the subwoofer will remember the device
even after power-cycling the subwoofer. If the device does not reconnect automatically,
go to your device's Bluetooth settings page and select Connect to reestablish the
connection.
To erase all previous pairing settings, press and hold the Pairing Button for 10 seconds. The
LED will flash to confirm the pairing records are erased. Now, you can pair to a new device.

Features
Rear Panel
1. Power Input: Use the included IEC power
cable to connect this input to a power
source.
2. Fuse: If the unit's fuse is broken, lift this
tab to replace the fuse. Replace it with a
fuse with an 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: Use this switch to power
the subwoofer on or off.
4. Power/Standby LED: This LED illuminates
when the subwoofer is powered on.
5. Standby On/Off Switch: By default, this
subwoofer has its Standby Mode enabled:
when no incoming audio signal is detected
for approximately 15 minutes, the
subwoofer will enter a low-power state.
The subwoofer will exit Standby Mode within 0.5 seconds of detecting an incoming audio signal. Change this
recessed switch's setting to the Off position to disable this feature.
6. Logo On/Off Switch: Press this to turn the light in the Denon Professional logo on or off.
7. Polarity Switch and LED: Press this switch to toggle the polarity of the subwoofer's acoustic output. In some
cases, reversing the polarity can help reduce any interference in the frequency overlap between the subwoofer
and main loudspeaker. When the LED is off, the subwoofer is set to its default positive polarity (the
recommended setting when used with Delta Series loudspeakers). When the LED illuminates red, the
subwoofer's polarity is reversed from its default.
Important: When using multiple Delta Series subwoofers, make sure they are set to the same polarity to avoid
cancellation of the bass frequencies.
8. Inputs: Use a standard XLR or 1/4" (6.35 mm) cable to connect your audio source to this input. This input
accepts line-level sources only.
9. Input Volume Knob: Use this knob to set the level of the audio going into the inputs. The Delta 18S is
engineered to work seamlessly together with Delta 10, Delta 12, or Delta 15 loudspeaker models.
For optimal bass balance, set the Delta 18S input volume knob to the 12 o'clock-position detent, and set the
Delta 10, Delta 12, or Delta 15 volume knobs to their maximum clockwise position. Adjust the volume controls
as needed to further fine-tune the audio level from each system.
When connecting to the output of a pro audio mixer or signal processor, we recommend setting this to the
0 dB setting; the Delta Series subwoofer's gain structure is optimized for standard XLR or 1/4" (6.35mm)
maximum signal levels of +10 dB RMS/continuous (+20 dB peak) from your source. Such devices include live
sound audio mixers, rack mount signal processors, DJ mixers, etc.
10. Signal/Limit LED: This LED illuminates green when an incoming audio signal is detected. It illuminates red
when the audio signal level is too high and is being dynamically reduced to protect the subwoofer from
damage or distortion. If this LED is continually illuminated red, or if the audio output sounds excessively
distorted, then reduce the volume of the connected audio source, or reduce the setting of the Input Volume
Knob.
11. Outputs: Use a standard XLR cable to connect this balanced output to the input of a Delta Series
loudspeaker. Audio is sent from this output at 0 dB.
12. Crossover Bypass Switch and LED: Press this switch to toggle between Standard and Bypass Modes.
When the LED is off, the subwoofer is in Standard Mode (the default) where the XLR outputs' signal is highpass-filtered to be sent to a full-range loudspeaker. When the LED illuminates green, the subwoofer is in
Bypass Mode where the XLR outputs' signal will be unfiltered and full-range (the XLR outputs effectively
function as loop-through connectors in this case).
13. Ground Switch: Engage (depress) this switch to reduce hum or noise.
14.
DSP Mode Button: Press this button to cycle through the subwoofer's internal low-pass crossover DSP
settings, as shown on the rear panel. The LED next to the setting will illuminate when selected. For most
applications, we recommend using the 80 Hz or 100 Hz setting; use the 120 Hz or 140 Hz settings to increase
mid-bass impact.
15. Pairing Button and LED: Press and release this button to pair the subwoofer to your iPad, iPhone, or iPod
touch. The Pairing LED will illuminate when it is paired. See the Bluetooth Pairing section for instructions.

Instalación
• Instale siempre los subwoofers 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 subwoofers en el mismo soporte o columna.
• Verifique siempre que el soporte o columna esté sobre una superficie plana, nivelada y
estable. Asimismo, extienda totalmente las patas de los soportes tipo trípode y
asegúrese de que las patas no representen un riesgo de tropiezo.
• 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.
Nivel de sonido
La exposición a niveles muy altos de ruido puede causar pérdidas auditivas permanentes. La
Administración de Seguridad y Salud Ocupacional de EE.UU. (OSHA) ha especificado los
niveles de exposición permisibles a ciertos niveles de ruido. Según la OSHA, la exposición a
niveles de presión sonora (SPL) elevados que excedan estos límites puede causar pérdidas
auditivas. Cuando utilice equipos capaces de generar SPL elevados, use protecciones
auditivas mientras dichos equipos están en funcionamiento.
