The BX5 D2 was designed and tested by veteran audio engineers to meet your needs in a
studio monitoring environment. It is focused on the functional goal of delivering pure, original
sound without any additional coloration. The BX5 D2 monitor is self-powered, directly accepting
a line-level signal from a variety of sources.
The Studiophile BX5 D2 is designed to overcome all the limitations of conventional studio
reference monitors within the digital audio environment. This system delivers a wide-range
frequency response by employing two extraordinary drivers and unique crossover technology
licensed by M-Audio. It boasts a stable and balanced low-mid frequency response along with a
defined mid and high frequency response as well. Both drivers are magnetically shielded for
desktop music production.
For pro engineers at commercial studios to home studio owners, the Studiophile BX5 D2 sets a

Features
Woofer: The woofer unit is 5 inches (127 mm) in diameter with a magnetically shielded Kevlar
cone, high-temperature voice coil and damped rubber surround. It is designed to deliver
balanced mid and low-frequency response. M-Audio's new BX5 D2 employs Kevlar for lowfrequency driver construction. The same material used in bullet-proof vests, Kevlar's high
resilience makes it ideal for use in speaker cones—although it is typically reserved for monitors
with higher price tags than the BX5 D2. Needless to say, Kevlar represents a significant
improvement over the polypropylene and paper used in most monitors at this price.
Tweeter: By employing a specially developed 1-inch (25 mm) silk dome with magnetic
shielding, the tweeter can deliver distortion-free original sound and offer an extremely natural
response. Its design minimizes reaction time by using a specially shaped silk dome for
excellent delivery, and also minimizes resonance by adapting a unique internal damping
technology.
Sub-Frequency Port: The air vent hole in the rear panel is called a Sub-Frequency Vent Port
and is designed to allow the discharge of extremely low frequencies occurring below 60Hz.
Enclosure: Like the other components, the BX5 D2's enclosure has an important role in
shaping the overall sonic response. In order to provide more stable performance, the BX5 D2's
enclosure employs a special high acoustic efficiency MDF and unique interior reinforcement
designed to absorb vibration and impact generated under extreme conditions. The custom
design on the front panel will aid in diffraction and will benefit stereo imaging.

Network and Power Amplifiers: The active crossover network and power amplifiers for the
BX5 D2 are specially designed for its woofer and tweeter. The network properly distributes low,
mid, and high frequencies to the driver components in order to reduce distortion and loss of
sound, thus achieving a naturally balanced sound.
In order to generate powerful, ultra-crisp sound, there are two separate power amplifiers inside
the BX5 D2 for driving the woofer and tweeter separately in a high-end bi-amp structure. The
power delivered to the woofer driver at a low-rated distortion is 40 W, and 30 W is also
delivered to the tweeter.
Rear Panel
1. XLR Input: This jack accepts XLR input
connections with either balanced or
unbalanced wiring. The input wiring of an
XLR connector should be as follows:
• XLR Pin 1: signal ground (shield)
• XLR Pin 2: signal positive (+)
• XLR Pin 3: signal negative (–)
2. TRS Input: This jack accepts 1/4"
connections with either balanced or
unbalanced wiring. For balanced wiring, a
three-conductor TRS plug is necessary.
The input wiring of a TRS connector
should be as follows:
Unbalanced 1/4" wiring can be done with
either a two- or three-conductor (TS or
TRS) plug. A two-conductor (TS) plug automatically grounds the signal negative input,
whereas a three-onductor (TRS) plug, wired unbalanced, provides the option of leaving
the negative input open or grounded. We recommend that you ground the unused
negative input (this can be done by wiring the ring and sleeve of the TRS plug together).
The TRS input is summed through a balanced input amplifier with the XLR input, allowing
both inputs to be used simultaneously. Input specifications apply to both.
3. Product Specification: This label contains the model and specification information.
4. Sub-Frequency Vent Port: This port aids in reproduction of very low frequencies by
discharging frequencies below 60 Hz.
5. Volume Control: Use the volume control to set the output sound pressure from the BX5
D2 to proper levels as required.
6. Power Switch: This switch turns the monitor on and off.
7. Power Receptacle: Accepts a detachable 3-circuit line cord in order to power the monitor.
8. Fuse Holder: Holds the external main fuse.
9. Voltage-Select Switch: Provides two selections, 115V AC and 230V AC, and should be
set to match the "house supply" (receptacle) voltage of the country or location in which the
speaker is used. The 115V setting is correct for the USA, while the 230V setting is correct
for most of the UK and Europe.

Installation
For optimal performance of the BX5 D2, please read the following thoroughly and carefully prior
to installation.
Precautions
•Handling: Please do not touch the speaker cones. The BX5 D2 set is packaged in the box
tightly, so your attention is required when taking the monitors out of the box. To avoid
possible damage to the speaker units, hold both sides of the monitor in order to pull it out
of the box. The speaker cones should not be touched in order to avoid damage even after
they are out of the box.
•Correct Power Operation: Since the BX5 D2 contains its own amplifier, it must be
connected to a power outlet using the detachable AC cable provided. Before connecting
power, please make sure that the Voltage-Select Switch located on the speaker's rear
panel is set to the appropriate position, as described in the rear-panel features list
appearing earlier in this manual.
WARNING! Use of improper Voltage-Select Switch combinations may result in hazardous
conditions and/or damage to speaker components not covered by speaker warranty.
•Connections: You can connect either an XLR balanced cable or TRS
balanced/unbalanced cable from the input of each BX5 D2 to your corresponding preamp,
computer or game console outputs. We recommend that you use high-quality balanced or
unbalanced cables for input connections. Also, ALWAYS turn off the power of the BX5 D2
and turn the volume of the BX5 D2 down to a minimum before making the necessary
connections.

XLR Balanced Connection
Assure that the power switch of the BX5 D2 is turned off and that the volume control of the BX5
D2 is turned down to a minimum. Connect the male end of an XLR balanced cable to the
balanced input of the BX5 D2 (refer to the following diagram for balanced connection).
TRS Balanced/Unbalanced Connection
Assure that the power switch of the BX5 D2 is turned to off and that the volume control of the
BX5 D2 is turned down to a minimum. Connect the male end of a TRS balanced or TS
unbalanced cable to the TRS input of the BX5 D2 (refer to the following diagram for TRS
connection).
Connecting to Preamp or Computer Outputs
Before connecting, make sure the output device's power has been turned off. Plug the XLR
balanced, TRS balanced or TS unbalanced cable to the corresponding output connectors of a
pre‑amplifier, computer or game console.
Speaker Placement
Placing speakers is one of the most important
procedures in order to monitor sound accurately. To
monitor with the BX5 D2s performing to their
maximum capability, an appropriate listening
environment and correct placement are required.
Please refer to the following for correct BX5 D2
placement.
1. The monitors and the listener should basically
align to form a regular triangle. Refer to the
following diagram.
2. Position the monitors so that the top of the
woofers are level with your ears in a normal
listening environment. Refer to the following
diagram.
3. Place the monitors vertically with the woofer on
the bottom. Placing the BX5 D2 horizontally is
not recommended.
Remarks: DO NOT place any obstacles that may
block the flow of air in front or between the
monitors. Also remove reflective materials such as
glass, mirrors or metal from the monitoring
environment. PLACE THOSE MATERIALS AWAY
FROM THE PATH OF THE SOUND FROM THE
BX5 D2s.

Características
Woofer: El woofer tiene un diámetro de 5" (127 mm) y está formado por un cono de Kevlar
protegido magnéticamente, una bobina de alta temperatura y un aro amortiguador de goma. El
woofer ha sido diseñado para proporcionar una respuesta equilibrada en las frecuencias
medias y bajas. M-Audio ha utilizado Kevlar en la construcción del woofer del nuevo BX5 D2.
Se trata del mismo material utilizado en los chalecos antibalas y, gracias a su elevada
resistencia, es el material perfecto para los conos, aunque normalmente es un material
reservado para los monitores de gamas superiors a la del BX5 D2. Huelga decir que el
rendimiento del Kevlar supera de forma significativa al del polipropileno y papel (materiales
comúnmente utilizados en la mayoría de monitores de este precio.)
Tweeter: Gracias a la cúpula de seda de 1" (25 mm) protegida magnéticamente,
especialmente desarrollada para estos monitores, el tweeter proporciona un sonido limpio,
exento de distorsión y con una respuesta extraordinariamente natural. El diseño del tweeter
contribuye a minimizar el tiempo de reacción y ofrece un rendimiento excelente, al mismo
tiempo que reduce la resonancia gracias a la implementación de una exclusiva tecnología de
amortiguación interna.

Puerto de subfrecias: La salida de aire del panel trasero se denomina puerto de
subfrecuencias. Su misión consiste en descargar frecuencias extremadamente bajas, del orden
de 60 Hz e inferiores.
Gabinete: El gabinete del BX5 D2 juega un papel tan importante como el de cualquier otro
componente, modelando específicamente la respuesta sónica global. Con el fin de ofrecer un
rendimiento más estable, el gabinete del BX5 D2 está fabricado a base de MDF de alta
eficiencia acústica e incorpora un exclusivo refuerzo interno diseñado para absorber las
vibraciones y amortiguar el movimiento en condiciones de operación extremas. El diseño
especial del panel frontal facilitará la difracción y beneficiará la imagen estéreo.
Divisor de frecuencias y amplificadores de potencia: El divisor de frecuencias activo y los
amplificadores de potencia del BX5 D2 han sido especialmente diseñados para el woofer y el
tweeter empleados en su construcción. El divisor se encarga de distribuir adecuadamente las
frecuencias bajas, medias y altas a los distintos componentes, reduciendo la distorsión y las
pérdidas de señal y proporcionando así un sonido natural y equilibrado.
Los monitores BX5 D2 disponen de dos amplificadores de potencia independientes para el
tweeter y el woofer, es decir, cuentan con un sistema biamplificado de alta calidad gracias al
cual proporcionan un sonido de extraordinaria potencia y definición. El amplificador de graves
proporciona una potencia de 40 W a distorsión nominal, mientras que el de los agudos ofrece
una potencia de 30 W.
Panel trasero
1. Entrada XLR: Este conector XLR admite
señales de entrada balanceadas y no
balanceadas. El cableado de la entrada XLR
se realiza de acuerdo con el siguiente
esquema
• Patilla 1: Tierra (Masa)
• Patilla 2: Positivo (+)
• Patilla 3: Negativo (–)
2. Entrada TRS: Este conector 1/4" (6,35 mm)
1
2
admite señales de entrada balanceadas y
no balanceadas. Si desea establecer una
línea balanceada deberá utilizar conectores
TRS (tip-ring-sleeve) balanceados, con
3
cables de tres conductores. El cableado de
la entrada TRS se realiza de acuerdo con el
siguiente esquema:
• Punta: Positivo(+)
• Anillo: Negativo (–)
• Pantalla: Tierra (Masa)
El cableado no balanceado puede realizarse con dos o con tres conductores (TS y TRS,
respectivamente). Si utiliza un conector TS de dos conductores, la señal de entrada
negativa se conecta automáticamente a la masa, mientras que si emplea un conector
TRS de tres conductors soldado en modo no balanceado tendrá la opción de dejar el polo
negativo abierto o conectarlo a la masa. Es aconsejable conectar a la masa la entrada
negativa no utilizada. Para ello basta con unir el anillo y la pantalla del conector TRS.
La señal presente en la entrada TRS se suma a la de la entrada XLR a través de un
amplificador de entrada balanceada, por lo que ambas entradas pueden ser utilizadas de
manera simultánea. Las especificaciones de entrada son aplicables a ambas entradas.
