Features
Woofer: The woofer unit is 8 inches (203 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 BX8 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 BX8 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 60 Hz.
Enclosure: Like the other components, the BX8 D2's enclosure has an important role in shaping the overall sonic response. In order to provide more stable performance, the BX8 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 BX8 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 BX8 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.

Unbalanced 1/4" wiring can be done with either a twoor 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.

Installation
For optimal performance of the BX8 D2, please read the following thoroughly and carefully prior to installation.
Precautions
•Handling: Please do not touch the speaker cones. The BX8 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 BX8 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 BX8 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 BX8 D2 and turn the volume of the BX8 D2 down to a minimum before making the necessary connections.

XLR Balanced Connection
Assure that the power switch of the BX8 D2 is turned off and that the volume control of the BX8 D2 is turned down to a minimum. Connect the male end of an XLR balanced cable to the balanced input of the BX8 D2 (refer to the following diagram for balanced connection).
TRS Balanced/Unbalanced Connection
Assure that the power switch of the BX8 D2 is turned to off and that the volume control of the BX8 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 BX8 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 the speakers is one of the most important procedures in order to monitor sound accurately. To monitor with the BX8 D2s performing to their maximum capability, an appropriate listening environment and correct placement are required. Please refer to the following for correct BX8 D2 placement.
1.The two units 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 BX8 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 BX8 D2s.

Características
Woofer: El woofer tiene un diámetro de 8" (203 mm) y está formado por un cono de Kevlar protegido magnéticamente, una bobina de alta temperatura y un aro amortiguador de goma. El woofer del BX8 D2 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 BX8 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 BX8 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 BX8 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 BX8 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 BX8 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 BX8 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.

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.
