User Guide (English)
Introduction
The BX8 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 BX8 D2 monitor is self-powered, directly accepting
a line-level signal from a variety of sources.
The Studiophile BX8 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 BX8 D2 sets a
new affordable standard in studio monitoring.

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 low-
frequency 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.

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 (+)                           4
•  XLR Pin 3: signal negative (–)
2.   TRS Input: This jack accepts 1/4"        XLR  Input  Volume

Unbalanced 1/4" wiring can be done with              AC Select  9
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 BX8
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.
