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.

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:
•
TRS Tip: signal positive (+)
•
TRS Ring: signal negative (–)
•
TRS Sleeve: signal ground (shield)
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.

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.
