Speakon Outputs

The upper Speakon jack has both Channel 1 and

Channel 2 outputs, so it is especially useful for parallel,

bi-amp, or BRIDGE mono operation. The other Speakon

carries only Channel 2's output. See the illustrations at

above.

Source (INPUT) comes from the output source of the

active/powered speaker while the bridge (OUTPUT)

connects to the passive/non-powered speaker.

A speakon cable is required to connect the “OUTPUT”

of the acive/powered speaker to the “INPUT” of the

passive/non--powered speaker. Please order the speakon

cable from our authorized dealers.

NOTE

Dynamic Fusion Technology™ (DFT)

The Better Music Builder engineers have been working hard

on brining home entertainment to the next level, the experi-

ence that people have been dreaming about but never had

before such as real excitement, freestyle performing, and

intensive hearing are included all in one system. To meet

audience’s expectation, our engineers understand the need to

research and develop the latest technologies. For this reason,

Better Music Builder step developed the Dynamic Fusion

Technology™ (DFT).

DFT practices the latest computer stimulation technology to

design smaller size circuit with better distortion minimization

function. The T share horn is specially designed to facilitate

the composition of array. The woofer uses a 75mm diameter

high-power voice coil with round copper wire, and the layer

is 2 way around the inside and outside. The voice coil frame

material with very high levels of TIL provides excellent strength

and high power capacity, which can boost the speaker

power up to 400W, and the short-term maximum power can

reach up to 1600W. The tweeter with magnalium

diaphragm is made by high-temperature heat treatment

process to maximize damping strength and to reduce

proportion of 3rd harmonic distortion to create more natural,

delicate and nice sound.

DFT is a unique design that integrates in the drivers to

enhance several critical performance parameters: frequency

response, power output, and distortion.

By implementing DFT, engineers understand that the shape of

the pole piece that can affect the magnetic interaction

between the voice coil and the magnetic field, and is

sometimes used to modify a driver’s behavior. A “shorting

ring”, or Faraday loop, may be included as a thin copper

cap fitted over the pole tip or as a heavy ring situated within

the magnet-pole cavity. The benefits are to reduce imped-

ance at high frequencies, providing extended treble output,

reduced harmonic distortion, and a reduction in the induc-

tance modulation that typically accompanies large voice coil

excursions. On the other hand, the copper cap requires a

wider voice-coil gap, with increased magnetic reluctance;

this reduces available flux, requiring a slightly larger magnet

for equivalent performance.

The wire in the voice coil is made of copper, and its cross

section is hexagonal, giving varying amounts of wire volume

coverage in the magnetic gap space. The coil is oriented

co-axially inside the gap; it moves back and forth within a

small circular volume (a hole, slot, or groove) in the magnetic

structure. The gap establishes a concentrated magnetic field

between the two poles of a permanent magnet; the outside

of the gap being one pole, and the center post (called the

pole piece) being the other. The pole piece and back plate

are often a single piece, called the pole plate or yoke.

DFT’s Dynamic Transition Waveguides™ (DTWaveguides)

represents the latest horn technology. In addition to providing

smooth, low distortion sound, DTWaveguides delivers uniform

off-axis frequency response to every point within the intended

coverage area – not just in the horizontal and vertical planes –

resulting in superior array – ability of multiple loudspeaker

systems. PTWaveguides combine outstanding pattern control

with undistorted sound for natural music and intelligible speech.
