Let's take a look at the conventional approach to wave guide design
0:05
versus QSCs Diractivity Matched Transition. Let's start with the conventional loudspeaker approach
0:10
Different woofers carry different converage angles. The problem is- most manufacturers
0:14
The problem is- most manufacturers don't match the pattern of the high-frequency device
0:19
with that of the low-frequency device.
0:28
as a result, listeners won't hear the balanced response if they're outside the sweet spot
0:33
In out sample performance venue, this means that listeners who are horizontally off axis
0:39
Will miss out on the critical section of the mid-range
0:40
which is responsible for the intelligibility of the vocals
0:43
the man sitting in the sweet spot is enjoying full audio spectrum
0:48
While the gentleman outside the sweet spot is struggling to understand the vocals
0:52
Now, let's look at QSCs DMT approach to coverage
0:55
DMT matches the coverage of the high-frequency and low-frequency devices at the corssover point
1:04
As a result, the critical vocal range remains far more uniform across the coverage area
1:09
Now the two gentleman in out venue are enjoying the same audio experience
Tips and Definitions
QSC’s DMT ™ Advantage: DMT matches the natural high-frequency coverage angle of the woofer to the compression driver at crossover frequency.
Midrange won’t dropout at the crossover point: KLA’s smooth transition from LF to HF provides consistent audience coverage and power response across the listening plane. The critical mid-range frequencies found in vocals and solo instruments don’t get lost on the edges!
The Result: This provides smooth coverage across the intended listening area. Your audience hears the full frequency spectrum of the program.
