DB Technologies DVA-S1518N, DVA-S2585N User Manual

DVA bass bins are loaded with state-of-the-art, high-performance subwoofers.
Equipped with powerfull woofers with voice coils with diameters up to 4“, these units‘ load handling

capacity is extremely high, and their transient response is remarkably faithful.

The dual ventilation system minimizes heat buildup and power compression while helping to
maximize loading handling capacity and reliability.

The woofers feature a fiberglass-reinforced diaphragm, an exceedingly robust triple-roll surround,
and a geometrically optimized cone. All this culminates in peak-to-peak excursion capabilities

ranging up to 48 mm.

Subwoofer Systems

These subwoofers are driven by digipro®G2 digital power amps with up to 3000W output.
Digipro®G2 technology is so very efficient that it does not require fans.
With no moving parts to tend to, these amps are altogether maintenance-free.

Equipped with PFC switched-mode power supplies, they are largely impervious to line
voltage fluctuations, which is a tremendous asset in a touring rig.

Our network-enabled DVA subwoofers are designated by an “N” in the product name.

They feature a premium-quality DSP boasting excellent audio specs with variable
crossover frequencies, precise limiter functions and adjustable delay settings for perfect
time alignment.

A special preset makes it easy to set up cardioid systems with enhanced directivity.
Settings are readily adjusted using the rear-mounted rotary encoder. The DSP also

provides an X-Over output for connecting satellites (in stereo on S08 and S09 units).

Factory-equipped with an RDnet port, these subwoofers are ready for integration into
elaborate, remotely controlled and monitored DVA T12 sound reinforcement systems
via RJ45 inputs and outputs that connect the units to the RDnet hub.

Made of sturdy birch multiplex covered in robust black textured lacquer, the subwoofer
housing is fronted with a rugged speaker grille. The enclosure is easy to tote with its
comfortable carrying handles.

Optional dust covers protect it on the go. With 16 threaded bushings each on their
rear panels, the S09, S10, S30N, S1518N, 1521N and S20 bins are ready to accept Blue
Wheels. Retrofitted with the appropriate fly kit, S09, S10, 1518N and 2585N subwoofers
are easily rigged and flown.

DVA S30N Subwoofer, 2x18“ Bassreflex Horn Loaded

Featuring a dual 18“ subwoofer pair ing in a bass reflex housing, the DVA
S30 packs a muscular, ultra lowfrequency punch.

It delivers very powerful performance indeed with a range extending
down to the lowest frequencies.

This sub-bass powerhouse is the perfect addition to large PAs and an
excellent complement to DVA T12 mid-/high-range units in stacked arrays.

Bass reflex horn housing

This sophisticated hybrid design brings together the benefits of bass
reflex and horn systems in a compact housing engineered to render low
frequencies with high SPL.
The two baffle boards are arrayed in the form of a V. They guide the
central bass reflex channel‘s sound energy into the horn‘s port. This
funneling action is smooth and uniform, greatly increasing its range.

The high-quality birch multiplex housing is covered in robust black
textured lacquer and equipped with eight grips.

On the back is a transport dolly that removes easily via quick-release
pins to keep the wheels from rattling.
