General Description

Dsppa DSP255 is a weatherproof outdoor column speaker with a 70v/100v transformer built-in.

The 70v/100v transmission is realized in a high-voltage, low-current mode,

which makes longer distance transmission and parallel connection of multiple loudspeakers possible.

The built-in 2 units 3”x5” and 1 unit 2.5” full range speaker drivers are designed of wide frequency response 140-14,000Hz,

the multiple power taps of 8W & 15W could meet different applications varies from room size and ambient noise surroundings

The net cover is made of aluminum and would not rust, it is also designed of weatherproof and heavy damage proof finish;

long-term durability, high sensitivity, clear and sonorous sound.

Easy and secure wall mount installation in outdoor area through the supplied pair of metal mounting brackets.

It is ideal choice for industrial and commercial applications in the outdoor area of train station,

shopping mall, parking area and factory where background music and paging is needed.

Design & Construction Notes

• The IP66 rating ensures the speaker is suitable for outdoor use, resisting dust ingress and powerful water jets (rain, splashing, etc.).

• The aluminum body and grille resist corrosion and weather damage, making it durable in harsh environments.

• Built-in transformer with multiple taps (8 W, 15 W) allows flexibility in system design. In a 70V/100V PA system, you can adjust the power used by each speaker, helping with balanced sound in large installations.

• Use of multiple full-range drivers improves coverage and uniform sound dispersion along the column shape.

• Because it’s a column speaker, it tends to project sound farther and more evenly in the vertical direction, reducing reflections and improving intelligibility in outdoor or semi-outdoor areas.
