User manual DLS UP1I INSTALLATION

[. . . ] DLS ULTIMATE TWEETERS Welcome Thank you for buying a DLS Ultimate tweeter. Install the speakers yourself if you feel confident with our instructions and if you have the proper tools. The ULTIMATE speakers are our best speaker line but a poor installation job can destroy the final result even from these speakers. [. . . ] Make sure the cables don't get jammed causing a short circuit to ground. Connect the cables with correct polarity to the speakers.

You can also send an e-mail to info@dls. se Information can also be found on our web-site www. dls. se We follow a policy of continuous advancement in development. For this reason all or part of specifications & designs may be changed without prior notice. Crossover The tweeters must be used with either a passive or an active filter. When the tweeters are a part of a 2- or 3-way speaker system, the filters are included, but if you buy them as separate parts, you must use a separate high pass filter that limits the lower frequency range. If the tweeters are connected without a filter they will be destroyed. A pair of cable filters are normally delivered with the tweeters, but if you don't have the filters you can build your own filter as in the drawing below. If the tweeter level is too high you can connect an extra resistor in series with the + wire. Use a resistor 3, 3 ohms, 5 Watts. Warranty service This speaker is covered by warranty, depending on the conditions in the country where it is sold. If the speaker is returned for service, please include the original dated receipt (or a copy) with the product. P. O.

Attach to the surface with screws (6) or the round adhesive tape cushions (7). [. . . ] The flange (A) is possible to remove from the tweeter driver (B) by turning it CCW. If you prefer to install the tweeter with the flange attached to the tweeter driver, we recommend you to add a string of strong glue on the bottom side, between flange and chamber, to secure it. This gives you the best sound reproduction in this installation. B A [. . . ]
