Niles Audio DS8.3, DS8..5 manual Introduction

Introduction

Niles DS Directed Soundfield loudspeak- ers feature a fully patented, adjustable, independently pivoting, woofer and tweeter that enables the loudspeakers to accurately recreate high fidelity sound

regardless of where they are located in the ceiling — preserving interior design integrity and delivering life-like sonic quality that is not available from conven- tional ceiling loudspeakers.

Features and Benefits

Features and Benefits

Fully pivoting woofer and tweeter

A pivoting woofer assembly can adjust up to 15° focusing bass and midrange tones directly at the listening area for superb imaging and unparalleled clarity. Within the woofer assembly, the tweeter is housed in its own low-diffraction pivoting assembly that can adjust up to 17° in any direction to create direct or diffused sound fields. The independently pivoting woofer’s and tweet- er’s superior design is patented, (U.S. patent number 6,683,963).

12 AWG Push Terminal

The DS8.3 and DS8.5 loudspeakers are manufactured with high quality gold plated push terminals that insure that the connection to the speaker cable is of the highest quality available.

Moisture and UV Resistant

Construction

The DS8.3 and DS8.5 loudspeakers are suitable for use in high moisture environ- ments. The drivers are resistant to moisture and UV exposure; the grille is made of powder-coated aluminum. However, the speakers are not waterproof and direct contact with water should be avoided.

Engineered for Ceiling Placement

The increased popularity of cathedral and vaulted ceilings pose a distinct sonic challenge for conventional ceiling loud- speakers. That is because conventional ceilingloudspeakers radiate sound perpen- dicular to their mounting surface, which

usually is not where the listening area is. DS Directed Soundfield Loudspeakers patented, independent pivoting woofer and tweeter overcome this challenge and allow sound to be directed into the listen- ing area regardless of ceiling angle.

Installer Selectable Acoustic

Fine Tuning

Installers can select to fine tune the bass or treble to accommodate reflective surfaces and corner loading. This selection is accomplished via the baffle-mounted treble control (-1.5dB, flat and +1.5dB) and PC board mounted bass jumper (flat, -1dB, and -2dB).

4 or 8 ohm Selectable Impedance

The DS8.3 and DS8.5 give the installer flexibility to select the speaker’s imped- ance — 4 ohms for systems where maximum current transfer and output level is desired; 8 ohms for systems utilizing multiple speaker pairs where amplifier loading is a consideration.

MicroPerf™ Grilles

The DS8.3 and DS8.5 employ Niles exclusive MicroPerf grille construction. The exceptionally tight hole pattern provides acoustic transparency at all audio frequencies and enables the speaker elements to remain invisible. MicroPerf grilles can also be painted to blend seemlessly with the surrounding decor.
