STELLA LOUDSPEAKERS

The Stella family of loudspeakers was engineered primarily

®

for use in Meyer Sound’s Constellation

electroacoustic
architecture. The compact, self-powered loudspeakers are
ideally suited for applications requiring exceptional audio
performance, uniform directional control, low-profile mount­ing solutions, and remote power supplies.

Stella loudspeakers include onboard amplification and pro­cessing and exhibit the same high intelligibility, low distor­tion, and flat frequency and phase responses as other Meyer
Sound loudspeakers.

Stella-4C Installation Loudspeaker

The Stella-4 installation loudspeaker is comprised of a 4­inch cone transducer housed in a compact aluminum die
cast enclosure. It delivers an impressive frequency range of
100 Hz to 18 kHz and a maximum peak SPL of 108 dB at
1 meter.

Stella-4 Loudspeaker Mounted with MAMB Adjustable Bracket

The Stella-4 can be easily mounted on ceilings or walls with
mounting accessories available from Meyer Sound and
third-party manufacturers.

CHAPTER 1: INTRODUCTION

Stella-4C Installation Loudspeaker

Stella-4C Ceiling Mount Installation Loudspeaker

The Stella-4C ceiling mount installation loudspeaker offers
the same sonic capabilities as the Stella-4 in a package spe­cifically designed for flushmount ceiling and wall applica­tions, where it can be mounted in standard backboxes for
8-inch drivers (with a minimum depth of 4 inches). The
Stella-4C is housed in an aluminum die cast enclosure with
a rear heat sink.

Stella-8C Installation Loudspeaker

Stella-188 Power Supply

Stella-188 Power Supply

The required method of delivering DC power and balanced
audio to Stella loudspeakers is with the Stella-188 power
supply. The single-space rack unit can power up to 16
Stella-4 or Stella-4C loudspeakers, or up to eight Stella-8C
loudspeakers. The Stella-188 receives eight channels of bal­anced audio from its 25-pin D-sub connector and outputs
the audio, along with 18 V of DC power, to its five-pin Phoe­nix connectors. Each Channel Output can drive up to two
Stella-4/Stella-4C loudspeakers (or one Stella-8C loud­speaker). The Stella-188 front panel has LEDs for monitoring
voltage output and connectivity to the Stella loudspeakers.

Stella loudspeakers receive balanced audio and DC power
from a five-pin Phoenix-style connector on their rear panel.
Meyer Sound's patented Iso-Input™ transformer-isolated
differential inputs yield a high common-mode signal rejec­tion ratio (CMRR). Because Stella loudspeakers have been
optimized to tolerate voltage drops of up to 30 percent, they
can accommodate light-gauge cables and long cable runs.

Stella-8C Ceiling Mount Installation Loudspeaker

The Stella-8C ceiling mount installation loudspeaker delivers
similar acoustical performance as the Stella-4 and Stella-4C
but with expanded output capability and wider coverage.
The unit's 8-inch coaxial cone and 0.75-inch tweeter trans­ducers produce a maximum peak SPL of 117 dB at 1 meter
over a wide frequency range of 100 Hz to 18 kHz. Housed in
an aluminum, die cast enclosure with a rear heat sink, the
Stella-8C can be flush-mounted in ceilings and walls with
standard backboxes for 8-inch drivers (with a minimum
depth of 6.5 inches).
