Stella-4C Installation Loudspeaker

The Stella-4C ceiling mount installation loudspeaker offers 
the same sonic capabilities as the Stella-4 in a package spe-
cifically designed for flushmount ceiling and wall applica-
tions, 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

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 trans-
ducers 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).

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 bal-
anced audio from its 25-pin D-sub connector and outputs 
the audio, along with 18 V of DC power, to its five-pin Phoe-
nix connectors. Each Channel Output can drive up to two 
Stella-4/Stella-4C loudspeakers (or one Stella-8C loud-
speaker). 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 rejec-
tion 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.
