INTRODUCING THE STELLA-4
The Stella-4 is a self-powered loudspeaker designed prima-
rily for installations with the LCS Constellation system. Its
single 4-inch cone transducer, housed in a compact alumi-
num die cast enclosure, delivers an impressive frequency
range of 100 Hz to 22 kHz and a maximum peak SPL of
108 dB (93 dB average) at one meter. Containing onboard
amplification and processing, the Stella-4 exhibits the same
high intelligibility and flat frequency and phase response
characteristic of Meyer Sound loudspeakers.
The Stella-4 receives balanced audio and DC power from a
five-pin Phoenix-style connector on its back panel. Meyer
Sound's patented Iso-Input™ transformer-isolated differen-
tial inputs yield a high common-mode signal rejection ratio
(CMRR). Because the Stella-4 has been optimized to toler-
ate voltage drops of up to 30% it can accommodate light-
gauge cables and long cable runs.
The required method for delivering DC power and balanced
audio to the Stella-4 is with the Stella-188 Power Supply.
The single-space rack unit can accommodate up to 16
Stella-4s. The Stella-188 accepts balanced audio through its
25-pin D-sub Audio Input connector and outputs the audio,
along with 18 V of DC power, to its five-pin Phoenix Channel
Output connectors. The front panel of the Stella-188 has
LEDs for monitoring voltage output and connectivity to the
Stella-4s.
