RAM-50 Room Amplifier Modules
are used as needed, one RAM-50 for each
room/zone. The amplifier provides 50 Watts per channel and is stable
down to 4
Ω
. Each RAM-50 also provides: a fixed line-level output for use
with surround decoders (SSD-66 or SSD-66THX Decoders); a variable line-
level output for use with external power amplifiers for greater power (PF-
250, 250W/Ch Amp) or when driving an impedance load below 4
Ω
(PF-200,
1/2
Ω
stable power amp); and banana pin speaker jacks. For rooms which
may need more amplification than a single RAM-50 can provide, several
RAM-50s can be slaved off of a main RAM-50 while tracking the same source
and acoustical settings. While a single Delta-88 can hold up to eight RAM-
50s, you can assemble the Delta-88 with exactly the right number of RAM-
50s to suite your particular project. Any unused slots in the Delta-88 are
available for future zones.
RBM-50 Room Bass Amplifier Modules
are used for rooms that have a passive
subwoofer. The RBM-50 can be pre-ordered to a specific frequency roll-off
point and provides 100 Watts of subwoofer power stable down to 4
Ω
. When
using a RBM-50, the signal to the bass amplifier is derived from a RAM-50's
variable line level output. Even though the RBM-50's bass level is set in
software, once set, the bass level will track the RAM-50's volume
(room's volume level). The RBM-50 will take the space of one RAM-50
in the Delta-88. Thus, using one RBM-50 in a single Delta-88, will leave
space in the Delta-88 for up to seven RAM-50 Room Amp Cards.
VSM-8 Video Switching Modules
are available for providing com-
posite video-follow-audio switching within the Delta-88. A single
VSM-8 takes a card slot inside the Delta-88. Thus, using one VSM-8
(only one per Delta-88) in a single Delta-88, will leave space in the Delta-88 for up
to seven RAM-50 Room Amp Cards. A single VSM-8 can provide switching of up
to eight video sources to up to seven zones. When using several Delta-88s to make
up a system where each zone requires composite video switching, each Delta-88
will require one VSM-8.
