CARD FRAME P
ACKAGES
The INTEGRA III SYSTEM Card Frame Packages
are designed to provide fast, easy installation of all
modules in the system.
The card frame package Model 858B will accomodate
9 plug-in audio modules and the plug-in power supply
module. The unit incorporates a UL recognized power
supply. It is recommended for smaller systems, or
systems having modules mounted in multiple loca-
tions or racks. Due to the power supply current rating,
systems using multiple power amplifier cards should
use the companion Model 857B card frame package.
The 858B backplane buses power supply voltages,
and ground to all card slots, and provides capture
type Euro-Style connection terminals for all wiring.
This feature greatly reduces the time required to wire
the card frame assembly.
The Model 857B card frame package will allow mount-
ing of up to 10 audio modules, and is designed for use
with the external power supply Model 66708. The
external power supply has sufficient current rating to
allow multiple power amplifiers to be mounted
within a single card frame, and/or to power multiple
card frames in larger systems. Busing, and
connections are similar to the Model 858B package.
In order to accomodate the wide variety of grounding
schemes encountered in large audio systems, both
card frame packages incorporate a ground-lift
switch. The switch allows the INTEGRA III SYSTEM
to interface with any other equipment grounding re-
quirement.
