2.1 MECHANICAL INSTALLATION
The Model SAP1626 mounts in a standard 19 inch
rack, in a space two rack units high (3.5 inches). The
BOP220 should be mounted in the same rack as the
SAP1626 behind the SAP1626.

The SAP1626 distributes DC power and signals but
is
no power
and there are no power connections.
2.2.2 ELECTRICAL INSTALLATION, SIGNALS
The electrical installation of the SAP1626 requires
one to four four-conductor shielded cables, two f@-
conductor cables, and optionally, a twenty five-con-
ductor cable, and microphone cables.
The one to four four-conductor cables
connect one to four TW* Power Supplies, respec-
tively, to the SAP1626 "INTERCOM

Figure 2-6 shows the interconnection of the SAP1626

Since the SAP1626 has no current limiters, PS50 and
PS60 power supplies may shorten the life of the
thumbwheel switches, but current limiters may be
added to the SAP1626. See Appendix B for a triple
current limiter, circuit assembly. To protect all 12 ac-
tive buses of the SAP1626 requires 4 assemblies.

provides two channels of two-wire intercom per

4.1 OVERALL FUNCTIONAL DESCRIPTION
(See Figure 4-1)
GENERAL The SAP1626 Source Assignment Panel
is a rack-mounted matrix switch. This switch assigns
each of 20
possible buses. Twelve buses
power and intercom signals. Three buses distribute
intercom signals or program signals. The matrix
switch has the effect of transforming a basic two bus
intercom system to a fifteen bus system. The switch
also assigns six camera intercom stations to a pair of
intercom/program buses or twelve camera stations to
a single intercom/program bus.
SAP1626 BUSES There are three kids of buses in
the SAP162.6: 1) two-way two-wire type intercom
buses,
buses, and 3) program audio buses. There are twelve
primary intercom buses and three program or sec-
ondary intercom buses. All buses allow for two-way
two-wire intercom operation. The twelve primary
buses may also be "powered" buses. The powering
accomplished by plugging
into the SAP1626. The powering allows a
com station to receive power on its channel one wire
(one
the SAP1626). Most

Up to ten user stations may be in a group of
stations connected to a SAP1626 output. The twenty
outputs discussed above are available on the back of
the SAP1626 on two fifty-conductor connectors, or on
the optional BOP220 as twenty three-conductor male
XLR type connectors.
