SOLID-STATE SWITCHING CARD
INSTALLATION & OPERATION MANUAL
®
The 590B Programmable solid-state switching card is
designed for use in professional audio applications. The
card is constructed to function as a solid-state switch.
There are five pairs of Form A contacts on each switch
card. The switch contacts are activated by a remote
closure to ground.
Typical applications are public address systems,
broadcast studios, sales presentation rooms, headphone
listening systems, multi-room audio systems, and record-
ing systems. The actual application of the amplifiers is
found in buildings such as airports,
factories, courthouses, casinos, convention centers,
libraries, hotels, racetracks, training systems, corporate
boardrooms, etc.,.
The 590B has four logic programs built-in to each card.
The programs are selectable via an on-board dip switch.
The first program is designated "Independent". This pro-
gram allows each set of contacts to operate independently
of each other.
The second program is designated "Lockout". This pro-
gram operates on the first-come, first-served principle,
with all other closures locked out until the active channel is
released. This program is very useful in paging applica-
tions. The third program is designated "Last-On". This program
allows the active channel to be turned off whenever a new
channel closure is selected. This program is extremely
useful in legislative venues, where the chairman wishes
to assign access to the public address system.
The fourth program is designated "All-On". When the card
is set for this program any ground closure will activate all
five sets of closures. This program is useful in controlling
multiple outputs from devices such as audio distribution
amplifiers.
The Model 590B card is linkable. Multiple cards may be
linked together to create 10, 15, 20, etc. channel electronic
switches. Four cards linked together, with switches set for
the "Lockout" program, create a 20 station electronic
switch with first-come, first-served capability.
Multiple cards, set to different programs may be used
together to accomodate various systems requirements. Other
INTEGRA III SYSTEM switching cards may be used in
conjunction with the Model 590B to provide additional
switching functions.
Each of these products is designed to provide the user with
high quality audio, for years of uninterrupted service.
