The Protech Audio Switchable Input Mixer cards
are designed for use by audio professionals.
Each unit is carefully designed and constructed
to provide highly reliable, quiet switching of
audio signals to an on-board output, and a link
output. The unit may be used to control paging
systems, provide signal routing in broadcast
facilities, or sound system configuration in live
venues.
All 3 models are configured as a two input
mixer cards. Different input combinations (mic
or line) are available as follows;
Model 702LL = 2 Line Inputs.
Model 702ML = 1 Mic Input, 1 Line Input.
Model 702MM = 2 Mic Inputs.
The Model 702 cards are linkable, allowing larger
systems to be configured. By applying ground
to the individual channel control pins, each input
channel may be assigned to the on-board
output, or the link out. The on-board output is
balanced, transformer-isolated. The output is
designed to drive 600-15K ohm loads. The link output for each input channel has a
separate switch from the on-board output switch.
This feature allows the input channel signal to
be assigned to the link output, or the on-board
output, separately.
The gain of each input channel is adjustable,
via on-board, or backplane mounted trimpots. For
backplane mounted trimpots, simply add the suffix
"BP" to the part number (see back page of this
sheet for additional part number information).
As one of the INTEGRA III SYSTEM modules, the
Model 702 Mixer cards may be mounted in any
of the system enclosures manufactured by
Protech Audio. The Model 858B Card Frame
Package will allow up to 9 plug-in cards plus a
plug-in power supply, in just 3.5" of vertical rack
space. The Model 857B allows mounting of up to
10 cards in 3.5" of rack space, and requires an
external power supply (Model 66708).
