IEC-708
8-Input Vertical Interval Video Switcher
A wide bandwidth vertical
interval switcher, with 8 BNC
terminating inputs and dual
outputs allowing users to
efficiently and economically
route or delegate multiple
video signals. The stand-alone
IEC-708 features eight lighted
momentary push-button switches for video selection. Switching is
accomplished during the vertical interval by the vertical sync derived
from the video at the output stage of the IEC-708 video switcher.

IEC-715 Video Presence Detector
Designed to monitor its
primary video input signal
and automatically switch to
an auxiliary video input with
the loss of the primary video
signal. A captive screw
terminal sub-module is
provided for “audio-follow-video capability for mono or stereo audio
switching. A 3-terminal screw block provides dry contacts for normally
open (N.O.) and normally closed (N.C.) to control peripheral gear.
Incorporates a unique noise immunity circuit that prevents the video
detector from being fooled by high level noise on its input. A relay
provides a hard by-pass of the primary video signal in the event AC
power is lost to the unit. Front panel “By-Pass” and “AUX Select”
switches allow you to override the automatic change-over function
and choose either video source. A front panel “Status” LED indicates
the condition of the primary video input.

NTSC/PAL Master
Blackburst Generator
with Audio Tone
Ideal for studio, remote
locations, or production
facilities where an economical
yet accurate multiple blackburst source is needed, the IEC-712 provides
six precision blackburst outputs for system distribution. An AC line
voltage switch is also provided to select the proper AC line supply.
Comes standard with a 5ppm crystal oscillator. Two optional crystals
are available for 1ppm and 0.5ppm operation.
In addition, a high quality dual sine wave tone generator is provided for
audio system testing. The balanced, low impedance output conforms
to AES standards for audio distribution. A front panel switch selects
between 400 Hz or 1KHz. Additional controls on the front panel provide
modulated ramp on and off, and black set-up on and off.

IEC-720
Blackburst and Color Bar Generator
Provides two precision black-
burst outputs for system timing
and two color bar or flat field
outputs. Factory adjusted to
RS-170A standards, the IEC-720
is perfect for the studio, remote
locations, or production facilities
where an economical and accurate blackburst source generator is
needed. In addition, a high quality digitally produced 1KHz tone
generator is provided for audio system testing. A rear panel terminal
block allows for easy connection to the system.

IEC-740 1:8 Mono or 2:4 Stereo Audio DA
Extremely versatile, the IEC-740
can be configured for balanced
or unbalanced operation,
mono or stereo. The input is
high impedance bridging. All
inputs and outputs use multi level
screw clamp terminals. A front
panel switch allows operation as a mono 1x8 DA or 2x4 mode for stereo
operation. A gain trim control for each channel allows for independent
level matching to approximately 16dB. The IEC-740 is a self-contained
audio DA with an on-board power supply that draws only 4 watts. A
fuse accessible from the front panel provides easy replacement.

1x8 or Dual 1x4 Video DA
The IEC-750 is a versatile 1x8
composite video DA with the
ability to operate as a dual
1x4 amplifier with the push of
a button. In 1x8 mode input is
high impedance loop through,
in the dual 1x4 mode, the input
is terminated internally. The dual mode of operation provides four
outputs of each of the two inputs. Two gain controls on the front panel
adjust the video level to ±3dB for each set of four outputs. A switch on
the rear panel allows for differential or single-ended inputs. On-board
power supply draws only 4 watts.
