The Redbox Range of Products
Redbox are a range of audio and video interfaces designed for use in critical
broadcast applications where the product needs to be powered 24 hours a day, 365
days a year. Manufactured to the highest standards in our UK offices, utilisation of
the finest components and critical quality control techniques ensure that your
Redboxes work every time, for years to come. They are "fit and forget" products - you
can set them up, fit them in your installation and then forget about them.
Features
•
All are equipped with IEC mains lead and instruction manual.
•
In-house design and manufacture ensures high quality control standards.
•
All units are 115V 60Hz or 230V 50Hz switchable, or universal and all have a
front panel LED power indicator.
