Extron electronics Four Input Video and RGB Scaler DVS 304 User Manual page 3

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation. The Class A limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses,
and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which
case the user will be required to correct the interference at his own expense.
N
This unit was tested with shielded cables on the peripheral devices. Shielded cables must be used with the unit to ensure compliance with
FCC emissions limits.

the same for both outputs.
Step 5 (for DVS 304 A or
DVS 304 AD only)
Connect up to four balanced or unbalanced stereo
audio input devices to the DVS 304 as shown below.
Each audio input has a 3.5 mm, 5-pole captive
screw connector.
