5.1 Getting To Know Your VM-80V
The Kramer VM-80V is a broadcast quality distribution amplifier designed primarily for composite video
signals on BNC connectors. Using a simple rear panel switch, it can be configured either as a single 1:8 DA, or
as two separate 1:4s. In either mode its purpose is to provide identical outputs to drive multiple monitors,
projectors or other receiving devices. Bandwidth exceeding 330MHz ensures transparent performance, even
with high-resolution analog and SDI (serial digital) video signals. The inputs can be un-terminated to provide
looping capability, making it easy to create larger systems. The VM-80A is the companion unit for distributing
balanced audio signals. Two sets of recessed front panel controls are provided for fine-tuning of gain and high
frequency EQ. The VM-80V is housed in a rugged, professional half-rack enclosure with an internal power
supply connected by a standard, detachable AC power cord. Two “80” series products can be mounted in one
vertical rack space using the RK-80 kit. Front/Rear panel features of the VM-80V are described in Figure  and
Table 1 .
