5.3 Getting to Know Your VM-5AD Amplifier
The KRAMER
VM-5AD is a full spec, state-of-the-art, 1:5 balanced audio distribution amplifier
designed for studio and other demanding applications. The
VM-5AD splits a single input source,
either mono balanced or stereo unbalanced into five identical outputs without any discernible signal
degradation. The
VM-5AD has an audio level control knobs to change balanced or unbalanced audio
signal levels, it can accept microphone input level, balanced mono or unbalanced stereo, amplifying it
to a line level signal. The
VM-5AD allows easy conversion between balanced and unbalanced signals
for maximal flexibility in studios. All circuitry is active with no transformers, thus ensuring hum-
free, full bandwidth operation. The
VM-5AD may be used to convert balanced signal levels and
unbalanced signal levels in both directions, using the level knobs. A microphone signal
(balanced/unbalanced) may be converted to a standard +4dBm balanced level. Front/rear panel
features of the
VM-5AD are described in Figure 3 and Table 3.
