The 2807 is a compact instrument
of modular construction providing
stabilized voltages for 8 & K
Microphone Preamplifiers and
Condenser Microphones. The low
output impedance of its two amplifier
channels enables long cables to be
used for connection of indicating
instruments. The two channels may
be monitored simultaneously, or they
may be automatically or remotely
switched so they can be monitored
alternately using a single
indicating instrument.
