Lectrosonics UCR300 - Manual (Page 5)

UHF Wireless Diversity Receiver
GENERAL TECHNICAL DESCRIPTION
The mute circuit drives a relay which physically disconnects
the output amplifier from the output. This provides complete
muting of the audio and the noise. The pilot tone function may
be bypassed with the Pilot Tone Disable switch (located on the
front panel.) When the pilot tone has been disabled with this
switch, the Pilot LED will glow red and the MOD function of
the LED bargraph meter on the front panel is disabled. The
Pilot LED on the front panel will glow green when the pilot
tone has enabled the receiver audio output.
OUTPUT LEVEL ADJUST AND RANGE SWITCH
The front panel Output control will adjust the audio output
within the range set by the Lo/Mid/Hi range switch (located on
the back panel.) In the Lo position the adjustment range is from
–50dBu to –20dBu, the Mid position (center) allows an adjust­
ment from –30dBu to 0dBu, and the Hi position sets the audio
output to a fixed +8dBu with no front panel control.
POWER SUPPLY
The UCR300 may be operated from an external 10 to 16.5 VDC
source. The power supply has a built in Poly-Fuse to protect the
unit. This fuse resets by simply disconnecting the power supply
for about 15 seconds.
