Lectrosonics UCR310 - Manual (Page 5)

UHF Wireless Diversity Receiver
spond too rapidly and the audio sounds “choppy”, respond too
sluggishly and syllables or entire words are cut off.
The UCR310 combines several techniques to achieve an optimal
balance, removing distracting noise, without the squelching action
itself becoming a distraction. One of these techniques involves
waiting for a word or syllable to complete before squelching.
Another incorporates recent squelching history and recent signal
strength, adjusting squelching behavior dynamically for the most
serviceable result under variable conditions. Using these and other
techniques, the UCR310 can deliver acceptable audio quality from
otherwise unusable signals.
In the “PILOT TONE BYPASS” mode, the squelch system is
disabled. Received audio remains unmuted at all times with this
setting.
OUTPUT LEVEL ADJUST AND RANGE SWITCH
The front panel Output control will adjust the audio output within
the range set by the -20/0/+8 range switch (located on the back
panel.) In the -20 position the adjustment range is from –50dBm to
–20dBm, the 0 position (center) allows an adjustment from –
30dBm to 0dBm, and the +8 position sets the audio output to a
fixed +8dBm with no front panel control.
POWER SUPPLY
The UCR310 may be operated from an external DC source (see
Specifications and Features section for allowed voltages.) The
power supply has a built in Poly-Fuse to protect the unit. This fuse
resets if the power supply is disconnected for about 15 seconds.
