INTRODUCTION TO THE 195 SYSTEM
The 195 Series system was designed for the most critical
studio and sound reinforcement applications. The
system design represents a significant step forward in
wireless microphone technology. Every stage in the
entire audio/radio chain from transmitter input to receiver output was evaluated and analyzed to produce the
operating parameters and performance requirements for
this entirely new design. The audio system provides the
lowest distortion and best signal to noise ratio of any
wireless mic system ever built. The RF link is extremely
stable, providing the highest reliability and freedom from
drop outs and interference.
The UCR195 employs the most advanced circuit and
mechanical design ever applied to a wireless microphone
receiver. The audio processing is the finest quality
system ever developed for wireless microphone systems.
The UCR195 re-defines the state of the art in high end
wireless microphone receivers.
The entire radio/audio system was designed from a “cold
start,” utilizing all that has been learned thus far. Many
new types of IC’s and semi-conductors are available now
that were only ideas a few years ago. The UCR195
design takes advantage of these new devices.
UT195 TRANSMITTER
The UT195 hand-held transmitter design was the result
of considerable research. The RF and audio performance
of the transmitter was considered first, followed by an
analysis of the typical user’s needs and the practicality of
various design possibilities. The basic circuitry had to
accommodate any frequency in the VHF or UHF spectrums. The mechanical design had to provide a comfortable “feel,” yet be rugged, foolproof and easy to operate.
The operating features and functions faced several
contradictions in the needs of different types of users.
This led to the development of a very versatile design
wherein the transmitter can be configured for either “fool
proof” operation or to provide user control of the audio
level, metering and indicators. The final UT195 design
combines the benefits of superior performance, ruggedness, user convenience, and flexibility.
UM195 TRANSMITTER
The UM195 is a small belt-pack style transmitter which
can be clipped on the belt, slipped into a pocket, or even
taped to the user's body under clothing. It offers the
same high performance and wide deviation as the UT195
and is compatible with all of Lectrosonics' 195 series
receivers. The UM195 comes with a standard lavalier
microphone but practically any mic can be adapted to
work with this transmitter. The transmitter audio level
can easily be monitored and set from the from panel.
DUAL-BAND COMPANDOR
Compandors have long been a source of audible distortion in wireless microphone systems. The basic problem
is that when the full bandwidth of the audio signal is
processed by a single compandor, the attack and decay
times will always be a compromise. If the time constants are fast, high frequency transient distortion will be
low, but low frequencies will be distorted. If the time
constants are slowed down, low frequency distortion will
be low, but high frequency transients will then be distorted. The
195 system introduces a new approach to solving
this basic problem with compandors, called “dual-band
companding.”
There are actually two separate compandors in the 195
system, one for high frequencies and one for low frequencies. A crossover network ahead of the compandor
separates the frequency bands at 1kHz with a 6dB per
octave slope, followed by separate high and low frequency compandors. The attack and release times in the
high frequency compandor are fast enough to keep high
frequency distortion at an extremely low level. The low
frequency compandor uses slower time constants,
reducing low frequency distortion to well below that of a
conventional compandor.
75kHz DEVIATION
Wideband, 75kHz, of deviation improves the capture
ratio, signal to noise ratio, and AM rejection of a wireless system dramatically.

Compact UHF Receiver
NO PRE-EMPHASIS/DE-EMPHASIS
The signal to noise ratio of the 195 system is high
enough to preclude the need for conventional preemphasis (HF boost) in the transmitter and de-emphasis
(HF roll off) in the receiver. Pre-emphasis and deemphasis in an FM radio system usually provides about
a 10dB improvement in the signal to noise ratio of the
system, but the high frequency boost in the transmitter
must be removed in a purely complementary manner or
else the frequency response of the original audio signal
will be altered.
Pre-emphasis can also cause distortion in the IF filtering
stage in the receiver, since the high frequencies have
been boosted, which increases the level of the harmonics
in the FM signal. As this signal is passed through the IF
filters in the receiver, distortion can be produced, most
noticeable at full modulation. De-emphasis cannot be
applied until the signal is converted into audio, so there
is no way around this problem short of eliminating preemphasis altogether. Neither of these problems occur in
the 195 system. The dual-band compandor in the 195
Series system essentially provides a dynamic preemphasis/de-emphasis function with extremely low
distortion.
EXCEPTIONAL THERMAL STABILITY
If temperature shifts cause the oscillators to drift, or
values to change in the detector, serious distortion will
result. The components in the 195 Series systems meet
very stringent tolerances for thermal drift. System
distortion in the 195 series remains at very low levels
over a very wide temperature range. This is especially
important in applications where the receiver and/or
transmitter must be operated near heat generating
devices, outdoors in direct sunlight, or with the receiver
mounted in an equipment rack.

GENERAL TECHNICAL DESCRIPTION
R
T
UCR195 RECEIVER
The UCR195 is a high performance, dual-conversion,
UHF receiver. The RF performance is extremely stable
over a very wide temperature range, making the UCR195
perfectly suited to the rough environmental conditions
found in the field. The proprietary audio processing
includes a dual-band compandor for very low distortion
and a superior signal to noise ratio. The squelch system
is operated by a separate pilot tone and mutes the audio
output directly at the output connector. The audio output
is calibrated for exact level matching, with a ten LED bar
graph meter.
SIX-POLE HELICAL RESONATOR FRONT-END
The UCR195 utilizes a six-pole helical resonator for
front-end filtering. The helical resonators are custom
manufactured in-house to provide the high performance
needed, yet still fit into the small UCR195 package.
This outstanding front-end keeps the UCR195 from
being affected by high power, adjacent RF signals and
also provides extremely high image rejection.
GaAs FET FRONT-END FILTER COUPLING
The UCR195 utilizes an ultra low noise GaAs FET
amplifier in the front-end section to compensate for the
required losses between filter stages. The GaAs FET
devices are extremely quiet, especially at the higher
frequencies in the UHF band.
DOUBLE BALANCED DIODE MIXERS
A double balanced diode mixer is used in the UCR195 to
produce the 10.7 MHz IF signal. The mixer produces
output at only the sum and difference signals, with
minimal spurious signals. This mixer offers a very high
overload threshold and a high degree of isolation between ports. This translates to the ability of the receiver
to accept higher input signals without overloading and
causing distortion and less cross talk between receivers
in multiple system installations.
10 POLE LINEAR PHASE FILTER
The 1st IF amplifier is a 4 stage amp with 2 poles of
filtering after each stage. The filters are high quality,
low distortion, constant group delay ceramic filters. This
special type of filter is needed to accommodate the wide
deviation of the 195 system. The 2nd IF incorporates 2
more poles of filtering.
DIGITAL PULSE COUNTING DETECTOR
The UCR195 receiver uses an advanced digital pulse
counting detector to demodulate the FM signal, rather
than a conventional quadrature detector. The most
common problem with quadrature detectors is thermal
drift, particularly those that operate at higher frequencies
like 10.7 MHz. The UCR195 design presents an elegantly simple, yet highly effective solution to this age
old problem.

Compact UHF Receiver
The UCR195 detector basically works like this: A
stream of DC pulses is generated at 455kHz. The pulse
width is constant, but the timing between pulses varies
with the frequency shift of the FM signal. The pulse
stream is controlled by the FM signal coming from the
IF section which has been heavily limited. The average
voltage of the pulses within any given time interval
varies in direct proportion to the frequency modulation
of the radio signal, producing the audio signal.
This type of detector eliminates the traditional problems
with quadrature detectors and provides very low audio
distortion and no thermal drift. The counting detector
also adds additional AM rejection, in addition to the
limiting in the IF section. The amplitude of the pulses is
constant, so level differences in the IF signal do not
affect the pulse.
2:1 EXPANDER (Dual–Band Compandor)
This circuit is the other half of the dual-band compandor
in a 195 system. “Dual-band Companding” is a closed
loop system, that is, whatever is done in the transmitter
must be mirrored in the receiver. The transmitter compresses the audio signal in two separate audio bands
using two separate time constants in order to avoid the
inevitable trade-offs in a single-band compandor. The
companion circuit in the receiver then re-expands this
compressed signal restoring the original dynamic range
and frequency characteristics of the signal.
The audio signal leaves the Detector circuit and is fed
through an amplifier to the 23 kHz Low Pass Filter
where all the high frequency noise (including the 32 kHz
pilot tone) is filtered out. After the 23 kHz low pass
filter, the signal is split into two parts via a 1 kHz low
pass filter and a 1 kHz high pass filter. The separated
signals are then processed in separate channels of the
NE572 2:1 Expander. Each channel of the 2:1 Expander
is optimized for its respective frequency band. The two
outputs of the 2:1 Expander are then summed in an opamp summer and sent to the output amplifier as one
signal.
PILOT TONE MUTE (SQUELCH)
The 195 system utilizes a separate ultrasonic tone
modulation of the basic carrier to operate the receiver
squelch. In the transmitter, a 32kHz tone is injected into
the audio signal path just after the compandor. The
supersonic pilot tone is filtered out of the audio signal
immediately after the detector in the receiver so that it
does not influence the compandor or various gain stages.
The basic benefit of the pilot tone squelch system is that
the receiver will remain squelched (muted) until it
receives the pilot tone from the matching transmitter,
even if a strong RF signal is present on the carrier
frequency of the system. Once a pilot tone is received,
the receiver will remain open during all signal conditions.
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 in the battery compartment.)
When the pilot tone has been disabled with this switch,
the MOD function of the LED bargraph meter on the
front panel is also disabled. The Pilot LED on the front
panel will glow 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 Low/High/Fixed range
switch (located inside the battery compartment.) In the
Low position (toward the front panel) the adjustment
range is from –50dBm to –20dBm, the High position
(center) allows an adjustment from –30dBm to 0dBm,
and the Fixed position (toward the rear panel) sets the
audio output to a fixed +8dBm with no front panel
control.
POWER SUPPLY
The UCR195 may be operated from internal 9 Volt
batteries, from the supplied CH12 adapter, or from an
external 12 to 18 VDC source. The power supply has
protection circuits which prevent damage to the receiver
if a positive ground voltage source is used. The power
supply also has a built in Poly-Fuse to protect the unit.
This fuse is self healing by simply turning off the
receiver for about 15 seconds.

FRONT PANEL CONTROLS AND FUNCTIONS
PWR LED
When lit, this LED indicates that power is applied to the
UCR195 and adequate voltage is present to operate the
unit.
PILOT LED
The audio output muting (squelch) function of the
UCR195 is controlled by a 32kHz tone modulation of
the RF carrier. The audio output is muted until this tone
is present. This LED will remain on as long as the
receiver audio is enabled by the pilot tone.
TRANSMITTER AUDIO LEVEL METER
When the meter function switch is in the Mod position,
the modulation (audio level) of the incoming signal is
indicated by a fast responding LED strip. The strip is
calibrated in 6dB steps over an expanded scale (54dB)
which provides an extremely accurate visual “picture” of
the signal dynamics, even at a distance away from the
receiver. Audio signal peaks easily exceed the response
time of VU meters, however, the LED strip is fast
enough to track even brief transients.
RF LEVEL INDICATORS
With the function switch in the RF position, the LED
strip indicates the level of the incoming RF signals. The
LED strips are calibrated to provide accurate indications
from 1uV to 1mV. The LEDs are highly visible from a
distance, making antenna set up more accurate. The
LED strip is especially useful in “troubleshooting”
difficult antenna installations.
MONITOR
This is a high quality audio output to drive a wide
variety of different types of headphones. It is also
useable as a secondary audio output to feed recorders or
external audio devices. The Monitor jack is a mini
stereo type with the same signal applied to the tip and
ring contacts. Stereo or mono headphones may be used
without any loss of volume or damaging the UCR195.
POWER SWITCH
This slide switch, and its corrosponding LED indicator,
switches the receiver from Off to internal or external
power. At turn on and off there is a delay built into the
receiver to allow various stages to stabilize before the
audio output is activated. This will prevent an audio
“thump” when powering up the receiver.
AUDIO OUTPUT
The front panel Audio Output control will adjust the
audio output within the range set by the Low/High/Fixed
range switch (located inside the battery compartment.)
In the Low position (toward the front panel) the adjustment range is from –50dBm to –20dBm, the High
position (center) allows an adjustment from –30dBm to
0dBm, and the Fixed position (toward the rear panel)
sets the audio output to a fixed +8dBm with no front
panel control.

REAR PANEL CONTROLS AND FUNCTIONS
EXTERNAL POWER JACK
The UCR195 can be powered from external 12 to 18
Volts DC applied directly to this jack, or conventional
110 VAC sources via the supplied CH12 adapter. The
UCR195 is protected from reverse polarity conditions
which prevents damage if a positive ground power source
is applied. The center pin of this jack is POSITIVE.
AUDIO OUTPUT XLR JACK
This jack is a standard 3 pin XLR connector since this is
the most commonly used type of connector. Audio High
is on pin 3, audio Low is on pin 2, and audio Common is
pin 1. The XLR body also provides a sturdy pivot for
the battery door mechanism.
RANGE SWITCH
The audio output range switch is located inside the
battery compartment and is the switch nearest the front
panel. There are three positions: Low (toward the front
panel), High (center position), and Fixed +8dBm (toward
the rear panel.) This switch controls the range of adjust-
Compact UHF Receiver
ment of the front panel Audio Output control. In the
Low position the adjustment range is from –50dBm to –
20dBm, the High position allows an adjustment from –
30dBm to 0dBm, and the Fixed position sets the audio
output to a fixed +8dBm with no front panel control.
PILOT TONE DISABLE
Inside the battery compartment the switch nearest to the
rear panel is the Pilot Tone Disable. This is a two
position switch. The position toward the front panel is
the normal operating position and allows the pilot tone to
enable or disable the receiver audio output. The other
position, toward the rear panel, will disable the pilot tone
action and will cause the receiver audio output to always
be enabled, even in the absence of a transmitter signal.
This position is only used for troubleshooting and should
never be set during actual use. When the pilot tone is
disabled with this switch, the Mod meter on the front
panel is also disabled.

ANTENNA USE AND PLACEMENT
Position the antenna so that it is more than 3 or 4 feet
from large metal surfaces. If this is not possible, try to
position the antenna so that it is as far away from the
metal surface as is practical. You can also let the metal
surface work for you by aligning the antenna perpendicular to the surface. This will provide a ground plane for
the antenna. It is also good to position the receiver and/
or antenna so that there is a direct “line of sight” between the transmitter and the receiver antenna. In
situations where the operating range is less than about 50
feet, the antenna positioning is much less critical.
A wireless transmitter sends a radio signal out in all
directions. This signal will often bounce off nearby
walls, ceilings, etc. and a strong reflection can arrive at
the receiver antenna along with the direct signal. If the
direct and reflected signals are out of phase with each
other a cancellation may occur. The result would be a
“drop-out.” A drop-out sounds like either audible noise
(hiss), or in severe cases, may result in a complete loss
of the carrier and the sound when the transmitter is
positioned in certain locations in the room. Moving the
transmitter even a few inches will change the sound of
the hum or hiss, or eliminate it. A drop-out situation
may be either better or worse as a crowd fills and/or
leaves the room, or when the transmitter or receiver is
operated in a different location.
The UCR195 receiver offers a sophisticated front end
design which overcomes drop-out problems in almost
any imaginable situation. At UHF frequencies, drop outs
(noise ups) are often so brief that they sound like a
"click" rather than a burst of noise. Generally, drop outs
are virtually non-existent within several hundred feet of
operating range. In the event, however, that you do
encounter a dropout problem, first try moving the
antenna at least 2 or 3 feet from where it was. This may
alleviate the drop-out problem. If drop-outs are still a
problem, try moving the antenna to an entirely different
location in the room or move the antenna in closer to the
transmitter location.
Lectrosonics transmitters radiate power very efficiently,
and the receivers are very sensitive. This reduces dropouts to an insignificant level. If, however, you do
encounter drop-outs frequently, call the factory or
consult your dealer. There is probably a simple solution.

OPERATING INSTRUCTIONS
1. Connect the power cord or install the batteries.
2. Attach the antenna.
3. Connect the audio cable to the audio output XLR.
4. Set the front panel Audio Output Level control to minimum and set the Power switch to either Int or Ext, depend-
ing upon the power source. Check to see that the front panel Power LED lights up.
5. Adjust the transmitter gain. THIS IS PERHAPS THE MOST IMPORTANT STEP IN THE SET UP PROCE-
DURE. See your transmitter manual (Operating Instructions section) for details on how to adjust the transmitter
gain. In general, adjust the transmitter gain so that the voice peaks will cause the 0dB LED on the front of the
receiver to light on the loudest peak audio levels. This will result in the best possible signal to noise ratio for the
system without causing overload distortion.
6. Adjust the Audio Output control according to the type of input on your equipment. The Range switch (located in
the battery compartment) sets the adjustment range of the front panel Audio Output control and has three positions.
Low (toward the front panel): The adjustment range is from –50dBm to –20dBm.
High (center): Allows an adjustment from –30dBm to 0dBm
Fixed (toward the rear panel): Sets the audio output to a fixed +4dBm with no
front panel control.
The input levels of different cameras, VCRs, and PA equipment vary, which may require that you set the Audio
Output control to an intermediate position. Try different settings and listen to the results. If the output of the
receiver is too high, you may hear distortion or a loss of the natural dynamics of the audio signal. If the output is
too low, you may hear steady noise (hiss) along with the audio. The UCR195 audio output is designed to drive
any audio input device from microphone level to +8dBm line level.
Note:
When using the +4 dBm FIXED position of the output range switch, do not ground pin 2 or pin 3 of the XLR
output! The output impedance is only 50 Ohms (unbalanced) when in the FIXED position and this is not enough to
isolate the audio amplifier from a short to ground. Distortion will result. This is in contrast to the DR195 receiver
which has a transformer coupled output. With a transformer coupled output, one end needs to be grounded when
connecting an unbalanced load to the output jack.

TROUBLESHOOTING
POWER SUPPLY AND FUSE
LEDs not lit or dimly lit
• AC power cord disconnected.
• External power supply disconnected or
inadequate.
• Main power supply fuse tripped. Turn the
receiver off, remove the cause of the overload
and turn the receiver back on.
• Wrong polarity power source. The external DC
in requires POSITIVE to be on the center pin.
PILOT TONE SQUELCH
The PILOT indicator lamp on the front panel lights up to
indicate that the audio has been turned on at the
transmitter, and that the audio output on the receiver is
enabled. When the lamp is on, the audio is enabled.
When the lamp is off, the audio is muted.
PILOT lamp on, but no sound
• Audio output cable bad or disconnected. Try
monitoring at the headphone output on the front
panel. The headphone output signal is taken just
ahead of the output transformer.
• Audio Output level set too low.
PILOT lamp off, but sound still comes through
• Pilot Tone Bypass switch may be on. Open the
battery compartment, remove the batteries, and
check the switch nearest to the rear panel. This
switch should be in the position toward the front
panel.
PILOT lamp does not come on when transmitter
audio switch is turned on
• It takes several seconds for the relay to actuate
the PILOT lamp. Turn the transmitter power and
audio switches on and wait 5 to 10 seconds for
the lamp to come on.
Normal audio on output but the Mod meter on
the front panel is not working.
• The Pilot Tone Disable switch may be on.
Open the battery compartment, remove the
batteries, and check the switch nearest to the rear
panel. This switch should be in the position
toward the front panel.
ANTENNAS AND RF SIGNAL STRENGTH
RF Level is weak.
• Antenna is disconnected or there is a bad
connection
• Antenna may need to be moved or re-oriented
• Improper length of antenna, or wrong antenna.
UHF whip antennas are generally about 5 to 6
inches long. UHF helical antennas may be
shorter, but are often less efficient.
AUDIO SIGNAL QUALITY
Poor signal to noise ratio
• Transmitter gain set too low
• Noise may not be in wireless system. Mute the
audio signal at the transmitter and see if noise
remains. If the noise remains, then turn the
power off at the transmitter and see if it remains.
If the noise is still present, then the problem is
not in the transmitter.
• If noise is still present when the transmitter is
turned off, try lowering the audio output level on
the UCR195 rear panel and see if the noise
lowers correspondingly. If the noise remains, the
problem is not in the receiver.
• Receiver output is too low for the input of the
device it is feeding. Try increasing the output
level of the UCR195 and lowering the input gain
on the device the UCR195 is feeding.
Distortion
• Transmitter input gain too high. Check and/or
re-adjust input gain on transmitter according to
the LEDs on the transmitter and then verify
the setting with the transmitter audio level LED
strip on the UCR195 front panel.
• Audio output level too high for the device the
UCR195 is feeding. Lower the output level of
the UCR195.
