LR-100 Speaker Connection
LR-100 Antenna Installation
The LR-100 contains a 44-watt (31 watt RMS), 4 ohm power amplifier.
The Speaker Selection switch determines what audio is directed to the power amplifier. With the switch in the
OUTPUT position, the OUTPUT audio (same audio that is on the OUTPUT audio connectors) is directed to the power
amplifier. With the switch in the AUX position, only AUXILIARY input audio is directed to the power amp. This allows
you to use the power amp separate of the RECEIVER audio if desired.
NOTE: When the speaker switch is in the OUTPUT position and the MUTE control is enabled (indicated by the
illumination of MUTE LED), the speaker output is also muted.
Connection to the speaker is achieved through pins 1 and 2 on the detachable terminal block. Strip the speaker
wires, rotate the screws on the terminal block counter-clockwise, insert the wires and then tighten the screw
clockwise until the wire is secure in the connector block. You may connect any parallel, series combination of
speakers that produces an impedance of 4 ohms or greater.
EXAMPLE: If you have two 8 ohm speakers, you can connect these in parallel to produce a 4 ohm load to the
power amp.
The SPEAKER level control on the front panel adjusts the level of the speaker.
The front panel headphone jack is in parallel with the speaker level. Connect any mono or stereo headphone to
this 3.5 mm jack. Adjust level with the SPEAKER volume knob.
Installation of Antenna
A properly installed antenna is critical to the operation of the LR-100. Without a strong and consistent RF signal from
the transmitter, the LR-100 will not meet the needs of your installation. You can use the RF POWER indication on the
LCD to provide a relative RF signal strength. You should see four or more dots displayed on the LCD for best results.
Using the supplied helical antenna
Connect the antenna to the rear BNC connector and orient the antenna vertically. If reception is from the
transmitter is not adequate, consider using a remote antenna (see below) or place the LR-100 at an improved
location to improve the signal strength. See RF Reception Maximization Strategies on page 17 for more information.
Using a remote antenna
For better reception in longer broadcast range applications, you should use a remote antenna. A remote antenna
will allow you to get the antenna higher in altitude and in a position that is clear of obstructions. Please refer to the
specific antennas instructions for installation. Also refer to Strategies for Maximizing RF Reception on page 17 for
additional information.
CAUTION: When installing antennas, ensure the antenna is clear of power lines.
NOTES: If the RF signal to the 216 MHz model is too high, the audio will be distorted. This may happen if the LR-100
is within 40 feet of the LT-800-216 transmitter. Consider reducing the output power of the transmitter or
optionally removing the antenna on the LR-100 (there is sufficient internal antenna inside the LR-100 to
receive an adequate signal from the transmitter).
