Example: If you have two 8-ohm speakers, you can connect these in parallel to pro- duce a 4-ohm load to the power amp.

iii.The SPEAKER level control on the front panel adjusts the level of the speaker.

iv.The front panel headphone jack is in parallel with the speaker level. Connect any mono or stereo headphone to this 3.5mm jack. Adjust level with the SPEAKER vol- ume knob.

Installation – 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 installa- tion. 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 recep- tion 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 “Strategies for Maximizing RF Reception with the LR-100” on page 7 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 with the LR-100” on page 7 for additional information.

CAUTION: When installing antennas, ensure the antenna is clear of power lines.

NOTES: If the RF signal to the 216MHz 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 trans- mitter).
