Adding a Second Wireless Channel to The Long Ranger
A very popular feature of the Long Ranger is the ability to add a second wireless channel to an existing system in the field. The Lectrosonics Add-On Receiver system was expressly designed for that purpose. The standard system consists of an Add-On receiver, an M175 trans­mitter and a microphone.
The Add-On receiver is supplied with velcro attach­ing strips and is equipped with the necessary cabling for making the connections to the Long Ranger. The receiver is installed on the Long Ranger by performing the following steps as shown in Figure 4:
1) The antenna cable for the Add-On is packed together with screws, lock washers and the velcro strips. The antenna cable is terminated with two ring lugs. Feed the lug end of this cable through the hole in the Long Ranger rear panel upright. Dress the cable along the speaker as shown in Figure 4.
2) Remove and discard the two black Phillips head screws from the bottom of the antenna strip on the right-hand side of the speaker and from the speaker

mounting block. Using the supplied bright screws and lockwashers, connect the shield ring lug to the speaker mounting block. Connect the center conductor ring lug (with the clear insulation) to the antenna. Refer to Figure 4 to help distinguish be­tween the wires. Tighten both screws securely.
3) The Add-On receiver is to be mounted on the Long Ranger upright with velcro. The receiver should be positioned, control panel up, between the horn mounting screw and the screw which secures the battery pack to the upright. Remove the paper backing from one side of the velcro and affix it to the back of the receiver. Remove the remaining paper backing and affix the receiver to the upright.
4) Route the antenna cable through the hole in the rear upright panel, above the battery pack so that the black and white wires reach the speaker mount­ing block. Connect the remaining two cables to the 12V DC OUTPUT jack and the LINE input jack on the control panel.

Initial Adjustments to The Add-On Receiver System
1) Set up the Long Ranger system according to the Initial Equipment Adjustments in the Long Ranger manual.
2) Leave the Long Ranger power turned on. Set both volume controls on the Long Ranger control panel to minimum.
3) Turn the Add-On receiver power switch to “ON.” Check to see that the power lamp comes on.
4) Plug the microphone into the transmitter that is on the same frequency as the Add-On receiver. The plug on the microphone is a twist-lock connector. Make sure there is a good connection. If you are using the head set microphone, turn the white level control knob on the headset fully clockwise (maxi­mum).
5) Install the 9 Volt battery into the transmitter, turn the transmitter on and make sure the red LED on the transmitter glows brightly.
6) Check to see that the green “RF” LED on the Add­On receiver glows steadily. This verifies that the receiver is picking up a good radio signal from the transmitter.
7) This is the most important step in the set up proce­dure. Place the microphone in the exact position where you will be using it. Speak at the same voice level that you will use during actual operation. While you speak, use the supplied screwdriver to adjust the gain control on the transmitter side panel (see page 7) while you observe the MODULATION LEDs on the Add-On receiver front panel. The green LEVEL lamp should flicker or stay lit as you speak. The red LIMIT lamp should blink only on louder words.
8) Adjust the AUXILIARY INPUT VOLUME control on the Long Ranger control panel for the necessary loudness. If the transmitter gain controls have been correctly set on both the Longer Ranger 4 and the Add-On system, both volume control knobs on the Longer Ranger 4 panel will be in about the same position for equal loudness on both systems. It is not unusual, however, that one of the volume controls may need to be set higher or lower than the other one in normal use. Adjust the controls separately for adequate sound levels for each mi­crophone.
Special Note to Dual Channel Users
If you are only using one of the two wireless systems, it is best to use the wireless system built into the Long Rang­er and leave the Add-On receiver turned off. This will prevent unwanted noise, hiss or static that could occur in the unused receiver from entering the Long Ranger.
Rio Rancho, NM
If it is necessary to use the Add-On receiver by itself, turn the WIRELESS MICROPHONE VOLUME control knob on the Long Ranger control panel to minimum. Then set the AUXILIARY INPUT VOLUME for the nec­essary loudness of the Add-On system.

Returning Units for Repair
For timely service, please follow the steps below:
A. DO NOT return equipment to the factory for repair without first contacting us by letter or by phone. We need to
know the nature of the problem, the model number and the serial number of the equipment. We also need a phone number where you can be reached 8 A.M. to 4 P.M. (U.S. Mountain Standard Time).
B. After receiving your request, we will issue you a return authorization number (R.A.). This number will help speed
your repair through our receiving and repair departments. The return authorization number must be clearly shown on the outside of the shipping container.
C. Pack the equipment carefully and ship to us, shipping costs prepaid. If necessary, we can provide you with the
proper packing materials. UPS is usually the best way to ship the units. Heavy units should be “double-boxed” for safe transport.
