9) You may now adjust the WIRELESS MICROPHONE VOLUME control on the control panel to a
level where everyone can hear. You will probably have to do this in several steps. If you
attempt to adjust the volume yourself while standing and transmitting just behind the unit, you
will likely have a "feedback" problem. It is convenient to have another person adjust the
volume while you transmit from a position 20 feet or more behind the unit.
REMEMBER--the transmitter gain control is used only to adjust for proper MOD LEVEL lamp
indications. DO NOT use it to adjust the output volume of the LONG RANGER II speaker. Different
voices and different microphones will usually require readjustment of the transmitter gain control, so
check the adjustment frequently. If several different people will be using the system and there is not
time to make the adjustment for each individual, adjust it for the loudest voice.
USING ADDITIONAL SPEAKERS
CAUTION
ALWAYS TURN THE LONG RANGER II POWER OFF BEFORE PLUGGING IN
OR UNPLUGGING EXTERNAL SPEAKERS
In some cases, the proper coverage of an audience requires a second speaker. The optional H300 is
identical to the LONG RANGER II speaker and can be used to spread the sound over a larger area.
Another optional speaker is the ES300, a column speaker designed for high quality voice or music
reproduction at lower sound levels than the H300 mentioned above. The ES300 is ideal for many
indoor applications where the sound level from the regular horn may be excessive. The H300 and
ES300 will not work well together since the H300 is so much louder than the ES300.
The output jacks for the optional speakers are located on the LONG RANGER II front panel. The
upper and lower jacks operate differently. The upper jack does not disconnect the built-in speaker
when a speaker is plugged into it. This means that the built-in speaker and the auxiliary speaker will
both operate together. The lower output jack disconnects the built-in speaker and powers only the
external speaker. Internal circuits and switching networks keep track of the number of speakers
hooked up and select the amplifier impedance so that the full power of the amplifier is always available.
It is important that you use only an 8 ohm speaker in these jacks. If you are not using Lectrosonics
extension speakers, check the speaker for the proper rating before connecting to the LONG RANGER
II.
The H300 speaker is typically used in conjunction with the built-in speaker to increase sound coverage.
This is done by plugging the H300 into the upper speaker jack. The ES300 column speaker, on the
other hand, will not be nearly as loud as the built in horn, so it is normally used by itself, plugged into
the lower jack on the LONG RANGER II front panel.
When using two external speakers simultaneously, the built-in speaker will be automatically discon-
nected to prevent overload of the amplifier.
In a large area, such as a football field, try to arrange the speakers so that the listeners are not in the
direct sound field of both speakers. If a listener can hear two speakers located at different distances, a
distracting echo effect occurs. Put them together on the 50 yard line and aim them in opposite
directions.
